brainstem, limbic system, cerebral cortex
The brain region that seems to have the oldest evolutionary history is the brain stem. The brain stem is located at the brain's base and is joined to the spinal cord. The brain stem contains the midbrain, pons and medulla oblongata.
It can be proven to be impossible to fully understand the how the brain works. For any finite size brain, there are only a finite number of possible neuron firings and so a finite number of possible thoughts. If there's no restriction to the size of the brain, then there are countably infinitely many neuron firings so there's that many thought. Let's consider special class of thoughts of thinking of a sequence of 1s & 0s. Since there are countably many brain actions, there are countably many sequences that we can think of. Suppose you have a sequence of sequences, then we can construct a new sequence as follows. It's 1st digit is opposite the first digit of the first sequence, it's 2nd digit opposite the second digit of the second sequence, the 3rd digit opposite the third digit of the 3rd sequence and so on. If we fully understand how the brain works, we should be able to determine which brain action makes which thought of a sequence of 1s and 0s. That would mean that by thinking of a sequence of that entire set of brain actions, we should then be able to translate brain actions into thoughts and count all the sequences we can think of. Doing so would then enable us to think of a new sequence but we didn't count it, a contradiction. Therefore it's impossible to fully understand how the brain works.
The association areas are the last regions of the brain to fully develop their myelination, which helps with faster and more efficient neural communication. These areas are responsible for higher cognitive functions like reasoning, problem-solving, and decision-making in the brain.
While neurons in the brain cannot regenerate, certain regions of the brain can exhibit neuroplasticity, allowing for new connections to form and for other areas to compensate for lost function. Brain cells can also replenish and regenerate in specific regions, such as the hippocampus, which is important for memory and learning. However, extensive regeneration of brain tissue, such as after a traumatic injury, is limited.

The prefrontal cortex is considered the newest part of the human brain from an evolutionary perspective. It is responsible for higher-level cognitive functions, such as decision-making, planning, and self-control.
Drugs can act in various regions of the brain to exert their effects.
