Figure 2

Electrophysiological membrane properties in mossy fibre rosettes. Responses to sub- and suprathreshold depolarization in normal medium (A) and in 10 μM TTX (B). Inset to right in (A) shows suprathreshold responses in normal medium and in TTX (arrow). Inset to right in (B) shows local response in normal medium (arrow) and the effect of TTX (arrow) on the local response. (C) Control sweeps in 10 μM TTX. (D) Addition of 4-AP (1 mM) results in local responses (arrowheads) and a large long lasting spike, which was blocked by Co2+ (E); 3 mM. (A), (B) and (C–E) from two different axons.
