Whether the “Influx of Na + ions inside the membrane of post synaptic neuron” will cause excitatory postsynaptic potential (EPSP) or inhibitory postsynaptic potential (IPSP). Introduction: Signal transduction in neurons depends upon the resting potential of the membrane of the neuron. Signals are sent by a wave of depolarization. This wave of polarization develops only when depolarization potential is more than the threshold potential. This potential is termed as action potential of the membrane.

You would expect the membrane potential to depolarize if the extracellular K+ concentration were to [increase, decrease] ______________. a.) hyperpolarize, decrease b.) depolarize, decrease c.) depolarize, decrease d.) hyperpolarize, increase

We know the action potential threshold regulates whether a neuron fires an action potential or not. What sets this threshold? Is the action potential threshold the same for all neurons? Why or why not?

If a postsynaptic cell has synapses from five different cells, and three cause EPSPs and two of them cause IPSPs, give an example of a series of depolarizations and hyperpolarizations that would result in the neuron reaching threshold.
