  • axon
  • Propagation of an action potential on the membrane of an axon. (brainscape.com)
  • Refers to the state of an axon in the repolarizing period during which a new action potential cannot be elicited (with some exceptions), because gate 2 of sodium channels, which is not voltage sensitive, is closed. (brainscape.com)
  • Play media In physiology, an action potential occurs when the membrane potential of a specific axon location rapidly rises and falls: this depolarisation then causes adjacent locations to similarly depolarise. (wikipedia.org)
  • If the sum of the input signals into one neuron surpasses a certain threshold, the neuron sends an action potential (AP) at the axon hillock and transmits this electrical signal along the axon. (wikipedia.org)
  • Backpropagating action potentials cannot occur because after an action potential travels down a given segment of the axon, the voltage gated sodium channels' (Na+ channels) m gate becomes closed, thus blocking any transient opening of the h gate from causing a change in the intracellular [Na+], and preventing the generation of an action potential back towards the cell body.

  • miniature
  • Bernard Katz pioneered the study of these mEPSPs at the neuromuscular junction (often called miniature end-plate potentials) in 1951, revealing the quantal nature of synaptic transmission. (wikipedia.org)
  • response
  • The Bienenstock, Cooper and Munro model (BCM model) proposes that a certain threshold exists such that a level of postsynaptic response below the threshold leads to LTD and above it leads to LTP. (wikipedia.org)
