A 2 × 2 factorial design was used to investigate the effects of electroconvulsive shock (ECS) and pseudo-ECS (PECS) on a passive avoidance response learned under 2 intensities of footshock (FS). There were no differential effects during acquisition, however, ECS and 0.3-ma. groups extinguished faster than PECS and 2.0-ma. groups.

Supplementary Report

A previous study showed that electroconvulsive shock (ECS) does not interact with foot shock intensity; however, ECS-produced retrograde amnesia was not evident on the first test trial following training. The present study decreased the learning trial-ECS interval to 2 sec. and retrograde amnesia was observed but ECS, again, did not interact with foot shock intensity (0.5 and 3.0 ma.).

The administration of electroconvulsive shock after foot shock in a passive avoidance learning situation produced retrograde amnesia if electroconvulsive shock occurred within 20 sec. of the foot shock. If the time interval between foot shock and electroconvulsive shock was 20 sec. or longer, retrograde amnesia was not observed. No behavioral differences were observed between two inbred strains of mice, the DBA/2J and the C57BL/6J.

Original Treatment

Three groups of Ss were given passive avoidance response (PAR) training in a step-down box. Group NT was given neither foot shock (FS) not electroconvulsive shock (ECS) upon stepping down, Group FS received FS but no ECS, and Group FS-ECS received FS followed by ECS. Subgroups from each of these treatment groups were tested for retention 24, 48, or 72 hr. after original treatment. PAR learning was found in all of the FS groups and in the 48-hr. FS-ECS group. There was an apparent increment in the PAR at 48 hr. for both FS and FS-ECS groups. Retrograde amnesia was apparent in the 24- and 72-hr. FS-ECS groups but was reduced in the 48-hr. group.

Higher Sensitivity

A study of the dynamics of preservation of the conditioned reflex of passive avoidance (passive avoidance response) in rats of two lines with different level of excitability of the nervous system was performed: with a high and low thresholds of excitability as normal and after exposure to sodium thiopental semi-lethal dose. It was shown that a long preservation of the memorable trace under standard conditions and a higher sensitivity to the sodium thiopental action manifest in rats with a high excitability threshold in comparison with low-excitable line of rats.
