Validation of NeuroElectro database measurements with collection of raw data. A: representative targeted recording of a hippocampal CA1 pyramidal cell (“CA1, PC”), showing anatomical position and morphological reconstruction (left), response to hyperpolarizing and depolarizing rheobase and suprathreshold step current injections (middle), and action potential waveform (right). Anatomical scale bar = 200 μm. B–D: same as A for main olfactory bulb mitral cell (B; “MOB, MC”), main olfactory bulb granule cell (C; “MOB, GC”), neocortical basket cell (D; “Ctx, BC”), and striatal medium spiny neuron (E; “Str, MSN”). F: summary of targeted in vitro recordings and comparison to text-mined, metadata-adjusted values from NeuroElectro. D, dorsal; P, posterior; M, medial; A, anterior. Morphological reconstructions (except the representative granule cell) have been moderately thickened to aid visualization of thinner processes.
