The Brain’s Reward Center And Synced Movement

What is it about brain matter that gives rise to consciousness? In particular, the neuronal correlates of consciousness (NCC) - the minimal neuronal mechanisms jointly sufficient for any conscious experience.

Consider this question: What must happen in your brain for you to experience a toothache?

The whole brain can be considered an NCC because it generates experience continually.

• When parts of the cerebellum, the "little brain" underneath the back of the brain, are lost to a stroke or otherwise, patients may lose the ability to play the piano, for example.  But they never lose any aspect of their consciousness. This is because the cerebellum is almost wholly a feed-forward circuit. There are no complex feedback loops.
• The spinal cord and the cerebellum are not enough to create consciousness. Available evidence suggests neocortical tissue in generating feelings.
• The next stages of processing are the broad set of cortical regions, collectively known as the posterior hot zone, that gives rise to conscious perception. In clinical sources of causal evidence, stimulating the posterior hot zone can trigger a diversity of distinct sensations and feelings.
• It appears that almost all conscious experiences have their origin in the posterior cortex. But it does not explain the crucial difference between the posterior regions and much of the prefrontal cortex, which does not directly contribute to subjective content.

The synchrony between the brain activity of a performer and his audience shows insights into the nature of musical exchanges: we dance and feel the same emotions together, and our neurons fire together as well. This is especially true when it comes to the more popular performances.

Synchronous brain activity was localized in the left hemisphere of the brain (temporal-parietal junction). This area is important for empathy, the understanding of others’ thoughts and intentions, and verbal working memory used for expressing thought.

The right brain hemisphere is most often associated with the interpretation of musical melody.

In the right hemisphere, synchronization is localized to areas involved in recognizing musical structure and pattern (the inferior frontal cortex) and interpersonal understanding (the inferior frontal and postcentral cortices).

• The non-mirror-style self. We are used to seeing ourselves mirror-style. When you move your left hand, it will always be flipped when you view yourself in a mirror. On Zoom, you lift your left hand, and the opposite side moves on Zoom. This feels disorientating. Thankfully, Zoom has fixed this.
• The perfect self-contingency detection. When you lift your hand in front of a mirror, there is no lag in the image. Now you feel your arm stir and see it move a few seconds later. No wonder we stare at ourselves.
• Glitchy wifi magnifies the slight asynchrony. The response delay disrupts your feeling of connection with another person. You can't read them, and they can't read you.
• A documented phenomenon is that we accurately recognize neutral expressions on other faces, but we misidentify our own expressions. We see our own expression as unfavorable most of the time.
