Question
Chapter 12.10, Problem 30WDYL
Summary Introduction
To determine:
How acetylcholine generates either EPSP or an IPSP.
Concept introduction:
A neurotransmitter is chemical substances which are released by the axon terminals at the time of arrival of the nerve impulses. These neurotransmitters are stored in synaptic vesicles. These vesicles then fuse with the sending membrane which results in the release of neurotransmitter into the synaptic cleft.

- How are EPSPs produced? IPSPs?arrow_forwardAssume presynaptic excitatory neuron A terminates on a postsynaptic cell near the axon hillock and presynaptic excitatory neuron B terminates on the same postsynaptic cell on a dendrite located on the side of the cell body opposite the axon hillock. Explain why rapid firing of presynaptic neuron A could bring the postsynaptic neuron to threshold through temporal summation, thus initiating an action potential, whereas firing of presynaptic neuron B at the same frequency and the same magnitude of EPSPs may not bring the postsynaptic neuron to threshold.arrow_forwardWhat is the approximate magnitude of the IPSP (how many mV)?What is the approximate magnitude of the EPSP (how many mV)?If the IPSP had not occurred, what would be the difference between the EPSP and the thresholdrequired to produce an action potential?arrow_forward
- Is atropine a competitive or a non-competitive antagonist of acetylcholine-induced responses? How did you reach this conclusion?arrow_forwardWhat effect would you expect an antagonist that targets the voltage sensing domain of perisynaptic calcium channels of an inhibitory interneuron have on the firing frequency of a finically active neuron that interneuron synapses onto? Explain in detailsarrow_forwardIf an axon ([Na+]in = 200 mM) is bathed in solution consisting of [Na+]out = 10 mM, will there be an action potential if a supra-threshold stimulus (changed Vm to -20 mV with opening of Na channels) is injected into the axon?arrow_forward
- What might prevent an EPSP from stimulating action potentials?arrow_forwardIf a pre-synaptic cell releases a large amount of excitatory neurotransmitter into the synaptic cleft, how will that affect the PSPs? Does that large release ensure that the postsynaptic cell will initiate an action potential, and what role does the axon hillock play in this process/decision?arrow_forwardWhat is the nicotinic acetylcholine receptor? Where is it expressed?arrow_forward
