Rodgers R, Shepherd J, DONAT P
Neurosci Biobehav Rev . 1991 Jan; 15(4):489-95. PMID: 1792010
The effects of a number of 5-HT receptor ligands were examined on nonopioid defensive analgesia in male DBA/2 mice. MDL 73005EF (0.05-1.0 mg/kg), a selective 5-HT1A receptor agonist, potently and...

Blanchard D, Shepherd J, de Padua Carobrez A, Blanchard R
Neurosci Biobehav Rev . 1991 Jan; 15(4):461-8. PMID: 1686485
Female rats consistently show a pattern of differences in defensive behaviors compared to males which parallel the effects of exposure to a nonpainful threat stimulus (cat or cat odor) in...

Shepherd J, Hall-Craggs M, Finn J, Bingham R
Br J Radiol . 1990 Oct; 63(754):794-7. PMID: 2242477
Patient movement is the most common cause of image degradation when performing magnetic resonance scans in children. This is a particular problem scanning at high field, as noise levels of...

Rodgers R, Shepherd J
Eur J Pharmacol . 1990 Jul; 182(3):581-5. PMID: 2226625
The effects of MDL 72832, a potent and stereoselective ligand for 5-HT1A sites, on basal nociception and non-opioid defeat analgesia in male mice were examined. Neither (+)- nor (-)-MDL 72832...

Shepherd J, Rodgers R
Psychopharmacology (Berl) . 1990 Jan; 101(3):408-13. PMID: 2141947
The behavioural specificity of the hyperphagic effects of 8-OH-DPAT is a controversial issue. The present study addressed this question through the introduction of behavioural competition. Feeding behaviour in male mice...

Rodgers R, Shepherd J, Randall J
Neuropharmacology . 1990 Jan; 29(1):17-23. PMID: 2137563
Behavioural and pharmacological evidence indicates that non-opioid analgesia in defeated male mice is initiated by anxiety and that serotongergic (5-HT) substrates are implicated. In the present study, the effects of...

Hendrie C, Shepherd J, Rodgers R
Neuropharmacology . 1989 Oct; 28(10):1025-32. PMID: 2812281
The effects of the potent and selective CCK antagonist, MK-329, on morphine- and environmentally-induced analgesia were examined in male mice. The results show that MK-329 (0.005-0.1 mg/kg) was devoid of...

Shepherd J, Rodgers R
Behav Pharmacol . 1989 Jan; 1(1):75-83. PMID: 11175389
Behavioural and pharmacological evidence suggest that non-opioid analgesia in defeated male mice is a consequence of anxiety provoked by ecologically relevant aspects of the stimulus situation. The effects of acute...

Rodgers R, Shepherd J
Psychopharmacology (Berl) . 1989 Jan; 99(3):374-80. PMID: 2574479
Behavioural and pharmacological studies have suggested that anxiety may be an important factor in the initiation of non-opioid analgesia in defeated male mice. In the present study, the effects of...

Psychopharmacology (Berl) . 1989 Jan; 97(2):163-5. PMID: 2524855
Recent studies have suggested that anxiety may be an important factor in the non-opioid analgesic response to defeat in muroid rodents. In the present study, we have examined the influence...
