“…We used a pragmatic approach to partition the mesh files using available cortical maps of carnivore brains (Kroenke, Mills, Olavarria, & Neil, 2014; Manger, Engler, Moll, & Engel, 2008; Sereno & Allman, 1991) and also basing our anatomical landmarks on the consistency with which these areas could be partitioned from the cortical surface across carnivore species. Figures 3 and 4 present an overview of our landmark designations and correspondence with the available functional and/or cytoarchitectural maps in the ferret, cat and African wild dog.…”

Over the last 15 years, research on canid cognition has revealed that domestic dogs possess a surprising array of complex sociocognitive skills pointing to the possibility that the domestication process might have uniquely altered their brains; however, we know very little about how evolutionary processes (natural or artificial) might have modified underlying neural structure to support species‐specific behaviors. Evaluating the degree of cortical folding (i.e., gyrification) within canids may prove useful, as this parameter is linked to functional variation of the cerebral cortex. Using quantitative magnetic resonance imaging to investigate the impact of domestication on the canine cortical surface, we compared the gyrification index (GI) in 19 carnivore species, including six wild canid and 13 domestic dog individuals. We also explored correlations between global and local GI with brain mass, cortical thickness, white and gray matter volume and surface area. Our results indicated that GI values for domestic dogs are largely consistent with what would be expected for a canid of their given brain mass, although more variable than that observed in wild canids. We also found that GI in canids is positively correlated with cortical surface area, cortical thickness and total cortical gray matter volumes. While we found no evidence of global differences in GI between domestic and wild canids, certain regional differences in gyrification were observed.

“…In order to be compatible with previous nomenclature for the carnivore brain (for review, see Fuster 2015), the proreal gyrus (PRG) was introduced in the ferret atlas separately, instead of merging this dorsal rostral part of the ferret's FC with the orbital gyrus (OBG) (Nigel et al 1998;Kroenke et al 2014). The PRG constitutes the anterior frontal lobe and mainly corresponds to the dPFC (Radtke-Schuller 2018).…”

Dorsal prefrontal and premotor cortex of the ferret as defined by distinctive patterns of thalamo-cortical projections

Recent studies of the neurobiology of the dorsal frontal cortex (FC) of the ferret have illuminated its key role in the attention network, top-down cognitive control of sensory processing, and goal directed behavior. To elucidate the neuroanatomical regions of the dorsal FC, and delineate the boundary between premotor cortex (PMC) and dorsal prefrontal cortex (dPFC), we placed retrograde tracers in adult ferret dorsal FC anterior to primary motor cortex and analyzed thalamo-cortical connectivity. Cyto-and myeloarchitectural differences across dorsal FC and the distinctive projection patterns from thalamic nuclei, especially from the subnuclei of the medial dorsal (MD) nucleus and the ventral thalamic nuclear group, make it possible to clearly differentiate three separate dorsal FC fields anterior to primary motor cortex: polar dPFC (dPFCpol), dPFC, and PMC. Based on the thalamic connectivity, there is a striking similarity of the ferret's dorsal FC fields with other species. This possible homology opens up new questions for future comparative neuroanatomical and functional studies.
