Hunched Over a Microscope, Santiago Ramon y Cajal Sketched the Secrets of How the Brain Works



Last month, the Weisman Art Museum in Minneapolis opened a traveling exhibit that is the first dedicated solely to Ramón y Cajal’s work. According to a New York Times article, it will make stops in Minneapolis; Vancouver, British Columbia; New York City; Cambridge, Mass.; and Chapel Hill, N.C., through April 2019.

Best Post of November 2016: Calcifying Pseudoneoplasm of the Neuroaxis (CAPNON)


The next in our "Best of the Month" series is from November 11, 2016:

Approximately 59 cases of CAPNON have been reported in the literature, A non-neoplastic entity that can be found in either an intra-axial or extra-axial location, the pathogenesis of CAPNON is unclear but a reactive process has been favored. The outcome is generally considered to be excellent, with gross total resection typically curative. This case is somewhat unique in that it harbors adipose tissue.

Foci of calcification and fat are present in this midline example


Nodules of basophilic calcification


The calcifications have a chondromyxoid appearance


Surgery was complicated as the lesion encased the anterior cerebral arteries
