In the recessive deafness model, gene therapy with TMC1 restored the ability of sensory hair cells to respond to sound--producing a measurable electrical current--and also restored activity in the auditory portion of the brainstem.
In the dominant deafness model, gene therapy with a related gene, TMC2, was successful at the cellular and brain level,

A major stumbling block in these efforts however is finding a way to do this without disturbing vital processes in the brain
and Naoyuki Taniguchi at RIKEN in collaboration with Tamao Endo and Shigeo Murayama at the Tokyo Metropolitan Institute of Gerontology showed that much of the BACE1 found in the brains of Alzheimer's disease patients is modified by the attachment of a particular sugar with the help of the enzyme
Hypothesizing that preventing this process would relieve Alzheimer's symptoms the researchers crossed mice that lacked Gnt-III with others that express human APP in the brain.
While knocking out Gnt-III is feasible in mice a drug that inhibits Gnt-III in the brain has the potential to be an effective treatment for reducing A?

#Tracking subtle brain mutations systematically Described in the January 7th issue of Neuron, the technique uses"deep,
one of several kinds of so-called somatic mutations that can arise as the brain develops.
The technique picks up somatic mutations that affect just a fraction of the brain's cells, in a"mosaic"pattern.
"showing when during brain development the mutations arise and how they spread through brain tissue as the mutated cells grow,
replicate and migrate, carrying the mutation with them.""There is a lot of genetic diversity from one neuron to the other,
and this work gets at how somatic mutations are distributed in the brain, "says Christopher Walsh, MD, Phd, chief of Genetics and Genomics at Boston Children's and co-senior author on the paper."
"Some mutations may occur on one side of the brain and not the other. Some may be clumped,'affecting just one gyrus fold of the brain,
disrupting just a little part of the cortex at a time.""The study examined brain tissue from a deceased 17-year-old who had been neurologically normal,

#Study pinpoints autism-linked protein for sculpting brain connections A new study by Duke researchers provides a close up of synapse refinement
and suicide but the molecule's role in the developing brain was mostly unknown until now.
But this study which appeared early online last month in the open access journal elife shows that in the brains of newborn mice some of the spines initially receive two or more inputs.
As the brain matures the spines then receive one. A technique known as three-dimensional electron microscopy made this observation possible.
As the developing brain prunes away synapses to become more efficient this could present problems.
That was the first description of hevin's function in the nervous system said Eroglu an assistant professor of cell biology and neurobiology and a member of the Duke Institute for Brain sciences.
because it is abundant in many brain regions both when synapses are forming and also during adulthood Eroglu said.
In the cortex an area of the brain important for complex thought and awareness hevin encourages inputs from the thalamus--a part of the brain that acts as a relay center for sensory and motor information
--while it discourages inputs from local neurons within the cortex the group found. The spines that receive multiple synapses tend to be occupied by both cortical and thalamic connections at the same time suggesting that these spines are sites for synaptic competition.
and other structures of the limbic system located in the temporal lobe when a cascade of molecular and cellular events results in aberrant brain wiring.
The limbic system is the region of the brain associated with memory and emotions. Seizures reflect uncontrolled electrical brain activity.
The period between a brain injury and the onset of seizures called epileptogenesis is a silent period
because this brain abnormality cannot be detected by current neurological exams or electroencephalography (EEG). Temporal lobe epilepsy (TLE) or limbic epilepsy is a common adult epileptic disorder characterized by spontaneous recurrent seizures that may also spread to other brain regions triggering secondary severe generalized seizures.
Aside from neurosurgery which benefits only a small population of TLE patients there are no other effective treatments or preventive strategies.
When they systemically administered Neuroprotectin D-1 (NPD1) the researchers discovered that NPD1 regulated these bursts of brain electrical activity that not only reduced the aberrant brain cell signaling leading to severe generalized seizures but also spontaneous recurrent seizures.
which DHA is released in the brain at the onset of seizures notes Dr. Bazan. Called the Bazan Effect in the literature with the discovery of NDP1 another piece of the puzzle fell into place.
The medial form accounts for almost 80%of all temporal lobe seizures. While medial temporal lobe epilepsy is a very common form of epilepsy it is also frequently resistant to medications.
The overall prognosis for patients with drug-resistant medial temporal lobe epilepsy includes a higher risk for memory and mood difficulties.
This in turn leads to impairments in quality of life and an increased risk for death as observed in patients who have frequent seizures failing to respond to treatment.
These observations will contribute to our ability to predict epileptic events define key modulators of brain circuits especially after a brain injury
and the brain might hold the key to creating therapeutic solutions for blindness stroke and other seemingly unrelated conditions associated with the central nervous system notes Dr. Bazan.
The eye is a window to the brain. Dr. Bazan and his research team discovered Neuroprotectin D1 (NPD1)

The researchers found that the powerful messenger NPD1 is produced on-demand in the brain and retina and that it elicits a network of positive signals essential for the well-being of vision and cognition.

#Brain secrets unlocked by international imaging effort NUI Galway professor of psychology Professor Gary Donohoe led The irish contribution to the study
The study looked at the size of sub-cortical brain regions that are involved in some basic functions such as memory movement learning and motivation.
Abnormalities in these brain regions are associated with neurological and mental health disorders. According to Professor Donohoe: For years scientists have been fascinated by the development of different brain structures and how this changes in brain-based disorders.
In this study we have used MRI scans to look at how the size of different brain regions is influenced by our genes
and obtained some fascinating results. We have found for example one gene variant that affects the size of the Putamen a region near the centre of the brain
which resembles the stone in the middle of a fruit. The Putamen is partly responsible for movement and learning and is implicated in Parkinson's disease.
This finding opens up new avenues for research in this disease by giving new clues about the biological mechanisms involved.
Knowledge about the genetic basis of these structures provides important insights into how the brain develops said Professor Donohoe.
ENIGMA's scientists screen brain scans and genomes worldwide for factors that help or harm the brain said ENGIMA cofounder Professor Paul Thompson from University of Southern California.
This crowdsourcing and sheer wealth of data gives us the power to crack the brain's genetic code.
Unless you know what'normal'development looks like it's hard to know how disease manifests in these sub-cortical regions.
By working together in large collaborative projects we can tackle these types of problems and further our understanding of the biology of the brain.
The study identified five genetic variants that influence the size of structures within the brain.
Of the genetic associations found the largest effect was seen for the Putamen a subcortical region located at the base of the forebrain
In follow up protein expression work this variant was found to alter the expression of KTN1 in frontal cortex.
The study also found evidence of several variants being associated with hippocampal volume (a brain region synonymous with memory encoding and retrieval) one

The ENIGMA researchers screened millions of"spelling differences"in the genetic code to see which ones affected the size of key parts of the brain in magnetic resonance images (MRIS) from 30,717 individuals.
The MRI analysis focused on genetic data from seven regions of the brain that coordinate movement, learning, memory and motivation.
The group identified eight genetic variants associated with decreased brain volume several found in over one-fifth of the world's population.
People who carry one of those eight mutations had, on average, smaller brain regions than brains without a mutation but of comparable age;
