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...

Rats Recall Past To Make Daily Decisions

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

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...

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...

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...

Researchers interested in determining the direct effects of a high saturated fat and high cholesterol (HFHC) diet on implanted fetal hippocampal tissues have found that in middle-aged laboratory rats the HFHC diet elevated microglial activation and reduced neuronal development. While the resulting damage was due to an inflammatory response in the central nervous system, they found that the effects of the HFHC diet were alleviated by the interleukin (IL)-1 receptor antagonist IL-1Ra, leading...

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...

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...
