The corticothalamic cortical circuit plays an important role in the pathophysiology of<unk> . Some of the neurons are important in their occurrence. They are *Cortical glutamatergic neurons *Thalamic relay neurons *Neurons of thalamic nucleus reticularis Abnormal oscillatory rhythms develop in the thalamic nucleus reticularis. This causes inhibition of GABAergic neurotransmission and excitation of glutamate neurotransmission. Abnormal oscillatory spikes are produced by the low threshold T-type calcium channel. This explains how inheritance of gene code for T-type calcium channel leads to an<unk> . Antiepileptic drugs such as Gabapentin,Tiagabine and Vigabatrin cause inhibition of GABA results in exacerbation of<unk> s.
