Not all ‘predator odours’ are equal: cat odour but not 2,4,5 trimethylthiazoline (TMT; fox odour) elicits specific defensive behaviours in rats
The behavioural responses to two commonly used 'predator odours' were assessed in male Wistar rats. Cat odour was presented to rats in the form of a piece of collar that had been worn by a domesticExpand

Aversive effects of the synthetic cannabinoid CP 55,940 in rats
A series of experiments investigated the behavioral and hedonic effects of the synthetic cannabinoid CP 55,940 in male Wistar rats. CP 55,940 had a biphasic effect on locomotor activity, with a 10Expand

Increased Anxiety 3 Months after Brief Exposure to MDMA (‘Ecstasy’) in Rats: Association with Altered 5-HT Transporter and Receptor Density
Male Wistar rats were treated with 3,4-methylenedioxymethamphetamine (MDMA, ‘Ecstasy’) using either a high dose (4 × 5 mg/kg over 4 h) or low dose (1 × 5 mg/kg over 4 h) regimen on each of 2Expand
