Sensory perception is not superficial brain work
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.... Read More...

A rat had basically no brain, but it could still see, hear, smell, and feel
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.... Read More...
Researcher discovers previously rejected function in the brain’s blood vessels
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. ... Read More...
Rich rewards: ADHD medication’s effect on the brain
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.... Read More...
Brain model offers new insights into damage caused by stroke and other injuries
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.... Read More...
Respiration key to increase oxygen in the brain
Blood can bring more oxygen into the brains of mice following exercise as increased respiration increases oxygen levels in hemoglobin.... Read More...
Imaging reveals pathways behind depression
Two new neuroimaging studies shed light on structural and functional abnormalities in the brains of those with major depressive disorder.... Read More...
How our brains remember things depends upon how we learn them
Neural pathways for learning differ depending on how each person has learned a new skill.... Read More...
Neuroimaging reveals hidden communication between brain layers during reading
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.... Read More...
Spontaneous brain fluctuations influence risk-taking
Fluctuations in the dopaminergic midbrain play a critical role in risky decision making.... Read More...
Brain structure determines individual differences regarding music sensitivity
White matter connectivity between the auditory processing areas and brain areas associated with reward may explain why we like, or dislike music.... Read More...
NIH Study of Brain Energy Patterns Provides New Insights into Alcohol Effects
Neuroimaging research from NIH/NIAAA provides a new method to characterize how brain activity relates to glucose consumption, which could help us understand how alcohol and other substances and activities affect our brains.... Read More...
