Which of the following is evidence against the idea that antidepressant drugs relieve depression simply by elevating neurotransmitter levels? a. The dose of drug necessary for relieving depression is greater than the amount necessary to elevate neurotransmitter levels. b. The drugs quickly affect levels of serotonin and other neurotransmitters but take weeks to alter mood. c. The drugs become less and less effective in relieving depression after weeks of use. d. Several procedures other than antidepressant drugs are also effective in relieving depression.
a. It is a mental condition in which a person has marked or extreme changes in mood. b. Deposit of amyloid proteins and low production of acetylcholine. c. It is that alteration of the state of mind characterized by alteration in serotonin and norepinephrine. d. It is a mental state that generates restlessness and insecurity and is accompanied by symptoms of tension. e.It is a group of chronic and severe mental disorders, often characterized by behaviors that are abnormal for the community, lack of perception of reality and significant social dysfunction. f.Deterioration of the substantia nigra. which as a result, decreases the production of dopamine.

- Name three families of drugs used to treat depression.arrow_forwardThe biogenic amine hypothesis of schizophrenia suggests: Question 43 options: a) That changes in presynaptic neurotransmitter release, and postsynaptic receptor sensitivity, underlies the pathologic process in schizophrenia b) That a decrease in the amount of glutamate in the brain underlies the pathological process in schizophrenia c) That dysfunctional parenting in early childhood is an underlying pathological process towards the development of schizophrenia d) That highly expressed emotion, negative communication patterns, and emotionally involved families increase dopamine release, thereby causing schizophreniaarrow_forwardDiscuss what we know about both of the two main hypotheses (potential targets) for the origin of schizophrenia. LTP is the part of the learning process by which our synapses are strengthened. Using the example of hippocampal circuitry (LP can happen elsewhere in the brain), 1) draw and label the hippocampal circuitry, indicating the direction of the signaling, 2) describe the conditions required for LTP, and 3) draw a graph to show how EPSP magnitude is affected and explain what the long term implications are.arrow_forward
