Uncovering the Epilepsy Brain Circuit: A Breakthrough Discovery

Researchers have identified a shared brain circuit that may link diverse lesion locations causing epilepsy. By analyzing data from over 1,500 patients with brain lesions, the study suggests that the disrupted connections within the brain circuit, rather than the lesion locations themselves, are crucial in the development of epilepsy. This discovery could lead to improved strategies for predicting epilepsy risk after brain damage and more effective brain stimulation treatments. The identified brain circuit is located deep within the basal ganglia and cerebellum regions of the brain, known to control seizures in animal models of epilepsy.

Unveiling the Mysteries of the Human Brain's Hidden Networks.

Researchers have identified specific brain network connections associated with anosognosia, a condition where patients are unaware of their neurological or psychiatric deficits. Using a technique called lesion network mapping, they identified separate networks linked to visual and motor anosognosia and a shared network responsible for awareness of these deficits. The shared network converged on the hippocampus and precuneus, both associated with memory. This is the first systematic analysis to highlight the role of the hippocampus in visual anosognosia.
