WEBIn the pacemaking cells of the heart (e.g., the sinoatrial node), the pacemaker potential (also called the pacemaker current) is the slow, positive increase in voltage across the cell's membrane (the membrane potential) that occurs between the end of one action potential and the beginning of the next action potential.

WEBJul 17, 2023 · The pacemaker potential occurs at the end of one action potential and just before the start of the next. It is the slow depolarisation of the pacemaker cells e.g. cells of the sinoatrial node, towards the membrane potential threshold. This is sometimes referred to as the ‘funny’ current, or If.

WEBPhase 4 - Pacemaker potential. The key to the rhythmic firing of pacemaker cells is that, unlike other neurons in the body, these cells will slowly depolarize by themselves and do not need any outside innervation from the autonomic nervous system to fire action potentials.

WEB11 years ago. A lot of ion channels that are involved in forming die action potential have 2 different gate-mechanisms that can be activated to open them up for their particular ions. Usually the 1 mechanism is very fast and is activated (as shown in the video) very quickly once the membrane depolarizes!
