The present study investigated developmental changes in epileptiform activity in rat neocortical slices from four age groups (postnatal days P4--7, P13--16, P23--26, P41--47) due to four pharmacological conditions (4-aminopyridine, low magnesium, picrotoxin, CGP-35348) that differentially modulate glutamate and GABA systems.

Here we show that absence of NKCC1 in P9-P13 CA3 pyramidal neurons, through genetic manipulation or through bumetanide inhibition, results in a significant increase in cell excitability.
Furthermore, the pro-convulsant agent 4-aminopyridine induces seizure-like events in NKCC1-null mice but not in wild-type mice.

A transient decrease (P13-14) and then increase (P15-16) in seizure susceptibility were followed by a tendency to periodicity and focalization.
PURPOSE: The functional significance of gap-junction (GJ) channels in seizure susceptibility and induction and maintenance of seizures in the developing rat brain was investigated on the 4-aminopyridine (4-AP) in vivo epilepsy model.

Spontaneous glycinergic IPSCs were very rare but direct presynaptic depolarization by superfusion with elevated potassium concentration or application of 4-aminopyridine consistently evoked strychnine sensitive IPSCs.
