You are studying an antagonist to the GABAAreceptor. Explain what an antagonist is and how it works. What will be the effects, on a neuron, when you add this antagonist? Draw a series of (4 or 5) normal action potentials and then a series of (4 or 5) action potentials showing the effects of this antagonist. (the point of this diagram is for you to show what is happening differently with the antagonist present).

You are studying a ligand-gated ion channel. The ligand is a neurotransmitter. Upon binding the neurotransmitter, the ion channel opens and Na+ flows into the cell. The receptor is found on the dendrites of frog neurons. You are going to use one of the patch-clamp variations to study the effect of (1) the neurotransmitter and (2) second (and separately) the effect of an antagonist. Explain the patch-clamp technique variation you would use and why. Explain how you will study the...

Q1: a) Describe how a galvanic cell works and include a fully labelled sketch. Explain clearly what is occurring in each ‘side’. b) You add Mg to a beaker containing HCl(aq) and a gas is produced. Explain, chemically, what is happening and write a balanced equation for the reaction, including how many electrons are transferred. How could you harness the reaction to do useful work? c) The equation ΔGo = -nFEo is also applicable to half-reactions. Using standard reduction potentials,...

1. Draw a set of EPSPs and IPSPs that will initiate an action potential. You must use at least 4 IPSPs to reach threshold and initiate an action potential. Use a normal action potential graph as an example. Each EPSP is +6 mV and each IPSP is -2 mV (I totally made these numbers up). You can put the EPSP and IPSP in any order, alternating or, however. Resting potential is -70mV and threshold is -50 mV. An example of...

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...

2. Long-term Potentiation is a process that strengthens the transmission of a single synapse in a circuit. This is achieved when pre-synaptic cells and post-synaptic cells fire action potentials at the same time. Usually multiple pre-synaptic cells synapse onto one post-synaptic cell, increasing the probability of inducing an action potential in the post- synaptic cell. You may need to refer to your textbooks or online resources for this question, as we do not cover this in explicit detail in class....

UNIT Section Date REVIEW Check Your Understanding Critical Thinking and Application Questions 1 Neurons are amitotic, which means that after a certain stage, they do not divide further. Most tumor cells are characterized by a rapid rate of mitosis. Considering this, of which cell types (neurons or neuroglia) must brain tumors be composed? Why? 2 You are examining a neuronal process and you find that it generates action potentials. Is this an axon or a dendrite? How can you tell?...
