An Issue in 2 Brain Areas Can Trigger Petit Mal Seizures

cerebral cortex and the thalamus

In August 2011, researchers working at the Stanford University School of Medicine have been able to identify a defect in the brain which triggers petit mal seizures (also known as absence seizures).

The researchers showed that if there is a problem or a defect in the communication between cerebral cortex and the thalamus (two parts of the brain) then there is a loss of consciousness and a brain state which looks very much like the petit mal seizure state. (The experiment was done on mice)

This discovery, although not revolutionary by itself, makes a great progress step towards understanding the true origins and workings of the seizures.

  1. Wow this is absolutely amaizing to pin point the source of seizures to such communication problem within the brain, thanks for sharing.
    I hope they also research how to fix that.

  2. very interesting research on the brain connection and seizures
