Figure 2. PV-Rosa and Som-Rosa interneurons in the CA1 HC.

Figure 2

A, live IR Dodt contrast and 505 nm fluorescent (inset) images of a PV-Rosa interneuron in the hippocampal CA1 SP. B, voltage responses to 1 s long hyperpolarizing or depolarizing current steps from the cell shown in A. C, morphologically identified PV-Rosa BC as revealed by (red) biocytin labelling of the cell in (A), counterstained with (blue) Neurotrace 435/455, denoting SO, SP and SR respectively. Fast spiking PV-Rosa BiS interneuron (D–F), fast spiking PV-Rosa SO interneuron (G–I) and Som-Rosa interneuron (J–L) obtained through similar methodology to (A–C). Same distance scales: (A, G, D and J) and (C, I, F and L). Same amplitude and time scales: (B, E, H and K). BiS, bistratified cell; LM, lacunosum-moleculare; SO, stratum oriens; SP, stratum pyramidale; SR, stratum radiatum.
