Voices in the Brain: Disruption of the Default Network Linked to Hallucinations

Hearing voices that are not there was once thought to be a core symptom of schizophrenia and signify severe mental illness. It has been increasingly acknowledged that people with no other symptoms of schizophrenia or psychosis do hear voices [1]. There are several theories about what causes these auditory hallucinations. For example, there is good evidence that hearing voices can be linked to trauma [2]. Attempting to understand the phenomenon is not only scientifically interesting but also relates to how society views people with these experiences and if and how they may be treated. A search for how these experiences are associated with brain function is ongoing. New research published in the journal Human Brain Mapping suggests that the predisposition to hearing voices may relate to abnormal functioning of the brain whilst at rest [3].

When You Eat May Affect Weight Gain As Much As What You Eat

If there is one thing that the sugar free, low carb, low fat, and gluten free dieting trends of the past few decades have taught us, it’s this: a calorie is a calorie is a calorie. Right? Wrong! Whereas the source of the calories you consume might not have much bearing on the amount of weight you gain, when you consume them very well might. Research in both mice and humans demonstrates that eating whenever one pleases (mice) or later in the day (humans) causes significantly more weight gain than consuming the same diet in a time restricted manner, in keeping with the cyclical nature of the body’s energy metabolism.

Older Brains Get Too Full for New Information

According to new research, learning becomes more difficult as we get older because our brains get too full for new information. This may be due, in part, to finding that with advanced age we get less sleep during the stage in which we don’t dream. Both studies are reported in the prestigious Nature family of journals.
