Treatment of obstructive sleep apnea (OSA) in children normalizes disturbances in the neuronal network responsible for attention and executive function, according to a new study. "OSA is known to be associated with deficits in attention, cognition, and executive function," said lead author Ann Halbower, MD, Associate Professor at the Children's Hospital Sleep Center and University of Colorado Denver. "Our study is the first to show that treatment of OSA in children can reverse neuronal...

Young Birds Use Their Brain To Learn Songs
2012-05-21 08:55:04

Brett Smith for RedOrbit.com Male songbirds use a versatile part of the brain to learn their father´s song during the early stages of development, according to a report published yesterday in the online version of Nature. Researchers at the University of California at San Francisco (UCSF) found that Bengalese finch males use a trial-and-error method in learning the song they will use to attract a mate once they reach maturity. The learning process begins around 40 days after...

The baseline level of distrust is distinct and separable from our inborn lie detector Fool me once, shame on you. Fool me twice, shame on my parahippocampal gyrus. Scientists at the Virginia Tech Carilion Research Institute have found that suspicion resides in two distinct regions of the brain: the amygdala, which plays a central role in processing fear and emotional memories, and the parahippocampal gyrus, which is associated with declarative memory and the recognition of scenes....

Famous 1848 case of a man who survived a terrible accident has modern parallel Poor Phineas Gage. In 1848, the supervisor for the Rutland and Burlington Railroad in Vermont was using a 13-pound, 3-foot-7-inch rod to pack blasting powder into a rock when he triggered an explosion that drove the rod through his left cheek and out of the top of his head. As reported at the time, the rod was later found, "smeared with blood and brains." Miraculously, Gage lived, becoming the most famous...

SAN DIEGO, May 17, 2012 /PRNewswire/ -- Ceregene Inc., a biotechnology company developing treatments for neurodegenerative diseases such as Parkinson's disease, will present new data demonstrating long-term, biologically-active expression of neurturin, a nervous system growth factor delivered to the degenerating dopamine nerves in patients with Parkinson's disease following treatment with CERE-120 (AAV2-neurturin). Raymond T. Bartus, Ph.D., Ceregene's chief scientific officer and...

Caltech researchers find that loss aversion may be the culprit In sports, on a game show, or just on the job, what causes people to choke when the stakes are high? A new study by researchers at the California Institute of Technology (Caltech) suggests that when there are high financial incentives to succeed, people can become so afraid of losing their potentially lucrative reward that their performance suffers. It is a somewhat unexpected conclusion. After all, you would think that the...

Image Credit: Photos.com UCSF study offers path for studying learning, decision-making, PTSD UCSF scientists have identified patterns of brain activity in the rat brain that play a role in the formation and recall of memories and decision-making. The discovery, which builds on the team's previous findings, offers a path for studying learning, decision-making and post-traumatic stress syndrome. The researchers previously identified patterns of brain activity in the rat...

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...

The ability to navigate using spatial cues was impaired in mice whose brains were minus a channel that delivers potassium – a finding that may have implications for humans with damage to the hippocampus, a brain structure critical to memory and learning, according to a Baylor University researcher. Mice missing the channel also showed diminished learning ability in an experiment dealing with fear conditioning, said Joaquin Lugo, Ph.D., the lead author in the study and an assistant...

Study on smokers' brains may mark dawn of a new age in advertising Advertisers and public health officials may be able to access hidden wisdom in the brain to more effectively sell their products and promote health and safety, UCLA neuroscientists report in the first study to use brain data to predict how large populations will respond to advertisements. Thirty smokers who were trying to quit watched television commercials from three advertising campaigns, which all ended by showing the...

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...
