excitatory, inhibitory, agonist, or antagonist

dopamine binds to receptors on the postsynaptic cell, increasing the entry of Na+ ions

excitatory

multiple EPSPs increase the cell membrane at the axon hillock, causing Na+ to rush into the cell

excitatory

a neurotransmitter binds to postsynaptic receptors, opening an ion channel that allow K+ to flow out of the cell

inhibitory

alcohol increases the inhibitory activity of GABA on the postsynaptic cell

agonist

prozac increases the presence of serotonin, leading to increased mood

agonist

chlorine binding to a postsynaptic receptor results in an IPSP

inhibitory

pipitol prevents neurons from creating glutamate, a commonly excitatory neurotransmitter

antagonist

adenosine naturally reduces the release of acetylcholine

antagonist

THC mimics the body’s own production of anandamide

agonist

a cell experiences a single EPSP at the same time as multiple IPSPs, resulting in the membrane hyperpolarizing. together the effect is:

inhibitory

methamphetamine forces dopamine out of vesicles, increasing the amount of dopamine released by the presynaptic cell

agonist

atropine prevents the release of acetylcholine, and can help maintain proper heart rate

antagonist

thc mimics anandamide, leading to increased dopamine release

agonist

caffeine blocks the inhibitory effects of adenosine, increasing wakefulness

antagonist
