The possible role of glutamatergic pathways in the pathophysiology of schizophrenia has been highlighted in recent years. Specifically, there has been talk of possible glutamatergic hyperfunction. How would this hyperfunction affect the dopaminergic pathways?
Discuss 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.
The 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 schizophrenia
