Rats of the control
group took less time for jumping in to dark chamber (where
electric shock was provided on day 1) as compared to rats
treated with BG 400 and BG 800 and piracetam 500. Rats
treated with both dose of BG and piracetam spent more time
in illuminated chamber than the control group. This showed
that rats of the control group have less memorizing capacity
i.e. they forget electric shock, which was given in dark chamber
just after jumping in to dark chamber and jumped in to dark
chamber earlier than both dose of BG and piracetam 500
treated rats. This showed that step through latency of BG
400, BG 800 and piracetam 500 treated rats was significantly
increased when compared with control group on day 2 and 9
as well as to the same group on day 1. Increase in step through
latency may be indicative of increase in memory. Thus BG and
piracetam increases learning and memory. BG and piracetam
treated rats took significantly fewer trials, shocked trials and
total time to re‑learn the task as compared to control group.
In this test, most of the rats treated with BG jumped into safe
compartment before providing electric shock, but most of the
rats of the control group jumped into safe compartment after
exposure to electric shock. Thus total shock trial in BG and
piracetam treated rat was less as compared to control group.
In the same way total time and total trial required by BG
and piracetam treated rats was less as compared to rats of the control group.
