Ap Psych NeuroTransmitters Flashcards
ACH
- Excitatory
- Muscle movement
- Under supply = Alzheimers disease

ACH
Dopamine
-Inhibitory
-Pleasure, reward, and motivation
-Excess = Schizophrenia
Lack = Tremors in Parkinsons

-Excess = Schizophrenia
Lack = Tremors in Parkinsons
Dopamine
Serotonin
-Inhibitory
-Affects mood, hunger, sleep,and arousal
-Undersupply is linked to depression
-Prozac and other antidepressants raise serotonin
-Inhibitory
-Affects mood, hunger, sleep,and arousal
-Undersupply is linked to depression
-Prozac and other antidepressants raise serotonin
Serotonin
Norepinephrine
-Excitatory
-Helps control alertness and arousal in the fight/flight response
-Has a role in learning and memory retrieval
-Adrenaline Burst of Energy (small amounts in brain)
-Undersupply can depress mood
-Excitatory
-Helps control alertness and arousal in the fight/flight response
-Has a role in learning and memory retrieval
-Adrenaline Burst of Energy (small amounts in brain)
-Undersupply can depress mood
Norepinephrine
Glutamate
-Excitatory
-Involved in memory, learning, and movement
-Oversupply can overstimulate the brain, producing migraines or seizures
-Excitatory
-Involved in memory, learning, and movement
-Oversupply can overstimulate the brain, producing migraines or seizures
Glutamate
GABA
-Inhibitory
-Offsets excitatory messages
-Helps regulate sleep-wake cycles
-Undersupply linked to anxiety, seizures, tremors, and insomnia
-slows down the brain
-Inhibitory
-Offsets excitatory messages
-Helps regulate sleep-wake cycles
-Undersupply linked to anxiety, seizures, tremors, and insomnia
-slows down the brain
Gaba
Substance P
-Excitatory
-Bodys perception of pain and send pain signals to the brain
-Takes info injury to the spinal cord then to the brain
-Too much = chronic pain, depression, and anxiety
-Excitatory
-Bodys perception of pain and send pain signals to the brain
-Takes info injury to the spinal cord then to the brain
-Too much = chronic pain, depression, and anxiety
Substance P
Endorphins
-Natural opiates that are released in response to pain and vigorous exercise
-Natural opiates that are released in response to pain and vigorous exercise
Endorphins
Agonists
-Speed up neural processes
-block the re-uptake process
-cause an over-release or absorption of a neurotransmitter
-Speed up neural processes
-block the re-uptake process
-cause an over-release or absorption of a neurotransmitter
Agonists
Antagonist
-Slow or stop the transmission of a neurotransmitter
-Bind themselves to receptors on the dendrite, not allowing a message to be passed on
-Slow or stop the transmission of a neurotransmitter
-Bind themselves to receptors on the dendrite, not allowing a message to be passed on
Antagonists
3 types of neurons?
-Sensory neurons
-inerneurons
-Motor neurons

-inerneurons
-Motor neurons
The 3 types of Neurons
Sensory Neurons
Carry information from the body to the brain
Carry information from the body to the brain
Sensory Neurons
Interneurons
-Found In the spinal cord & brain
-interpret incoming information and determine the next course of action
-Found In the spinal cord & brain
-interpret incoming information and determine the next course of action
Interneurons
Motor Neurons
Carry information from the spinal cord or the brain to the rest of the body in order to initiate behavior

Motor Neurons
Reflexes
The exception to the general pathway of neural activity are reflexes

Reflexes
Process of a reflex
Sensory - Spinal cord - Motor
