(Medical Xpress)—In preparation for neuroscience's huge SFN2013 meeting next week in San Diego, many key scientific journals are rolling out their special neuro-focus issues. Generally this is the time for the field to ...
(Medical Xpress) -- Three research teams have published papers in Nature, that together offer evidence suggesting that isocitrate dehydrogenase (IDH) enzyme mutations may play a role in altering activity that could have an ...
A study examining the effect of the immune receptor known as Toll-like Receptor 4, or TLR4, on how memory functions in both the normal and injured brain has found vastly different cellular pathways contribute to the receptor's ...
