How dopamine drives brain activity

Dopamine

Dopamine

Dopamine plays many roles in the brain. It is related to movement, motivation, and reinforcement of behavior.

Dopamine appears to exert significant effects in two regions of the brain's cortex, the motor cortex, and the insular cortex. The insular cortex is critical for many cognitive functions related to the perception of the body's internal states, including physical and emotional states.

Dopamine

Dopamine plays many roles in the brain. It is related to movement, motivation, and reinforcement of behavior.

Dopamine appears to exert significant effects in two regions of the brain's cortex, the motor cortex, and the insular cortex. The insular cortex is critical for many cognitive functions related to the perception of the body's internal states, including physical and emotional states.

Tracking dopamine

Dopamine, like other neurotransmitters, helps neurons communicate with each other over short distances. Most of the brain's dopamine is produced in the midbrain by neurons that connect to the striatum.

High dopamine concentrations do not make the neurons more active. However, they do make the neurons remain active for a more extended period of time, suggesting a longer response to the reward. It may have something to do with how dopamine promotes learning, which is one of its main functions.

Long-range effects

Researchers set out to determine if dopamine might affect more distant locations in the brain.

The regions that showed the most significant surges in activity in response to dopamine were the motor cortex and the insular cortex. The findings can help researchers understand the effects of dopamine in the human brain, including its roles in addiction and learning.

Searching For Physical Footprints

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?

Neuronal Correlates of Consciousness (NCC)

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.

Dancing to the same emotions

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.

Music and the right hemisphere of the brain

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).
