postsynaptísku

Postsynaptic refers to the region of a synapse that receives a signal from the presynaptic neuron. When an electrical or chemical signal arrives at the presynaptic terminal of a neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then diffuse across the cleft and bind to specific receptors located on the postsynaptic membrane. This binding event can either excite or inhibit the postsynaptic neuron, influencing its likelihood of firing an action potential. The postsynaptic neuron is characterized by the presence of these receptors and the intracellular machinery that responds to neurotransmitter binding. The structure and function of the postsynaptic region are critical for synaptic transmission, allowing for the communication of information between neurons. The efficiency and plasticity of synaptic connections, which are fundamental to learning and memory, are heavily dependent on the properties of the postsynaptic neuron.
