Document Summary

What occurs at the neuron and behavioural level when this event occurs. One is at the level of the tissue and one is at the level of the organism. Event/drug that activates a receptor; mimics or increases the effect of the neurotransmitter (ts) Event/drug that blocks a receptor; inhibits the effect of the neurotransmitter (ts) Doesn"t let a neuron do what it wants to do. Independent of the neurotransmitter action (can be excitatory or inhibitory) Remember: transmitter substances can be excitatory or inhibitory. *one thing that influences the influence of release of ts it depends on size of ap. Input of epsps keeps coming this causes the aps to keep firing and deplete vesicles of ts and theres no more so you cant elicit more effect on the communication neuron. Ts supply will deplete before restoration and synthesis can replace and/or repackage the ts. When an axon from another neuron onto an axon and sends aps: presynaptic facilitation negative.
