New method offers automated way to record electrical activity inside neurons in the living brain
The brain's neurons are coupled together into vast and complex networks called circuits.
University of Iowa biologists have advanced the knowledge of human neurodevelopmental disorders by finding that a lack of a particular group of cell adhesion molecules in the cerebral cortex—the outermost layer of the brain where language, thought and other higher functions take place —disrupts the formation of neural circuitry.
Studying a mouse model of Alzheimer's disease, neuroscientists at the Technische Universitaet Muenchen have observed correlations between increases in both soluble and plaque-forming beta-amyloid – a protein implicated in the disease process – and dysfunctional developments on several levels: individual cortical neurons, neuronal circuits, sensory cognition, and behavior.
