Too much uncontrolled brain activity in specific areas could lead to cognitive impairments, a new study reveals.
Researchers believe their findings could change the way scientists understand how the brain works.
A new study outlines how researchers have been able to deliver concentrated amounts of drugs directly into the brains of rats by using ultrasound.
Cerebral blood flow is reduced in the Broca's area of people who stutter, researchers report. Additionally, the more severely a person stutters, the less blood flows to this area of the brain.
Researchers use fast fMRI to track the brain activity that occurs during thought. The study could be a significant step toward mapping the neural networks responsible for attention, perception and other cognitive functions.
Researchers report people with insomnia showed altered brain activity in areas associated with self awareness and the tendency to ruminate, compared to those who sleep well.
Researchers have created a new math model that successfully reproduces complex brain activity during deep sleep.
