374. Brain Talk

December 4, 2014

Brain talk is full of words like data, information, computation, processing, knowledge, and other terms of that noble family of academic abstractions. But seldom do we live up to the expectations of the scientists and engineers who treat the brain as if they had designed it themselves by rational means, which they didn’t and never could.

Such terms are descriptors of what neuroscientists want to find, not necessarily of what’s there in the brain to discover. That is, neuroscience is salted with metaphors meaningful to those who study the brain, but many of those same terms are wide of the mark set by instinctual users of particular brains as tools for conducting life as a work-in-progress at every stage.

Most of the mass of the brain is made up of axons (connectors) that lead from one nerve cell nucleus to its terminus, not the nuclei, cortical columns, and synapses that actually perform so much of our mental work. It is the chemical flow between nerve cells that brings minds to life, as facilitated by the travel of ionic potentials from cell bodies to their extremities.

The flow of neurotransmitters across synaptic gaps between nerve cells at myriad points of connection enables those chemicals to get to the right place at the right time to activate or inhibit a comparison in synchrony with other signals so that simultaneous connections are sustained between different regions of the brain, furthering the coherent neural traffic we experience as mind, awareness, or consciousness.

Mind is not confined to the brain but reaches through skilled action to the outer limits of the body and, beyond that, via traffic through nature, culture, community, and family, to the cascade of energy impinging on our sensory organs.

Our minds acquire language and numbers because they are born to language and numbers as two of the cultural media in which they are immersed. They acquire a genome and genetic heritage by being born to particular parents who, at conception, consist of one man and one woman who inhabit a particular niche (nest) in the physical world.

Mind is a collaborative function of brain, body, nature, culture, community, and family. It is the seat of our organic intelligence together with  the many situations and active engagements that make up our lives. I think that to call it a computer or data processor is to miss the point of what the mind actually does and how it operates.
