World Brain Day 2026: Consciousness is not a philosophical problem. [it is connected to electrical and chemical signals in the cns]
Therapies for mental disorders can broadly be divided into two categories: those that target electrical signaling and those that target chemical signaling.
Simply put, antidepressants, antipsychotics, and anxiolytics target [for] chemical signaling. Electrical, magnetic, and ultrasound stimulation target [for] electrical signaling. While there might be interchanges at times, these are mostly obtainable.
So, if improvement in mental disorders involves both electrical and chemical signaling, it's possible to postulate that variations in either or both contribute to the mind, and therefore to consciousness.
There is no conscious function that does not directly involve electrical and chemical signaling.
Wherever there is a major function [memory, emotion, feeling, or the modulation of internal senses] neurons are in charge.
But neurons operate through their electrical and chemical signals.
This means that whether it's the cerebellum, the brainstem, the thalamus, or the cerebral cortex, electrical and chemical signaling is directly responsible for neural function.
So even if consciousness is primarily associated with the thalamus, cerebral cortex, and other regions, electrical and chemical signaling are the central.
Conceptually, human consciousness can be defined as the interactions of electrical and chemical signals within clusters of neurons, with the features of those interactions giving rise to functions and experiences.
Functions can be summarized as experiences, while the features, or attributes, determine how those functions are expressed. Subjectivity is one such attribute.
To make progress on consciousness, the brain has to be the focus, not just as an organ, but specifically with electrical and chemical signals.
This isn't a dualism (or any other "-ism") argument, at least for now. The question is: what components are in the brain, and what mechanisms do they use that could plausibly give rise to consciousness?
So while philosophy has been valuable, neuroscience-based theorizing seems like the more promising direction for understanding consciousness, human intelligence, and others
