Experiencing a frightening incident is likely something you will always remember. Why does it remain with you when other kinds of events become increasingly hard to remember with time? A mechanism for the formation of fear memories in the amygdala, the emotional center of the brains, has been identified by a team of neuroscientists from […]

Better learning and longer memories RIKEN neuroscientists have identified an intriguing system for how neuronal activity in mice is dynamically tuned (with signaling at some synapses increasing, while other synapses go silent) in order to stimulate the process of learning and memory development. This discovery offers new insights into the function of brain cells called

While sleeping, the whole brain flow through long, slow waves of electrical activity, like waves on a calm ocean. Scientists call that state of consciousness “slow wave sleep.” Awakening alters the pattern of electrical activity into something that resembles random noise. Yet Cold Spring Harbor Laboratory (CSHL) Assistant Professor Tatiana Engel, Postdoctoral Fellow Yianling Shi,

Humans are inching closer to understanding exactly how the brain codes visual information. Scientists have now established a technique that maps time-varying brain responses to images to expose just how the brain processes visual information. Colgate University Neuroscience Teacher Bruce C. Hansen worked together with Michelle R. Greene (Bates College), and also David J. Field

Scientists from Zurich have created a portable, energy-efficient gadget made from synthetic neurons that can decode brainwaves. The chip uses information recorded from the brainwaves of epilepsy patients to determine which regions of the brain cause epileptic seizures. This opens brand-new perspectives for treatment. Current neural network algorithms produce excellent results that help address an

A set of brain signals known to assist memories form may additionally influence blood glucose levels, finds brand-new research in rats. Researchers at NYU Grossman College of Medicine discovered that a strange signaling pattern in the brain area called the hippocampus, connected by previous studies to memory development, likewise affects the metabolic process, the procedure

According to a study published June 20 in Science, scientists discovered two types of glial cells in the brains of adult mice – an astrocyte and an oligodendrocyte progenitor cell – after pushing neural stem cells to rise from dormancy. The results indicate new roles for glial cells, notorious for offering support to neurons. They also

The neurotransmitters GABA and glutamate have complementary functions – GABA inhibits neurons, while glutamate makes them extra active. Published on July 22nd, 2021, in PLOS Biology, scientists led by Roi Cohen Kadosh and George Zacharopoulos from the University of Oxford revealed that degrees of these two neurotransmitters in the intraparietal sulcus of the brain could
