Cortex

The cortex consists of a more primitive part, the limbic cortex, and a newer part, the neocortex, which is unique to mammals.

It consists of two hemispheres, left and right, which are seperated by the longitudinal fissure, and interact through the corpus callosum.

Each hemisphere is divided into four parts (by bone structure..)

Frontal lobe
Motor and executive functions. Matures the last of all brain regions.
 * Broca's area: Stores motor programs for speaking words. Connected to Wernicke's area through the Arcuate fasciculus (see below).

Parietal lobe
tactile functions
 * PG: Receives input from the dorsal stream (visual cortex), as well as the tectopulvinar system.
 * Posterior parietal region: Receives input from the auditory cortex, for auditory control of movement.

Temporal lobe

 * Hippocampus


 * TE: Receives input from the ventral stream (visual cortex), as well as the tectopulvinar system.


 * Fusiform face area (FFA): Specialized in recognizing things in area of expertise. This includes faces, but also for example car parts if you're a car mechanic.
 * Heschl's gyrus: Contains the primary auditory cortex (A1).
 * Secondary auditory cortex.
 * Wernicke's area.

Occipital lobe

 * Visual cortex

Areas part of multiple lobes

 * Arcuate fasciculus: Connects parts of the temporal and frontal lobe, specifically Broca's area and Wernicke's area.
