Selective activation of the dentate gyrus can reduce anxiety without affecting learning

Columbia University Medical Center (CUMC) researchers have found the first evidence that selective activation of the dentate gyrus, a portion of the hippocampus, can reduce anxiety without affecting learning.

Wayne State receives U.S. patent allowance for vision restoration technology

Technology to restore vision through the use of a component of green algae developed by Dr. Zhou-Han Pan, professor and scientific director of the Ligon Research Center of Vision at the Kresge Eye Institute at Wayne State University, and licensed to RetroSense Therapeutics, a biotechnology company dedicated to developing gene therapy approaches to vision restoration, announced that the U.S. Patent and Trademark Office has issued a Notice of Allowance for U.S. patent application (No. 12/299,574).

Study examines how fear responses are learned, controlled and memorized

A rustle of undergrowth in the outback: it's a sound that might make an animal or person stop sharply and be still, in the anticipation of a predator. That "freezing" is part of the fear response, a reaction to a stimulus in the environment and part of the brain's determination of whether to be afraid of it.

Fifteen established scientists to receive NARSAD Distinguished Investigator Grants

The Brain & Behavior Research Foundation (formerly NARSAD, the National Alliance for Research on Schizophrenia and Depression) announced the latest recipients of its highly competitive NARSAD Distinguished Investigator Grants.

Harvard scientists shed new light on olfactory feedback mechanism

More than a century after it was first identified, Harvard scientists are shedding new light on a little-understood neural feedback mechanism that may play a key role in how the olfactory system works in the brain.

LED light instantly triggers or reverses depression-like behavior in rodents

A specific pattern of neuronal firing in a brain reward circuit instantly rendered mice vulnerable to depression-like behavior induced by acute severe stress, a study supported by the National Institutes of Health has found. When researchers used a high-tech method to mimic the pattern, previously resilient mice instantly succumbed to a depression-like syndrome of social withdrawal and reduced pleasure-seeking - they avoided other animals and lost their sweet tooth.

New fiber-optic device can deliver light to the brain in 3D

A new tool for neuroscientists delivers a thousand pinpricks of light to a chunk of gray matter smaller than a sugar cube. The new fiber-optic device, created by biologists and engineers at the Massachusetts Institute of Technology (MIT) in Cambridge, is the first tool that can deliver precise points of light to a 3-D section of living brain tissue. The work is a step forward for a relatively new but promising technique that uses gene therapy to turn individual brain cells on and off with light.

Brain's infralimbic cortex can switch between new and old habits

Habits are behaviors wired so deeply in our brains that we perform them automatically. This allows you to follow the same route to work every day without thinking about it, liberating your brain to ponder other things, such as what to make for dinner.

Light-sensitive protein to study Parkinson's disease

Introducing a light-sensitive protein in transgenic nerve cells... transplanting nerve cells into the brains of laboratory animals... inserting an optic fibre in the brain and using it to light up the nerve cells and stimulate them into releasing more dopamine to combat Parkinson's disease...

New way to image how brain cells coordinate with each other to control specific behaviors

A team led by MIT neuroscientists has developed a way to monitor how brain cells coordinate with each other to control specific behaviors, such as initiating movement or detecting an odor.

Highlights of Mount Sinai research at Neuroscience 2012

Researchers from Mount Sinai School of Medicine are presenting important discoveries on the involvement of the immune system and dopamine cells in the onset of depression at Neuroscience 2012, the Society for Neuroscience's 42nd annual meeting on October 13 -17 in New Orleans, and are available for interviews.

Researchers discover new group of nerve cells that regulate processes of learning and memory

Swedish researchers at Uppsala University have, together with Brazilian collaborators, discovered a new group of nerve cells that regulate processes of learning and memory. These cells act as gatekeepers and carry a receptor for nicotine, which can explain our ability to remember and sort information.

AAQ chemical temporarily restores vision in blind mice

A team of University of California, Berkeley, scientists in collaboration with researchers at the University of Munich and University of Washington in Seattle has discovered a chemical that temporarily restores some vision to blind mice, and is working on an improved compound that may someday allow people with degenerative blindness to see again.

Automated way to record electrical activity inside neurons in the living brain

Gaining access to the inner workings of a neuron in the living brain offers a wealth of useful information: its patterns of electrical activity, its shape, even a profile of which genes are turned on at a given moment. However, achieving this entry is such a painstaking task that it is considered an art form; it is so difficult to learn that only a small number of labs in the world practice it.

UNC announces recipients of 12th Perl-UNC Neuroscience prize

The University of North Carolina at Chapel Hill has awarded the 12th Perl-UNC Neuroscience prize to Karl Deisseroth, MD, PhD of Stanford University and Edward Boyden, PhD and Feng Zhang, PhD of the Massachusetts Institute of Technology.

Study shows how cocaine changes the shape and size of neuron rewards in mouse model

New research from Mount Sinai Medical Center in New York reveals that repeated exposure to cocaine decreases the activity of a protein necessary for normal functioning of the brain's reward system, thus enhancing the reward for cocaine use, which leads to addiction. Investigators were also able to block the ability of repeated cocaine exposure, to induce addiction.

Paul Allen pledges $300 million to better understand the brain’s inner workings

Microsoft co-founder and billionaire Paul Allen is donating $300 million to his Allen Institute for Brain Science to fund new projects to map and observe the human brain and, in Allen’s words, “to one day understand the essence of what makes us human.” That brings the total amount Allen has invested in the Institute to half a billion.
