"Any process that modulates the frequency, rate or extent of action potential creation, propagation or termination. An action potential is a spike of membrane depolarization and repolarization that travels along the membrane of a cell [goid 1508] [evidence IEA]; An action or movement due to the application of a sudden unexpected stimulus [goid 1964] [evidence IEA]; An action or movement due to the application of a sudden unexpected stimulus [goid 1964] [pmid 11973623] [evidence IMP]; An action or movement due to the application of a sudden unexpected stimulus [goid 1964] [pmid 8298642] [evidence IMP]; A process carried out by the nervous system that is required for the proper control of respiratory gaseous exchange. This process occurs in the respiratory center of the brain in vertebrates [goid 2087] [evidence IEA]; The directed movement of charged atoms or small charged molecules into, out of, within or between cells [goid 6811] [pmid 2155780] [evidence IDA]; The directed movement of chloride into, out of, within or between cells [goid 6821] [pmid 8137830] [evidence IDA]; A process whereby force is generated within muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step. The chemo-mechanical energy conversion step is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis [goid 6936] [pmid 11973623] [evidence IMP]; The series of molecular signals generated as a consequence of a peptide neurotransmitter binding to a cell surface receptor [goid 7218] [pmid 2155780] [evidence IDA]; The process of communication from a neuron to a target (neuron, muscle, or secretory cell) across a synapse [goid 7268] [evidence IEA]; The discharge, by sperm, of a single, anterior secretory granule following their attachment to the zona pellucida surrounding the oocyte. The process begins with the fusion of the outer acrosomal membrane with the sperm plasma membrane and ends with the disperasl of the acrosomal contents into the egg [goid 7340] [evidence IEA]; The series of events required for an organism to receive a visual stimulus, convert it to a molecular signal, and recognize and characterize the signal. Visual stimuli are detected in the form of photons and are processed to form an image [goid 7601] [evidence IEA]; The actions or reactions of an adult relating to the progression of that organism along the ground by the process of lifting and setting down each leg [goid 7628] [evidence IEA]; Any process that modulates the frequency, rate or extent of the process of gaseous exchange between an organism and its environment [goid 43576] [evidence IEA]; Any process by which an organism voluntarily modulates its posture, the alignment of its anatomical parts [goid 50884] [evidence IEA]; Any process that stops, prevents or reduces the frequency, rate or extent of transmission of a nerve impulse, the sequential electrochemical polarization and depolarization that travels across the membrane of a neuron in response to stimulation [goid 51970] [pmid 11973623] [evidence IMP]; The process of communication from a neuron to another neuron across a synapse using the neurotransmitter glycine [goid 60012] [evidence IEA]; A reflex process in which an animal immediately tries to turn over after being placed in a supine position [goid 60013] [evidence IEA]; Any process that modulates the establishment or extent of the inhibitory postsynaptic potential (IPSP) which is a temporay decrease in postsynaptic potential due to the flow of negatively charged ions into the postsynaptic cell. The flow of ions that causes an IPSP is an inhibitory postsynaptic current (IPSC) and makes it more difficult for the neuron to fire an action potential [goid 60080] [evidence IEA]"
