In a new study researchers show that they could make faint sensations more vivid by triggering a brain rhythm that appears to shift sensory attention. The study in mice, reported in Nature Neuroscience, provides the first direct evidence that the brain’s “gamma” rhythms have a causal role in processing the sense of touch.
Strongly influenced by their self-interest, humans do not protest being overcompensated, even when there are no consequences, researchers in Georgia State University’s Brains and Behavior Program
As people grow older, they often have difficulty falling asleep and staying asleep, and tend to awaken too early in the morning. In individuals with Alzheimer’s disease, this common and troubling symptom of aging tends to be especially pronounced.
Youngsters who are more physically fit have more fibrous and compact white-matter tracts in the brain than their less-fit counterparts, according to new research appearing in the August 19 edition of the journal Frontiers in Human Neuroscience.
As children learn basic arithmetic, they gradually switch from solving problems by counting on their fingers to pulling facts from memory. The shift comes more easily for some kids than for others, but no one knows why.
Our brains are able to judge the trustworthiness of a face even when we cannot consciously see it, a team of scientists has found.
People not only use their eyes to see, but also to move. It takes less than a fraction of a second to execute the loop that travels from the brain to the eyes, and then to the hands and/or arms.
For many animals, making sense of the clutter of sensory stimuli is often a matter or literal life or death.
Issues of crime and punishment, vengeance and justice date back to the dawn of human history, but it is only in the last few years that scientists have begun exploring the basic nature of the complex neural processes in the brain that underlie these fundamental behaviors.
A specific electrical pattern has been identified in the brains of genetically identical mice which accurately predicts how well individual animals will fare in stressful situations, according to new research by Duke University scientists.
The midbrain, also known as the mesencephalon is the part of the brain most responsible for vision, motor control, arousal, temperature regulation, alertness and hearing. Formation and Orientation The midbrain is found under the cerebral cortex and above the hindbrain. The mesencephalon is not divided into any other portions of the brain unlike the other two vesicles that stem from the neural tube. There are four separate lobes on the side of the cerebral aqueduct within the...
Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...
