3.1.1 GHB-induced seizure model
In rhesus monkeys, Low doses of GHB (100–200 mg/kg) caused a
low-voltage slowing of the EEG and tiredness. An ongoing activity with
2-3 Hz high-voltage slow waves was visible in the EEG at a dose of 400
mg/kg [36] . Rats have by far the finest documentation of
any animal for GHB effects. In Wistar rats, systemic treatment of GHB
(25–100 mg/kg) increased slow-wave sleep, which continued for up to 4
hours. Instead, higher doses (200 mg/kg) were reported to elicit two
distinct forms of activity in Wistar rats, which were distinguished from
one another both behaviorally and EEG [37] . Initially, the
EEG showed occasional bursts or brief (5-8 seconds) episodes of
hypersynchronous 5- 6 Hz “spikes and waves.”
Advantages: Humans, nonhuman primates like rhesus monkeys,
and rodents like rats and mice have all been used in scientific
studies. Cross-species comparisons can highlight similarities in
pathophysiology
Disadvantages: Seizures brought on by GHB might not entirely
reflect the complexity and features of seizures experienced by people
with epilepsy.
3.1.2: PTZ-induced seizure model: Wistar rats weighing around
200 – 250 g are taken for the seizure model. They were injected with 20
mg/kg of PTZ intraperitoneally. SWD characterizes the absence of seizure
activity in rats as in humans [29] .
