How Your Brain Detects Patterns without Conscious Thought
The human brain is constantly picking up patterns in everyday experiences — and can do so without conscious thought, finds a study of neuronal activity in people who had electrodes implanted in their brain tissue for medical reasons. The study shows that neurons in key brain regions combine information on what occurs and when, allowing the brain to pick out the patterns in events as they unfold over time. That helps the brain to predict coming events, the authors say. The work was published today in Nature. “The brain does a lot of things that we are not consciously aware of,” says Edvard Moser, a neuroscientist at the Norwegian University of Science and Technology in Trondheim.

Memory Loss Isn’t the Only Sign of Dementia
... In a study published last year, researchers found that people with dementia experienced slight drops in extroversion, agreeableness and conscientiousness before they showed any signs of cognitive impairment. Those personality changes accelerated as more dementia symptoms emerged, said Angelina Sutin, a professor of behavioral sciences and social medicine at Florida State University, who led the study. While the research was conducted using a standardized personality test, there are a few changes in everyday behavior that you can watch out for. A decrease in extroversion, for example, may look like a person becoming more withdrawn, or a narrowing of their social circle.
