New educational approaches and advances in brain-based research are making it possible to detect dyslexia even in children too young to read. Though it is not a cure, stepping in early with targeted intervention could prevent reading problems from derailing a child’s education.

Research in animals hints at the neurobiology of depression, why antidepressant treatment does not take effect immediately and why some people are more resilient amid stress. It also highlights the importance of using a combination of animal models to study depression.

Thinking about something we want to avoid saying makes us more likely to say it. Blame the brain's prefrontal cortex, home to processes involved in developing plans and carrying them out.

Does consciousness—our awareness that we are perceiving something—arise from a special region in the brain, or from the coherent workings of multiple regions? Analyzing data from electrodes implanted in the brains of epilepsy patients, French researchers suggest the latter.

Signs of Alzheimer’s may be detectable years before symptoms emerge. New brain imaging techniques and other approaches are giving scientists new insight into disease risk and may one day help them start treatment earlier and develop better methods.

A form of visual therapy that employs computer exercises may help restore some vision to patients who lost sight as a result of stroke. Some researchers are skeptical that the patients were truly blind, however.

Experts remain divided on the merits of hormone treatment for menopausal women. New evidence lends support to the idea that timing, genetics and the existence of different estrogen receptors in the brain contribute to the effects of estrogen on memory, mood and cognition.

Past studies of psychostimulant drugs taken for attention-deficit/hyperactivity disorder have shown a slowing of cortical growth, but new imaging research reveals that the drugs may normalize development. Researchers still urge caution, however.

Elevated blood glucose levels negatively affect a subregion of the hippocampus responsible for forming memories, according to new research. The finding may help explain memory impairment as we age and in people with diabetes. Other studies are looking at whether medications help absorb glucose and improve memory.

Testosterone levels before birth affect financial traders’ success, perhaps by enhancing risk taking, a recent study suggests. The clue lies in the length of traders’ ring fingers relative to their index fingers—longer ring fingers indicate greater testosterone exposure in the womb, and traders with this characteristic made more money than others, on average.

Addiction doesn’t just affect people’s pleasure centers; it may also short-circuit brain areas responsible for self-awareness and for restraining impulsive behavior, suggests new research looking into why the disease is so difficult to treat.

New studies suggest that the brain engages in “probabilistic reasoning” similar to the method the Allies used to crack Nazi Germany’s codes—but that sleep deprivation compromises our ability to assess the future.

Neuroscience-based methods of lie detection already may have passed the test of public acceptance, but whether they work is still an open question in the scientific community. The growing disparity between public and scientific understanding of “forensic neuroscience” was one of several pressing issues that brought nearly 200 people to Washington, D.C., for the annual meeting of the Neuroethics Society.

Scientists have found that long-term love appears to leave a distinct signature in the brain and that a specific gene affects courtship behavior—at least in mice.

Humans need only a few milliseconds to judge a facial expression and decide whether to trust another person or not. Recent studies shed light on how we make that judgment, as well how context can influence our response.

While some people seem to be endowed with a special ability to remember numbers, researchers suggest that we all have an innate “numbers sense”—and that memorization skills may boil down to repetition.
