Inspired Brain - 3

Welcome to the Neuro-Christian Martian. We are in the third edition of the Inspired Brain, and in this we are going to discuss Aesthetics and Rehabilitation, and how Aesthetics is a therapy window for Neurorehabilitation. There is a moment that every rehabilitation clinician recognizes. A patient is in front of you. The exercises are ready. The therapy is ready. The technology is ready, and yet nothing moves. Now this is familiar for people who work with people who have significant rehabilitation needs. In this circumstance, the body is present. The brain is awake, but the person is absent. And why is the person absent? Sometimes the patient is anxious. Sometimes exhausted. Sometimes emotionally shut down. Sometimes fragmented cognitively. Sometimes profoundly demortalized. There are so many reasons why the person, while physically present, is absent for the rehabilitation process. And in that one moment, one begins to realize something very important. Rehabilitation is not just about restoring movement. Indeed, it's not about just restoring memory or restoring mental health. It is about restoring participation in life itself. And let me ask you to just sit with that. That the goal of rehabilitation is restoring participation in life itself. And we often say at Bodhikranaik, where we work with a number of patients, that we are trying to restore activities of daily life and quality of life as primary goals in rehabilitation. So, participation in life is such an important goal. Now, rehabilitation has a very strong mechanical model. For decades, it has been conceived as repeat the movement, repeat the exercise, repeat the word, repeat the task. And while repetition matters in rehabilitation, and indeed repetition has an impact on neuroplasticity as well, it's not just about restoring movement. It's about a lot more than that. Neuroscience is teaching us something deeper. The brain does not change equally in every state. The anxious brain learns poorly. The depressed brain disengages. The traumatized brain avoids or bypasses. The fragmented brain struggles to organize experience, think of the person with dementia or think of the person with Parkinson's disease. The exhausted brain shuts down. And therefore, before rehabilitation can truly begin, the system itself may need to open. And that is what we call a therapy window. And this is where neuro-aesthetics enters rehabilitation, not as decoration, not as entertainment, not just as a soft science, but as a biologically meaningful way of altering the brain state. Now, long before neuroscience existed, human civilizations understood intuitively that rhythm regulates, music entrains, story contains, beauty comes, ritual organises, movement transforms, and meaning heals. This is ancient wisdom, and today we are rediscovering it. The raga, the temple, the dance, the poem, the chant, the sculpture. These are not just cultural ornaments. They are technologies of human experience. And this is something that in neuro-aesthetics, we are beginning to rediscover scientifically. Now, in the earlier episodes of the inspired brain podcast, and if you have not listened to them yet, we already have two editions published. We explored the remarkable aesthetic traditions of India. We talked about Tansain and the imaginative power of music. We talked about Tiagaraja and his devotional music architecture. We talked about MSubalakshmi and how her music brought about collective emotional resonance, that great moment when she sang in the United Nations and the whole world stood up to listen. We talked about the cosmic symbolism of Natrajah, and today we have a Natrajah bronze in Sun, no less a place. We talked about Raja Ravi Verma's emotional realism. We talked about Laurie Baker's humane architecture. We talked about Tagore's poetic humanism. Rukmani Devi's embodied re-invention of Bharathanartyam, an old craft, and K. Balachandr the film makers' ability to transform ordinary cinematic objects into profound experience. And what gradually emerged through these discussions was that great aesthetic traditions are not separate from the brain. I have deliberately used a host of Indic examples in trying to describe this. Great aesthetic traditions are deeply entangled with how the brain organizes emotion, memory, movement, identity, attention, and meaning. In our second episode, we talked about how aesthetic experience recruits sensory systems, motor systems, emotional systems, autobiographical memory, reward pathways, intentional systems, and indeed the default mode network itself, the network in our brain that's involved in selfhood and meaning. And a key review in frontiers in psychology describes aesthetic experience as emerging through the interaction of sensory motor systems, emotion, valuation systems, and meaning knowledge systems. So the central question of this master class is if aesthetic experience changes the brain state, can it also change rehabilitation? And for this we start by asking why does art move us? And this is one of the most fascinating questions in neuroacetics. Why does art move us so deeply, not just entertain us, not merely distract us, but genuinely move us? You will see people standing in front of a painting or a sculpture, transfixed for minutes or even hours on an end. Now why does that happen? And indeed there is a paradox of tragic art. People voluntarily seek tragic cinema, melancholic music, sorrowful poetry, emotionally painful narratives. We return repeatedly to songs that ache with longing. We watch films that break our hearts. And of course we cry. We read poetry that intensifies grief rather than escaping it. And somehow very interestingly, we emerge enriched rather than diminished. The psychologist Nancy Etkov of Harvard helps us understand this. She talks about two systems being simultaneously activated. These two systems are usually functionally distinct. On the one hand, our attention is directed outward. Towards the artwork, the melody, the image, the movement, the narrative that we are witness to. Simultaneously, the default mode network also becomes active. And this is involved in autobiographical reflection, memory, imagination, selfhood and future projection. So in other words, while we are absorbed in the artwork, we are also absorbed in ourselves. The artwork outside us begins interacting with memory, identity, longing, hope, grief and meaning within us. And perhaps this explains why aesthetic experiences feel difficult to articulate, emotionally layered and profoundly human. Semilzeki, a pioneer of neuroses that at University College London, used neuroimaging to demonstrate that experiences of beauty, whether they were visual, musical, mathematical or even moral, consistently correlate with activation of the medial orbidofrontal cortex. A piece of music, a painting, a mathematical insight, a sacred image, or an act of moral courage may all initially activate different brain systems, yet they converge in a common area as associated with valuation, emotional meaning and subjective significance and I am talking about the medial orbidofrontal cortex. Beauty, therefore, is not ornamental to the brain, it is one of the ways through which the brain assigns meaning to experience itself, says Samir Zakeh. We started off by talking about the therapy window, now the therapy window is a transient state in which the brain becomes receptive to change, not merely conscious, not merely awake, but emotionally available, attentively engaged, motivationally activated, physiologically regulated and meaningfully connected. Why does this therapy window matters? Rehabilitation often fails, not because the patient lacks intelligence or effort, but because the system itself remains closed. The person may be fearful or dysregulated or apathetic or cognitively overloaded, emotionally exhausted or disconnected from selfhood itself and in such states, even excellent therapy struggles to make impact and this is where aesthetics becomes clinically important. Because aesthetic experience does something remarkable, it opens the system, music can entrain, art can regulate, rhythm can organize, narrative can contain, a mandala painting can structure, reminiscence what we do in people with cognitive impairment, going back and looking at old photographs and telling stories for example, can restore identity, dance can mobilize, literature can reframe. The aesthetic moment opens the system and that statement is not poetic exaggeration. Recent rehabilitation literature increasingly suggests that aesthetic engagement may function as a motivational amplifier and intentional amplifier and potentially even facilitator of neuroplasticity itself. Now the oldest organizational system in the human nervous system may be rhythm because before language, before writing, before philosophy there was rhythm and we have images of humans around the fire causing rhythm to happen and rhythm is there in our heartbeat, in our breathing, in our footsteps, in drumming, in chanting, rhythm is all around us and has been there for millennia. In Parkinson's disease, internally generated movement becomes impaired, people shuffle, they freeze, they struggle to move and the basal ganglia struggles to initiate and sequence movement. Please think about this, your movement has a rhythm or a cadence and that is what is lost in conditions like Parkinson's disease. And yet something extraordinary happens when rhythmic queuing is introduced, a patient who freezes while walking may suddenly become moving in symphony with rhythm because rhythm provides temporal scaffolding, predictive organization and external timing. The brain begins to borrow structure from sound. I was at this conference recently where we were listening to the famous professor Michael thought from Canada who has invented neurological music therapy and he shows this video where there is a person who freezes repeatedly when he is trying to go through the hospital door and all that he does is play a repetitive sound. In the background, not saying anything to the patient and the freezing stops the person walks through the door without any difficulty and the modern scientific basis for NMT comes from his pioneering work and they have helped transform music based rehabilitation from expressive therapy into structured neuroscience. NMT is not simply relaxing music played in the background, it is a structured neuroscience based rehabilitation approach and its methods include rhythmic auditory stimulation, therapeutic instrumental music performance and melodic intonation therapy. These approaches have demonstrated effects in many conditions, Parkinson's disease, stroke rehabilitation, aphasia, the inability to express oneself through language, traumatic brain injury, motor coordination disorders and gate dysfunction or gate disability. And what is especially fascinating is that rhythm appears to bypass purely voluntary systems. It simultaneously recruits your auditory pathways, your cerebellar, timing systems, your motor cortex, the basal ganglia, your attention networks and reward systems. This is not just simple exercise, it is whole brain engagement and that is what rhythm is able to do. In conditions like dementia, we have the erosion of identity. It is a very moving condition and one of the great tragedies is not merely memory loss. It is the gradually erosion of identity. Indeed one thing that makes dementia a fate worse than death is that loss of identity, the loss of self. Families often say she or he is no longer himself or herself but neurosciences teach us something more important. Memories not stored in just one place and identity is not dependent solely on factual recall. Music for example and if you are interested in this please listen also to the podcast on the brain and music which is there earlier in the neuro christian motion. Music engages simultaneously all these different systems, the auditory systems, your emotional memory, autobiographical memory, reward pathways, motor systems you feel like moving or dancing when you listen to music and social memory. Which is why a person who cannot remember names may suddenly sing every word of an old song, a devotional hymn, a wedding melody, a lullaby, a song from youth and in that moment that person with dementia slowly and briefly returns and that is such a profound important and moving experience. Music doesn't therefore just retrieve memory, it retrieves words, a face, a temple, a festival, a younger self, a lost parent, a forgotten emotion. The so much that music can bring back. And this is why reminiscence therapy can be so powerful because it's not just recollection, it is reentry into autobiographical existence. Suddenly the person's posture changes, the facial expression changes, voice changes, engagement returns, identity flickers back into presence and that is rehabilitation at the level of selfhood. Indeed, I had this patient who was really, really crazy about cricket as a game, but after he developed dementia would sit in front of the television and they'd put on cricket for him but he wouldn't react at all. And after he started therapy with us, there was this moment which was a defining change movement that his doctor described to me. on board a Google. obviously not a ball that is frequently bold, and that completely beat the batsman, and the batsman was literally bold, and had to go back to the pevelian. And at that moment, he suddenly came alive, and he said, "Oh, he bowled a googly, just like so-and-so did some years before." And that was the memory coming back, that very specific moment that he cherished as an aficionado of cricket. We have another type of problem which needs rehabilitation. Trauma. Trauma is challenging. Trauma is often difficult to narrate. The traumatized person may relive sensation, avoid memory, lose language, fragment experience, or emotionally become overwhelmed, and it has been described how dramatic states may impair language systems, leaving sensory and emotional traces highly active. And this is where art becomes profoundly important, because art allows expression before language, art provides an intermediate space, a drawing, a symbolic image, a colour field, a mask, a metaphor. These become intermediate spaces between the person and the unbearable experience. The trauma is no longer trapped entirely within the self. It now has form, and once something has form, it can be witnessed. And symbolism allows regulation. This is why aesthetics matters clinically, not because art is pleasant, but because symbolism allows regulation and regulation allows integration. One of the most important insights from neuroesthetic research is that beauty alters attention itself. Aesthetic engagement enhances salience, curiosity, attentional persistence, and motivational engagement, all of which matter a great deal in rehabilitation. Rehabitation is fundamentally an intentional process, and the disengaged brain does not learn well. Aesthetic engagement has that ability to amplify participation, and the brain responds most powerfully to what matters personally to oneself. This is why preferred music, culturally meaningful imagery, autobiographical narratives, devotional memory, emotionally resonant material, all these often produce stronger therapeutic engagement than generic interventions. One of our patients with dementia was a collector, he collected clocks, he collected lithographs, and he also listened to a certain kind of old Hindi film music. And when this is brought to him in therapy, his engagement in therapy is so much better than when we try to engage him through any other generic way of engaging people in therapy. And therefore, we must keep this in mind. The brain responds more powerfully to what matters personally. Dance is another perhaps complete form of neuro rehabilitation. Its simultaneously integrates movement, rhythm, prediction, posture, balance, socials and cranny, emotional expression, and confidence. The individual just doesn't exercise and dance, they participate. And of course, participation changes the way the mind is thinking. For many neurological patients, fear of movement, fear of falling, fear of social embarrassment, fear of failure can make them wheelchair bound or bed bound. This has the capacity to gradually restore confidence in embodiment itself. The body ceases to become merely impaired, it becomes expressive again. The shift is psychologically transformative. Now we've talked a lot about Indic neuroesthetics as part of this masterclass. And there's a reason why I have focused on that. I believe India possesses extra ordinary opportunities here. Our civilization has always integrated rhythm, devotion, movement, ritual, music, narratives, embodied aesthetics within it. And the question is not whether these traditions exist. When we study them rigorously, can we integrate them scientifically? And can we employ them ethically in rehabilitation? Those are the questions. And really, that is the future challenge of being scientifically grounded and yet culturally rooted. Not mysticism, masquerading as medicine, but scientifically grounded, culturally rooted neuro rehabilitation. And this is perhaps where we in India may have something unique to contribute, a civilization that has historically integrated rhythm, movement, devotion, narrative and aesthetics into everyday life, long before the language of neuroscience emerged. Perhaps the greatest mistake we have made in modern medicine is separating healing from meaning. We became technologically sophisticated, but experientially we have become impoverished. And now neuroscience itself is rediscovering something ancient. The brain heals best, not merely through correction, but through engagement. Not merely through instruction, but through emotionally meaningful participation in life. Please remember, several scholars have cautioned against reducing aesthetic experience to mere brain activation maps. I said in the last episode that this is just modern for inology. No aesthetics is most meaningful, not when it diminishes art into circuitry, but when it deepens our understanding of how the brain participates in meaning. This is what neuro-esthetics is teaching us. Beauty is not ornamental to human existence. It is one of the ways through which the brain regulates, remembers, connects, reorganizes and heals, and therefore neuro-esthetics has great potential in rehabilitation. So what then is the inspired brain because you have spent three episodes of this podcast talking about it. It's not merely a brain that appreciates beauty. It is brain which is made receptive to rhythm, to meaning, to memory, to movement, to relationships, and ultimately to transformation. This brings us to the end of this podcast on neuro-esthetics as a therapy window to neuro-rehabitation. If you like what we do here, please subscribe and share. We are on Apple, YouTube and Spotify.
