Evolution of brain is called cephalization. Worms are found to have the simplest brain mechanism and have simple straight forward nervous system i-e head to tail.
Neural Mechanisms refer to structures such as neurons (nerve cells), neural circuits and regions of the brain plus substances such as neurotransmitters and hormones. These regulate behaviour, voluntary and involuntary systems.

Yes, cerebral blood flow is regulated by intrinsic autoregulatory mechanisms in the brain. These mechanisms ensure a relatively constant blood supply to meet the brain's metabolic demands, even when there are fluctuations in systemic blood pressure. Autoregulation helps to maintain stable oxygen and glucose delivery to the brain, supporting its constant function.

The animal with the largest brain in the world is the sperm whale, specifically its brain is the largest of any animal known to have ever existed.

They are, indeed, the most simplest multi-cellular marine animal
In addition to pain receptors in the brain, other mechanisms that can cause headaches include changes in blood flow, chemical imbalances, muscle tension, and nerve irritation.
Proximate mechanisms refer to biological processes that explain how a particular behavior or trait occurs in an organism, focusing on the immediate causes such as hormones, brain activity, or environmental stimuli. These mechanisms are concerned with the immediate mechanisms that underlie behavior, as opposed to ultimate mechanisms which consider the evolutionary reasons behind the behavior.
