Question

place each of the descriptions into their appropriate bin: epsp (excitatory post-synaptic potential) or ipsp (inhibitory post-synaptic potential) or both.

Answer 1

1. A change in the membrane potential of a neuron that makes it more likely to fire an action potential

-EPSP

2. A change in the membrane potential of a neuron that makes it less likely to fire an action potential

-IPSP

3. A graded potential that is generated in the post-synaptic neuron in response to the release of neurotransmitter from the pre-synaptic neuron

-Both EPSP and IPSP

4. A potential that is generated in the post-synaptic neuron in response to the binding of a neurotransmitter to a receptor

-Both EPSP and IPSP

5. A potential that is generated in the post-synaptic neuron in response to the opening or closing of ion channels in the post-synaptic membrane

-Both EPSP and IPSP
