Researchers Eliminate HIV from Cultured Human Cells for First Time

July 28, 2014

1 Comment

In a newly published study, researchers from Temple University detail how they created molecular tools to eliminate HIV from cultured human cells for first time. The HIV-1 virus has proved to be tenacious, inserting its genome permanently into its victims’ DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent […]

Neuroscientists Inhibit Muscle Contractions by Shining Light on Spinal Cord Neurons

June 27, 2014

0 Comments

In a newly published study, MIT neuroscientists show that they can control muscle movement by shining light on spinal cord neurons in mice. For the first time, MIT neuroscientists have shown they can control muscle movement by applying optogenetics — a technique that allows scientists to control neurons’ electrical impulses with light — to the […]

Scientists Find No Correlation Between Moon Phases and Sleep

June 16, 2014

1 Comment

New research from the Max Planck Institute of Psychiatry in Munich reveals that there is no correlation between moon phases and human sleep. Popular beliefs about the influence of the moon on humans widely exist. Many people report sleeplessness around the time of full moon. In contrast to earlier studies, scientists from the Max Planck […]

Scientists Confirm Cellular Basis for Memory by Implanting and Erasing Fear in Rats

June 2, 2014

0 Comments

In a newly published study, scientists at the University of California show the ability to selectively remove a memory and predictably reactivate it by stimulating nerves in the brain at frequencies that are known to weaken and strengthen the connections between nerve cells. Researchers at the University of California, San Diego School of Medicine have […]

Using light-field microscopy, researchers demonstrate the new technique that allowed them to simultaneously image the activity of every neuron in the entire brain of a zebrafish larva. Researchers at MIT and the University of Vienna have created an imaging system that reveals neural activity throughout the brains of living animals. Video: Melanie Gonick/MIT Researchers at […]

Infusion of Young Blood Reverses Age-Related Impairments in Mice

May 6, 2014

3 Comments

A newly published study from Stanford University found that an infusion of young blood can counteract and reverse pre-existing effects of brain aging at the molecular, structural, functional and cognitive level in mice. Something — or some things — in the blood of young mice has the ability to restore mental capabilities in old mice, […]

Researchers Use Stem Cells from Teeth to Grow Brain-Like Cells

May 1, 2014

2 Comments

New research from the University of Adelaide shows that stem cells from teeth can develop and form complex networks of brain-like cells. University of Adelaide researchers have discovered that stem cells taken from teeth can grow to resemble brain cells, suggesting they could one day be used in the brain as a therapy for stroke. […]

Bioengineers Create Neurogrid – A Circuit Board Modeled on the Human Brain

April 29, 2014

0 Comments

Stanford bioengineers have developed a circuit board modeled on the human brain that can simulate large-scale neural models in real time. Stanford bioengineers have developed a new circuit board modeled on the human brain, possibly opening up new frontiers in robotics and computing. For all their sophistication, computers pale in comparison to the brain. The […]

Study Reveals Age-Related Cognitive-Motor Decline after Age 24

April 15, 2014

2 Comments

A new study from Simon Fraser University reveals that cognitive motor performance starts to decline in individuals after age 24. It’s a hard pill to swallow, but if you’re over 24 years of age you’ve already reached your peak in terms of your cognitive motor performance, according to a new Simon Fraser University study. SFU’s […]

Neurobiologists Block the Effects of Stress

April 14, 2014

1 Comment

By deleting the REDD1 gene in mice, researchers from Yale University were able to block the synaptic and behavioral deficits caused by stress. Ketamine, an anesthetic sometimes abused as a street drug, increases the synaptic connections between brain cells and in low doses acts as a powerful antidepressant, Yale researchers have found. However, stress has […]

Researchers Use Brain Signals to Move Paralyzed Limbs

February 20, 2014

0 Comments

A newly published study details a cortical-spinal prosthesis that directs “targeted movement” in paralyzed limbs. Ithaca, New York – To help people suffering paralysis from injury, stroke or disease, scientists have invented brain-machine interfaces that record electrical signals of neurons in the brain and translate them to movement. Usually, that means the neural signals direct […]

Gene Linking Brain Structure to Intelligence Identified

February 12, 2014

1 Comment

An international team of scientists has identified a gene linking brain structure to intelligence, finding that teenagers carrying a particular gene variant had a thinner cortex in the left cerebral hemisphere and performed less well on tests for intellectual ability. For the first time, scientists at King’s College London have identified a gene linking the […]
