For a conditioned response to become long-lasting requires brain cells to increase amounts of an insulating material called myelin, which may serve to reinforce and stabilize newly formed neural connections.
Understanding the biological differences that drive distinct symptoms of Alzheimer’s disease could lead to more personalized patient care and potentially therapies targeted to patients’ individual needs.
In a study of rats navigating a simple maze, neuroscientists at UCSF have discovered how the brain may generate such imagined future scenarios. The work provides a new grounding for understanding not only how the brain makes decisions but also how imagination works more broadly, the researchers say.
Scientists have documented the influence of information overload on attention, perception, memory, decision-making, and emotional regulation. But the same technologies contributing to the cognition crisis could help solve it, argues neuroscientist Adam Gazzaley.
