Brain imaging studies of women with breast cancer before and after chemotherapy treatments show grey matter is being affected during the chemotherapy treatments. Brain areas believed to be critical for multi-tasking, memory and other cognitive functions were seen to change during the chemotherapy.
Neuroscientists at UC Berkeley have discovered that stimulation of a certain area of the brain can cause a change in which hand a person favors to perform a task. Using transcranial magnetic stimulation on right handed test subjects, researchers discovered that stimulating the posterior parietal cortex on the left side caused an increase in the use of the left hand. Researchers suggested this finding might be useful in discovering methods to help patients overcome learned limb disuse.
Correlating data from 588 patients diagnosed with frontotemporal lobe degeneration (FTLD), researchers found that subjects with professions which related highly for verbal skills had greater tissue loss on the right hand side of the brain. By contrast, those whose professions required less aptitude for verbal skills, for example flight engineers, had more tissue damage to the left hand side of the brain.
Neuroscientists have identified an area within the brain which controls impulsive behavior and have discovered the mechanisms that affect how impulsive behavior is learned. Training rats to control impulsive responses, neuroscientists discovered electrical signals between cells in the frontal lobe grew stronger when impulses were controlled. These findings could eventually help to help diagnose and treat impulse behavior problems such as addiction, obsessive compulsive disorder and ADHD.
Neuralstem has released a new report detailing positive results for stem cell treatments. Initial findings show that not only do implanted human spinal cord-derived stem cells survive, but also differentiate into neurons in rats brains affected by strokes. This finding could potentially provide new therapies for treating strokes.
Neuroscience researchers have identified a new molecular pathway underlying Parkinson's disease. The pathway involves polyamines, which were discovered to be responsible for increased build-up of other toxic proteins in neurons. The research also suggests polyamine lowering drugs could have a protective effect from Parkinson's disease.
Neuroscience researchers are investigating axon clusters in order to develop a "brain atlas". The research could provide a way for clinicians to recognize groups of abnormal axon clusters. When systematically arranged into the "brain atlas", abnormal axon clusters could be used as bio-markers to diagnose neurological disorders.
Neurologists have established new guidelines for the diagnosis and treatment of infantile spasms. Infantile spasms is a rare epileptic disorder which typically affects children under the of age 8 months.
Researchers have discovered the brain enters and leaves states of anesthetic-induced unconsciousness through different processes. The study suggests both forward and reverse paths through which induced unconsciousness dissipates and arrives are not identical. Noted was a delay in returning to a state of consciousness even after levels of anesthetic diminish.
Researchers at the UTMB, Galveston are calling for traumatic brain injury to be defined and managed as a chronic disease.
New research points to a DNA sequence that causes the DUX4 gene to become more active in producing proteins that are toxic to muscle cells, leading to a form of muscular dystrophy.
