 E-Mail When we recall a memory, we retrieve specific details about it: where, when, with whom. But we often also experience a vivid feeling of remembering the event, sometimes almost reliving it. Memory researchers call these processes objective and subjective memory, respectively. A new study from the Center for Mind and Brain at the University of California, Davis, shows that objective and subjective memory can function independently, involve different parts of the brain, and that people base their decisions on subjective memory -- how they feel about a memory -- more than on its accuracy...

Credit: UPF ften, humans display biases, i.e., unconscious tendencies towards a type of decision. Despite decades of study, we are yet to discover why biases are so persistent in all types of decisions. "Biases can help us make better decisions when we use them correctly in an action that has previously given us great reward. However, in other cases, biases can play against us, such as when we repeat actions in situations when it would be better not to", says Rubén Moreno Bote, coordinator of the UPF Theoretical and Cognitive Neuroscience Laboratory. In these cases, decisions are guided by t...

The progressive decline in brain function that can follow traumatic brain injury (TBI) is associated with complement activation, part of the immune system that contributes to inflammation and clears damaged cells. Inhibiting complement even two months after injury reduced brain cell inflammation and reversed mental losses, report researchers at the Medical University of South Carolina in the

New research at Penn shows that a single head injury could lead to dementia later in life. This risk further increases as the number of head injuries sustained by an individual increases. The findings also suggest stronger associations of head injury with risk of dementia among women compared to among men and among white as compared to among Black populations.

 E-Mail People over 65 shouldn't take three or more medicines that act on their brain and nervous system, experts strongly warn, because the drugs can interact and raise the risk of everything from falls to overdoses to memory issues. But a new study finds that 1 in 7 people with dementia who live outside nursing homes are taking at least three of these drugs. Even if they received the drugs to calm some of dementia's more troubling behavioral issues, the researchers say, taking them in combination could accelerate their loss of memory and thinking ability, and raise their chance of injury...
