Dear Colleagues,

 

This is to announce the publication of our new paper entitled: Diffusion
Tensor Imaging of Dolphin Brains Reveals Direct Auditory Pathway to Temporal
Lobe published in Proceedings of the Royal Society B.  The free-access paper
is here: http://rspb.royalsocietypublishing.org/content/282/1811/20151203

 

We applied a novel technique known as diffusion tensor imaging (DTI) to the
preserved brains of two dolphins who died after stranding more than a decade
ago. These images revealed that there is more than one auditory primary
cortical region in dolphin brains and that the new area is in the temporal
lobe.  These unprecedented findings show the dolphin brain is more complex
than previously thought and suggest a possible revision of current models of
auditory processing in cetaceans.

Thank you.
