Thalamus.
interconnected with the cerebral neocortex, sensory pathways(besides olfaction) are relayed to the cortex passing through the thalamus acting as a gatekeeper and modulator.
Name this anatomical component. State its function.
Mamillary bodies.
Function:
- recollective memory, as transmitted from hippocampus—>fornix—>mamillary bodies.
Name this and state its function.
Inferior Colliculus.
Function: channel for auditory signals and processing, in order for auditory information and visual information to be integrated together.
Name this and state its function.
Superior colliculus.
Function:
- The orientation of the head with eye movement( can be also response due to somatosensory and auditory information).
Name this, state its function and its composition.[3 marks].
Tegmentum.
Function:
- Co-ordination of sensorimotor information.
Components:
- Substanti nigra, Red nucleus and Periaqueductal gray.
Name this and state its function(2 marks).
Anterior commissure.
Function:
- Interhemispheric communication of visual, auditory and olfactory information between temporal lobes. Whilst connecting both hemispheres along the midline.
Name and state its function.
Hypothalamus.
Function:
- Homeostasis and modulation of the endocrine system through the pituitary gland.
Name this and state its function.
Cerebral aqueduct.
Function:
allows cerebrospinal fluid(CSF) to flow between third ventricle and fourth ventricle.
Name this and state its function.
Optic chiasm.
Function:
- The intersection of visual information from the optic nerve.
Name this and state its function.
Pineal gland.
Function:
- To produce melatonin in response to light-dark cycles, increasing levels in response to night.
Name this and state its function.
Fornix.
Function:
- Direct pathway of processes such as memory, cognition, emotion and sexual responses to the hippocampus.
