|
EPSP |
Excitatory postsynaptic potentials. Eg sodium, membtane becomes more positive |
Na+ |
|
|
IPSP |
Inhibitory postsynaptic potentials. Membrane become more negative. |
Cl- |
|
|
Divergent |
One incoming fiber stimulates increasing number of fibers. Amplifying circuit. |
|
|
|
Convergent |
Opposite of Divergent, strong stimulation or inhibition. |
|
|
|
Reverbrating(oscilation) circuit |
Chain of neurons containing collateral synapses with previous neurons in the chain. |
|
|
|
Parallel |
Incoming neurons stimulate several neurons in parallel arrays. |
|
|
|
Serial processsing |
Input travels along one pathway to specific destination. |
|
|
|
Parallel processing |
Input travels along several pathways in CNS. |
|
|
|
Temporal Summation |
One or more presynaptic neurons transmit impulses in rapid fire. |
|
|
|
Spatial summation |
Postsynaptic neuron is stimulates by a large number of terminals at the same time. |
|
|
|
Absolute refractory period |
The period from the opening of the na+ channels until the na+ beging to reset to their original state. |
|
|
|
Relative Refractory period. |
The interval following the absolute refractory period. Most sodium have returned to their resting state. |
Permeable to sodium. |
