The Brain

Question 1

Name the three types of cerebral cortex

Answer 1

-Neocortex (densely packed) (divided by gyri and sulci)
-Hippocampus (memory) (in each temporal lobe)
-Olfactory cortex (sensory)

Question 2

Identify the lobes of the cerebrum, the primary motor, sensory, visual and auditory cortices, the hippocampus, the insula cortex, the basal ganglia, the amygdala.

Answer 2

images

Question 3

Describe the types of axons that project through the corpus callosum and the internal capsule

Answer 3

Corpus callosum - commissural fibres
Internal capsule - projection fibres

Question 4

Recall the role of the thalamus in connecting the cerebral cortex to various CNS regions.

Answer 4

-Thalamus connects the neocortex to CNS regions
-Over 50 nuclei, the relay station acts as a gateway to the cortex, connecting to the neocortex via projection fibres.
