From: One cell, two bursting mechanisms. In vivo conditions change the in vitroburst in pyramidal cells of the ElectroLateral Lobe (ELL) of electric fish

Figure 1

Bursting in the ELL pyramidal cells. (A) Representative trace of the in vitro recorded burst. Somatic spikes backpropagate into the dendrites, generating a dendritic spike which will move back into the soma, generating a depolarizing afterpotential (DAP), which will trigger a new somatic action potential The burst terminates with a characteristic doublet, followed by the burst after hyperpolarization (bAHP) (B) Representative trace of the in vivo recorded burst. Here there is no significant decrease in the interspike interval during a burst, bursts do not terminate with a doublet and the bAHP is absent. Also, the somatic spike shape recorded in vivo differs from the one recorded in vitro, with a pronounced hyperpolarization (AHP) following every spike within a burst.
