Scans reveal how genes alter circuit hub to shape temperament -- NIH study A personality profile marked by overly gregarious yet anxious behavior is rooted in abnormal development of a circuit hub buried deep in the front center of the brain, say scientists at the National Institutes of Health. They used three different types of brain imaging to pinpoint the suspect brain area in people with Williams syndrome, a rare genetic disorder characterized by these behaviors. Matching the scans to...

Evidence Builds That Meditation Strengthens The Brain Earlier evidence out of UCLA suggested that meditating for years thickens the brain (in a good way) and strengthens the connections between brain cells. Now a further report by UCLA researchers suggests yet another benefit. Eileen Luders, an assistant professor at the UCLA Laboratory of Neuro Imaging, and colleagues, have found that long-term meditators have larger amounts of gyrification ("folding" of the cortex, which may allow the...

(Ivanhoe Newswire) -- My toy, my snack, my juice box, kids can be selfish! A new study suggests that age-associated improvements in the ability to consider others are linked with maturation of the brain region involved in self control. The study may help to explain why children can be selfish when they are taught better and could improve educational strategies that are designed to encourage successful social behavior. Social interactions involve two parties who want the greatest possible...

Caltech biologists locate brain's processing point for acoustic signals essential to human communication In both animals and humans, vocal signals used for communication contain a wide array of different sounds that are determined by the vibrational frequencies of vocal cords. For example, the pitch of someone's voice, and how it changes as they are speaking, depends on a complex series of varying frequencies. Knowing how the brain sorts out these different frequencies–which are...

Neuron paper by UB researchers reveals why chronic stress in adolescence impairs memory, may trigger mental illness Chronic stress has a more powerful effect on the brain during adolescence than in adulthood and now there's proof at the molecular level. "We have identified a causal link between molecules and behaviors involved in stress responses," says Zhen Yan, PhD, a professor in the Department of Physiology and Biophysics in the UB School of Medicine and Biomedical Sciences. "It's...

A new study suggests that age-associated improvements in the ability to consider the preferences of others are linked with maturation of a brain region involved in self control. The findings may help to explain why young children often struggle to control selfish impulses, even when they know better, and could impact educational strategies designed to promote successful social behavior. Human social interactions often involve two parties who want to maximize their own outcomes while...

Creative Thinking Not Just For Right-Side Of Brain
2012-03-05 13:39:16

Researchers say that the left hemisphere of the brain may not be just logic and math, but could also help play a big role in creativity as well. Researchers from the University of Southern California (USC) are working to try and pin down the exact source of creativity in the brain. "We want to know: how does creativity work in the brain?" Lisa Aziz-Zadeh, assistant professor of neuroscience at the USC Dornsife College of Letters, Arts and Sciences, said in a statement. The right...

In a mouse model of Alzheimer's disease, memory problems stem from an overactive enzyme that shuts off genes related to neuron communication, a new study says. When researchers genetically blocked the enzyme, called HDAC2, they 'reawakened' some of the neurons and restored the animals' cognitive function. The results suggest that drugs that inhibit this particular enzyme would make good treatments for some of the most devastating effects of the incurable neurodegenerative disease. "It's...

UCSF Study Shows Digital Cognitive Training Improves Brain Function and Behavior for People with Schizophrenia People with schizophrenia who completed 80 hours of intensive, computerized cognitive training exercises were better able to perform complex tasks that required them to distinguish their internal thoughts from reality. As described in the journal Neuron on Feb. 22, 2012, a small clinical study conducted at the San Francisco VA Medical Center (SFVAMC) and the University of...

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...
