Document Summary

Describe the process in which a neural impulse travel down one axon, making sure to specify chemical substances involved and how that affects the charge within the cell at each stage. Use a graph to show how the membrane potential changes as a function during the different stages of the process. Describe the difference between neurotransmitters that have excitatory and inhibitory effects, using examples of neurotransmitters of each type to clarify your description. Inhibitory neurotransmitters reduce the probability that a neuron will have an action potential; gaba and serotonin are examples c). Draw the following neural circuits (using the notation taught in class) and then say what would happen if they were stimulated as specified. i). Answer: a would receive an action potential and since it is an excitatory neuron, b would therefore be stimulated ii). A circuit that shows convergence between neurons that send excitatory neurotransmitters.
