WebThe opposite of an inhibitory postsynaptic potential is an excitatory postsynaptic potential (EPSP), which is a synaptic potential that makes a postsynaptic neuron more likely to generate an action potential. IPSPs can take place at all chemical synapses, which use the secretion of neurotransmitters to create cell to cell signalling. WebThese neurotransmitters bind to receptors located on the postsynaptic membrane of the lower neuron, and, in the case of an excitatory synapse, may lead to a depolarization of the postsynaptic cell. An excitatory synapse is a synapse in which an action potential in a presynaptic neuron
WebJan 27, 2024 · Most inhibitory synapses in the brain and spinal cord use either γ-aminobutyric acid (GABA) or glycine as neurotransmitters. The predominant precursor for GABA synthesis is glucose, which is metabolized to glutamate by the tricarboxylic acid cycle enzymes (figure 2.3). The enzyme glutamic acid decarboxylase (GAD), which is found …
