Brain's Visual Cortex Activates For Reward Even When Stimulus Is Removed
2013-03-22 12:15:13

Alan McStravick for redOrbit.com - Your Universe Online An international collaborative study, conducted by researchers at both KU Leuven and the Harvard Medical School, has attempted to recreate Ivan Pavlov´s famous experiment, but with a twist. Pavlov, you may know, was famous for conducting a study where a stimulus was introduced and the reward for that stimulus was slowly removed, with the aim of observing whether or not a physiological response would continue to be registered...

Salk Researchers Study Neuroscience Behind Finding Lost Items
2013-03-21 18:20:17

Alan McStravick for redOrbit.com — Your Universe Online As if it wasn´t enough that Jonas Salk was responsible for the eradication of polio, now the institute named for him is tackling an even more universally deleterious condition: understanding the neural processes behind helping you to locate lost items. Though the results of the study have been adapted to the common human experience of finding one´s misplaced keys or automobile or cell phone, the research involved...

Creative Task Performance Improved By Turning Off Brain’s ‘Filter’
2013-03-15 22:14:58

Alan McStravick for redOrbit.com — Your Universe Online As you are reading these words, your ability to comprehend their meaning is being aided, in no small part, by your brain´s prefrontal cortex. This region of the brain is helping you to maintain focus from sentence to sentence and is filtering out irrelevant thoughts, perceptions and memories. It is this thought filtration that allows you to complete a task without thoughts of when the water bill is due creeping in....

A region of the brain known to play a key role in visual and spatial processing has a parallel function: sorting visual information into categories, according to a new study by researchers at the University of Chicago. Primates are known to have a remarkable ability to place visual stimuli into familiar and meaningful categories, such as fruit or vegetables. They can also direct their spatial attention to different locations in a scene and make spatially-targeted movements, such as...

Specific Brain Region Plays Important Role In Reducing Anxiety
2013-03-07 09:13:26

April Flowers for redOrbit.com - Your Universe Online A research team led by the Columbia University Medical Center (CUMC) has found the first evidence that selective activation of the dentate gyrus, a portion of the hippocampus, can reduce anxiety without affecting learning. The findings suggest therapies targeting this brain region could treat certain anxiety disorders, such as panic disorder and post-traumatic stress syndrome (PTSD). These treatments, as described in the study, would...

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,"...

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...
