IPSPpotentiaaleja
IPSPpotentiaaleja, or inhibitory postsynaptic potentials, are transient hyperpolarizations of the postsynaptic membrane of a neuron. These potentials occur when a neurotransmitter binds to receptors on the postsynaptic neuron, leading to the opening of ion channels permeable to anions, such as chloride ions. The influx of negatively charged chloride ions into the cell makes the inside of the neuron more negative, thus increasing the membrane potential's distance from the firing threshold.
IPSPs are a crucial mechanism for regulating neuronal excitability. By counteracting excitatory postsynaptic potentials (EPSPs), which
