A CASE OF RETRO-ANTEROGRADE AMNESIA FOLLOWING GAS POISONING

Postoperative anterograde amnesia.

The problems of defining and estimating preand postoperative amnesia are discussed. The extent of postoperative (anterograde) amnesia in patients receiving pre-operative medication (consisting of atropine, pethidine and pentobarbitone) followed by general anaesthesia (consisting of thiopentone, halothane and nitrous oxide) was ascertained. Two control groups were employed; one received spinal a...

Activation of existing memories in anterograde amnesia.

Two principal arguments against a consolidation-block formulation of anterograde amnesia are the existence of pnor-list intrusion errors and the facilitating effect of cued recall Both of these findings can be explained if one assumes an additional process trace activation of already existing memories. This consolidation-block plus trace-activation view predicts that in densely amnesic patients...

Ketamine induces anterograde and retrograde amnesia in rats

Introduction: The N-methyl-D-aspartate (NMDA) receptors, which have been implicated in memory formation, could be noncompetitively blocked by ketamine. The present study examines the short term effect of ketamine on induction of anterograde and retrograde amnesia in male rats using Morris water maze (MWM). Methods: Male N-MRI rats were randomly divided into nine experimental groups. MWM stud...
