Spiking and synaptic parameters of FS basket interneurons match the parameters obtained for PV⁺ basket interneurons. A, The layer of labeled PV cells in the CA region of the hippocampus. B, Paired recordings from PV⁺ interneurons connected to pyramidal neurons. Top to bottom, DIC image showing the recording configuration, an epifluorescence image of the same field of view showing the presynaptic PV⁺ cell, and an overlay. C, IPSC amplitudes are similar for PV⁺ and FS cells. D, Spiking frequencies are similar for PV⁺ and FS cells. E, CAs are similar for PV⁺ and FS cells. F, Coefficients of variation are similar for PV⁺ and FS cells. G, PPRs are similar for PV⁺ and FS cells. H, The 3D plot depicting the three parameters, CF, CA, and PPR, shows that PV⁺ and FS interneurons fall within the same cluster. Data collected from nine PV⁺ cells.
