A sustained state of vigilance will generate a different type of memory than a momentary startle, and these differences are linked to distinct signaling molecules in the brains of mice. Researchers at the RIKEN Center for Brain Science (CBS) have visualized these dynamics in the living mouse brain for the first time, observing fast and… Read more

The three proteins Teneurin, Latrophilin and FLRT hold together and bring neighboring neurons into close contact, enabling the formation of synapses and the exchange of information between the cells. In the early phase of brain development, however, the interaction of the same proteins leads to the repulsion of migrating nerve cells, as researchers from the… Read more

Previous research into brain damage caused by the Zika virus shows the virus’s preference for a particular neural cell: the astrocyte. However, few studies have sought to identify the infection effects on these cells, as well as their association with developmental alterations, including brain malformations and microcephaly. Now, new work explores the virus’s consequences on… Read more

The molecules of the neurotransmitter glutamate released when a signal is transferred between two brain cells has been counted, for the first time, by researchers at Chalmers University of Technology and Gothenburg University in Swedenby. With a novel analysis method, they demonstrated that the brain regulates its signals using glutamate in more ways than previously… Read more

Having a larger hippocampus doesn’t always reliably predict learning and memory abilities in older adults, research suggests. It’s normal for the hippocampus — a curved, seahorse-shaped structure embedded deep in the brain — to shrink as we age, but it’s much more pronounced in people with mild cognitive impairment or Alzheimer’s disease. Scientists long believed… Read more
