Battle of the Bots - AI gets creative with Brain Hacks

This post is meant to archive my recent exercise of asking  ChatGPT 4o, Perplexity, Gemini+ advanced,  and Anthropic  (which does not offer links to its responses) to expand my  MindBlog's Brain Hacks post into a more complete essay that offers more background and context.  They responded with slightly different styles and impressive results that required tweaking for only a few small errors.  I thought my more concise text was more inviting, and didn't see anything really new, so my next prompt  (which I had asked ChatGPT to edit and improve) said:

"Your responses are well-constructed, but I’m seeking a deeper layer of insight—something that might challenge conventional perspectives or unveil an overlooked nuance. Can you reframe these ideas or introduce a novel approach that stretches beyond familiar interpretations??"

Here things got interesting.  Click the links above and scroll down to the responses to this final prompt to see the results.  The links most likely are maintained as long as I maintain paying accounts to the bots. (Anthropic does not offer links to its exchanges.)

I pass on here what I think is the most original and striking response, from perplexity. It was right on target,  brimming with new perspectives (some of them the subject of previous posts on my MindBlog), and links to a treasure trove of articles and ideas I was not familiar with from seven sources it provided links to.   Its response also provided a potpourri  or more or less relevant graphic images of brains and models.  

Here is the perplexities text, with links to a few of the seven sources it cites, all of which you can obtain directly from perplexity.:

Reframing our understanding of introspective awareness and cognitive modulation requires us to challenge some fundamental assumptions about the nature of consciousness and self-regulation. Let's explore a more provocative perspective that integrates recent neuroscientific findings with evolutionary theory and cognitive science.

The Illusion of Conscious Control

Contrary to the intuitive notion that our conscious mind is the primary driver of behavior and emotion regulation, emerging evidence suggests that consciousness might be more of an observer than a controller. The brain's emotional and regulatory processes often occur before we become consciously aware of them, suggesting that our sense of volitional control might be, to some extent, an illusion.

Consider the possibility that what we perceive as "introspective awareness" is actually a post-hoc narrative constructed by our brain to make sense of unconscious processes. This perspective challenges the traditional view of top-down emotion regulation and suggests a more complex interplay between conscious and unconscious processes.

The Social Evolution of Consciousness

Recent theories propose that human consciousness evolved primarily for social survival rather than individual cognitive enhancement [ref]. This social evolutionary framework suggests that subjective awareness might lack independent causal influence over psychological processes or actions. Instead, it may serve as a communication tool for social interaction and collective decision-making.

This perspective reframes our understanding of self-awareness and emotion regulation. Rather than viewing these abilities as individual cognitive skills, we might consider them as evolved social tools that facilitate group cohesion and cooperation. The ability to regulate emotions, in this context, becomes less about personal control and more about social signaling and coordination.

Neurotransmitter Systems and Emotion Regulation

Recent research has begun to map the overlap between emotion regulation brain networks and specific neurotransmitter systems [ref] [ref]. This approach offers a novel way to understand the biochemical basis of self-regulation. Instead of focusing solely on cognitive strategies or neural networks, we might conceptualize emotion regulation as a dynamic interplay between neurotransmitter systems.

This biochemical perspective opens up new avenues for
understanding individual differences in emotion regulation abilities. It suggests that what we perceive as "willpower" or "self-control" might be more accurately described as the efficient functioning of specific neurotransmitter systems.

The Myth of the Unified Self

Traditional models of self-awareness and emotion regulation often assume a unified, coherent self that observes and controls mental processes. However, neuroscientific evidence increasingly points to a more fragmented view of consciousness and self-hood.

Instead of a single, unified self, we might conceptualize the mind as a coalition of semi-independent processes, each with its own goals and methods of regulation. This "multiple selves" model challenges our intuitive understanding of self-awareness and suggests that emotion regulation might be more about negotiation between different aspects of our psyche than about top-down control.

Conclusion: Towards a New Paradigm

By integrating these perspectives, we can envision a new paradigm for understanding introspective awareness and cognitive modulation. This model would:

1. Recognize the limited role of conscious volition in emotion regulation
2. Emphasize the social and communicative functions of self-awareness
3. Incorporate the biochemical basis of regulatory processes
4. Embrace a more fragmented view of consciousness and selfhood

This approach challenges us to rethink fundamental concepts like free will, personal responsibility, and the nature of the self. It suggests that effective emotion regulation might be less about strengthening willpower and more about understanding and working with the complex, often unconscious processes that shape our emotional lives. By adopting this more nuanced and provocative perspective, we open up new avenues for research and potentially more effective interventions for emotional and cognitive well-being.

MindBlog's Brain Hacks

Introspective awareness and modulation of both ancient and more recently evolved aspects of our cognition:

Brain Hack #1
-The reptilian brain (whose modern descendant is found in the mammalian hypothalamus) generates affective states along axes of arousal and valence, whose states in higher primates can be assessed by introspective awareness.

Brain Hack #2
-The early mammalian emotional brain, whose ability to model a self (correlating with the appearance of the agranular prefrontal cortex), develops the ability to distinguish the difference between being (immersed in) an affective state and seeing (observing) it.

Brain Hack #3
-The appearance in the primate brain of the further ability to imagine the minds of others (correlating with appearance of the granular prefrontal cortex), permits appropriate assignments of agency, being able to distinguish one’s own experience (and problems) from the experience (and problems) of others.

The introspection that enables this ensemble of brain hacks can be strengthened by practice of three fundamental meditation techniques: focused awareness (in which our brain’s attentional mode predominates), open awareness (engaging our default mode network), and non-dual awareness (during which both are muted).  

*************
The above is an early draft text that I will be editing further (like my “Tokens of Sanity” post which has had at least six revisions since it 9/29/2024 posting).  It is trying to meld together and condense threads from my last public lecture and Max Bennett's recent book "A Brief History of Intelligence."  Feedback and comment welcome.

Psilocybin desynchronizes our brains during ego dissolution

From Siegel et al (open source).:

A single dose of psilocybin, a psychedelic that acutely causes distortions of space–time perception and ego dissolution, produces rapid and persistent therapeutic effects in human clinical trials1,2,3,4. In animal models, psilocybin induces neuroplasticity in cortex and hippocampus5,6,7,8. It remains unclear how human brain network changes relate to subjective and lasting effects of psychedelics. Here we tracked individual-specific brain changes with longitudinal precision functional mapping (roughly 18 magnetic resonance imaging visits per participant). Healthy adults were tracked before, during and for 3 weeks after high-dose psilocybin (25 mg) and methylphenidate (40 mg - a placebo in the form of methylphenidate, (Ritalin)), and brought back for an additional psilocybin dose 6–12 months later. Psilocybin massively disrupted functional connectivity (FC) in cortex and subcortex, acutely causing more than threefold greater change than methylphenidate. These FC changes were driven by brain desynchronization across spatial scales (areal, global), which dissolved network distinctions by reducing correlations within and anticorrelations between networks. Psilocybin-driven FC changes were strongest in the default mode network, which is connected to the anterior hippocampus and is thought to create our sense of space, time and self. Individual differences in FC changes were strongly linked to the subjective psychedelic experience. Performing a perceptual task reduced psilocybin-driven FC changes. Psilocybin caused persistent decrease in FC between the anterior hippocampus and default mode network, lasting for weeks. Persistent reduction of hippocampal-default mode network connectivity may represent a neuroanatomical and mechanistic correlate of the proplasticity and therapeutic effects of psychedelics.

How we got to where we are

In the beginning was the cosmos, fundamentally as incomprehensible to our human brains as quantum chemistry is to a dog’s brain.

What our human brains can understand is that our ultimate emergence from countless generations of less complex organisms can be largely explained by a  simple mechanism that tests the reproductive fitness of varying replicants.

Systems that try to predict the future and dictate whether to go for it or scram - from the chemotaxis of bacteria to the predictive processing of our humans brains - have proved to be more likely to survive and propagate.

Modern neuroscience has proved that our experienced perceptions of sensing and acting are these predictions.  They are fantasies, or illusions, as is our sense of having a self with agency that experiences value, purpose, and meaning. Everything we do and experience is in the service of reducing surprises by fulling these fantasies. An array of neuroendocrine mechanisms have evolved to support this process because it forms the bedrock of human culture and language.

We are as gods, who invent ourselves and our cultures through impersonal emergent processes rising from our biological substrate.

Personal and social dysfunctions can sometimes be addressed by insight into this process, as when interoceptive awareness of the settings of  our autonomic nervous system's axes of arousal, valence, and agency allows us to dial them to more life sustaining values and better regulate our well-being in each instance of the present.

We can distinguish this autonomic substrate from the linguistic cultural overlay it it generates, and allow  the latter to be viewed in a more objective light. This is a deconstruction that permits us to not only let awareness rest closer to the 'engine room' or 'original mind' underlying its transient reactive products, but also to derive from this open awareness the kind of succor or equanimity we once found in the imagined stability of an external world.

Hopefully the deconstruction that takes us into this metaphorical engine room makes us more able to discern and employ illusions that enhance continuation rather than termination of our personal and social evolutionary narratives.
