Researchers at the University of Toronto say a sleep disorder that causes people to act out their dreams is the best current predictor of brain diseases like Parkinson's and Alzheimer's. "Rapid-eye-movement sleep behavior disorder (RBD) is not just a precursor but also a critical warning sign of neurodegeneration that can lead to brain disease," says associate professor and lead author Dr. John Peever. In fact, as many as 80 to 90 per cent of people with RBD will develop a brain disease."...

A major challenge of systems biology is understanding how phenomena at the cellular scale correlate with activity at the organism level. A concerted effort has been made especially in the brain, as scientists are aiming to clarify how neural activity is translated into consciousness and other complex brain activities. One example of the technologies needed is whole-brain imaging at single-cell resolution. This imaging normally involves preparing a highly transparent sample that minimizes...

Six months off may not be long enough for the brains of football players to completely heal after a single season, putting them at even greater risk of head injury the next season. "I don't want to be an alarmist, but this is something to be concerned about," said Jeffrey J. Bazarian, M.D., associate professor of Emergency Medicine at the University of Rochester School of Medicine and Dentistry and lead author of the study, published in PLOS ONE. "At this point we don't know the...

Marijuana Use On A Casual Basis Still Linked To Brain Abnormalities
2014-04-16 11:17:29

Brett Smith for redOrbit.com - Your Universe Online With the movement to legalize marijuana appearing to gain momentum across the US, new attention is being given to the negative effects the drug has on the brain. According to a new study published on Wednesday in the Journal of Neuroscience, even causal use of marijuana can have a significant impact of the shape, volume and density of certain brain regions. The study team also found that the more marijuana a person smoked – the more...

Everyday activities can improve brain fitness. Ace Medical Group doctor provides spring brain exercises. Rock Hill, SC (PRWEB) April 14, 2014 "Everyone needs to realize how we are giving up brain activity by giving up everyday tasks," says Dr. Grewal, an Internal medicine physician and author of the book 'Dementia Express: Lose Your Memory in 100 Ways,' a rare satirical on brain health. There are easy and routine ways of exercising one's brain. Here are some ways a...

May 15 event was intended to raise public awareness and honor the 60,000 people in our community with epilepsy, but has been overshadowed by a debate between balloon manufacturers and vocal environmental groups. St. Paul, MN (PRWEB) April 12, 2014 The Epilepsy Foundation of Minnesota (EFMN) is modifying plans for its May 15 “Rise Above Seizures” balloon release. The event was intended to raise public awareness and honor the 60,000 people in our community with epilepsy, but has been...

To accommodate a lifetime of scents and aromas, mammals have hundreds of genes that each produce a different odorant receptor. The complex and diverse olfactory system they build remains adaptable, but a new study in the journal Science shows that the system's flexibility, or plasticity, has its limits. Working in mice, Brown University scientists found that the fundamental neural wiring map between the nose and the brain becomes established in a critical period of early development and then...

Stowers investigators reveal a developmental switch in targeting capacity of olfactory neurons The human nose expresses nearly 400 odorant receptors, which allow us to distinguish a large number of scents. In mice the number of odor receptors is closer to 1000. Each olfactory neuron displays only a single type of receptor and all neurons with the same receptors are connected to the same spot, a glomerulus, in the brain. This convergence, or wiring pattern, is often described as an...

The cerebellum is a section of the brain that is most in charge of cognitive functions and motor skills. Formation and Orientation The cerebellum can be found at the bottom of the brain behind the pons and below that cerebral cortex under a layer of dura mater. It is considered as a part of the "hindbrain". The cerebellum is anatomically divided into two separate hemispheres, marked by the 'vermis', a small midline zone between the left and right hemispheres. But three lobes can be...

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...
