Sex‐specific lateralization during aggressive interactions in breeding king penguins
Abstract Brain and behavioral asymmetries (termed "lateralization"; e.g., preferential eye‐use) have been mostly described in controlled laboratory conditions, although striking similarities of hemispheric brain control for specific behaviors have also been shown in the wild. Visual latera...
