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.
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.
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.
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.
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 discovered the anterior prefrontal cortex appears to be larger in people with strong introspective abilities. Additionally, the structure of white matter within this area of the brain is also linked to the process of introspection.
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.
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 have provided an insight into the neuronal mechanisms involved in prosocial behavior, and how they are modulated by perceived group membership. Researchers suggest that there is a neurobiological basis of whether people chose to help, or withdraw help, based on positive or negative identification of the person in pain.
