Tivey, E. K. L., Martin, J. E., Brown, S. M. et al. 2022. Sex differences in 50 kHz call subtypes emitted during tickling-induced playful behaviour in rats. Scientific Reports 12(1), 15323.

‘Tickling’ induces positive affective states in laboratory rats as evidenced by the production of 50-kHz ultrasonic vocalisations (USVs), although this has mostly been investigated in males. Juvenile rats emit distinctive 50-kHz USV subtypes. Frequency-modulated (FM)...

Allioux, C., Achaintre, L., Cheataini. F. et al. 2022. Animal welfare assessment after severe traumatic brain injury in rats. Laboratory Animals 56(6), 528-539.

Severe traumatic brain injury (TBI) is a multifactorial injury process involving respiratory, cardiovascular and immune functions in addition to the brain. Thus, live animal models are needed to study the molecular, cellular and systemic mechanisms...

Hughey, S., Campbell, D., Rapp-Santos, K. et al. 2022. Refining the rat sciatic nerve block: A novel ultrasound-guided technique. Laboratory Animals 56(2), 191-195.

Murine translational models are an important tool to understand pain pathophysiology. One procedure used frequently in murine research is the sciatic nerve block. This study sought to demonstrate the use of ultrasound-guided sciatic nerve block...
