Marsupials Handedness Depends On Gender
2013-03-06 10:50:43

BioMed Central Boys are right-handed, girls are left...Well at least this is true for sugar gliders (Petaurus breviceps) and grey short-tailed opossums (Monodelphis domestica), finds an article in BioMed Central's open access journal BMC Evolutionary Biology, and shows that handedness in marsupials is dependent on gender. This preference of one hand over another has developed despite the absence of a corpus collosum, the part of the brain which in placental mammals allows one half of the...

Emotional appeals could be more effective than celebrities when promoting products related to a consumer's identity, according to a new study in the Journal of Consumer Research. "Specific emotions can help consumers strengthen their identities by providing information about how to feel a particular identity, especially when emotions are associated with distinct patterns of action. Consumers tend to choose products that bolster emotions associated with a particular identity," write authors...

Hands Free Does Not Mean Brain Free

redOrbit Staff & Wire Reports - Your Universe Online Making a left-hand turn at a busy intersection while talking on a hands-free cellphone could be the “most dangerous” thing we do on the road due to the high level of brain activation involved, according to a new Canadian study. Researchers tested healthy young drivers operating a novel driving simulator equipped with a steering wheel, brake pedal and accelerator inside a high-powered functional MRI. This methodology...

Rat Memory Study Could Open The Door To Treat Alzheimer's Disease
2013-02-27 16:03:14

Brett Smith for redOrbit.com - Your Universe Online Researchers from Indiana University have found that rats have a capacity for “source memory,” a finding that could have implications for both future animal studies and the treatment of human memory disorders. According to the IU team´s report in Current Biology, a rat is capable of remembering how it got a certain food reward. "Researchers can now study in animals what was once thought an exclusively human domain,"...

A team of political scientists and neuroscientists has shown that liberals and conservatives use different parts of the brain when they make risky decisions, and these regions can be used to predict which political party a person prefers. The new study suggests that while genetics or parental influence may play a significant role, being a Republican or Democrat changes how the brain functions. Dr. Darren Schreiber, a researcher in neuropolitics at the University of Exeter, has been working...

Scientists at UC Santa Barbara are researching cocaine addiction, part of a widespread problem, which, along with other addictions, costs billions of dollars in damage to individuals, families, and society. Laboratory studies at UCSB have revealed that the diminished brain function and learning impairment that result from cocaine addiction can be treated —— and that learning can be restored. Karen Szumlinski, a professor in the Department of Psychological & Brain Sciences...

How Unconscious Processing Improves Decision-making Shown By Brain Imaging Research
2013-02-13 10:30:00

Carnegie Mellon University When faced with a difficult decision, it is often suggested to "sleep on it" or take a break from thinking about the decision in order to gain clarity. But new brain imaging research from Carnegie Mellon University, published in the journal "Social Cognitive and Affective Neuroscience," finds that the brain regions responsible for making decisions continue to be active even when the conscious brain is distracted with a different task. The research provides...

Researchers at the Institute for Comprehensive Medical Science, Fujita Health University and the National Institute for Physiological Sciences, Japan, along with colleagues from 9 other institutions, have identified an exceptional mouse model of schizophrenia. After screening over 160 mutant mouse strains with a systematic battery of behavioral tests, they identified a mutant mouse lacking the Schnurri-2 protein (Shn-2 KO) that exhibits behavioral deficits and other brain features consistent...

Neuroscientists Locate Fear Memory In The Amygdala
2013-01-29 04:47:29

April Flowers for redOrbit.com - Your Universe Online A noise in the dark, a rustle in the undergrowth; these are sounds likely to make an animal or a person stop sharply and be still, anticipating a predator. Freezing is part of the natural fear response, a reaction to a stimulus in the environment and part of how the brain decides whether to be afraid of it. A new study released by a neuroscience group at Cold Spring Harbor Laboratory (CSHL) examines how fear responses are learned,...

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
2013-03-05 13:54:00

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...
