Cerebral Cortex

encompasses Neocortex, Archicortex and Paleocortex. Usually seen as covering cerebral hemispheres

Efferent

Conduction of a signal away from a cell

functional MRI

Use of Magnetic Resonance Imaging to study brain function

Gray Matter

Gyrus

Convoluted ridges on surface of the brain

Homunculus

Model representing amount of neuronal cortex devoted to specific areas of body

Kinaesthesia

Perception of relative body positions

Lateral Geniculate Nucleus

Part of thalamus that acts as visual relay station

Neocortex

most recent layer of cortex to evolve, covers cerebral hemispheres

Paleocortex

2nd oldest layer of cerebral cortex to evolve, includes olfactory cortex

Sulcus

Grooves observed on surface of the brain
