Frontiers in Anatomy has just released the first brown bear’s brain atlas, derived from cross-sectional and magnetic resonance imaging. Agnieszka Sergiel is one of the authors of this paper. Most of the neuroanatomical analyses conducted so far have focused on sulci and gyri patterns in various Carnivora families. The paper shows e.g. that the brain of Ursus arctos is more convoluted than in the cat, the dog and Mustelidae but less than in Pinnipedia.
