Temporal Summation – in order to produce a reaction, the first stimulus provides a hump for the second to leap off and reach threshold.
Spatial Summation – when there are two connections though a dendrite and the cell body (first provides hump)
Simultaneous Stimulation – two connections though the cell body make it easy to reach threshold
Facilitation – second ESP is larger than the first, then there is residual calcium in the bouton so the next stimulation has more of an action.
Metabotropic Receptors – presynaptic inhibits release
- postsynaptic slows synaptic responses and may not change membrane potential
- possess membrane spanning regions
- response transduced via G-proteins, then second messenger transduction pathways are activated
- change in membrane potential not required
