Temporary anxiety can hamper learning
Temporary anxiety can hamper learning A recent study published in Nature Science of Learning found that temporary anxiety can significantly impact learning and spatial memory. The researchers used a virtual reality game to test participants’ ability to distinguish between safe and dangerous areas, and found that those who learned to do so showed better spatial […]

How does your brain create new memories? Neuroscientists discover ‘rules’ for how neurons encode new information
How does your brain create new memories? Neuroscientists discover ‘rules’ for how neurons encode new information Researchers have identified “rules” for how neurons encode new information in the brain, revealing that different groups of synapses on a neuron follow different learning rules. The traditional Hebbian rule, where neurons that consistently fire together wire together, does […]

Your time in high school affects your Alzheimer’s risk
Your time in high school affects your Alzheimer’s risk A new study reveals that high school contexts, opportunities, and outcomes play a significant role in shaping midlife cognition, even among individuals with the same completed degrees. The quality of one’s high school experience, not just degree attainment, affects brain health decades later, according to lead […]

How does electrical brain stimulation ease post-stroke symptoms?
How does electrical brain stimulation ease post-stroke symptoms? A pilot study investigated the effects of transcranial direct current stimulation (tDCS) on post-stroke patients, particularly those with aphasia, a language disorder resulting from a stroke injury. The study found that participants who received real tDCS showed significantly larger pupil dilation, which could indicate improved attention, but […]

Pupils shed light on the brain during sleep
Pupils shed light on the brain during sleep For the first time, researchers have been able to observe how the pupils react during sleep over a period of several hours. A look under the eyelids showed them that more happens in the brain during sleep than was previously assumed. Our eyes are typically closed when […]
