The researchers report in the Journal of Neuroscience that when mice allowed to exercise regularly experienced a stressor — exposure to cold water — their brains exhibited a spike in the activity of neurons that shut off excitement in the ventral hippocampus, a brain region shown to regulate anxiety. These findings potentially resolve a discrepancy.. read more →
Children with dyslexia may read better after playing action video games that stress mayhem, not literacy, a contested study suggests. Playing fast-paced Wii video games for 12 hours over two weeks markedly increased the reading speed of 7- to 13-year-old kids with dyslexia, with no loss of reading accuracy, says a team led by psychologist.. read more →
The results of these projects suggest the future potential for linking multiple brains to form what the research team is calling an “organic computer,” which could allow sharing of motor and sensory information among groups of animals. The study was published Feb. 28, 2013, in the journal Scientific Reports. “Our previous studies with brain-machine interfaces.. read more →
Aug. 15, 2011 — Ultra-thin electronics, which can be placed on the skin as easily as a temporary tattoo, could pave the way for patient monitoring systems that would avoid the need for bulky equipment. In one study, the adhesive patch was applied to a person’s chest to pick up electrical signals produced by the.. read more →
Researchers at XenoBiotic Laboratories are using cryo-imaging and quantitative autoradiography to provide quantitative tissue distribution data as part of a preclinical ADME program. Autoradioluminograms placed through 3D reconstructed organs are highlighted in this video. read more →
For the first time, researchers decipher the retina’s neural code for brain communication to create novel, more effective prosthetic retinal device for blindness. Two researchers at Weill Cornell Medical College have deciphered a mouse’s retina’s neural code and coupled this information to a novel prosthetic device to restore sight to blind mice. The researchers say.. read more →
Signs of depression can be turned on and off in mice with the flip of a switch. Activating or silencing the behavior of certain brain cells with laser light causes the animals to change their depressive behavior, two new studies find. Although the experiments were done in rodents, the results have direct relevance to human.. read more →
A woman who is paralysed from the neck down has stunned doctors with her extraordinary skill at using a robotic arm that is controlled by her thoughts alone. The 52-year-old patient, called Jan, lost the use of her limbs more than 10 years ago to a degenerative disease that damaged her spinal cord. The disruption.. read more →
A team of University of Minnesota biomedical engineers and researchers from Mayo Clinic published a groundbreaking study today that outlines how a new type of non-invasive brain scan taken immediately after a seizure gives additional insight into possible causes and treatments for epilepsy patients. The new findings could specifically benefit millions of people who are.. read more →
Blind people could soon be able to read street signs using an implant that translates the alphabet into Braille and beams an image of the Braille directly to visual neurons at the back of the eye. The implant is a modified version of a class of devices called retinal prostheses, which are used to restore.. read more →
