Question

49. A. Early attempts to control temporal lobe epilepsy involved the removal of portions of the        hippocampus. In one famous example (that of H.M.), the patient developed __________.

            Because of this, a contemporary approach for the treatment of epilepsy is to           __________:

            a. retrograde amnesia/remove the amygdala.

            b. anterograde amnesia/sever the corpus callosum.

            c. Parkinson's disease/remove the basal ganglia.

            d. Korsikoff's syndrome/remove the nucleus accumbens.

            e. Schmirnoff's syndrome/remove the bottle.

B. Learning is probably best defined as __________:

a. a relatively permanent change in genotypic behavior due to phenotypic modification.

b. a relatively permanent change in gene frequencies over generational time.                    

c. a relatively permanent change in behavior and cognition due to experience and not due to disease, injury, drugs, or development.

d. a multi-generational adaptive response.

e. a permanent change in behavior due to the interaction between classical and operant conditioning.

C. Carl Lashley determined that specific memories were not necessarily stored in distinct      locations within the cortex, supporting a model of memory storage termed __________:

a. long term potentiation.

b. long term depression.

c. equipotentiality.

d. homogeneity.

Answer 1

49.A. answer - a ( retrograde amnesia / remove the amygdala)

As hippocampus is responsible for long term memory - removal will lead to retrograde amnesia

Removal of amygdala causes 70-80 decrased seizure in epilepsy cases.

B. Answer - c (a relatively permanent change in behaviour and cognition due to experience and not due to disease, injury, drugs, or development.

C. Answer - c - Equipotentiality

It is the capacity of functional part of brain to carry out function of destructed part.
