Domain-Specific Inhibitory Control Training to Improve Children's Learning of Counterintuitive Concepts in Mathematics and Science.

Evidence from cognitive neuroscience suggests that learning counterintuitive concepts in mathematics and science requires inhibitory control (IC). This prevents interference from misleading perceptual cues and naïve theories children have built from their experiences of the world. Here, we (1) investigate associations between IC, counterintuitive reasoning, and academic achievement and (2) evaluate a classroom-based computerised intervention, called Stop & Think, designed to embed IC training within the learning domain (i.

Acamprosate, MK-801, and ifenprodil inhibit neurotoxicity and calcium entry induced by ethanol withdrawal in organotypic slice cultures from neonatal rat hippocampus.

Background: The antirelapse drug acamprosate has previously been reported to inhibit activating effects of polyamines on -methyl-D-aspartic acid receptor (NMDAR) function. Because increased synthesis of polyamines has been suggested as a mechanism for potentiation of NMDAR function during ethanol withdrawal, we evaluated the effects of acamprosate, MK-801, and ifenprodil in a cell culture model of ethanol withdrawal-induced neurotoxicity.

Methods: Organotypic hippocampal cultures from 8-day-old neonatal rats were maintained in vitro for 23 days before experimental use.

Acamprosate has no effect on NMDA-induced toxicity but reduces toxicity induced by spermidine or by changing the medium in organotypic hippocampal slice cultures from rat.

Background: It has been suggested that the antirelapse drug acamprosate can inhibit or potentiate glutamate/NMDA receptor-mediated responses via a polyamine site. Additionally, subchronic exposure to acamprosate increases expression of some NMDA receptor subunits. These effects on NMDA receptors imply that the drug may have neurotoxic or neuroprotective actions under different conditions, and these studies were undertaken to evaluate this possibility in hippocampal neuronal cultures.
