An inhibitory postsynaptic potential (IPSP) is a kind of synaptic potential that makes a postsynaptic neuron less likely to generate an action potential. [1] The 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.
The opposite can happen when the opening of ion channels results in the flow of negatively charged ions, like chloride (Cl −), into the cell, or positively charged ions, like potassium (K +), to flow out of the cell, creating inhibitory postsynaptic potentials (IPSP) that hyperpolarize the cell membrane, decreasing the likelihood of an action ...
The IPPS-A implementation is a partnership between the Assistant Secretary of the Army for Acquisition, Logistics, and Technology and the Army G-1 with Program Executive Office Enterprise Information Systems and Technology and Business Architecture Integration.
The way that synaptic potential is created involves the theories behind potential difference and current through a conductor. When an action potential fires at the dendritic spine where the action potential is initiated from the presynaptic terminal to the post synaptic terminal.

Graph displaying an EPSP, an IPSP, and the summation of an EPSP and an IPSP. Graded membrane potentials are particularly important in neurons, where they are produced by synapses—a temporary change in membrane potential produced by activation of a synapse by a single graded or action potential is called a postsynaptic potential.
The reversal potential of the GABA B-mediated IPSP (inhibitory postsynaptic potential) is −100 mV, which is much more hyperpolarized than the GABA A IPSP. GABA B receptors are found in the central nervous system and the autonomic division of the peripheral nervous system .
The International Maritime Organization (IMO) states that "The International Ship and Port Facility Security Code (ISPS Code) is a comprehensive set of measures to enhance the security of ships and port facilities, developed in response to the perceived threats to ships and port facilities in the wake of the 9/11 attacks in the United States".
