Neurotransmitters Flashcards
bad levels of dopamine cause?
DA-low levels cause Parkinson’s
schizophrenia is caused by too much DA
low levels of Norepinephrine cause?
depression
what does serotonin control?
sleep and aggression
bad levels of serotonin cause?
eating disorders and OCD (low levels)
Gamma-aminobutyric acid
produce inhibitory PSP’s
Glutamate
- excitatory
- involved in learning and memory
endorphins
mimics opiates and induce pleasure
acetylcholine (ACh)
activates motor neurons controlling skeletal muscles, contributes to the regulation of attention, arousal, and memory. some receptors are stimulated by nicotine
dopamine (DA)
contributes to the control of voluntary movement and pleasurable emotions. decreased levels associated with Parkinson’s disease. overactivity at DA synapses is associated with schizophrenia. cocaine and amphetamines elevate activity at DA synapses
Norepinephrine (NE)
contributes to the modulation of mood and arousal. cocaine and amphetamines elevate activity at NE synapses
serotonin
involved in the regulation of sleep and wakefulness, eating, aggression. Abnormal levels may contribute to depression and OCD.
GABA
serves as a widely distributed inhibitory transmitter. Valium and similar antianxiety drugs work at GABA synapses
Endorphins
resemble opiate drugs in structure and effects. contribute to pain relief and perhaps to some pleasurable emotions
