GABA is commonly introduced as the most prominent inhibitory neurotransmitter in our brains. However, scientists have discovered that GABA does not always lead to the inhibition of a postsynaptic neuron. Explain how this is possible for neurotransmitters more generally. In other words, describe how it is possible for the same neurotransmitter to cause either a depolarizing or hyperpolarizing effect at different postsynaptic synapses. Make sure you clearly explain the reasoning behind your answer.

The table of neurotransmitters below is too simplistic. In reality, one neurotransmitter chemical has multiple actions in the nervous system. How is this possible?
The neurotransmitter acetylcholine is released from presynaptic neurons in response to a nerve impulse and diffuses across the È synaptic cleft, or neuromuscular junction, to a receptor on another neuron or a muscle cell. The nicotinic acetylcholine receptor is a pentamer containing four types of subunits, azßys. Place the events in the correct order, from the release of acetylcholine from a neuron to receptor resensitization: -excited presynaptic neuron releases acetylcholine -acetylcholine diffuses across synaptic cleft or neuromuscular junction -acetylcholine is released from the binding sites -two acetylcholine bind to a receptor; the gate opens -small cations pass through the open pore of the receptor -the plasma membrane of the target cell is depolarized -two acetylcholine are tightly bound to a receptor; the gate is closed -one acetylcholine binds to a receptor; the gate is closed.
Describe the neurotransmitters shown in Section 11.14 in the selected neurotransmitters table. Give examples of how they might occur in the body.
Glutamate's effect when it binds with protein receptors on the post synaptic membrane is to: a. Initiate movement of potassium ions out of the membrane b. Initiate movement of sodium ions into the membrane c. Initiate movement of sodium ions out of the membrane d. Initiate movement of potassium ions into the membrane GABA is an example of an inhibitory neurotransmitter. Drugs that increase the level of GABA are used to treat diseases such as epilepsy where the signal transmission needs to be impaired. The effect of the inhibitory neurotransmitter on the postsynaptic membrane is to: a. hyperpolarize the postsynaptic membrane b. decrease the threshold level c. depolarize the postsynaptic membrane d. maintain the resting potential Calcium is vital for bone growth, but it's also an important part of neural transmission. Calcium is required for the axon terminal to: a. Reuptake the neurotransmitter via exocytosis b. The neurotransmitter to be released by endocytosis c. The neurotransmitter…
Identify the charges (positive/negative) that appear on the inside AND the outside of an axon while at resting state. Explain 2 factors that contribute to the maintenance of this resting state.
Fill out the following table (the 2 columns on the left) LTP LTD Is the following directly associated with the induction of LTP, LTD, both or neither (check both if both apply, and leave blank if neither apply)? a. Increased activity of phosphatase I b. Increased levels of presynaptic Ca²+ c. Postsynaptic hyperpolarization d. Removal of AMPA receptors from the postsynaptic membrane e. Postsynaptic depolarization f. Increased levels of postsynaptic Ca²+ g. Insertion of AMPA receptors into the postsynaptic membrane h. Presynaptic hyperpolarization

Assuming that ESre is a functioning neurotransmitter, what other ESre-specific components would we expect to find (and where) and what purpose do they serve (think about the entire process of synaptic transmission when answering)?
A chemical synapse is a type of synapse that occurs between two neurons and between a motor neuron and skeletal muscle fibers (i.e. at a Neuromuscular junction, NMJ). Compare and contrast the specific events that occur at chemical synapses at these two sites. Describe clearly how they are similar and how they are different, starting at the arrival of a nerve impulse at the pre-synaptic neuron and ending up with the changes observed at the postsynaptic membranes.
