The inhibitory role of the medial amygdala (MA) in maternal behavior control was explored. Injections of N-methyl-D,L-aspartic acid (NMA), an excitotoxic amino acid, into the MA resulted in a dramatic facilitation of maternal behavior in virgin female rats when pups were presented to them 12 days following the injections. This effect was specific to MA in(More)
UNLABELLED Traumatic brain injury (TBI) is a leading cause of disability in young people in the United States. Disorders of arousal and attention are common in closed head injury (CHI). Daytime drowsiness impairs participation in rehabilitation, whereas nighttime wakefulness leads to falls and behavioral disturbances. Sleep disturbances in TBI reported in(More)
Cardiovascular responses to increasing (20, 40, and 60%) concentrations of nitrous oxide or nitrogen in oxygen for 15 minutes as well as responses to 2 hours of exposure to 60% nitrous oxide or nitrogen in oxygen were determined and compared in 30 healthy, supine, untrained volunteers who received no other drugs or medications. No concentration of nitrogen(More)
Inhalation of 60% nitrous oxide in oxygen by seven adult male volunteers for 60 min was found to increase significantly polymorphonuclear leuocyte (PMN) chemotaxis, but not to influence total white or PMN blood cell counts. Also, the addition or morphine 0.2 mg kg-1 i.v. during the breathing of nitrous oxide did not alter any variable. These results(More)

Peripheral vascular and myocardial effects of increasing concentrations of nitrous oxide (0 to 70 per cent) in oxygen were determined in 15 unanaesthetized calves before and after replacement in their natural heart (NH) with a pneumatically driven artificial heart (AH). Nitrous oxide produced concentration-related decreases in arterial and mixed venous pH(More)
