Brain Cell Communication: Why It’s so Fast Researchers have been studying the complex organic protein complexes that link vesicles and membranes prior to fusion, in order to find an explanation for the rapidity of transmissions. They have discovered that the vesicle contains no fewer than three copies of the linking bridge or “SNARE complex”. [Press release from the University of Copenhagen discussing online prepublication in Science] Rescue Services at the Cellular Level: How Stem Cells Help the Brain to Regain its Functions After a Stroke A study has now demonstrated, in a long-term animal study on rats, that the positive effect of stem cell injection after a stroke is mainly based on a stimulative effect in the surrounding cell region. [Press release from the Max Planck Institute for Neurological Research in Cologne discussing online prepublication in PLoS ONE] Genetic Cause for Migraine Found The study found that if the gene known as TRESK does not work properly, it can more easily trigger sensitive pain centres in the brain and cause a severe headache. [Press release from the Medical Research Council discussing online prepublication in Nature Medicine] Brain Naturally Learns to Recognize Objects To test “temporal contiguity,” researchers “tricked” monkeys by exposing them to an altered visual world in which the normal rules of temporal contiguity did not apply. They recorded electrical activity from individual neurons in a region of the monkey brain called the inferior temporal cortex, where object recognition is thought to happen. [Press release from MIT’s McGovern Institute for Brain Research discussing online prepublication in Neuron] Queen’s Researchers Locate Impulse Control Centre in the Brain Impulsive behaviour can be improved with training and the improvement is marked by specific brain changes, according to a new study. [Press release from Queen’s University discussing online prepublication in the Journal of Neuroscience] Breakthrough in Understanding Brain Function Could Lead to Alzheimer’s Treatment Neuroscientists have discovered a new form of synaptic interaction in the brain involved in memory function which could open up the possibility of a new treatment for Alzheimer’s disease. [Press release from the University of Bristol discussing online prepublication in Nature Neuroscience] Key Action of a Gene Linked to Both Alzheimer’s Disease and Type 2 Diabetes Identified A research team has identified the mechanism behind a single gene linked to the causes of both Alzheimer’s disease and Type 2 diabetes. [Press release from ScienceDaily discussing online prepublication in the Journal of Neuroscience] Sodium Plays Key Role in Tissue Regeneration: New Drug Treatment Triggers Sodium Ions to Regrow Nerves and Muscle; Could Extend Treatment Window for Acute Injuries Biologists have discovered that sodium plays a key role in initiating a regenerative response after severe injury. Scientists have found a way to regenerate injured spinal cord and muscle by using small molecule drugs to trigger an influx of sodium ions into injured cells.

CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal) Fast Vesicle Fusion in Living Cells Requires at Least Three SNARE Complexes Fast fusion typically observed in synapses and neurosecretory cells requires at least three functional SNARE complexes, while slower release might occur with fewer. [Science] Channel-Mediated Tonic GABA Release from Glia Although phasic GABA release arises from Ca2+-dependent exocytosis from neurons, the mechanism of tonic GABA release is unclear. Here researchers report that tonic inhibition in the cerebellum is due to GABA’s release from glial cells by permeation through the Bestrophin 1 anion channel. [Science] A Dominant-Negative Mutation in the TRESK Potassium Channel is Linked to Familial Migraine with Aura Here researchers report a frameshift mutation, F139WfsX24, which segregates perfectly with typical migraine with aura in a large pedigree. [Nat Med] Unsupervised Natural Visual Experience Rapidly Reshapes Size-Invariant Object Representation in Inferior Temporal Cortex We easily recognize objects and faces across a myriad of retinal images produced by each object. One hypothesis is that this tolerance (a.k.a. “invariance”) is learned by relying on the fact that object identities are temporally stable. While researchers previously found neuronal evidence supporting this idea at the top of the nonhuman primate ventral visual stream (inferior temporal cortex, researchers here test if this is a general tolerance learning mechanism. [Neuron] SOX9 Induces and Maintains Neural Stem Cells Data identifies a functional link between extrinsic and intrinsic mechanisms of neural stem cell specification and maintenance, and establish a central role for SOX9 in the process. [Nat Neurosci] Muscarinic Receptors Induce LTD of NMDAR EPSCs via a Mechanism Involving Hippocalcin, AP2 and PSD-95 Researchers found that stimulation of muscarinic receptors, either by an agonist or by the synaptic release of acetylcholine, led to long-term depression (LTD) of NMDAR-mediated synaptic transmission. [Nat Neurosci] Target-Specific Encoding of Response Inhibition: Increased Contribution of AMPA to NMDA Receptors at Excitatory Synapses in the Prefrontal Cortex Researchers suggest that response inhibition is encoded by a selective strengthening of a subset of corticostriatal projections, uncovering a synaptic mechanism of impulse control. This information could be exploited in therapeutic interventions for disorders of impulse control, such as addiction, attention deficit-hyperactivity disorder, and schizophrenia. [J Neurosci] Diabetes-Associated SorCS1 Regulates Alzheimer’s Amyloid-Beta Metabolism: Evidence for Involvement of SorL1 and the Retromer Complex Researchers have undertaken a study of the possible role(s) for SorCS1 in metabolism of the Alzheimer’s amyloid-beta peptide (Abeta) and the Abeta precursor protein, to test the hypothesis that Sorcs1 deficiency might be a common genetic risk factor underlying the predisposition to Alzheimer’s disease that is associated with type 2 diabetes mellitus. [J Neurosci] Induction of Vertebrate Regeneration by a Transient Sodium Current Whereas voltage-gated sodium channels play a well known and important role in propagating action potentials in excitable cells, researchers have identified a novel role in regeneration for the ion transport function mediated by the voltage-gated sodium channel, NaV1.2. [J Neurosci] Stem Cell Mediation of Functional Recovery after Stroke in the Rat In order to address the underlying mechanisms of stem cell mediated functional improvement, this functional improvement after stroke in the rat was investigated for six months after stroke by use of fMRI, somatosensory evoked potentials by electrophysiology, and sensorimotor behavior testing.
