WebBitufted dendrite-preferring cell IPSPs were insensitive to the benzodiazepine type 1 agonist zolpidem but were reduced by an α5-selective inverse agonist, IAalpha5, suggesting that IPSPs elicited by bitufted dendrite-preferring cells are mediated by α5-subunit–containing GABA A receptors. Consistent with these findings, zinc also reduced ... Webarbors suggests that bitufted cells can control the excitation within a cortical column and, possibly in the supragranular lay-ers, also between columns (Kaiser et al., 2001). The efficacy of synaptic connections between pyramids and bitufted cells is low (Reyes et al., 1998), but EPSPs strongly facil-
