Brain Study Reveals the Roots of Chocolate Temptations

Researchers have new evidence in rats to explain how it is that chocolate candies can be so completely irresistible. The urge to overeat such deliciously sweet and fatty treats traces to an unexpected part of the brain and its production of a natural, opium-like chemical.

Autistic Adults Have Unreliable Neural Responses, Carnegie Mellon-Led Research Team Finds

Neuroscientists take the first step toward deciphering the connection between general brain function and emergent behavioral patterns in autism. Study shows that autistic adults have unreliable neural sensory responses to visual, auditory and somatosensory, or touch, stimuli.

Scientists Show Biological Mechanism Can Trigger Epileptic Seizures

Researchers at Cincinnati Children’s Hospital Medical Center report that molecular disruptions in small neurons called granule cells – located in the dentate gyrus region of the brain – caused brain seizures in mice similar to those seen in human temporal lobe epilepsy.

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.

Brain Neurons and Diet Influence Onset of Obesity and Diabetes in Mice

The absence of a specific type of neuron in the brain can lead to obesity and diabetes in mice report researchers. The outcome, however, depends on the type of diet that the animals are fed.

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.

Toxic Protein Build-up in Blood Shines Light on Fatal Brain Disease

A new light-based technique for measuring levels of the toxic protein that causes Huntington's disease (HD) has been used to demonstrate that the protein builds up gradually in blood cells.

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.

How Early Social Deprivation Impairs Long-Term Cognitive Function

A study shows social isolation during early life prevents the cells that make up the brain's white matter from maturing and producing the right amount of myelin, the fatty "insulation" on nerve fibers that helps them transmit long-distance messages within the brain.

Stress Breaks Loops that Hold Short-Term Memory Together

By watching individual neurons at work, a group of psychologists at the University of Wisconsin-Madison has revealed just how stress can addle the mind, as well as how neurons in the brain's prefrontal cortex help remember information in the first place.

Neural Stem Cells Regenerate Axons in Severe Spinal Cord Injury

Researchers were able to regenerate an astonishing degree of axonal growth at the site of severe spinal cord injury in rats. Results were then replicated using two human stem cell lines, one already in human trials for ALS. “We obtained the exact results using human cells as we had in the rat cells,” said Tuszynski.
