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.
