Human Brains Share a Consistent Genetic Blueprint and Possess Enormous Biochemical Complexity

Scientists at the Allen Institute for Brain Science reported that human brains share a consistent genetic blueprint and possess enormous biochemical complexity. The findings stem from the first deep and large-scale analysis of the vast data set publicly available in the Allen Human Brain Atlas.

New Findings on Protein Misfolding

Researchers identified 21 proteins that specifically bind to a protein called ataxin-1. Twelve of these proteins enhance the misfolding of ataxin-1 and thus promote the formation of harmful protein aggregate structures, whereas nine of them prevent the misfolding.

Blue Brain Project Accurately Predicts Connections Between Neurons

Proof of concept: Researchers identify principles to support brain simulation models. Blue Brain Project has identified key principles that determine synapse-scale connectivity by virtually reconstructing a cortical microcircuit and comparing it to a mammalian sample. These principles now make it possible to predict the locations of synapses in the neocortex.

Researchers Identify Potential New Approach for Improving Quality of Life for ALS Patients

By increasing the signaling activity of a protein called muscle skeletal receptor tyrosine-protein kinase (MuSK), researchers were able to keep nerve cells attached to muscle longer into the progression of the disease in a mouse model of ALS.

Astrocytes Control the Generation of New Neurons from Neural Stem Cells

Neuroscience researchers show how astrocytes control the generation of new neurons in the brain. “In the brain, astrocytes control how many new neurons are formed from neural stem cells and survive to integrate into the existing neuronal networks. Astrocytes do this by secreting specific molecules but also by much less understood direct cell-cell interactions with stem cells”, says Prof. Milos Pekny.

First UK Operation to Tackle Heart Failure with Novel Nerve-Stimulating Implant

Researchers announced that the UK’s first operation to tackle heart failure with a novel nerve-stimulating device will be performed today. The implantable device operates by stimulating the vagus nerve on the right side of the neck.

Video Shows the Traffic Inside a Brain Cell

Using bioluminescent proteins from a jellyfish, scientists lit up the inside of a neuron, capturing spectacular video footage that shows the movement of proteins throughout the cell. The video offers a rare peek at how proteins, the brain's building blocks, are directed through neurons to renew its structure.

New Model Synapse Could Shed Light on Disorders Such as Epilepsy and Anxiety

A new way to study the role of a critical neurotransmitter in disorders such as epilepsy, anxiety, insomnia, depression, schizophrenia, and alcohol addiction has been developed. This model synapse can precisely control a variety of receptors for the neurotransmitter called GABA, which is important in brain chemistry.

Researchers Find Genetic Cause for Body Tremors

Scientists knew that mutations in the FUS gene (Fused in Sarcoma) cause amyotrophic lateral sclerosis (ALS), a disease of the nerve cells in the brain and spinal cord that control voluntary muscle movement. The researchers were successful in identifying mutations in this gene that cause Essential Tremor, and proved that the disease mechanisms for ET and ALS FUS mutations are different.

Artificial Butter Flavoring Ingredient Linked to Key Alzheimer’s Disease Process

A new study raises concern about chronic exposure of workers in industry to a food flavoring ingredient used to produce the distinctive buttery flavor and aroma of microwave popcorn, margarines, snack foods, candy, baked goods, pet foods and other products. It found evidence that the ingredient, diacetyl (DA), intensifies the damaging effects of an abnormal brain protein linked to Alzheimer’s disease.

Connectomics: Mapping the Neural Network Governing Male Roundworm Mating

Researchers determined how the neurons and muscles are connected in a decision-making neural network important for mating in C. elegans. The team also accurately measured the weights of those connections, i.e., an estimate of the strength with which one neuron or muscle communicates with another.
