Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

open access: yesThe Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.

Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

open access: yesThe Anatomical Record, EarlyView.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...

Central GABAergic neuromodulation of nocifensive behaviors in bumble bees

open access: yesiScience
Summary: In mammals, nocifensive behaviors are modulated by neuroactive compounds indicating a complex pain-processing system. This study aimed to assess the role of gamma-aminobutyric acid (GABA) in modulating nocifensive behaviors in the bumble bee ...
