The integration of these conflicting signals determines the ultimate fate of the neuron. Neurotransmitter Diversity and Receptor Specificity The diversity of communication is staggering, with various neurotransmitters such as dopamine, serotonin, and acetylcholine playing distinct roles in mood, reward, and muscle activation.
Postsynaptic Neuron Function at the Synapse: How Signals Are Integrated and Transmitted
In most cases, the synapses occur on the dendrites or the main cell body, or soma, of the target neuron. An excitatory postsynaptic potential (EPSP) depolarizes the cell, moving it closer to the threshold required to generate an action potential.
This binding event triggers a change in the electrical charge of the receiving cell, initiating a new signal that will travel down its axon to the next destination in the neural network. Inhibition: The Balance of Neural Activity Not all signals prompt the postsynaptic neuron to fire; the nature of the response is categorized as either excitatory or inhibitory.

Conversely, an inhibitory postsynaptic potential (IPSP) hyperpolarizes the cell, making it less likely to fire. If the sum of excitatory signals outweighs the inhibitory signals within a specific timeframe, the neuron reaches its threshold and fires an action potential.
