New article explores in-depth the positive health gains associated with sleep. Malibu, CA (PRWEB) April 23, 2014 An article published April 9th in TIME magazine cited a variety of sources from the scientific community which all concluded that a natural night’s sleep is essential to good health, happiness, and better personal performance. The need for sleep varies significantly between individuals, with some people functioning well after only five hours of sleep, while other require as...

Neuroscientists have discovered a brain pathway that underlies the emotional behaviors critical for survival. New research by the University of Bristol, published in the Journal of Physiology today [23 April], has identified a chain of neural connections which links central survival circuits to the spinal cord, causing the body to freeze when experiencing fear. Understanding how these central neural pathways work is a fundamental step towards developing effective treatments for...

New research published today out of the University of Calgary's Hotchkiss Brain Institute (HBI) uncovers a mechanism to promote growth in damaged nerve cells as a means to restore connections after injury. Dr. Doug Zochodne and his team have discovered a key molecule that directly regulates nerve cell growth in the damaged nervous system. His study was published in the prestigious journal Nature Communications, with lead authors Drs. Kim Christie and Anand Krishnan. "We made the surprising...

In noting Bicycle Day 2014, author Bryan W. Brickner tells the story of Albert Hoffman’s first intentional use of lysergic acid diethylamide (LSD) through the lens of serotonin, the neurotransmitter system LSD modulates. PubMed provides the quotes and science for an immune dialogue, an early life tale, circadian clock notes and bowels (irritable and otherwise). Chicago, IL (PRWEB) April 19, 2014 “Serotonin has a synaptic transmission,” opened Bryan W. Brickner, “and 71 years ago...

Attack by own immune system may kill neurons in Parkinson's disease The cause of neuronal death in Parkinson's disease is still unknown, but a new study proposes that neurons may be mistaken for foreign invaders and killed by the person's own immune system, similar to the way autoimmune diseases like type I diabetes, celiac disease, and multiple sclerosis attack the body's cells. The study was published April 16, 2014, in Nature Communications. "This is a new, and likely controversial,...

redOrbit Staff & Wire Reports - Your Universe Online In research that should provide a more detailed picture of how memory works, scientists from the Salk Institute have developed a new model explaining how neurons retain select memories a few hours after an event. “Previous models of memory were based on fast activity patterns,” study author and Howard Hughes Medical Institute Investigator Terry Sejnowski explained in a statement on Wednesday. “Our new model of memory makes...

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...

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...
