Neuroimaging study ties the degradation of circuitry in one area of the brain to reduced efficiency of executive function in older adults.
A novel two-person MRI study reveals what goes on in the brain when two people touch and cuddle. During the interaction, the subjects' brain activity synchronized.
When exposed to auditory stimulation, visual areas of the brain decreased in activity. Findings suggest sound can strongly draw attention away from what we are looking at.
Rat R222 was born with hydrocephalus. Neuroimaging revealed most of its brain had compressed and collapsed as it filled with fluid. However, despite its condition, the animal was still able to see, hear, smell, and feel like other animals. The study sheds new light on neuroplasticity, and the findings could have implications for the development of new machine learning technologies.
Despite previous findings, researchers have found precapillary sphincters in the brain. The study reports the precapillary sphincters may play a major role in disturbances of the brain's blood supply and blood pressure.
Methylphenidate may boost norepinephrine levels in the prefrontal cortex, which in turn regulates dopaminergic neurons firing in the striatum, when a reward is delivered. The study sheds new light on how medications for ADHD affect the reward system in the brain.
Combining neuroimaging data and deep learning technologies, researchers have developed a model of the human brain that simulates patterns of neurological impairment better than existing models.
Blood can bring more oxygen into the brains of mice following exercise as increased respiration increases oxygen levels in hemoglobin.
Two new neuroimaging studies shed light on structural and functional abnormalities in the brains of those with major depressive disorder.
Neural pathways for learning differ depending on how each person has learned a new skill.
Stronger activation for words over pseudo-words was seen in deep layers of the visual word form area. The activation caused top-down projections from higher language areas of the brain.
Fluctuations in the dopaminergic midbrain play a critical role in risky decision making.
