A new study in mice shows a link between the brain’s chemical system and the mice’s belief about how waiting will pay off. The effect of the neuromodulator serotonin on mice’s ability to stay patient when waiting for a reward is at the core of the study[1], by Dr. Katsuhiko Miyazaki and Dr. Kayoko Miyazaki… Read more

Human behavior is typically elucidated in terms of unseen entities such as motivation, curiosity, anxiety and confidence. What has been unclear is whether these mental entities are coded by specific neurons in specific areas of the brain. Professor Adam Kepecs at Cold Spring Harbor Laboratory has answered some of these questions in new research. The… Read more

Without hardly noticing, we make countless decisions: to turn left or right on the bus? To wait or to accelerate? To look or to ignore? In the run-up to these decisions the brain evaluates sensory information and only then does it generate a behavior. For the first time, scientists at the Max Planck Institute of… Read more

For both victims of violations as well as witnesses, punishment decisions activate the brain regions responsible for focusing one’s attention, processing information, and responding effectively to social interaction, according to a recent study. Conducted by Oksana Zinchenko, Research Fellow at the Institute of Cognitive Neuroscience, National Research University Higher School of Economics in Moscow, the… Read more

When mice learn to do a new task, their brain activities change over time as they advance from ‘novice’ to ‘expert.’ The wiring of cell circuits and the activities of neurons reflect the changes, new research shows[1]. Using a two-photon imaging microscope and a wealth of genetic tools, researchers found that neural networks become more… Read more
