Summary: Researchers have utilized depth electrodes in epilepsy patients to study exogenous attention, the involuntary shift of focus triggered by external stimuli. This unique approach, capturing neural activity across 1,400 brain regions, reveals how attention develops from visual processing to action response, involving a continuum of cortical networks. The […]

Summary: During absence seizures, most neurons showed decreased activity. This, researchers say, explains the decrease in brain function and impaired consciousness during an absence epilepsy seizure.

Temporal lobe epilepsy (TLE) is one of the most common types of epilepsy worldwide. Although symptomatic medications are available, one-third of TLE patients remain unresponsive to current treatment, so new drug targets are critically needed. A research team co-led by a City University of Hong Kong (CityU) neuroscientist recently […]

image: D4 treatment decreases the proliferation and activation of astrocytes in two different brain regions. Pilocarpine was injected into the mice intraperitoneally to induce seizures. Seven days after pilocarpine-induced seizures, the researchers observed a chronic elevation in the number of astrocytes (marked by GFAP staining in red; all cell […]
