Heavy drinking may reinforce itself by stimulating endorphin release: Study

A new study has shown that drinking alcohol causes a pleasant feeling because it releases endorphins, the brain’s natural opioids. It adds that problem drinkers differ from social drinkers in the way alcohol affects one part of the brain. The report appeared Wednesday in Science Translational Medicine.

Drinking alcohol leads to release of endorphins in the brain

Drinking alcohol leads to the release of endorphins in areas of the brain that produce feelings of pleasure and reward, according to a study led by researchers at the Ernest Gallo Clinic and Research Center at the University of California, San Francisco.

Scientists investigate specific role of IT neurons in 3D perception

The incredible ability of our brain to create a three-dimensional (3D) representation from an object's two-dimensional projection on the retina is something that we may take for granted, but the process is not well understood and is likely to be highly complex. Now, new research published by Cell Press in the January 12 issue of the journal Neuron provides the first direct evidence that specific brain areas underlie perception of different 3D structures and sheds light the way that the primate brain reconstructs real-world objects.

Scientists map neurons that process different kinds of visual information

There's a 3-D world in our brains. It's a landscape that mimics the outside world, where the objects we see exist as collections of neural circuits and electrical impulses.

FDG-PET safe and accurate in detecting dementia, Alzheimer's

In a new review of imaging studies spanning more than ten years, scientists find that a method of positron emission tomography (PET) safely and accurately detects dementia, including the most common and devastating form among the elderly, Alzheimer's disease.

Research reveals how bats parse duties at single neuron level

Imagine listening to music while carrying on a conversation with friends. This type of multi-tasking is fairly easy to do, right? That's because our brains efficiently and effectively separate the auditory signals - music to the right side; conversation to the left. But what researchers have not been able to do in humans or animals is to see a parsing of duties at the single neuron level - until now.

Marijuana ingredients appear to affect regional brain function during salience processing

Different ingredients in marijuana appear to affect regions of the brain differently during brain processing functions involving responses to certain visual stimuli and tasks, according to a report in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals.

Glia cells also regulate learning and memory

Glia cells, named for the Greek word for "glue," hold the brain's neurons together and protect the cells that determine our thoughts and behaviors, but scientists have long puzzled over their prominence in the activities of the brain dedicated to learning and memory.

Early Alzheimer’s detection - cost effective and easy

Boston researchers have reported a new method for detecting subtle brain changes in people who have no memory problems but who may already be in the earliest stages of Alzheimer’s disease.

Scientists model brain structure to help computers recognize objects

An essential question confronting neuroscientists and computer vision researchers alike is how objects can beidentified by simply "looking" at an image. Introspectively, we know that the human brain solves this problem very well. We only have to look at something to know what it is.

People with smaller regions of brain's cortex more likely to develop early Alzheimer's

New research suggests that, in people who don't currently have memory problems, those with smaller regions of the brain's cortex may be more likely to develop symptoms consistent with very early Alzheimer's disease.

Kessler Foundation researcher earns Humboldt award for brain and behavior study

Jordan Grafman, PhD, director of traumatic brain injury research at Kessler Foundation, has received a Humboldt Research Award from the Alexander von Humboldt Foundation. This prestigious award encourages collaborative research between German scientists and renowned investigators like Dr. Grafman, who specializes in the study of the human prefrontal cortex and cognitive neuroplasticity.

Researchers identify genetic factors responsible for neurons in the thalamus

The thalamus is the central translator in the brain: Specialized nerve cells (neurons) receive information from the sensory organs, process it, and transmit it deep into the brain. Researchers from the Institute of Toxicology and Genetics (ITG) of KIT have now identified the genetic factors Lhx2 and Lhx9 responsible for the development of these neurons.

Acetylcholine can weaken synaptic connections between neurons in brain

Researchers from the University of Bristol have discovered that a chemical compound in the brain can weaken the synaptic connections between neurons in a region of the brain important for the formation of long-term memories.

New method for detailed analyses of electrical activity in brain

Researchers at the Norwegian University of Life Sciences (UMB) and Forschungszentrum J-lich in Germany have developed a new method for detailed analyses of electrical activity in the brain.

Cortex plays a key role in fear learning

The study, initiated by the Swiss researchers and published in Nature, constitutes ground-breaking work in exploring emotions in the brain.

MS may progress from outermost layers of brain to its deep parts

Multiple sclerosis (MS) may progress from the outermost layers of the brain to its deep parts, and isn't always an "inside-out" process as previously thought, reported a new collaborative study from researchers at the Mayo Clinic and the Cleveland Clinic.

Visual cortex cells play a key role in reconstructing 3D shape

As dizzying as it may sound, the impression that we are living in a 3D world is actually a continuous fabrication of our brains. When we look at things, the world gets projected onto the retina and information about the third dimension is lost - a bit like when a 3D object casts a shadow onto a flat, 2D wall. Somehow the brain is able to reconstruct the third dimension from the image, allowing us to experience a convincing 3D world.

First realistic 3-D diagram of thalamocortical column in rodent brain

Researchers from the lab of Nobel laureate Bert Sakmann, MD, PhD at the Max Planck Florida Institute (MPFI) are reporting that, using a conceptually new approach and state-of-the-art research tools, they have created the first realistic three-dimensional diagram of a thalamocortical column in the rodent brain.

Researchers identify brain area that controls voluntary movement after damage

Researchers have identified the area of the brain that controls our ability to correct our movement after we've been hit or bumped -- a finding that may have implications for understanding why subjects with stroke often have severe difficulties moving.
