Physiol Behav . 1993 Oct; 54(4):689-93. PMID: 7902586
In view of evidence suggesting that cholecystokinin (CCK) may have a role in the mediation of human panic disorders, it was predicted that CCK receptor antagonists may have anxiolytic-like activity...

Psychopharmacology (Berl) . 1993 Jan; 112(1):55-63. PMID: 7871010
Several behaviors associated with the serotonin syndrome have been reported in rats following administration of the 5-HT1A receptor agonist 8-OH-DPAT. The present investigation approached this phenomenon from an ethopharmacological perspective,...

Psychopharmacology (Berl) . 1993 Jan; 110(1-2):245-53. PMID: 7870893
The anxiety/defense test battery has been developed to assess defensive reactions in rats to situations associated with a natural predator, the domestic cat. This comprises three paradigms designed to study...

Rodgers R, Shepherd J
Psychopharmacology (Berl) . 1993 Jan; 113(2):237-42. PMID: 7855188
A single prior undrugged exposure to the elevated plus-maze has been reported to reduce open arm activity on retest and to attenuate/abolish the anxiolytic response to benzodiazepines at retest intervals...

Rodgers R, Shepherd J
Neuropharmacology . 1992 Jun; 31(6):553-60. PMID: 1407395
Recent studies have shown that non-opioid defensive analgesia in male mice is potently inhibited by the 5-HT3 receptor antagonist, ondansetron. The present series of experiments was conducted to further explore...

Shepherd J, Blanchard D, Weiss S, Rodgers R, Blanchard R
Pharmacol Biochem Behav . 1992 Mar; 41(3):551-8. PMID: 1584834
Mixed-sex groups of laboratory rats living in a visible burrow system (VBS) emit 18-27 kHz ultrasound and retreat to the burrow when a cat is placed in the open area...

Shepherd J, Flores T, Rodgers R, Blanchard R, Blanchard D
Physiol Behav . 1992 Feb; 51(2):277-85. PMID: 1557438
The anxiety/defense test battery has been developed to measure defensive reactions in laboratory rats to both direct exposure to, and stimuli associated with, a natural predator, the domestic cat. The...

Rodgers R, Lee C, Shepherd J
Psychopharmacology (Berl) . 1992 Jan; 106(1):102-10. PMID: 1738787
Recent studies have shown that brief exposure to an elevated plus-maze (EPM) produces non-opioid antinociception in male mice. The present experiments were designed to assess the effects of diazepam on...

Psychopharmacology (Berl) . 1992 Jan; 106(4):531-9. PMID: 1533722
The Proxemics/Activity test and the Eat/Drink test, two components of the Anxiety/Defense Test Battery, were developed to measure defensive reactions to situations associated with a natural predator (cat). In the...

Psychopharmacology (Berl) . 1992 Jan; 108(3):352-62. PMID: 1523285
The present study investigated the effects of the non-competitive NMDA antagonist MK-801 (0.04-0.16 mg/kg), on antipredator defensive reactions of male and female rats in three paradigms comprising the Anxiety/Defense Test...
