A research team has used neuroimaging techniques to investigate how being in a romantic relationship produces alterations in the architecture of the brain. They found that being in love is associated with increased connectivity between regions of the brain associated with reward, motivation, emotion regulation, and social cognition.
Research from McGill University reveals that the brain’s motor network helps people remember and recognize music that they have performed in the past better than music they have only heard.
The human brain can select relevant objects from a flood of information and edit out what is irrelevant. It also knows which parts belong to a whole. If, for example, we direct our attention to the doors of a house, the brain will preferentially process its windows, but not the neighbouring houses. Psychologists have now discovered that this also happens when parts of the objects are merely maintained in our memory.
Researchers have found that teens who smoked marijuana daily for several years have an abnormally shaped hippocampus and do poorly on tasks involving long-term memory.
A new study has shown how intentional recall is beyond a simple reawakening of a memory; and actually leads us to forget other competing experiences that interfere with retrieval.
Researchers have identified key cells within the brain that are critical for determining circadian rhythms, the 24-hour processes that control sleep and wake cycles, as well as other important body functions such as hormone production, metabolism, and blood pressure
New York University researchers have devised a computer model to explain how a neural circuit learns to classify sensory stimuli into discrete categories, such as “car vs. motorcycle.” Their findings, which appear in the journal Nature Communications, shed new light on the brain processes underpinning judgments we make on a daily basis.
Queensland scientists have found that non-invasive ultrasound technology can be used to treat Alzheimer’s disease and restore memory.
Researchers at MIT have developed a method to stimulate brain tissue using external magnetic fields and injected magnetic nanoparticles — a technique allowing direct stimulation of neurons, which could be an effective treatment for a variety of neurological diseases, without the need for implants or external connections.
Researchers have come up with a new way to evaluate how well computers can divine information from images. The team describes its new system as a “visual Turing test,” after the legendary computer scientist Alan Turing’s test of the extent to which computers display human-like intelligence.
Thousands of genetic “dimmer” switches, regions of DNA known as regulatory elements, were turned up high during human evolution in the developing cerebral cortex, according to new research from the Yale School of Medicine.
Finally this week, a new study finds that giving a drug that changes the neurochemical balance in the brain causes a greater willingness to engage in prosocial behaviors, such as ensuring that resources are divided more equally.
