Abstract:
Genetic variations and developmental insults independently have been proposed to underlie aberrant gamma activity in schizophrenia. We investigated differences in spectral power in gamma (30-100Hz) frequency in patients with familial and sporadic schizophrenia. Subjects underwent resting-awake EEG recording on 192 channels. The two patient subgroups did not significantly differ in any of the gamma bands and regions. We conclude that complex gene-environment interactions are responsible for the limited power of familial-sporadic distinction in schizophrenia.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
