Tiny brains

January 26, 2014

“It is certain that there may be extraordinary activity with an extremely small absolute mass of nervous matter; thus the wonderfully diversified instincts, mental powers, and affections of ants are notorious, yet their cerebral ganglia are not so large as the quarter of a small pin’s head. Under this point of view, the brain of an ant is one of the most marvellous atoms of matter in the world, perhaps more so than the brain of man.”

Charles Darwin, 1871 AntBrain

The Tango Brain

June 9, 2012

A Matlab animation of brain activation to musical features while listening to a Piazzolla tango. This is work done at my department [Alluri V, Toiviainen P, Jääskeläinen IP, Glerean E, Sams M & Brattico E, Large-scale brain networks emerge from dynamic processing of musical timbre, key and rhythm, NeuroImage (2012)]. And I’m using the same dataset for my thesis to look at working memory activation for the two musical motifs in the piece.
