Compare and contrast EPSPs and IPSPs. How do they contribute to triggering an action potential?
What will be an ideal response?
EPSPs (excitatory postsynaptic potentials) are signals that hypopolarize postsynaptic neurons, making the neuron less negative (moving closer to a membrane potential of zero), and making an action potential more likely to occur. IPSPs (inhibitory postsynaptic potentials) are signals that hyperpolarize postsynaptic neurons, making those neurons more negative in charge (moving farther from a membrane potential of zero), and making action potentials less likely to occur. EPSPs and IPSPs can be summed through temporal and spatial summation to have more complex effects on action potentials being triggered.
