Coronal cut of the sheep brain (plate 11) Diagram

Lateral ventricle

Generates CSF via choroid plexus, The CSF made circulates around the midline of the thalamus and hypothalamus is collected at the roof of the mesencephalon

Corpus callosum

A brain structures that joins the two hemispheres together

Septum

A solid aggregation of nerves that is considered to be part of the limbic system

Columns of the fornix

It curves downwards and posterior towards the hypothalamus and pass through the septum where many of the fibers of the fornix terminate at; As a sidenote, the fornix has been associated with regulation memories

Anterior commissure

A round bundle of nerve fibers that are situated anterior to the anterior columns of the fornix; they connect the right and

left anterior temporal lobes as well as subcortical structures that are involved with olfaction

Optic chiasm

It is the location where ganglia retina cells from the eyes cross to the contralateral side

Globus pallidus

Involved in voluntary movement; It has an inner and outer segment associated with ith

Caudate nucleus

Part of the basal ganglia;

In terms of function, there is much to indicate

that the caudate participates in higher order motor and even cognitive function. Among other things, the caudate nucleus

is thought to be involved in the initiation and termination of movement within a meaningful context. It is also thought to

allow us to form new associations between perceptions and actions, and to break links between well established stimulusresponse

chains in order to make different responses to the stimulus and the same response to different stimuli.

Internal capsule

This is formed by massive fiber bundles that represent not only the total output of the cortex to the brainstem and spinal

cord, but also the fibers that stream from the thalamus toward the cortex. This fiber system is called "capsule" because it

appears to encapsulate the thalamus.

Extreme capsule

Found as somewhat diffused white fibers between the claustrum and the insula; the more dorsal part of the visual connection system for cortex areas; more ventral part of the capsule is formed by fibers connected to the frontal to the temporal lobe

external capsule

Contains fibers that connect the putmen to the cortex; most of the fibers that make up this capsule are mostly fibers that project from the neocortex to the putmen

Putamen

Part of the basal ganglia; appears to be involved in higher order activity of the somatic musculature
