The workings of the brain
An open Borg skull showing the brain.
The brain is the part of the central nervous system that is the center for regulation and control of the body. The brain is made up of neurons that make use of chemical reaction and electricity by way of neurotransmitters to function. Each brain has a unique circuitry pattern.

The mind is also the house of consciousness, subconscious, metaconscious, thought, memory, emotion, the ability to dream and the powers of extrasensory perception by way of psionic energy.

Dopterians, Breen and Ferengi have a four lobed brain structure, which can not be read by telepathic species. (TNG: "The Loss", DS9: "The Forsaken")
In many, but not all species, hallucination is a sign that the brain is malfunctioning. One exception state the Denobulans, who hallucinate to reduce stress.

In 2253, Leonard H. McCoy developed a medical procedure involving brain tissue engrafting. (VOY: "Lifesigns")
Spock's brain was removed by the Eymorg in 2268. (TOS: "Spock's Brain")
Julian Bashir performed brain surgery on Bareil Antos in 2371. Parts of his brain were replaced artifically. It allowed Bareil to live long enough to help Winn Adami sign the Bajoran-Cardassian Treaty. (DS9: "Life Support")
