When people talk about training, they generally mean taking an amorphous mind and shaping it into something. It is the sort of thing that goes on at … - Michael S. Gazzaniga

A clearer picture of what is happening in the brain during non-REM sleep,14 during sleepwalking,15 and during confused arousals16 has been achieved through neuroimaging and EEG. It appears that the brain is half awake and half asleep: the cerebellum and brainstem are active, while the cerebrum and cerebral cortex have minimal activity. The pathways involved with control of complex motor behavior and emotion generation are buzzing, while those pathways projecting to the frontal lobe, involved in planning, attention, judgment, emotional face recognition, and emotional regulation are zoned out. Sleepwalkers don’t remember their escapades, nor can they be awakened by noise or shouts, because the parts of the cortex that contribute to sensory processing and the formation of new memories are snoozing, temporarily turned off, disconnected, and not contributing any input to the flow of consciousness.

As I have mentioned earlier, emotional states appear to transfer between the hemispheres subcortically, and this transfer is not affected by severing the corpus callosum

Schopenhauer’s framing kicked the problem of consciousness onto a much larger playing field. The mind, with all of its rational processes, is all very well but the “will,” the thing that gives us our “oomph,” is the key: “The will … again fills the consciousness through wishes, emotions, passions, and cares.”14 Today, the subconscious rumblings of the “will” are still unplumbed; only a few inroads have been made. As I write these words, enthusiasts for the artificial intelligence (AI) agenda, the goal of programming machines to think like humans, have completely avoided and ignored this aspect of mental life. That is why Yale’s David Gelernter, one of the leading computer scientists in the world, says the AI agenda will always fall short, explaining, “As it now exists, the field of AI doesn’t have anything that speaks to emotions and the physical body, so they just refuse to talk about it.” He asserts that the human mind includes feelings, along with data and thoughts, and each particular mind is a product of a particular person’s experiences, emotions, and memories hashed and rehashed over a lifetime: “The mind is in a particular body, and consciousness is the work of the whole body.” Putting it in computer lingo, he declares, “I can run an app on any device, but can I run someone else’s mind on your brain? Obviously not.”15
