The way we breathe may affect how well our memories are consolidated (i.e. reinforced and stabilised). If we breathe through the nose rather than the mouth after trying to learn a set of smells, we remember them better, researchers at Karolinska Institutet in Sweden report in The Journal of Neuroscience. Research into how breathing affects […]
Pioneering research has given a fascinating fresh insight into how animal nervous systems evolved from simple structures to become the complex network transmitting signals between different parts of the body. The new study used simple multicellular organisms called Placozoa to reveal the beginnings of the nervous systems found in more complex animals. The international research […]
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 […]
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 […]
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 […]
How we feel about our own material wellbeing and status in society is largely determined by our evaluation of others. However, the neurological underpinnings to how we monitor the complex social environment under conditions of limited access to resources and whether we feel happy or disappointed with our lot have remained unclear. In a new […]
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 […]
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 […]
Certain brain cancers are associated with low numbers of immune system T-cells circulating in the peripheral blood. Low T-cell numbers can be a side-effect of cancer treatment. But it now appears that there is more to the story of these missing T-cells. Researchers from multiple institutions, including Osaka University, have now revealed how brain cancers […]
A new study provides fresh evidence that the decline in the capacity of brain cells to change, called “plasticity,” rather than a decline in total cell number may underlie some of the sensory and cognitive declines associated with normal brain aging. Scientists at MIT’s Picower Institute for Learning and memory show that inhibitory interneurons in […]
