The process in which membrane potential changes in the depolarizing direction from the resting potential, usually from negative to positive. For example, the initial depolarization during the rising phase of an action potential is in the direction from the negative resting potential towards the positive membrane potential that will be the peak of the action potential. Any process that modulates the establishment or extent of a membrane potential, the electric potential existing across any membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane. Any process that modulates the establishment or extent of the excitatory postsynaptic potential (EPSP) which is a temporay increase in postsynaptic potential due to the flow of positively charged ions into the postsynaptic cell. The flow of ions that causes an EPSP is an excitatory postsynaptic current (EPSC) and makes it easier for the neuron to fire an action potential. The process of communication from a neuron to a target (neuron, muscle, or secretory cell) across a synapse. Any process that modulates the establishment or extent of the postsynaptic membrane potential, which is generated by changes in the membrane potential of the post synaptic neuron that receives information at a synapse. The presynaptic neuron releases neurotransmitters into the synaptic cleft which bind to receptors on the postsynaptic neuron. After being bound by the neurotransmitters, these receptors can open or close an ion channel, allowing ions to enter or leave the cell and therefore altering the membrane potential of the postsynaptic neuron. Any process, involved in skeletal muscle contraction, that modulates the establishment or extent of the excitatory postsynaptic potential (EPSP). Excitatory postsynaptic potential (EPSP) is a temporay increase in postsynaptic potential due to the flow of positively charged ions into the postsynaptic cell. The flow of ions that causes an EPSP is an excitatory postsynaptic current (EPSC) and makes it easier for the neuron to fire an action potential.
