Synapses and chemical transmission

HideShow resource information
What are MEPPs?
Membrane end plate potentials. they are random release of vesicles causes tiny potentials sub threshold.
1 of 5
What do EPSPs summate to?
Depolarisation of the cell and it firing
2 of 5
What do IPSPs summate to?
Hyperpolarisation and making it harder for the cell to reach threshold.
3 of 5
What is temporal summation?
Lots of EPSPs adding together to reach threshold, from the same pre-synaptic cell. high frequency firing.
4 of 5
What is spatial summation?
The summation of various EPSPs from different pre-synaptic cells to reach threshold.
