Coffee, other stimulant drugs may cause high achievers to slack off: research
(Medical Xpress) — While stimulants may improve unengaged workers performance, a new University of British Columbia study suggests that for others, caffeine and amphetamines can have the opposite effect, causing workers with higher motivation levels to slack off.
Guideline: IVIg effective for certain nerve and muscle disorders
Intravenous immune globulin (IVIg) is an effective treatment for certain disorders of the nerve and muscles, including Guillain-Barré syndrome (GBS) and a form of neuropathy called chronic inflammatory demyelinating polyneuropathy (CIDP), according to a guideline issued by the American Academy of Neurology. The guideline is published in the March 27, 2012, print issue of Neurology, the medical journal of the American Academy of Neurology.
Highly flexible despite hard-wiring — even slight stimuli change the information flow in the brain
One cup or two faces? What we believe we see in one of the most famous optical illusions changes in a split second; and so does the path that the information takes in the brain. In a new theoretical study, scientists of the Max Planck Institute for Dynamics and Self-Organization, the Bernstein Center Göttingen and the German Primate Center now show how this is possible without changing the cellular links of the network. The direction of information flow changes, depending on the time pattern of communication between brain areas. This reorganisation can be triggered even by a slight stimulus, such as a scent or sound, at the right time.
Researchers show that memories reside in specific brain cells
Our fond or fearful memories that first kiss or a bump in the night leave memory traces that we may conjure up in the remembrance of things past, complete with time, place and all the sensations of the experience. Neuroscientists call these traces memory engrams.
