New research has revealed a previously unknown mechanism in the body which regulates a hormone that is crucial for motivation, stress responses and control of blood pressure, pain and appetite. The breakthrough could be used to design drugs to help fight health problems connected with these functions in the future. Researchers at the University of Bristol and University College London found that lactate – essentially lactic acid – causes cells in the brain to release more noradrenaline...

Study in human cells may improve ability to identify useful drug targets In most cases of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, a toxin released by cells that normally nurture neurons in the brain and spinal cord can trigger loss of the nerve cells affected in the disease, Columbia researchers reported today in the online edition of the journal Neuron. The toxin is produced by star-shaped cells called astrocytes and kills nearby motor neurons. In ALS, the death...

[ Watch the Video: Lights Out For Your Hearing ] April Flowers for redOrbit.com - Your Universe Online It has long been known that if you take away once sense from a person, the other four will become more finely tuned. A new study, published in Neuron, reveals that minimizing a person's sight for as little as a week may help improve the brain's ability to process hearing. Stevie Wonder and Ray Charles – both blind musicians – are often cited by music experts as examples of how a...

Simulated blindness gives adult mice sharper hearing, according to a study published today by University of Maryland and Johns Hopkins University scientists. College Park, MD (PRWEB) February 05, 2014 Call it the Ray Charles Effect: a young child who is blind develops a keen ability to hear things others cannot. Researchers have known this can happen in the brains of the very young, which are malleable enough to re-wire some circuits that process sensory information. Now researchers at...

Brain Edits, Splices Past Memories With Current Events

[ Watch the Video: Brains Edits Past Memories ] Brett Smith for redOrbit.com - Your Universe Online While we may like to think of our brains as a video camera that records events exactly as they happen, a new study from scientists at Northwestern University has found that the brain acts more like an editing studio, cutting and splicing past events based on present circumstances. "When you think back to when you met your current partner, you may recall this feeling of love and...

A new study proves inactivity detrimentally changes the structure of brain cells impacting heart health. TrekDesk treadmill desk offers a potential preventative solution. Scottsdale, AZ (PRWEB) February 04, 2014 TrekDesk has reported over the years on numerous studies that have shown the positive impact of walking on cognition and overall physical/mental health however a new study available for review in the US National Library of Medicine sheds light on the potential health risks brought...

Robot Uses Insect Brain To Navigate Arena

[ Watch the Video: Robotic Honey Bee Brains ] Lee Rannals for redOrbit.com - Your Universe Online The worst fears of those suffering from insectophobia (entomophobia) are being met with the latest development out of Berlin — robots with insect brains. Scientists using the nervous system of the honeybee as a model have developed a robot that perceives environmental stimuli and learns to react to them. This robot was able to replicate the sensorimotor network of the insect brain,...

Our brains have billions of neurons grouped into different regions. These regions often work alone, but sometimes must join forces. How do regions communicate selectively? Stanford researchers may have solved a riddle about the inner workings of the brain, which consists of billions of neurons, organized into many different regions, with each region primarily responsible for different tasks. The various regions of the brain often work independently, relying on the neurons inside that...

“Psychogenic Non-Epileptic Seizures: A Guide” by Lorna Myers, Ph.D. provides readers with clear explanations about this serious psychological condition as well as tools to get back to a healthy life. New York, NY (PRWEB) January 31, 2014 Psychogenic Non-epileptic Seizures (PNES) can have devastating effects on those who develop it . PNES is a serious psychological condition that is still not well understood by doctors or the public. These seizures look very much like epileptic...

Autistic Brains Create 42 Percent More Information During Rest: Study
2014-01-31 14:00:26

Lee Rannals for redOrbit.com - Your Universe Online A new study published in the journal Frontiers in Neuroinformatics shows that autistic brains can create 42 percent more information on average while at rest. The research, performed by Case Western Reserve University and University of Toronto neuroscientists, could explain an autistic child’s detachment from his/her environment. “Our results suggest that autistic children are not interested in social interactions because their...

Cerebellum
2013-07-29 09:48:00

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...

Midbrain

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...
