Figure 6.

Sequence of excitation of compartments in a model of a basket cell neuron resulting from a single pulse of stimulation. Presynaptic spikes are generated in one (panel A, left top insets shows branch marked in red color) or simultaneously in both distal axonal branches (panel B, left top insets branches marked in red) and propagate antidromically to the soma and later to the dendritic compartments. The second PAP occurs at the axon terminal approximately 1.5 ms after the initial spike and results from orthodromic propagation that follows somatic depolarization (yellow). The pulse timing and duration are indicated at the bottom by the blue trace. In panel A, the PAP is generated in the left distal axonal branch (turquoise) and propagates antidromically towards the distal axon (red) and next to the right axonal branch (green and pink) and somatic/dendritic compartments (yellow/black). Current pulse amplitude in 6 mA; duration 0.3 ms
