Skin conductance was measured in 10 subjects with a DC Wheatstone bridge in 10 areas purportedly containing acupuncture loci on the Triple Burner (TB) and Lung (Lu) meridians. When the results were compared to those from anatomically similar locations devoid of acupuncture loci, local conductance variation was found to be significantly different (p less(More)
The natural variation in maternal care is an interesting model to analyze the physiological mechanisms that lead to differences in the mother-infant interaction. Several studies have shown differences in the expression of brain receptors such as the dopamine, estrogen and oxytocin receptors in areas classically involved in the onset and/or maintenance of(More)
The AC impedance of a length of the H meridian not containing any acupuncture points was studied by means of Laplace plane analysis of the time domain response to an input voltage pulse. The ensuing frequency domain data were compared to the results of an identical analysis for two anatomically similar controls on either side of the meridian. The resistance(More)
The frequency dependence of the skin impedance between two acupuncture points (H-3 and H-4) was determined by Laplace plane analysis of the time domain response to an input voltage perturbation. Both the resistance and capacitance between the acupuncture points differed significantly from the corresponding controls, thus supporting the interpretation of the(More)
For most mammalian species, maternal behavior has an essential role in the development of the offspring. The frequency of licking/grooming (LG) the pups has been used as a parameter to evaluate maternal care, having mothers with high (HL) or low (LL) frequencies of LG. This study aimed to analyze the gene expression of the receptors for dopamine (Drd1a),(More)
Central oxytocin (OT) and arginine-vasopressin (AVP) have been shown to play an important role in sexual behavior and neuroendocrine secretion in rodents. The results of exogenous OT administration on sexual behaviors in male and female mice are controversial. This study aimed to analyze the role of OT in sexual behavior, the number of oocytes and the(More)
Social relations are built and maintained from the interaction among individuals. The oxytocin (OT), vasopressin (VP), estrogen, dopamine, and their receptors are involved in the modulation of sexual behavior in females. This study aimed to analyze the impact of OT gene knockout (OTKO) on sexual behavior and the gene expression of oxytocin (OTR), estrogen(More)
