A postsynaptic neuron is bombarded by synaptic inputs from several hundred presynaptic neurons. However, this neuron does not appear to transmit an impulse. Propose an explanation of why this could occur
What will be an ideal response?
The input from each presynaptic neuron may be either excitatory or inhibitory. The postsynaptic neuron integrates this information into a single effect known as neural integration. In this situation, the IPSPs outnumber the EPSPs, and the neuron is inhibited from generating an action potential. The numerous IPSPs hyperpolarize the postsynaptic neuron.
