3 types of cortical areas

Brodmann’s areas (52)

What areas describe cortical function ?

Basal nuclei

A group of interconnecting nuclei within the forebrain, diencephalon and midbrain that have a critical role in initiating and controlling voluntary movement

Limbic system

Interconnected and interacting structures that play a role in drive related and emotional behaviours

Diencephalon

Several sets of paired structures on either side of the 3rd ventricle (Thalamus, hypothalamus, pineal body and habenular nucleus)

Midbrain

Pair of cerebral peduncles that provide linkages between the cerebellum, basal nuclei and hemispheres (substantia nigra, superior and inferior coliculi and red nucleus)

Hindbrain

Pons, medulla oblongata and cerebellum
