Values reported for electrophysiological properties and %ΔF/F are means ± SD (with range in parentheses); n = 64 WB and 28 TB for electrophysiological data; for imaging n = 15 WB and 13 TB. 20-80% rise time and half-time (t1/2) fall time are reported as median ± estimated SD. WB, weak bursters; TB, transient bursters; PMA, phorbol 12-myristate-13-acetate; F, fluorescence.
