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 ...

WebBitufted cells are inhibitory and have as target neurons neighboring bitufted cells, multipolar cells and pyramidal cells. 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).
