Brain navigation can occur without external cues

A discovery at Queensland Brain Institute (QBI) has identified how little information the brain needs in order to navigate and accurately estimate location.

QBI research has led to the development of a startling theory that animal brains can use a memory map to determine locations without external cues such as sight, smell, touch and sound.

Dr Allen Cheung said that until now is has been incorrectly assumed that external input is needed for navigation within any environment.

High Prevalence of Vitamin D Deficiency Across the Board in Neuromuscular Disease

A study presented at the annual meeting of the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) adds more credence to a growing awareness of the high prevalence of vitamin D deficiency in neuromuscular disease.

"Previous work has shown vitamin D deficiency to be quite common in other neurological disorders such as multiple sclerosis, myasthenia gravis, and Parkinson's disease. This study suggests this concern may be more prevalent in other neuromuscular conditions as well," said Ileana Howard, MD, AANEM News Science Editorial Board member.
