Making the right connections

Researchers at VIB and KU Leuven have uncovered a new molecular interaction that governs the formation of specific functional connections between two types of neurons. It gives an important clue as to how unique interactions give shape to precisely organized neuronal networks in the brain. Pyramidal neurons are named after their cell body, which is […]

Why Doesn't Your Vision 'Go Dark' When You Blink?

There's a saying that goes, "Blink and you'll miss it." But generally, we don't miss a thing when we blink; in fact, we don't even notice when we're doing it. Indeed, even though adults blink about 15 times per minute, on average, our vision appears seamless and uninterrupted. But how does that work, exactly? Experts […]

Nerve cells in the human brain can ‘count’

How do we know if we’re looking at three apples or four? Researchers at the Universities of Bonn and Tübingen are now one step closer to answering this question. They were able to demonstrate that some brain cells fire mainly for quantities of three, others for quantities of four and others for other quantities. A […]

Effects of deep brain stimulation in patients with Parkinson’s disease: Improved effects on motor function and fewer side effects possible

Researchers from Charité — Universitätsmedizin Berlin have studied motor and cognitive effects of deep brain stimulation in patients with Parkinson’s disease. Their results show that the adverse cognitive effects of deep brain stimulation are linked to a different neural pathway than that responsible for the treatment’s desired motor effects. This finding will help optimize treatments […]

Traumatic brain injury recovery via petri dish: Synchronized brain-like activity created, recorded and influenced by electrical stimulation

Researchers in the University of Georgia’s Regenerative Bioscience Center have succeeded in reproducing the effects of traumatic brain injury and stimulating recovery in neuron cells grown in a petri dish. This makes them the first known scientific team in the country to do so using stem cell-derived neurons. The procedure, detailed in a new paper […]

How people use, and lose, preexisting biases to make decisions

From love and politics to health and finances, humans can sometimes make decisions that appear irrational, or dictated by an existing bias or belief. But a new study from Columbia University neuroscientists uncovers a surprisingly rational feature of the human brain: A previously held bias can be set aside so that the brain can apply […]

How the brain biases beliefs: Proposed neural circuit may underlie motivation to cling to desirable notions about the future

People’s motivation to cling to desirable notions about future outlooks results from interactions between prefrontal cortex regions, according to a human neuroimaging study published in JNeurosci. Bojana Kuzmanovic and colleagues uncovered circuits in the brain that support belief updating by asking participants to estimate their own and a peer’s likelihood of experiencing an adverse life […]
