Station 2 – Part of right cerebral hemisphere removed
For Your Information:
During development, the corpus callosum begins in the anterior part of the brain and grows posteriorly. Some of the anterior brain tissue is dragged posteriorly with the growing corpus callosum. In the model, this tissue is represented by the green stripes on the corpus callosum. In the adult brain, this tissue connects the anterior brain to other parts of the brain. The rest of this tissue will be seen as we “dissect” the brain further.

The red strip extending along the line of attachment of the roof of the third ventricle to the thalamus is the stria medullaris of the thalamus. It connects the hypothalamus, prepiriform cortex, and other parts of the brain to the habenular nuclei of the epithalamus (Gray/39 p. 384). Little is known of the physiological functions of the habenular nuclei. They are the focus of integration of diverse olfactory, visceral, and somatic afferent paths. They may be involved in the control of sleep mechanisms. They play a role in the regulation of visceral and neuroendocrine functions. Damage to them results in changes in metabolism, and endocrine and thermal regulation. Some of the fibers are commissural and connect the amygdaloid complexes and hippocampal cortices. 5 6
