Watch this video (http://openstaxcollege.org/l/summation) to learn about summation. The process of converting electrical signals to chemical signals and back requires subtle changes that can result in transient increases or decreases in membrane voltage. To cause a lasting change in the target cell, multiple signals are usually added together, or summated. Does spatial summation have to happen all at once, or can the separate signals arrive on the postsynaptic neuron at slightly different times? Explain your answer.

A loss-of-function mutation in the ion channel responsible for thegeneration of end-plate potentials results in a diminished permeabilityof the ion channel. 1) How would you experimentally test the effect of the mutation on thefunctional properties of the cell (synapse)? You should discuss the typesof postsynaptic responses and physiological parameters you couldmeasure.
Absolute refractory periods in axons: Result from conformational changes in voltage gated K channels after opening O Result from Cl channel induced hyperpolarization O Result from Ca dependent phosphorylation of K channels Result from conformation changes in voltage gated Na channels after opening O Result from Ca dependent phosphorylation of Na channels

In terms of function when a presynaptic neuron receiving input from a nearby inhibitory neuron, it can be inferred that the both neurons firing won't be synchronized activation of the inhibitory neuron is nullified activation of the presynaptic neurotransmitter release is enhanced this type of interaction represents a regulatory input of neuronal activation
Which statement is true regarding chemical neurotransmission? O An IPSP closer to the soma will diminish the effects of an EPSP on a dendrite Chemical neurotransmission is mediated by gap junctions All neurotransmitter receptors are located on the postsynaptic cell membrane Neurotransmitters remain in the synaptic cleft indefinitely
apucreceptors ava ble at the synapse are reflected in this number. Question 2: In this chapter, we discussed a GABA-gated ion channel that is permeable to Cl. GABA also activates a G-protein-coupled receptor called the GABA receptor, which causes potassium-selective B channels to open. What effect would GABAB receptor activation have on the membrane potential? GABAB receptor activation causes potassium-selective channels to open. As a result this bringhs the
