8. After spending a night cramming for an exam, and being able to ace the practice questions you were given, you arrive at the exam the next day and only make 50%. Which of the following processes did NOT occur?

a. Consolidation b. Long-term depression c. Hippocampal acquisition d.Cerebellar acquisition
9. Myasthenia gravis is a disease often associated with muscle weakness due to a decrease in the number of nicotinic receptors on the skeletal muscle. A likely treatment for this condition would be: a. Decrease the number of acetylcholine receptors on the postsynaptic membrane. b. Increase the number of adrenergic receptors on the presynaptic membrane. c. Block the action of acetylcholinesterase. d. Give a calcium channel blocker.
5. Most addictive behaviors result in an increased release of the neurotransmitter _____________. The chronically high levels of neurotransmitter cause a(n) _______________ in the number of receptors, which in turn leads to a(n) _____________________ in the drug dosage required to elicit a pleasurable effect.

a. GABA; increase; decrease b. dopamine; increase; decrease c. serotonin; increase; increase d. dopamine; decrease; increase e. serotonin; increase; decrease
2. A patient who complains of changes in her field of vision is seen by an ophthalmologist. It is determined that the visual optics of the eye are fine,however, there is a significant bilateral loss of the peripheral visual field although the right side is most impaired. The underlying cause for this deficit is most likely:

a. damage to the outer parts of the right optic nerve. b. damage to the outer parts of the left optic nerve. c. damage of the right occipital lobe. d. a tumor near the pituitary gland. e. astigmatism of the outer cornea. Please I really need your help!

Explanation / Answer

7. the answer is (d) The left cochlear branch is damaged

because only hearing is affected. and cochlear branch of vestibulocochlear nerve is concerned with hearing.

8. the process of consolidation didnot occur.

the person was able to ace the practise questions because whatever the information was learnt it was stored to short term memory, by process known as hippocampal acquisation.

but it was not registered to long term memory. the process of Consolidation did not take place.

So, the answer is (a) consolidation

9. the answer is (c) Block the action of acetylcholinesterase.

because acetylcholinesterase causes the accelerated decay of acetylcholine receptors therefore, Reversible inhibitors of acetylcholinestrase is given.

5. the correct answer is dopamine, decrease, increase

because high levels of dopamine activates the brain and are responsible for reward motivated behaviour which in turn increases dopamine levels. thats why many drugs work on this principle

2. the answer is (b) bilateral loss of the peripheral visual field

because there is crossover of nerve tracts of optic nerve, that's why left is supplying right side
