Brain Research: Nano-tools for deep brain stimulation ♦ First glimpse of new concepts developing in the brain ♦'Alzheimer's protein' plays role in maintaining eye health,

Scientists gain first glimpse of new concepts developing in the brain Scientists have documented the formation of a newly learned concept inside the brain and show that it occurs in the same brain areas for everyone. The results from this study also indicate that it may be possible to use a similar approach to understand the 'loss' of knowledge in various brain disorders, such as dementia or Alzheimer's disease, or due to brain injuries.
U.S. space program researchers develop potential nano-tools for deep brain stimulation The ability of a carbon nanofiber pad to detect changing neurotransmitter concentrations was demonstrated in a proof-of-principle collaboration between engineers and neurosurgeons. The active area was one-tenth the size of current deep-brain-stimulation electrical contacts.
Weekly non-invasive brain stimulation provides long-term relief of post-stroke pain Weekly sessions of non-invasive repetitive transcranial magnetic stimulation provided sufficient long-term pain relief in 61 percent of patients with central post-stroke pain, and delivered long-term relief for patients who continued for one year
'Alzheimer's protein' plays role in maintaining eye health, muscle strength Amyloid precursor protein (APP), a key protein implicated in the development Alzheimer's disease, may play an important role in eye and muscle health. In a new report, scientists say they have discovered that when proteins that bind to the APP, called FE65 and FE65L1, are deleted, they cause cataracts and muscle weakness in mice.
Researchers isolate smallest unit of sleep to date Scientists have grown a tiny group of brain cells that can be induced to fall asleep, wake up and even show rebound sleep after 'staying up late.' The study opens the door to deeper understanding of the genetic, molecular and electrical aspects underlying sleep disorders
