Humans And Rodents Process Their Mistakes
2013-10-21 06:55:57

Brown University Study finds parallels in neural processing of 'adaptive control' People and rats may think alike when they've made a mistake and are trying to adjust their thinking. That's the conclusion of a study published online Oct. 20 in Nature Neuroscience that tracked specific similarities in how human and rodent subjects adapted to errors as they performed a simple time estimation task. When members of either species made a mistake in the trials, electrode recordings showed...

Proper Sleep Is Critical To Healthy Lifestyle
2013-10-16 04:19:10

April Flowers for redOrbit.com - Your Universe Online According to three new studies reported in the Journal of Clinical Sleep Medicine, It is critical that adults with a sleep illness seek medical attention and try to get between 7 and 9 hours of sleep every night to maintain a healthy lifestyle. The first study examined 2,240 adults to understand the link between obstructive sleep apnea (OSA) and mortality in Asians. The study findings show that people with severe OSA had a 2.5 times...

Birth Prepares The Brain For Sensing The World
2013-10-15 04:49:33

April Flowers for redOrbit.com - Your Universe Online Precise, well-characterized maps crucial for translating perception into understanding are built in the brain by neurons that process sensory information such as touch and vision. A new study from Kanazawa University of Japan reveals that the brain chemical serotonin is reduced in newborn mice during the act of birth. This reduction triggers sensory maps to form in the brain. The findings, published in the journal Developmental Cell,...

Brain Waves May Tell How Much We Would Pay For A Cup Of Coffee

[ Watch the Video: Coffee Prices And Brain Scans ] Lee Rannals for redOrbit.com - Your Universe Online A German neurobiologist says that Starbucks isn't charging enough for your double tall, two-pump caramel white chocolate mocha. Kai-Markus Müller is developing a new way to test prices by measuring brain waves, and he believes that Starbucks maybe missing out on some premium pricing. "Everyone thinks that they've truly figured out how to sell a relatively inexpensive product for...

Scientist Describes New Theory Of Synapse Formation In The Brain
2013-10-11 11:57:41

Forschungszentrum Juelich The human brain keeps changing throughout a person's lifetime. New connections are continually created while synapses that are no longer in use degenerate. To date, little is known about the mechanisms behind these processes. Jülich neuroinformatician Dr. Markus Butz has now been able to ascribe the formation of new neural networks in the visual cortex to a simple homeostatic rule that is also the basis of many other self-regulating processes in nature. With this...

Sleep Deprivation Cannot Be Fixed On The Weekend
2013-10-09 14:10:52

Lee Rannals for redOrbit.com - Your Universe Online Trying to recoup some lost sleep from the crazy work week on the weekend isn't as effective as one might think, according to findings reported in the American Journal of Physiology. A few days of lost sleep can have adverse side effects, such as increased daytime sleepiness, worsened daytime performance, an increase in molecules that are a sign of inflammation in the body, and impaired blood sugar regulation. Although many people...

Chronic Dizziness May Be Helped By Magnetic Stimulation
2013-10-09 04:55:36

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Johns Hopkins University School of Medicine believe that they have located a specific site in the human brain that could be one of the sources of dizziness and spatial disorientation. While dizziness can also be linked to damage to the inner ear, or to other senses such as vision, neurology instructor Dr. Amir Kheradmand and his colleagues report that they have discovered a region of the brain that plays a...

Inhibitory neuron type found to specifically suppress activation of other inhibitory neurons in cerebral cortex The cerebral cortex contains two major types of neurons: principal neurons that are excitatory and interneurons that are inhibitory, all interconnected within the same network. New research now reveals that one class of inhibitory neurons – called VIP interneurons -- specializes in inhibiting other inhibitory neurons in multiple regions of cortex, and does so under specific...

Electrooculography
2012-12-31 11:47:45

Electrooculography, sometimes shortened to EOG, is the tracing of electricity used for operation of the retina in different phases, specifically the resting potential. The results are recorded on an electrooculogram. These are interpreted for opthalmological diagnosis and in recording eye movements. Eye movement measurements: Usually, pairs of electrodes are placed either above and below the eye or to the left and right of the eye. If the eye is moved from the center position towards one...
