Mysterious DNA modification appears more in the brain under stress

With advances in genomics, scientists are discovering additional components of the DNA alphabet in animals. Do these unusual chemical modifications of DNA have a special meaning, or are they just signs that cellular machines are making mistakes?

Research findings reveal which brain region stimulates divergent behavior

Have you ever been stuck in a rut, going through the same motions day in and day out? How do you motivate to change your behavior?

Study uses noninvasive brain imaging to evaluate surgical proficiency of medical students

While simulation platforms have been used to train surgeons before they enter an actual operating room, few studies have evaluated how well trainees transfer those skills from the simulator to the OR.

Researchers use new equation to map self-esteem in the human brain

A team of UCL researchers has devised a mathematical equation that can explain how our self-esteem is shaped by what other people think of us, in a new study published in the scientific journal eLife.

Jealousy study in pair-bonded monkeys offers insight into human emotions and behavior

It's perhaps one of the most common emotions to feel in a relationship, but one that's virtually untouched when it comes to studying relationships in monogamous primate species.

Brain function does not die immediately after the heart stops finds study

According to new research, people can be aware that they are dead after their heart has stopped beating.

Study aims to develop biomarkers of prematurity for predicting neurodevelopmental outcomes

Natasha Leporé, PhD, a principal investigator in the Department of Radiology and Imaging at Children's Hospital Los Angeles, has been awarded $1.7 million from the National Institute of Biomedical Imaging and Bioengineering of the NIH to study the impact of prematurity on brain development.

Brazilian researchers find more significant cognitive deficits among early-onset cocaine users

People who begin using cocaine during adolescence display more significant cognitive deficits than people who begin using the drug in adulthood.

Four genes associated with OCD identified

There are found genes that have been identified to be associated with obsessive compulsive disorder (OCD). These genes have been found to alter the circuitry of the brain in a manner that could lead to OCD. These genetic links also point to the fact why OCD sometimes runs in families. The study is published in the latest issue of Nature Communications.

Magic mushrooms chemical Psilocybin for treatment of hard-to treat depression

A new study from UK has found efficacy of psilocybin – a chemical found in “magic mushrooms”, in severe depression. The study involved 19 patients with severe depression. The patients took the psilocybin and around half of them improved and reported maintained improvement after 5 weeks of therapy. The patients however also received psychological care along with the treatment.

Researchers find how tDCS could increase performance of associative learning

HRL Laboratories, LLC, researchers have determined how non-invasive transcranial direct current stimulation (tDCS) could increase performance of associative learning.

Siemens Healthineers’ MAGNETOM Terra 7T MRI scanner cleared by FDA for diagnostic imaging

The Food and Drug Administration has cleared the MAGNETOM Terra magnetic resonance imaging (MRI) scanner from Siemens Healthineers - the first-ever 7 Tesla (7T) MRI cleared for diagnostic imaging.

Improving synchronization of brain waves enhances learning and self-control

Robert Reinhart calls the medial frontal cortex the "alarm bell of the brain." "If you make an error, this brain area fires," says Reinhart, an assistant professor of psychological and brain sciences at Boston University. "If I tell you that you make an error, it also fires.

Brain’s motor signals sharpen sound perception, research suggests

Whether it is dancing or just tapping one foot to the beat, we all experience how auditory signals like music can induce movement. Now new research suggests that motor signals in the brain actually sharpen sound perception, and this effect is increased when we move in rhythm with the sound.

Persistent cannabis use linked to violent behavior among young people with mental illness

A new study by researchers at the Institut en santé mentale de Montréal demonstrates that sustained used of cannabis is associated with an increase in violent behavior in young people after discharge from a psychiatric hospital.

Researchers find surprising differences in first-ever whole-brain map of inhibitory neurons

Researchers at Penn State College of Medicine have collaborated on the first-ever quantitative whole-brain map of inhibitory neurons in the mouse brain. These brain cells play a crucial role in regulating response to stimuli and have been widely implicated in many psychiatric conditions.

UC Berkeley researchers to develop new ultra-high-resolution MRI brain scanner

Functional magnetic resonance imaging, or fMRI, has transformed our view of the brain, allowing researchers to pinpoint areas associated with everything from depression and dementia to playing chess and engaging in sex.

Study uses ferret model to elucidate key mechanisms for gyrus formation

The human brain is highly developed with higher functions compared to other animals, thanks to which humans are believed to have acquired special abilities. One of the important factors considered to contribute to the development of the brain is the gyrus, the fold on the cerebral cortex surface.

MPFI scientist receives $2.4 million NIH grant to study neural circuits in the cerebral cortex

Dr. David Fitzpatrick, Scientific Director and CEO at the Max Planck Florida Institute for Neuroscience, has been awarded a $2.4 million five-year grant from the National Eye Institute of the National Institutes of Health to study the functional organization of neural circuits in the cerebral cortex, specifically, in the area of brain responsible for processing visual information.

New non-invasive biomarker detects Alzheimer's disease before occurrence of first symptoms

Absence of a prefrontal activation during sensory gating of simple tones detects the Alzheimer's disease (AD) before the occurrence of the first symptoms. Sanja Josef Golubic Ph.D., physicists at the Department of Physics, Faculty of Science, University of Zagreb, reveals the high potential, absolutely non-invasive biomarker of AD pathology in a new study published in the journal Human Brain Mapping. Josef Golubic found a discrete, individual biomarker of AD with "ideal" properties.
