This study sought to compare the detailed electrophysiological characterization of GABAergic neurotransmission in pyramidal neurons in the SOZ and non-SOZ inside the EZ of patients with FCD with non-epileptic temporal neocortex and to correlate these features with the patterns of NKCC1 and KCC2. The gene discussed is SLC12A2; the disease is fleck corneal dystrophy.
