Brain Activity May Be Partially Responsible For Drug Use In Teens
2012-04-30 04:38:30

A new imaging study has reportedly discovered a link between diminished activity in part of the brain with the likelihood that a teenager will start smoking, drinking, or abusing drugs. The research, said to be the largest imaging study of the human brain ever conducted, was completed by an international team of scientists including Robert Whelan and Hugh Garavan of the University of Vermont. The researchers looked at nearly 1,900 14-year-old participants, and discovered that many of the...

They say you can´t teach an old dog new tricks. Fortunately, this is not always true. Researchers at the Netherlands Institute for Neuroscience (NIN-KNAW) have now discovered how the adult brain can adapt to new situations. Their study may be significant in the treatment of neurodevelopmental disorders such as epilepsy, autism and schizophrenia. Ability to learn Our brain processes information in complex networks of nerve cells. The cells communicate and excite one another through...

A study by a new member of the Medical Faculty of the University of Geneva and a group of American researchers opened a novel window on the neuronal circuits involved What happens at the level of individual neurons while we learn? This question intrigued the neuroscientist Daniel Huber, who recently arrived at the Department of Basic Neuroscience at the UNIGE. During his stay in the United States, he and his team tried to unravel the network mechanisms underlying learning and memory at the...

Newly developed analytic device 'Flywalk' allows accurate studies of insect behavior to be made In collaboration with colleagues from Portugal and Spain, researchers at the Max Planck Institute for Chemical Ecology in Jena, Germany, have developed an apparatus that automatically applies odors to an airstream, while filming and analyzing the behavior of insects simultaneously. The system is called Flywalk and consists of glass tubes, airstream regulators, and a video camera. The reactions...

Circadian rhythm disturbances in elderly mice traced to weakened cells Older animals show cellular changes in the brain "clock" that sets sleep and wakeful periods, according to new research in the April 25 issue of The Journal of Neuroscience. The findings may help explain why elderly people often experience trouble sleeping at night and are drowsy during the day. Like humans, mice experience shifts in daily activities and sleep patterns as they age. To find out why, researchers...

New technology bypasses spinal cord and delivers electrical signals from brain directly to muscles A new Northwestern Medicine brain-machine technology delivers messages from the brain directly to the muscles -- bypassing the spinal cord -- to enable voluntary and complex movement of a paralyzed hand. The device could eventually be tested on, and perhaps aid, paralyzed patients. "We are eavesdropping on the natural electrical signals from the brain that tell the arm and hand how to...

Breakdown of white-matter pathways affects decision-making as we age If you are an aging baby boomer and you've noticed it's a bit harder to drive to unfamiliar locations or to pick a new brand of olive oil at the supermarket, you can blame it on the white matter in your brain. A brain-mapping study, published in the Apr. 11 issue of The Journal of Neuroscience, has found that people's ability to make decisions in novel situations decreases with age and is associated with a reduction in...

An artificial connection between the brain and muscles can restore complex hand movements in monkeys following paralysis, according to a study funded by the National Institutes of Health. In a report in the journal Nature, researchers describe how they combined two pieces of technology to create a neuroprosthesis — a device that replaces lost or impaired nervous system function. One piece is a multi-electrode array implanted directly into the brain which serves as a brain-computer...

UCLA-launched partnership identifies genes that boost or lessen risk of brain atrophy, mental illness and Alzheimer´s disease In the world's largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain's resistance to a variety of mental illnesses and Alzheimer's disease. Published April 15 in the advance online edition of Nature Genetics, the study also uncovers new genes that may...

Study published in Cell by Allen Institute for Brain Science examines cellular and molecular organization of human and mouse brain Scientists at the Allen Institute for Brain Science have identified similarities and differences among regions of the human brain, among the brains of human individuals, and between humans and mice by analyzing the expression of approximately 1,000 genes in the brain. The study, published online today in the journal Cell, sheds light on the human brain in...

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...

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...
