A Seizure Occurs When the Cerebral Cortex Is Hyperexcitable, Caused

A seizure occurs when the cerebral cortex is hyperexcitable, caused by:

A) A decrease in excitatory neurotransmission, an increase in inhibitory neurotransmission, or a disturbance in brain circuitry
B) An increase in excitatory neurotransmission, a decrease in inhibitory neurotransmission, or a disturbance in brain circuitry
C) An increase in excitatory neurotransmission, an increase in inhibitory neurotransmission, or a disturbance in brain circuitry
D) A decrease in excitatory neurotransmission, a decrease in inhibitory neurotransmission, or a disturbance in brain circuitry
