BR-16A restricts development of electroconvulsive shock-induced retrograde amnesia.
Forty nine adult male Sprague Dawley rats were selected for rapid learning in a T-maze to study the effects of BR-16A, a herbal preparation on ECS-induced retrograde amnesia. Half the rats received 200 mg/kg BR-16A and the other half received vehicle alone. The rats were trained to run into the enclosed chamber of either the left or the right arm on a T-maze; a food pellet served as a reward in...
متن کاملPre-electroconvulsive shock administration of calcium channel blockers reduces retrograde amnesia induced by ECS.
Effect of pre-electroconvulsive shock (ECS) administration of calcium channel blockers (CCBs) like verapamil, diltiazem, nifedipine, nimodipine, flunarizine and cinnarizine on retrograde amnesia induced by ECS was examined using passive avoidance paradigm in rats. The groups (Gr 1-7) of adult, male Wistar rats received true ECS with CCBs (5mg/kg; i.p) or vehicle (10 ml/kg; ip) and other groups ...
متن کاملDifferential assessment of retrograde amnesia produced by Hypothermia following one-trial avoidance conditioning
Two different measures of the retention of avoidance conditioning, frequently used in the investigation of retrograde anmesia (RA), were examined. Rats were given a single training trial on either passive or active avoidance in a conventional black-white discrimination apparatus and step•through latencies were recorded. Task sequence, footshock and hypothermia were experimentally varied across ...
متن کاملRetrograde amnesia after electroconvulsive therapy: a temporary effect?
OBJECTIVE Although electroconvulsive therapy (ECT) is generally considered effective against depression, it remains controversial because of its association with retrograde memory loss. Here, we assessed memory after ECT in circumstances most likely to yield strong retrograde amnesia. METHOD A cohort of patients undergoing ECT for major depression was tested before and after ECT, and again at...
متن کاملEnvironmental control of ECS-produced retrograde amnesia in goldfish.
Environmental control of ECS-produced retrograde amnesia in goldfish. PHYSIOL. BEHAV. The retrograde amnestic effect of ECS can be enhanced by exposing the goldfish to the intertrial environment for 25 mm just prior to administration of the ECS. As the interval between training and the ECS is increased, the amnesm produced by the environment-ECS interaction takes longer to develop. The environm...
