A brain stimulation technique that is used to treat tough cases of depression could be considerably improved with a new headpiece designed by University of Michigan engineers. Computer simulations showed that the headpiece—a square array of 64 circular metallic coils—could one day help researchers and doctors hit finer targets in the brain that are twice as deep as they can reach today, and without causing pain. In transcranial magnetic stimulation, special coils create a...

Recently released novel from author Lowell Evans introduces bold new approach to epilepsy awareness and education. Virginia Beach, VA (PRWEB) October 29, 2013 Author, Lowell G. Evans, has found a creative method to educate schools and the community on epilepsy awareness through his novel, The Village. Having epilepsy himself, Mr. Evans fashioned the fictional novel around working-class citizen, Kevin Bolden, who was diagnosed with epilepsy. Mr. Bolden, just like the millions people...

Nurturing Parents Offset Poverty
2013-10-29 16:33:02

Michael Harper for redOrbit.com - Your Universe Online According to a new study from the Washington University School of Medicine, children who live in poverty without nurturing parents may end up dealing with long-lasting negative consequences. According to the research, children living in poverty are less able to deal with stress and are more likely to develop life-long depression and learning disabilities. Conversely, those children who are nurtured are more likely to avoid these...

Spasticity Ranked Among Top Three Post-Stroke Symptoms Impacting Patients IRVINE, Calif., Oct. 29, 2013 /PRNewswire/ -- Seventy percent of stroke survivors living with spasticity and their caregivers rank the debilitating condition as one of the top three symptoms impacting their life post-stroke, according to a recent survey conducted by Allergan, Inc. and National Stroke Association. Spasticity, which causes muscles to contract and spasm, causing stiffness and pain ranks second only to...

Snakes Helped Evolution Of High-Quality Vision
2013-10-29 04:52:33

[ Watch the Video: What Do Snakes Have To Do With Vision Evolution? ] redOrbit Staff & Wire Reports - Your Universe Online Neuroscientists from Brazil and Japan have found new evidence in support of a theory that that human ancestors developed high-quality vision as a defense mechanism against the threat of snakes. The study, which was published Monday in the journal Proceedings of the National Academy of Sciences, demonstrated that there are specific nerve cells located in the...

VIP Treatment For Jet Lag
2013-10-28 16:18:42

Washington University in St. Louis A brain chemical that desynchronizes the cells in the biological clock helps the clock adjust more quickly to abrupt shifts in daily light/dark schedules such as those that plague modern life A small molecule called VIP, known to synchronize time-keeping neurons in the brain's biological clock, has the startling effect of desynchronizing them at higher dosages, says a research team at Washington University in St. Louis. Far from being catastrophic,...

Dendrites In Brain Act As Mini-Neural Computers
2013-10-28 10:46:15

Brett Smith for redOrbit.com - Your Universe Online Initially thought of as a simple means of sending signals in the brain, new research, published on Sunday in the journal Nature, has revealed that the dendrite sections of neurons are capable of processing information. "Suddenly, it's as if the processing power of the brain is much greater than we had originally thought," said study author Spencer Smith, an assistant professor in the UNC School of Medicine. "Imagine you're reverse...

Study aims to understand how, when the auditory system registers complex auditory-visual synchrony Imagine the brain's delight when experiencing the sounds of Beethoven's "Moonlight Sonata" while simultaneously taking in a light show produced by a visualizer. A new Northwestern University study did much more than that. To understand how the brain responds to highly complex auditory-visual stimuli like music and moving images, the study tracked parts of the auditory system involved in...

Think of the smell of an orange, a lemon, and a grapefruit. Each has strong acidic notes mixed with sweetness. And yet each fresh, bright scent is distinguishable from its relatives. These fruits smell similar because they share many chemical compounds. How, then does the brain tell them apart? How does the brain remember a complex and often overlapping chemical signature as a particular scent? Researchers at Cold Spring Harbor Laboratory (CSHL) are using the fruit fly to discover how the...

Humans And Rodents Process Their Mistakes
2013-10-21 06:55:57

Brown University Study finds parallels in neural processing of 'adaptive control' People and rats may think alike when they've made a mistake and are trying to adjust their thinking. That's the conclusion of a study published online Oct. 20 in Nature Neuroscience that tracked specific similarities in how human and rodent subjects adapted to errors as they performed a simple time estimation task. When members of either species made a mistake in the trials, electrode recordings showed...

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
2013-07-25 15:13:23

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...

Brain

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...
