The three evolutionary levels of the brain are the reptilian brain (responsible for basic survival functions), the limbic system (associated with emotions and memory), and the neocortex (involved in higher cognitive functions such as reasoning and problem-solving).
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.
The brain is affected first when blood glucose levels drop. The brain relies on glucose as its primary source of energy and is sensitive to fluctuations in blood glucose levels, which can lead to symptoms such as dizziness, confusion, and fainting.
Benzodiazepines can indirectly affect dopamine levels in the brain by increasing the activity of the neurotransmitter gamma-aminobutyric acid (GABA). GABA inhibits the release of dopamine, leading to a decrease in dopamine levels.
Several factors can influence the levels of dopamine in the brain, including genetics, environmental factors, stress, diet, and drug use. Dopamine levels can also be affected by certain medical conditions and medications.
An evolutionary trade-off occurs when there is a compromise between two traits that cannot be optimized simultaneously. For example, investing resources in growing a larger brain may come at the expense of producing fewer offspring. Evolutionary trade-offs are the result of limited resources and competing selective pressures.

Generally accepted with their own sets of evolutionary traits
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.
The brain stem is often referred to as the "reptilian brain" because it is the most primitive part of the brain, responsible for basic life functions such as heart rate, breathing, and reflexes. This term highlights its similarities to the brains of reptiles, which possess similar structures that govern survival instincts and automatic behaviors. The concept is rooted in the triune brain theory proposed by Paul MacLean, which categorizes the brain into three evolutionary layers, with the brain stem representing the oldest evolutionary component.
The more classification levels that two organisms share, the more characteristics they have in common

Yes, drugs can increase serotonin levels in the brain by either blocking the reuptake of serotonin or by mimicking its effects.
The brain is affected first when blood glucose levels drop. The brain relies on glucose as its primary source of energy and is sensitive to fluctuations in blood glucose levels, which can lead to symptoms such as dizziness, confusion, and fainting.
Drugs can affect serotonin levels in the brain by either increasing or decreasing the amount of serotonin that is released or by changing how the brain processes serotonin. This can lead to changes in mood, behavior, and overall brain function.

Diabetes is a disease caused by low insulin levels. Type 1 & 2 diabetes deal with insulin produced in the pancreas. Within the past decade, researchers have discovered insulin is also produced in the brain. Type 3 diabetes corresponds with low levels of insulin produced in the brain.
