Which of these is not a sx of schizophrenia?
a. Positive sx (hallucinations, delusions)
b. Negative sx (loss of motivation, asocial
c. Mania
d. Lack of Salience
e. Cognitive sx (d1R mediated)-inability learn
c. Mania
mania is a sx of bipolar; salience means knowing what’s important when you are getting a lot of input into your brain
Matching: DA projects from VTA and substantia nigra; what do they mediate?
a. VTA to frontal cortex 1. movement
b. Sub. Nigra to striatum 2. Motivations, emotions
c. VTA to nucleus accumbens 3. ADRs/prolactin release
d. Hypothalamus projection 4. Rewards/psychosis
a. VTA to frontal cortex - Motivations, emotions
b. Sub. Nigra to striatum - movement
c. VTA to nucleus accumbens - Rewards/psychosis
d. Hypothalamus projection - ADRs/prolactin release
True or False?
According to dopamine hypothesis, high levels of DA to the frontal cortex is what causes the cognitive side effects
False.
It is low levels of DA from the VTA to the cortex that cause cognitive side effects. High levels of DA in mesolimbic pathway that cause the psychosis and positive sx
According to the glutaminergic hypothesis, which NT is there a deficiency of in the cortex to cause an increase in DA upstream?
a. Glutamate
b. GABA
c. serotonin
d. Dopamine
GABA
NMDA receptors on the GABA receptor are not working properly according to this hypothesis causing less GABA to be released. This doesn’t allow for inhibition of the glutamate neuron that releases glutamate and allows for DA to increase on a dopaminergic neuron (excitatory) in the limbic neuron. It is a PROBLEM from the NMDA receptor though, which causes the deficiency in GABA. This explains positive, negative, cognitive sx; it can also explain the DA hypothesis
Which receptor antagonism causes the tremors in chlorpromazine (Thorazine)
a. 5ht2
b. D1R
c. D2R
d. D5R
D2R
Which of these are reasons why it takes a few weeks for a typical antipsychotic to decrease DA levels?
a. Remodeling
b. Action on autoreceptors
c. Increasing breakdown of DA
Remodeling.
If it acts on autoreceptors it is increasing DA levels in the synapse which wouldn’t help what we want since we want antagonism
