A subset of NGC derives from the CGE. A, Fluorescence image of two fate-mapped cells derived from Mash1 fate mapping (tamoxifen induction at E14.5) that exhibit neurogliaform morphology and that are nNOS-negative. B, Neurolucida reconstruction of a fate-mapped NGC in Mash1BAC-CreER/RCE:LoxP mouse after induction at E12.5. Scale bar: 50 μm. C, Voltage responses of cell shown in B to three current step injections (−200 pA, just above threshold, and twice the current for just above threshold). D, Phase plot of the voltage response shown in C to twice the current for just above threshold. Inset illustrates overlaid action potentials; scale bar: 10 mV, 2 ms.
