Tweaked CRISPR in neurons gives scientists new power to probe brain diseases

A team of scientists at UC San Francisco and the National Institutes of Health have achieved another CRISPR first, one which may fundamentally alter the way scientists study brain diseases. In a paper published August 15 in the journal Neuron, the researchers describe a technique that uses a special version of CRISPR developed at UCSF to systematically alter the activity […]

Virtual treasure hunt shows brain maps time sequence of memories

People have little difficulty remembering the chronology of events, determining how much time passed between two events, and which one occurred first. Apparently, memories of events in the brain are linked when they occur closely together. Using an experiment that combines virtual reality and brain scan technology, Jacob Bellmund and Christian Doeller from the Max Planck Institute for Human Cognitive […]

Best supplements: Two of the best supplements for boosting the brain’s function

Just as athletes take supplements to enhance their physical performance, some people hope to sharpen their wits, memory and stave off diseases with brain boosters. Doctor Ray Swahilian said: “The best supplements for the brain could mean several things. It could mean herbs or nutrients that enhance clarity of thinking, alertness, focus, concentration, memory, and even mood. Most commonly, people […]

Student’s headaches from ‘exam stress’ caused by a BRAIN TUMOUR

Student whose crippling headaches were dismissed as ‘exam stress’ discovers she has a golf ball-sized BRAIN TUMOUR during an eye test at Vision Express Rhiannan Harris had just graduated from university when symptoms appeared She never imagined regular headaches and blurred vision were due to a tumour Opticians referred her to hospital during a check-up in July 2018 Doctors believed […]

Neuroscientists find brain activity patterns that encode our beliefs

For decades, research has shown that our perception of the world is influenced by our expectations. These expectations, also called “prior beliefs,” help us make sense of what we are perceiving in the present, based on similar past experiences. Consider, for instance, how a shadow on a patient’s X-ray image, easily missed by a less experienced intern, jumps out at […]

Important results for brain machine interfaces

Data from Mental Work project, conducted as an experimental artwork at EPFL’s Artlab, indicates that BMI is robust and accessible to the general public, spurring new research collaborations in Switzerland on user experience. Brain-machine interfaces are rarely found outside of medical clinics, where the disabled receive hours or days of training in order to operate wheelchairs with their minds. Now […]

‘It’s Gigantic’: A New Way to Gauge the Chances for Unresponsive Patients

Doctors have known for years that some patients who become unresponsive after a severe brain injury nonetheless retain a “covert consciousness,” a degree of cognitive function that is important to recovery but is not detectable by standard bedside exams. As a result, a profound uncertainty often haunts the wrenching decisions that families must make when an unresponsive loved one needs […]

Pigs help scientists understand human brain

For the first time, researchers in the University of Georgia’s Regenerative Bioscience Center have used an imaging method normally reserved for humans to analyze brain activity in live agricultural swine models, and they have discovered that pig brains are even better platforms than previously thought for the study of human neurological conditions such as Alzheimer’s and Parkinson’s. One immediate potential […]

Reaching and grasping: Learning fine motor coordination changes the brain

Reaching for and grasping objects brings about changes in the connections of a certain neuronal population in the red nucleus, a region of the midbrain, now reported by researchers at the University of Basel’s Biozentrum. They have also shown how fine motor tasks promote plastic reorganization of this brain region. The results of the study have been published in Nature […]
