The secret lives (and deaths) of neurons
May 23, 2013 | University of North Carolina at Chapel Hill
UNC Neuroscience Center As the human body fine-tunes its neurological wiring, nerve cells often must fix a faulty connection
by amputating an axon — the “business end” of the neuron that sends electrical impulses to tissues or other neurons. It is
a dance with death, however, because the molecular poison the neuron deploys to sever an axon could, if uncontained, kill
the entire cell.

Study Points to Possible Cause of, and Treatment for, Non-familial Parkinson’s
February 7, 2013 | Columbia University
Columbia University Medical Center (CUMC) researchers have identified a protein trafficking defect within brain cells that
may underlie common non-familial forms of Parkinson’s disease. The defect is at a point of convergence for the action of at
least three different genes that had been implicated in prior studies of Parkinson’s disease. Whereas most molecular studies
focus on mutations associated with rare familial forms of the disease, these findings relate directly to the common non-familial
form of Parkinson’s. The study was published today in the online edition of the journal Neuron.
Brain research provides clues to what makes people think and behave differently
February 6, 2013 | Massachusetts General Hospital

neurologists think about brain injury in the pre-term infant. In a study published online in the Jan. 16 issue of Science
Translational Medicine, the OHSU Doernbecher researchers report for the first time that low blood and oxygen flow to the developing
brain does not, as previously thought, cause an irreversible loss of brain cells, but rather disrupts the cells’ ability to
fully mature. This discovery opens up new avenues for potential therapies to promote regeneration and repair of the premature
Study finds a new culprit for epileptic seizures
January 15, 2013 | Massachusetts Institute of Technology
Epileptic seizures occur when neurons in the brain become excessively active. However, a new study from MIT neuroscientists

Scripps Florida Scientists Uncover Potential Drug Target to Block Cell Death in Parkinson’s Disease
January 10, 2013 | Scripps Research
Oxidative stress is a primary villain in a host of diseases that range from cancer and heart failure to Alzheimer’s disease,
Amyotrophic Lateral Sclerosis and Parkinson’s disease. Now, scientists from the Florida campus of The Scripps Research Institute
(TSRI) have found that blocking the interaction of a critical enzyme may counteract the destruction of neurons associated
with these neurodegenerative diseases, suggesting a potential new target for drug development.
Newly Found "Volume Control" in the Brain Promotes Learning, Memory
January 9, 2013 | Georgetown University
Scientists have long wondered how nerve cell activity in the brain’s hippocampus, the epicenter for learning and memory, is
controlled — too much synaptic communication between neurons can trigger a seizure, and too little impairs information processing,
promoting neurodegeneration. Researchers at Georgetown University Medical Center say they now have an answer. In the January
10 issue of Neuron, they report that synapses that link two different groups of nerve cells in the hippocampus serve as a
kind of "volume control," keeping neuronal activity throughout that region at a steady, optimal level.

consequences of traumatic brain injury (TBI) using rat models, have found that, overtime, TBI results in progressive brain
deterioration characterized by elevated inflammation and suppressed cell regeneration. However, therapeutic intervention,
even in the chronic stage of TBI, may still help prevent cell death.
Study Refutes Accepted Model of Memory Formation
January 2, 2013 | Johns Hopkins
A study by Johns Hopkins researchers has shown that a widely accepted model of long-term memory formation — that it hinges
on a single enzyme in the brain — is flawed. The new study, published in the Jan. 2 issue of Nature, found that mice lacking
the enzyme that purportedly builds memory were in fact still able to form long-term memories as well as normal mice could.
Itchy Wool Sweaters Explained
January 2, 2013 | Johns Hopkins
Johns Hopkins researchers have uncovered strong evidence that mice have a specific set of nerve cells that signal itch but
not pain, a finding that may settle a decades-long debate about these sensations, and, if confirmed in humans, help in developing
treatments for chronic itch, including itch caused by life-saving medications.
TOPMRI Can Screen Patients for Alzheimer's Disease or Frontotemporal Lobar Degeneration, Using Penn-designed Model
December 26, 2012 | University of Pennsylvania
When trying to determine the root cause of a person's dementia, using an MRI can effectively and non-invasively screen patients
for Alzheimer's disease or Frontotemporal Lobar Degeneration (FTLD), according to a new study by researchers from the Perelman
School of Medicine at the University of Pennsylvania. Using an MRI-based algorithm effectively differentiated cases 75 percent
of the time, according to the study, published in the December 26th, 2012, issue of Neurology, the medical journal of the

fibers and is essential for normal brain function.
Benjamin Warf earns MacArthur award for Hydrocephalus Research
October 2, 2012 | YouTube
Dr. Benjamin Warf has received a MacArthur Award for his contributions to hydrocephalus research. Hydrocephalus is caused
by a buildup of cerebrospinal fluid (CSF) in brain spaces called ventricles. It is commonly treated with a shunt – a device
to drain the CSF – but over time, the shunt can fail. Dr. Warf has developed an alternative procedure that involves threading
a tube into the ventricles; the tube is then used to create a small drainage hole and to cauterize some of the tissue that

the adult central nervous system (CNS).
How early social deprivation impairs long-term cognitive function
September 13, 2012 | Children’s Hospital Boston
A growing body of research shows that children who suffer severe neglect and social isolation have cognitive and social impairments
as adults. A study from Boston Children’s Hospital shows, for the first time, how these functional impairments arise: Social
isolation during early life prevents the cells that make up the brain’s white matter from maturing and producing the right
amount of myelin, the fatty “insulation” on nerve fibers that helps them transmit long-distance messages within the brain.
