ACH
- Excitatory
- Muscle movement
- Under supply = Alzheimers disease

ACH
Dopamine
-Inhibitory
-Pleasure, reward, and motivation
-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

-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

Antagonists
3 types of neurons?
-Sensory neurons
