Figure 1From: One cell, two bursting mechanisms. In vivo conditions change the in vitroburst in pyramidal cells of the ElectroLateral Lobe (ELL) of electric fishBursting 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.Back to article page
