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”

Mice run for fun on wheels out in the wild.

By James Gorman If an exercise wheel sits in a forest, will mice run on it? Every once in a while, science asks a simple question and gets a straightforward answer. In this case, yes, they will. And not only mice, but also rats, shrews, frogs and slugs. True, the frogs did not exactly run,Continue reading “Mice run for fun on wheels out in the wild.”

‘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”

Brain implants: Restoring memory with a microchip

William Gibson’s popular science fiction tale “Johnny Mnemonic” foresaw sensitive information being carried by microchips in the brain by 2021. A team of American neuroscientists could be making this fantasy world a reality. Their motivation is different but the outcome would be somewhat similar. Hailed as one of 2013’s top ten technological breakthroughs by MIT,Continue reading “Brain implants: Restoring memory with a microchip”

Flip of a single molecular switch makes an old brain young

The flip of a single molecular switch helps create the mature neuronal connections that allow the brain to bridge the gap between adolescent impressionability and adult stability. Now Yale School of Medicine researchers have reversed the process, recreating a youthful brain that facilitated both learning and healing in the adult mouse. Scientists have long knownContinue reading “Flip of a single molecular switch makes an old brain young”

The brain’s natural valium

Hitting the wall in the middle of a busy work day is nothing unusual, and a caffeine jolt is all it takes to snap most of us back into action. But people with certain sleep disorders battle a powerful urge to doze throughout the day, even after sleeping 10 hours or more at night. ForContinue reading “The brain’s natural valium”

Musicians’ Brains Synchronize During Duets

The brain waves of two musicians synchronize when they are performing duet, a new study found, suggesting that there’s a neural blueprint for coordinating actions with others. A team of scientists at the Max Planck Institute for Human Development in Berlin used electrodes to record the brain waves of 16 pairs of guitarists while theyContinue reading “Musicians’ Brains Synchronize During Duets”
