Indicate how neurons can selectively block or facilitate one input while leaving others unchanged

Are changes in the resting membrane potential of a cell targeted by a neuron

Are changes in the threshold of a cell targeted by a neuron

Both raise the axon hillock of the post-synaptic structure to AP threshold

Indicate how voltage-gated Ca⁺⁺ modulate responses in post-synaptic neurons 

it acts as a current sink for EPSPs occurring at the dendrites.

it is the region which is closest to the nerve terminal.

the voltage-gated Na⁺ channels in this region do not become refractory.

it has the highest density of voltage-gated Na+ channels.

the voltage-gated Na⁺ channels in this region possess the ability to adapt to a maintained pre-synaptic input.

Chemically and voltage-gated potentials

Pre-synaptic facilitation and Pre-synaptic inhibition

Excitatory and Inhibitory post-synaptic potentials

Facilitatory, excitatory and Inhibitory potentials

Excitatory and Inhibitory end plate potentials

Long-term changes in the pre-synaptic terminal depolarization

Short-term changes in the pre-synaptic terminal depolarization

Short-term changes in the post-synaptic adaptation

Short-term changes in pre-synaptic facilitation or inhibition

Short-term changes in the excitatory post-synaptic potential

Post-synaptic potentials flow electrotonically with loss of current

Voltage change produced by synapses on the soma can be excitatory or inhibitory

Voltage change produced by synapses on dendrites have to reach a much lower trigger threshold for an AP

Voltage change produced by synapses on dendrites can be excitatory or inhibitory

Summation can only occur at the axon hillock so that a synapse closer to the hillock is more efficient

Spatial summation

Population coding

Spatio-temporal summation

Temporal summation

Distributed summation

EPSPs involve voltage-gated ion channels

EPSPs do not involve voltage-gated ion channels

EPSPs involve voltage-gated cation channels

EPSPs involve mechanically-gated cation channels

EPSPs involve voltage-gated antion channels

It allows for the most selective blockade of input to the target neuron

It allows for a decrease in the threshold to produce an AP

It allows for an increase in the release of transmitter to the neuron

It prevents any further propagation of all information received at the dendrites

It prevents any further propagation of all information received at the terminal
