The forebrain (proencephalon) is the largest part of the brain, most of which is cerebrum. ... The thalamusfunctions to relay sensory information to the cerebral cortex and the hypothalamus, regulating visceralfunctions including temperature, reproductive functions, eating, sleeping and the display of emotion.

Hi....
This refers to the primal part of our brain that we actually share structurally with a reptile's brain. Reptiles are, evolutionarily speaking, one of the oldest living organisms; therefore, our 'reptilian brain' is the developmentally oldest portion of the brain, while the forebrain is the most recent. Let's explore this massively advanced, yet evolutionarily young, portion of our supercomputer human brain.
Three regions of the brain
Forebrain
The term forebrain means 'last brain,' or the most recently developed portion of our brain. It controls everything from voluntary movement and the integration of sensory information to all our higher abstract thought, logic, speech, and emotions. Basically, the development of the forebrain is why we humans are so intellectually advanced.
The most obvious structure of the forebrain is the cerebrum, which is divided into a left and right hemisphere by a deep groove called the longitudinal fissure. The right hemisphere is our artistic and creative side, while the left hemisphere is our logical, recollecting side for facts and figures. Generally speaking, the cerebrum is the tissue that most people think of as 'brain tissue' as it is the largest portion of our brain.
Well, both of these tissue types are part of the cerebrum; gray matter is cortex tissue (outer tissue), while white matter is deep tissue (inner tissue) below gray matter. White matter is composed of neurons encased in a fatty white sheath called myelin. This insulates the neurons, aiding in rapid transit of neural signals. gray matter is unmyelinated (without myelin) and so appears gray.
The cerebrum is said to look something like a walnut and has some very unique external features other than its two hemispheres. The cerebrum has many little folds of tissues called gyres. The gyres have depressions between them called sulci (plural for sulcus). These folds and depressions increase cortical surface area. More cortical tissue equals more neurons to transmit thought, emotion, and muscle control signals.
Hope it helps you. :-)
