Researchers discover Foxj1 genetic 'conductor' responsible for new brain cell production

A team of North Carolina State University researchers has discovered more about how a gene connected to the production of new brain cells in adults does its job. Their findings could pave the way to new therapies for brain injury or disease.

Brain stem cells shown to generate multiple new brain stem cells

A Johns Hopkins team has discovered in young adult mice that a lone brain stem cell is capable not only of replacing itself and giving rise to specialized neurons and glia – important types of brain cells – but also of taking a wholly unexpected path: generating two new brain stem cells.

Glia plays key role in preventing progression of Rett Syndrome symptoms

A paper published online today in Nature reveals that glia play a key role in preventing the progression of the most prominent Rett Syndrome symptoms displayed by mouse models of the disease: lethality, irregular breathing and apneas, hypoactivity and decreased dendritic complexity.

Humans experience the Motion Aftereffect even if the motion is brief

Scientists have come up with new insight into the brain processes that cause the following optical illusion: Focus your eyes directly on the "X" in the center of the image in this short video (http://www.youtube.com/watch?v=BXnUckHbPqM&feature=player_embedded)

Rodent olfaction and the chemistry of instinct

The mechanics of instinctive behavior are mysterious. Even something as simple as the question of how a mouse can use its powerful sense of smell to detect and evade predators, including species it has never met before, has been almost totally unknown at the molecular level until now.

Genetic tools that enable cell type-specific delivery hold promise for combating incurable neurologic diseases

Novel tools and methods for delivering therapeutic genes to cells in the central nervous system hold great promise for the development of new treatments to combat incurable neurologic diseases. Five of the most exciting developments in this rapidly advancing field are presented in a series of articles in the June issue of Human Gene Therapy, a peer-reviewed journal published by Mary Ann Liebert, Inc..

Scientists identify central switch responsible for epilepsy

UC Irvine and French researchers have identified a central switch responsible for the transformation of healthy brain cells into epileptic ones, opening the way to both treat and prevent temporal lobe epilepsy.

Cinnamon extract can prevent Alzheimer's

Alzheimer's, the degenerative brain disorder that disrupts memory, thought and behavior, is devastating to both patients and loved ones. According to the Alzheimer's Association, one in eight Americans over the age of 65 suffers from the disease.

McMaster researchers to use tiny worms for Parkinson's project

McMaster researchers from three disciplines are deploying thousands of tiny worms and a homegrown invention to test drugs in a collaborative bid to defeat Parkinson's Disease.

Scientists gain insight into how brains process memory and sense of orientation

How do our brains process memory and sense of orientation? Scientists are gaining insight by studying rats with implanted genes that prompt neurons to fire on command.

Protein globin E helps avian eyes 'breathe' and contributes to visual acuity

Say what you will about bird brains, but our feathered friends sure have us -- and all the other animals on the planet -- beat in the vision department, and that has a bit to do with how their brains develop.

Growth-braking tumor-suppressor gene slows growth of childhood brain tumors

Johns Hopkins researchers have found a likely explanation for the slow growth of the most common childhood brain tumor, pilocytic astrocytoma. Using tests on a new cell-based model of the tumor, they concluded that the initial process of tumor formation switches on a growth-braking tumor-suppressor gene, in a process similar to that seen in skin moles.

New research helps explain how memories are stored at synapses

Have a tough time remembering where you put your keys, learning a new language or recalling names at a cocktail party? New research from the Lisman Laboratory at Brandeis University points to a molecule that is central to the process by which memories are stored in the brain. A paper published in the June 22 issue of the Journal of Neuroscience describes the new findings.

Hunger hormone likely to cause stress-linked complex eating behaviors

We are one step closer to deciphering why some stressed people indulge in chocolate, mashed potatoes, ice cream and other high-calorie, high-fat comfort foods. UT Southwestern Medical Center-led findings, in a mouse study, suggest that ghrelin - the so-called "hunger hormone" - is involved in triggering this reaction to high stress situations.

Oxytocin hormone holds promise for children with Prader-Willi syndrome

Prader-Willi syndrome is a rare genetic disorder which affects one child in 25,000. Children born with this syndrome have a range of complex neurological and developmental problems which continue into adult life. These can manifest as cognitive and behavioral difficulties, weight gain, problems in controlling their temper and attendant difficulties in socialization.

GUMC neuroscientists: Speech perception must have evolved from animals

Neuroscientists at Georgetown University Medical Center (GUMC) have defined, for the first time, three different processing stages that a human brain needs to identify sounds such as speech - and discovered that they are the same as ones identified in non-human primates.

Insights into type I diabetes

A new signal pathway that renders the insulin-releasing beta cell more sensitive to high levels of blood glucose has been discovered by researchers at the Swedish medical university Karolinska Institutet. A second new study reveals a possible way to delay the disease by inhibiting a lipoprotein.

New surprising details about flow of neurotransmitters between brain neurons

Two studies featuring research from Weill Cornell Medical College have uncovered surprising details about the complex process that leads to the flow of neurotransmitters between brain neurons -- a dance of chemical messages so delicate that missteps often lead to neurological dysfunction.
