Scientists Use Prosthetic Device to Restore and Improve Impaired Decision Making Ability in Animals

Scientists used an electronic prosthetic system to tap into existing circuitry in the brain at the cellular level and record the firing patterns of multiple neurons in the prefrontal cortex, the part of the brain involved in decision-making. They then “played” that recording back to the same brain area to electrically stimulate decision-based neural activity. Not only did it restore function, in some cases, it also improved it.

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.

Simple Mathematical Computations Underlie Brain Circuits

Neuroscientists report that two major classes of brain cells repress neural activity in specific mathematical ways: One type subtracts from overall activation, while the other divides it.

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.

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.

Study Pinpoints a Genetic Cause of Most Lethal Brain Tumor and May Lead to New Treatment

Researchers discovered that some cases of glioblastoma, the most common and aggressive form of primary brain cancer, are caused by the fusion of two adjacent genes. The study also found that drugs that target the protein produced by this genetic aberration can dramatically slow the growth of glioblastomas in mice.

Cylindrical Cell Structure Parts May Aid in Targeting Diseases Such as Cancer, Alzheimer’s, Parkinson’s

The model of microtubule assembly that most people accept shows the individual subunits, dimers of the protein tubulin, just adding to the grow cylinder. But another model indicates that tubulin dimmers first form an open sheet structure that later closes into the cylinder. Xing and his team concluded that their computational study of the models indicate that the second model should be seriously considered for further testing.

Virtual Reality Allows One to Feel Own Arm is Three to Four Times the Length of Real Arm

A study shows that using virtual reality, an arm up to three or possibly even four times the length of a person’s real arm can be felt as if it was the person’s own arm, even if it incorporates strong asymmetries in the body shape.
