  • Values in this table are means ± SD. The resting potential for AF cells is listed as “NA” (not applicable) because they fired action potentials spontaneously. See methods for definitions of the various parameters presented here. The number of cells for SN, ASN, AF, and LTS are 31 cells from 14 birds, 21 cells from 16 birds, 9 cells from 8 birds, and 4 cells from 4 birds. SN, spiny neuron; ASN, anomalous spiny neuron; AF, aspiny, fast-firing neuron; LTS, low threshold spike neuron. In some cases, the data needed to measure all parameters for all cells were not available. In such cases, the number of cells contributing to the measurement is indicated in the following footnotes: a  n = 20;b  n = 3; c  n= 30; d  n = 18; ande  n = 20.
