||Figure 13. The effect of EPA (12 mgs) infused
into the right jugular vein of a rat on the electrical threshold for the
induction of seizure activity. The seizure threshold increased rapidly
following the EPA infusion and was still elevated the next morning. The
lower curve with black dots shows the threshold increase for the earliest
sign of hyperactivity (TLS) manifested by twitching of the ratís whiskers.
The upper curve with open circles shows the threshold for gross seizure
activity of the rat (TGS).
