A mini EPSP (mEPSP) is the postsynaptic response to release of a single vesicle of neurotransmitter. At the NMJ, what presynaptic and postsynaptic proteins will determine the size of the mEPSP? In other words, what proteins could you inhibit to change the size of the mEPSP at the NMJ? Briefly explain why inhibiting the protein in question would change mEPSP size.

INFORMATION ABOUT IMAGE G FOR QUESTIONS 12-15:
GABAB receptors (GABABRs) are
G-protein-coupled receptors that can be found on both pre- and
postsynaptic neurons. When they are activated by GABA, they can
have a range of effects. For the synapse you are studying in the
following questions, the effects of GABABRs are
indicated in IMAGE G.
You are doing a series of experiments in which you are recording
from the pre- and postsynaptic cell at a synapse. The experiments

Based on your excellent understanding and extensive knowledge of chemical synaptic transmission, EXPLAIN what would happen in response in each hypothetical situation below….Assume you have an experimental set-up with two neurons connected via a chemical synapse – Neuron A is presynaptic and Neuron B is postsynaptic. Also assume that there is a stimulating electrode in Neuron A that brings it to threshold and produces an EPSP in Neuron B. In your answers, include all relevant events between this stimulus and...

The Brain on Mind Altering Drugs Psychoactive drugs alter brain function by acting at synapses in the brain, where they may mimic, enhance, or block the effects of natural signaling molecules (neurotransmitters). The neurotransmitter dopamine plays a particularly important role in creating the dependency aspect of both drug and behavioral addictions. Natural behaviors which enhance survival and/or reproduction, such as eating or engaging in sex, result in a surge of dopamine. Normally, this response helps individuals learn to repeat beneficial...
