New evidence indicates that increased, rather than decreased, -aminobutyric acid (GABA)ergic inhibition characterizes typical absence seizures. In particular, enhanced tonic GABAA inhibition, resulting from a malfunction of the astrocytic GABA transporter GAT-1, occurs in thalamocortical neurons of all well-established pharmacologic and genetic models. Interestingly, GABAB receptors positively modulate this tonic current.
