Oxiracetam increases the release of endogenous glutamate from depolarized rat hippocampal slices.

Nootropics are drugs employed to improve cognitive functions, particularly learning and memory ability, and to prevent their impairment following cerebral damage (Moos et al., 1988). Oxiracetam (4-hydroxy-2-oxopyrrolidinoacetamide) has been reported to enhance learning and memory in normal animals as well as in animals bearing different types of cerebral impairment. Clinical effects of oxiracet...

a-Bungarotoxin-Sensitive Nicotinic Receptors Indirectly Modulate [H]Dopamine Release in Rat Striatal Slices via Glutamate Release

Nicotinic agonists elicit the release of dopamine from striatal synaptosomes by acting on presynaptic nicotinic acetylcholine receptors (nAChRs) on dopamine nerve terminals. Both a3b2* and a4b2 nAChR subtypes (but not a7* nAChRs) have been implicated. Here, we compared nAChR-evoked [H]dopamine release from rat striatal synaptosome and slice preparations by using the nicotinic agonist anatoxin-a...

ATP inhibits glutamate synaptic release by acting at P2Y receptors in pyramidal neurons of hippocampal slices.

It has been proposed that extracellular ATP inhibits synaptic release of glutamate from hippocampal CA1 synapses after its catabolism to adenosine. We investigated the possibility that at least part of this effect is mediated by ATP itself acting on P2Y receptors. ATP and various analogs decreased the amplitude and duration of glutamate-mediated excitatory postsynaptic potentials in all tested ...

Modulation of Basal Glutamatergic Transmission by Nicotinic Acetylcholine Receptors in Rat Hippocampal Slices

Objective(s) Nicotinic acetylcholine receptors (nAChRs) regulate epileptiform activity and produce a sustained pro-epileptogenic action within the hippocampal slices. In the present study, we investigated the effect of nAChRs on evoked glutamatergic synaptic transmission in area CA3 and CA1 of rat hippocampal slices to identify possible excitatory circuits through which activation of nAChRs pr...

Cryopreservation of rat hippocampal slices by vitrification.

Although much interest has attended the cryopreservation of immature neurons for subsequent therapeutic intracerebral transplantation, there are no reports on the cryopreservation of organized adult cerebral tissue slices of potential interest for pharmaceutical drug development. We report here the first experiments on cryopreservation of mature rat transverse hippocampal slices. Freezing at 1....
