Cannabis Reverses Aging Processes in the Brain

Memory performance decreases with increasing age. Cannabis can reverse these ageing processes in the brain. This was shown in mice by scientists at the University of Bonn with their colleagues at The Hebrew University of Jerusalem (Israel). Old animals were able to regress to the state of two-month-old mice with a prolonged low-dose treatment with a cannabis active ingredient. This opens up new options, for instance, when it comes to treating dementia.

Babies' Slow Brain Waves Could Predict Problems

The brain waves of healthy newborns – which appear more abnormal than those of severe stroke victims – could be used to accurately predict which babies will have neurodevelopmental disorders.

No Evidence That Brain Stimulation Technique Boosts Cognitive Training/

Transcranial direct-current stimulation (tDCS)--a non-invasive technique for applying electric current to areas of the brain--may be growing in popularity, but new research suggests that it probably does not add any meaningful benefit to cognitive training.

Resetting Balance in Reward Center May Help Treat Alcohol Addiction

The human brain functions on a delicate balance of reinforcing positive behaviors and suppressing negative ones, which takes place in the dorsal striatum, a brain region critical for goal-directed behavior and implicated in drug and alcohol addiction.

Cannabis Derivative Cannabidiol Reduces Seizures in Severe Epilepsy Disorder

After years of anecdotal claims about its benefits, the cannabis derivative cannabidiol reduced seizure frequency by 39 percent for patients with Dravet syndrome - a rare, severe form of epilepsy - in the first large-scale randomized clinical trial for the compound.

From Blue and Black Dresses to Turbine Blades: The Science of 'Fake Fake' Photos

Whether it's a blue and black dress - or white and gold depending on your take - or a pair of legs streaked with white paint, eagle-eyed viewers are always keen to debate a visual illusion when these puzzling images appear online.

From Context to Cortex : Discovering Social Neurons

Understanding how the brain functions within a social context is a major challenge facing neuroscientists. Through their unique multidisciplinary collaboration, a primate neurophysiologist and an experimental social psychologist have now discovered two new classes of neurons in the prefrontal cortex: social and asocial neurons.

Learning to Read in Your 30s Profoundly Transforms the Brain

Reading is such a new ability in human evolutionary history that the existence of a 'reading area' could not be specified in our genes. A kind of recycling process has to take place in the brain while learning to read: Areas evolved for the recognition of complex objects, such as faces, become engaged in translating letters into language. Some regions of our visual system thereby turn into interfaces between the visual and language systems.
