Humans think using their brain's navigation system: Christian Doeller and his team combine individual threads of evidence to form a theory of human thinking.
Our ability to selectively forget distracting memories is shared with other mammals, suggests new research from the University of Cambridge. The discovery that rats and humans share a common active forgetting ability -- and in similar brain regions -- suggests that the capacity to forget plays a vital role in adapting mammalian species to their environments, and that its evolution may date back at least to the time of our common ancestor.
Adolescent marijuana use may alter how neurons function in brain areas engaged in decision-making, planning and self-control, according to researchers at the University of Illinois at Chicago.
Research released today underscores both the dangers and the therapeutic promise of marijuana, revealing different effects across the lifespan. Marijuana exposure in the womb or during adolescence may disrupt learning and memory, damage communication between brain regions, and disturb levels of key neurotransmitters and metabolites in the brain. In Alzheimer's disease, however, compounds found in marijuana, such as the psychoactive compound delta-9-tetrahydrocannabinol (THC), may improve memory and mitigate some of the disease's symptoms.
Improved communication skills may be linked to increased connectivity between auditory and motor regions of the brain, researchers at Université de Montreal and McGill University find.
Researchers at Emory and the Chinese Academy of Sciences analyze mice partially lacking MIR-137.
Some conversations are forgotten as soon as they are over, while other exchanges may leave lasting imprints. Researchers want to understand why and how listeners remember some spoken utterances more clearly than others. They're specifically looking at ways in which clarity of speaking style can affect memory. They will describe their work at the Acoustical Society of America's 176th Meeting, Nov. 5-9.
The views expressed by political party leaders can change how individual voters feel about an issue, according to findings from a longitudinal study of voters in New Zealand. The findings are published in Psychological Science, a journal of the Association for Psychological Science.
Our brains are able to store memories of very similar events as distinct memories. This, for example, allows you to find your car even though you parked it in a different spot the previous day, and even though the two memories are very similar. Researchers at IST Austria are deciphering how the brain computes this pattern separation in a brain region called the dentate gyrus. Results of their work are published today in Nature Communications.
Children who create imaginary parallel worlds known as paracosms, alone or with friends, are more found more commonly than previously believed, according to a study led by a University of Oregon psychologist.
