Question

Adopt the view that the brain is indeed composed of separate but interacting and intercommunicating functional parts, each of which serves only one major function. Think about what might happen if one of the following “functional parts” were damaged beyond repair.

Frontal cortex, Occipital cortex, Cerebellum, Hippocampus, Amygdala

Then decide on which of these parts you think is the most important and explain why you think the part you chose is the most important. Include the following information.

Identify and provide a 1-2 sentence description of the most usually described function of this area.

Describe at least one additional function of this area which is not typically discussed in a textbook. Include a reference to your source of information. (Cite using APA format).

Describe the relationship between this area and another area of the brain; that is, describe the type of information being sent (efferent) and received (afferent) between the two areas. For this point, you may refer to any part of the brain.

Explanation / Answer

Hippocampus- organ located within the brain's medial temporal lobe and is responsible for the maintainence of emotions in the human body.

Frontal Cortex - one of the most important parts of the brain that is resposnible for the cognitive properties of the body.

Amygdala- This is an integrative center of emotions of the human body

Occipital Cortex- This is the visual processing area of the brain where it is responsible for vision of a person

Cerbellum- This part of the nervous system is responsible for processing the infoprmation of spinal cord and is resposnible for maintaining all the other voluntary body movements such as balancing, posture, movement etc.

All the mentioned parts are quite important in their own way but cerebellum is the one without which it would be highly difficult to survive. This is all because of the fact that the other parts are just responsible for controlling and maintaining emotions which can be sorted out again and also if the vision of a person is lost he can survive efficiently as well.

But when the cerebellum gets damaged, there would be no passage of information from the spinal cord of the body and all the other body movements are stopped. With that it would be rather difficult to live.

One additional function of cerebellum is that it has half of the neurons of the body and these are specialized cells that transmit information via electric signals.

The Basal Ganglia is just an another sun cortical part like the cerebellum that receive input from wide areas of the cerebral cortex and direct their output.

Afferent tracts are placed in all cerebellar peduncles, by which they reach all cerebellar parts where the largest inputs are the cortical inputs, interpolated in the pontine nuclei.

Efferent tracts run to the thalamus, red nucleus and reticular formation nuclei are localized in the superior cerebellar peduncles brachia conjunctiva

Afferent of Basal Ganglia

1. Corticostriate

2. Thalamostriate

3. Nigrostriate

Efferent

1. Striatopalladia

2. Striatonigral

3. Pallidofugal fibers
