Figure 5


Fig. 5. Intracellular recordings showing the lower threshold and the shorter range of stimulations of the Aff. (A,B) The responses to Aff (A) and PF (B) stimulation following increased stimulus intensity. (C,D) Amplitude of the synaptic potential as a function of stimulus intensity for Aff (C) and PF (D) stimulation. The stimulus intensity in each experiment (N=6) was normalized by the threshold of detectable response. Each symbol corresponds to the behavior of one neuron for both inputs. Note that the range of Aff stimuli is considerably shorter than that of PF stimulation. (E) Superimposed normalized traces of the synaptic response to Aff and PF stimulation. Note the fast rise time of the Aff synapse compared to the PF synapse. (F) Increase in PF stimulus intensity evoked a prolonged response that can support the generation of a short burst of action potentials.
