Expand description

BK channel neuron — WB base + voltage- and Ca2+-dependent K+ current.

BK (big conductance, MaxiK) channels are activated by both membrane depolarisation and intracellular Ca2+. They have the largest single- channel conductance (~250 pS) of any K+ channel. During action potentials, Ca2+ influx through voltage-gated Ca2+ channels activates BK, producing fast repolarisation and a prominent fast AHP.

Key mechanism for:

  • Fast afterhyperpolarisation (fAHP): rapid spike repolarisation
  • Action potential narrowing: BK shortens AP duration
  • Burst termination: accumulated Ca2+ activates BK, ending burst
  • High-frequency firing: fast repolarisation enables rapid recovery
