Properties of horizontal axo-axonic cells in stratum oriens of the hippocampal CA1 area of rats in vitro.
Local-circuit gamma-aminobutyric acid (GABA)ergic interneurons constitute a diverse population of cells, which remain poorly defined into functionally distinct subclasses. Traditionally, dendritic and axonal arbors have been used to describe cell classes. In the present report, we characterize a set of hippocampal interneurons, horizontal axo-axonic cells, located in stratum oriens. They displa...
متن کاملMembrane potential and intracellular Ca2+ oscillations activated by mGluRs in hippocampal stratum oriens/alveus interneurons.
Metabotropic glutamate receptors (mGluRs) are expressed heterogeneously in hippocampal interneurons, and their signal transduction cascades remain largely unclear. We characterized an oscillatory response activated by the mGluR agonist 1S,3R-1-aminocyclopentane-1,3-dicarboxylic acid (1S,3R-ACPD) in hippocampal interneurons of stratum oriens-alveus (OA) with simultaneous whole cell current-clamp...

متن کاملRegulation of the activity of hippocampal stratum oriens interneurons by alpha7 nicotinic acetylcholine receptors.
GABAergic interneurons have been shown to be a major target of cholinergic inputs to the hippocampus. Because these interneurons project to pyramidal neurons as well as other interneurons, activation of the cholinergic system is likely to produce a complex modulation of local inhibitory activity. To better understand the role of post-synaptic alpha7 nicotinic acetylcholine receptors in the hipp...
متن کاملTASK-like conductances are present within hippocampal CA1 stratum oriens interneuron subpopulations.
TASK-1 (KCNK3) and TASK-3 (KCNK9) are members of the two-pore domain potassium channel family and form either homomeric or heteromeric open-rectifier (leak) channels. Recent evidence suggests that these channels contribute to the resting potential and input resistance in several neuron types, including hippocampal CA1 pyramidal cells. However, the evidence for TWIK-related acid-sensitive potass...
