Cortical bitufted interneurons which are GABAergic and contain the cotransmitter somatostatin (Reyes et al. 1998) are located predominantly in supragranular layers 2/3 and layer 4 and are the target cells for excitatory axon collaterals of pyramidal neurons (28, 36).Frequency-dependent facilitation is characteristic for the …
http://scholarpedia.org/article/Interneurons 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 ...
