Researchers Clock the Speed of Brain Signals
Two studies 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. [Press release from Weill Cornell Medical College discussing online prepublication in Nature Neuroscience and Neuron]

To Fix Diabetic Nerve Damage, Blood Vessels and Support Cells May Be the Real Targets of Treatment, Hopkins Study Suggests
Blood vessels and supporting cells appear to be pivotal partners in repairing nerves ravaged by diabetic neuropathy, and nurturing their partnership with nerve cells might make the difference between success and failure in experimental efforts to regrow damaged nerves. [Press release from John Hopkins University School of Medicine discussing online prepublication in Brain]

Researchers Identify Compound That May Provide Drug Therapy Approach for Huntington’s Disease
Researchers have identified compounds that appear to inhibit a signaling pathway in Huntington’s disease, a finding that may eventually lead to a potential drug therapy to help slow the progression of degenerative nerve disorders. [Press release from The University of Texas Southwestern Medical Center, Dallas discussing online prepublication in Chemistry and Biology]

Competition Between Brain Cells Spurs Memory Circuit Development
Scientists have for the first time demonstrated how memory circuits in the brain refine themselves in a living organism through two distinct types of competition between cells. [Press release from the University of Michigan discussing online prepublication in Neuron]

Nanotubes to the Rescue: Brain Cells Rescued by Gene Silencing Offers New Options for Stroke
The use of carbon nanotubes to deliver short strands of RNA and induce gene silencing of specific target areas in the brain responsible for motor functions has allowed scientists to ‘switch off’ proteins that contribute to neuronal tissue loss. [Press release from The School of Pharmacy, University of London discussing online prepublication in the Proceedings of the National Academy of Sciences USA]

Sight Requires Exact Pattern of Neural Activity to be Wired in the Womb
The precise wiring of our visual system depends upon the pattern of spontaneous activity within the brain that occurs well before birth, a new study shows. [Press release from Yale University discussing online prepublication in Neuron]

Non-coding RNA Has Role in Inherited Neurological Disorder – And Maybe Other Brain Diseases Too
A team of scientists have uncovered a novel mechanism regulating gene expression and transcription linked to Spinocerebellar ataxia 7. [Press release from the University of California, San Diego discussing online prepublication in Neuron]

HIV Disrupts Blood-Brain Barrier
HIV weakens the blood-brain barrier by overtaking a small group of supporting brain cells. [Press release from the Society for Neuroscience discussing online prepublication in The Journal of Neuroscience]

Lithium Profoundly Prevents Brain Damage Associated with Parkinson’s Disease
Lithium profoundly prevents the aggregation of toxic proteins and cell loss associated with Parkinson’s disease in a mouse model of the condition. [Press release from the Buck Institute discussing online prepublication in the Journal of Neuroscience Research]


CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)

Multiple Forms of Activity-Dependent Competition Refine Hippocampal Circuits In Vivo
Using a mouse genetic system in which restricted populations of neurons in the hippocampal circuit are inactivated, researchers show that inactive axons are eliminated after they develop through a competition with active axons. [Neuron]

An Instructive Role for Patterned Spontaneous Retinal Activity in Mouse Visual Map Development
Researchers manipulated the pattern of spontaneous retinal waves present during development without changing overall activity levels through the transgenic expression of β2-nicotinic acetylcholine receptors in retinal ganglion cells of mice. [Neuron]

CTCF Regulates Ataxin-7 Expression through Promotion of a Convergently Transcribed, Antisense Noncoding RNA
To understand how CTCF regulates ataxin-7 gene expression, researchers introduced ataxin-7 mini-genes into mice, and found that CTCF is required for SCAANT1 expression. [Neuron]

Overlapping Role of Dynamin Isoforms in Synaptic Vesicle Endocytosis
Researchers show that dynamin 3, thought to play a predominantly postsynaptic role, has a major presynaptic function. [Neuron]

Neuron-Restrictive Silencer Factor-Mediated Cyclic Nucleotide Gated Channelopathy in Experimental Temporal Lobe Epilepsy
Enduring, abnormal expression and function of the ion channel hyperpolarization-activated cyclic-AMP gated channel type 1 occurs in temporal lobe epilepsy. Researchers examined the underlying mechanisms, and queried if interfering with these mechanisms could modify disease course. [Ann Neurol]

Functional Motor Recovery from Brain Ischemic Insult by Carbon Nanotube-Mediated siRNA Silencing
Here, researchers studied whether silencing of Caspase-3 using carbon nanotube-mediated in vivo RNA interference could offer a therapeutic opportunity against stroke. [Proc Natl Acad Sci USA]

Boundary Cap Cells Are Peripheral Nervous System Stem Cells That Can Be Redirected into Central Nervous System Lineages
Researchers show that boundary cap cell progeny are EGF/FGF2-responsive, form spheres, and express neural crest markers. [Proc Natl Acad Sci USA]

Impaired Neurovascular Repair in Subjects with Diabetes Following Experimental Intracutaneous Axotomy
Researchers examined blood vessel, Schwann cell and axonal regeneration using validated axotomy models to study and compare patterns and the relationship of regeneration among these different structures. [Brain]

Human Immunodeficiency Virus Infection of Human Astrocytes Disrupts Blood–Brain Barrier Integrity by a Gap Junction-Dependent Mechanism
Here, researchers demonstrate that few HIV-infected astrocytes (4.7 ± 2.8% in vitro and 8.2 ± 3.9% in vivo) compromise blood–brain barrier integrity. [J Neurosci]

Neuronal Store-Operated Calcium Entry Pathway as a Novel Therapeutic Target for Huntington’s Disease Treatment
Researchers found that the store-operated calcium entry (SOC) pathway activity is enhanced in neuronal cells expressing mutant Huntingtin and that the identified compounds inhibit SOC pathway in Huntington’s disease neurons. [Chem Biol]

Lithium Protects Against Oxidative Stress-Mediated Cell Death in α-Synuclein-Overexpressing In Vitro and In Vivo Models of Parkinson’s Disease
In this study, researchers examined the potential cytoprotective effect of lithium in preventing oxidative stress-induced protein accumulation and neuronal cell death in the presence of increased α-synuclein levels in vitro and in vivo. [J Neurosci Res]
