Two distinct brain regions have independent influence on decision-making

Often when we make a decision, we calculate its “expected value,” by multiplying the value of something (how much we want or need it) with the probability that we might be able to obtain it, a concept first introduced by 17th-century mathematician Blaise Pascal. Now, research conducted at the Icahn School of Medicine at Mount [...]

Study finds hormone therapy improves sleep quality for recently menopausal women

For many women, the side effects of menopause don’t call it a day when they do. Between 40 and 60 percent of women in perimenopause and early menopause face issues with sleep because of this physical change. The majority also report hot flashes and night sweats, which can be disruptive to falling and staying asleep. [...]

Inattentive kids show worse grades in later life

Researchers studied children with and without attention deficit hyperactivity disorder (ADHD), and found that inattentiveness was linked to worse academic performance up to 10 years later, regardless of ADHD, even when they accounted for the children’s intellectual ability. Although grades aren’t everything, academic achievement is clearly an important factor in later career success and financial [...]

‘Seeing’ robot learns tricky technique for studying brain cells in mammals

Whole-cell patch clamp electrophysiology, or whole-cell recording (WCR), is the gold-standard technique for studying the behaviour of brain cells called neurons under different brain states such as stress or learning. The procedure has been used in mammals since it was developed in the 1970s. It helps scientists to understand brain function and brain disorders such [...]

Bowel cancer study reveals impact of mutations on protein networks

For the first time, scientists have completed a detailed study of many of the proteins in bowel cancer cells. Scientists from the Wellcome Trust Sanger Institute investigated the role proteins play in predicting how common mutations affect proteins in the cancer cells and also whether such proteins are important in predicting the cancer’s response to [...]
