Brain decoder can eavesdrop on your inner voice

Talking to yourself used to be a strictly private pastime. That’s no longer the case – researchers have eavesdropped on our internal monologue for the first time. The achievement is a step towards helping people who cannot physically speak communicate with the outside world. “If you’re reading text in a newspaper or a book, youContinue reading “Brain decoder can eavesdrop on your inner voice”

7 Very Bizarre (and Very Rare) Psychotic Hallucinations

brain The many documented cases of strange delusions and neurological syndromes can offer a window into how bizarre the brain can be. It may seem that hallucinations are random images that appear to some individuals, or that delusions are thoughts that arise without purpose. However, in some cases, a specific brain pathway may create aContinue reading “7 Very Bizarre (and Very Rare) Psychotic Hallucinations”

Brain tumor causes uncontrollable laughter

They say laughter is the best medicine. But what if laughter is the disease? For a 6-year-old girl in Bolivia who suffered from uncontrollable and inappropriate bouts of giggles, laughter was a symptom of a serious brain problem. But doctors initially diagnosed the child with “misbehavior.” “She was considered spoiled, crazy — even devil-possessed,” Dr.Continue reading “Brain tumor causes uncontrollable laughter”

Possible link between cynicism and risk of dementia

Cynics are three times more likely to develop dementia than those who have faith in humanity, a study has shown. Believing that others are motivated by selfishness, or that they lie to get what they want, appears to radically increase the risk of cognitive decline in later life. It could mean that grumpy old menContinue reading “Possible link between cynicism and risk of dementia”

Study Finds Pedophiles’ Brains Wired to Find Children Attractive

Pedophiles’ brains are “abnormally tuned” to find young children attractive, according to a new study published this week. The research, led by Jorge Ponseti at Germany’s University of Kiel, means that it may be possible to diagnose pedophiles in the future before they are able to offend. The findings, published in scientific journal Biology Letters,Continue reading “Study Finds Pedophiles’ Brains Wired to Find Children Attractive”

What I’ve Learned: Sol Snyder

Sol Snyder, Distinguished Service Professor of Neuroscience, Pharmacology and Psychiatry, School of Medicine Growing up, I never had any strong interest in science. I did well in lots of things in high school. I liked reading philosophy and things like that, but being a philosopher is not a fit job for a nice Jewish boy.Continue reading “What I’ve Learned: Sol Snyder”

New blood test to predict who will develop Alzheimer’s disease

In a first-of-its-kind study, researchers have developed a blood test for Alzheimer’s disease that predicts with astonishing accuracy whether a healthy person will develop the disease. Though much work still needs to be done, it is hoped the test will someday be available in doctors’ offices, since the only methods for predicting Alzheimer’s right now,Continue reading “New blood test to predict who will develop Alzheimer’s disease”

‘Jumping Genes’ Linked to Schizophrenia

Roaming bits of DNA that can relocate and proliferate throughout the genome, called “jumping genes,” may contribute to schizophrenia, a new study suggests. These rogue genetic elements pepper the brain tissue of deceased people with the disorder and multiply in response to stressful events, such as infection during pregnancy, which increase the risk of theContinue reading “‘Jumping Genes’ Linked to Schizophrenia”

Electric brain stimulation in a specific area discovered to induce a sense of determination

Doctors in the US have induced feelings of intense determination in two men by stimulating a part of their brains with gentle electric currents. The men were having a routine procedure to locate regions in their brains that caused epileptic seizures when they felt their heart rates rise, a sense of foreboding, and an overwhelmingContinue reading “Electric brain stimulation in a specific area discovered to induce a sense of determination”

New research shows that sleep functions to allow the brain to eliminate toxins that accumulate while we are awake

While the brain sleeps, it clears out harmful toxins, a process that may reduce the risk of Alzheimer’s, researchers say. During sleep, the flow of cerebrospinal fluid in the brain increases dramatically, washing away harmful waste proteins that build up between brain cells during waking hours, a study of mice found. “It’s like a dishwasher,”Continue reading “New research shows that sleep functions to allow the brain to eliminate toxins that accumulate while we are awake”
