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.

Question 14 2.5 pts A. Use several sentences to describe Ca2+-based mechanisms underlying neurotransmitter release. B. Assume you are recording from the squid giant synapse and are able to stimulate the presynaptic neuron and record the response in the postsynaptic neuron. Describe a set of experiments (and their results) to demonstrate that Ca2is both necessary and sufficient for neurotransmitter release.

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
described below...

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...

A series of mutations caused a DNA sequence to change from ATCGATAA to GGCGGTAA. Which of the following sequences do you think will take longer to replicate? Thoroughly explain! A scientist is interested in studying the unfolded protein response in an unknown (has not been previously studied) mutant cell line. The scientist treats the cells with heat to cause the proteins in the ER to denature. Unfortunately, the scientist does not measure any chaperone activity in the ER. The scientist...

How do neurons conduct information? (Please note: this question refers only to events occurring during the time from the receipt of an external signal by a single neuron to the time this information is relayed to the next neuron or muscle. It does not include anything relating to the initial sensory neuron that stimulated the neuron in question, or the subsequent neuron or muscle that this neuron stimulates.) a. What kind of protein “senses” incoming information at the post-synaptic membrane?...
