Brain Mysteries
Does practice really make perfect? It's an age-old question, and a new study from Rice University, Princeton University and Michigan State University finds that while practice won't make you perfect, it will usually make you better at what you're practicing.

Research from the University of Copenhagen is shedding new light on the brain's complicated barrier tissue. The blood-brain barrier is an effective barrier which protects the brain, but which at the same time makes it difficult to treat diseases such as Alzheimer's. In an in vitro blood-brain barrier, researchers can recreate the brain's transport processes for the benefit of the development of new pharmaceuticals for the brain. The new research findings are published in the AAPS Journal.

 | A new study by researchers at the University of Oregon published today in the journal Neuron describes a brainstem circuit in mice that may help explain how active movement impacts the way the brain processes sensory information. ...> Full Article |
 | Although feelings are personal and subjective, the human brain turns them into a standard code that objectively represents emotions across different senses, situations and even people, reports a new study by Cornell University neuroscientist Adam Anderson. ...> Full Article |
Why does a relentless stream of subjective experiences normally fill your mind? Maybe that's just one of those mysteries that will always elude us. Yet, research from Northwestern University suggests that consciousness lies well within the realm of scientific inquiry -- as impossible as that may currently seem. Although scientists have yet to agree on an objective measure to index consciousness, progress has been made with this agenda in several labs around the world.

Researchers from the universities of Manchester and Liverpool has shown that circuits in the brain involved in pursuing and relishing rewarding experiences are more strongly activated in people with bipolar disorder -- guiding them towards riskier gambles and away from safer ones.
The study by the Universities of Manchester and Liverpool, published today in the journal 'BRAIN', used brain imaging to identify neural pathways that are responsible for the symptoms of the disorder.

A study published in the scientific journal Nature Neuroscience by Yves De Koninck and Robert Bonin, two researchers at Université Laval, reveals that it is possible to relieve pain hypersensitivity using a new method that involves rekindling pain so that it can subsequently be erased. This discovery could lead to novel means to alleviate chronic pain.

Scientists at the Montreal Neurological Institute and Hospital, McGill University and McGill University Health Centre have shown that a member of the protein family known as SUMO -- small ubiquitin-like modifier -- is a key to why tumor cells multiply uncontrollably, especially in the case of glioblastoma.

 | In a new study, Brown University neuroscientists looked cell-by-cell at the brain circuitry that tadpoles, and possibly other animals, use to avoid collisions. The study produced a model of how individual inhibitory and excitatory neurons can work together to control a simple behavior. ...> Full Article |
Spasticity is considered a common reaction after injury, death or apoptosis of central nervous system neurons occur.

 | Twenty-four hours of sleep deprivation can lead to conditions in healthy persons similar to the symptoms of schizophrenia. This discovery was made by researchers under the guidance of the University of Bonn and King's College London. The scientists point out that this effect should be investigated more closely in persons who have to work at night. In addition, sleep deprivation may serve as a model system for the development of drugs to treat psychosis. ...> Full Article |
