Temporal lobe epilepsy (TLE) is believed to disrupt resting state functional connectivity in the brain. To explore this association in more depth, investigators used group independent component analysis (ICA) to identify the brain’s default mode network (DMN). The DMN has been linked to episodic memory, which does not function normally in patients with TLE. The researchers found functional connectivity instability over time among patients with left and right sided TLE, when compared with healthy controls. The instability within the DMN was most consistently detected within the precuneus region of the brain.
