Personality and mood affect brain response to personal choice

Personality traits and mental health affect how people value personal control in decision making, according to a new study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. Our brain’s reward and motivation systems show higher activity when we feel personal control in a situation and when we receive rewards that we’ve earned, rather than been given […]

Abnormal vision in childhood can affect brain functions

A research team has discovered that abnormal vision in childhood can affect the development of higher-level brain areas responsible for things such as attention. The researchers from the University of Waterloo, University of British Columbia, and the University of Auckland uncovered differences in how the brain processes visual information in patients with various types of […]

Artificial intelligence helps reveal how people process abstract thought: Study of deep neural networks suggests knowledge comes via sensory experience

As artificial intelligence becomes more sophisticated, much of the public attention has focused on how successfully these technologies can compete against humans at chess and other strategy games. A philosopher from the University of Houston has taken a different approach, deconstructing the complex neural networks used in machine learning to shed light on how humans […]

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 […]

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 […]

New sensors track dopamine in the brain for more than year: Tiny probes could be useful for monitoring patients with Parkinson’s and other diseases

Dopamine, a signaling molecule used throughout the brain, plays a major role in regulating our mood, as well as controlling movement. Many disorders, including Parkinson’s disease, depression, and schizophrenia, are linked to dopamine deficiencies. MIT neuroscientists have now devised a way to measure dopamine in the brain for more than a year, which they believe […]

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 […]
