Regardless Of Genotype, Offspring Of Vip-Deficient Female Mice Exhibit Developmental Delays And Deficits In Social Behavior., Hewlet Mcfarlane
Regardless Of Genotype, Offspring Of Vip-Deficient Female Mice Exhibit Developmental Delays And Deficits In Social Behavior., Hewlet Mcfarlane

Pharmacological studies indicate that vasoactive intestinal peptide (VIP) may be necessary for normal embryonic development in the mouse. For example, VIP antagonist treatment before embryonic day 11 resulted in developmental delays, growth restriction, modified adult brain chemistry and reduced social behavior. Here, developmental milestones, growth, and social behaviors of neonates of VIP-deficient mothers (VIP +/-) mated to VIP +/- males were compared with the offspring of wild type mothers (VIP +/+) mated to VIP +/+ and +/- males, to assess the contributions of both maternal and offspring VIP genotype. Regardless of their own genotype, all offsprings of VIP-deficient mothers exhibited …

Reduced Ultrasonic Vocalizations In Vasopressin 1b Knockout Mice., Hewlet Mcfarlane

The neuropeptides oxytocin and vasopressin have been implicated in rodent social and affiliative behaviors, including social bonding, parental care, social recognition, social memory, vocalizations, territoriality, and aggression, as well as components of human social behaviors and the etiology of autism. Previous investigations of mice with various manipulations of the oxytocin and vasopressin systems reported unusual levels of ultrasonic vocalizations in social settings. We employed a vasopressin 1b receptor (Avpr1b) knockout mouse to evaluate the role of the vasopressin 1b receptor subtype in the emission of ultrasonic vocalizations in adult and infant mice. Avpr1b null mutant female mice emitted fewer ultrasonic …
Social Habituation And Dishabituation In Cd-1 Mice Treated With The Norepinephrine Neurotoxin N-(2-Chloroethyl)-N-Ethyl-2-Bromobenzylamine (Dsp-4), Hewlet Mcfarlane
Social Habituation And Dishabituation In Cd-1 Mice Treated With The Norepinephrine Neurotoxin N-(2-Chloroethyl)-N-Ethyl-2-Bromobenzylamine (Dsp-4), Hewlet Mcfarlane

Male CD-1 mice between postnatal days 60 and 90 were injected intraperitoneally (i.p) with either water vehicle (controls) or 50$\mu$g/g of the norepinephrine neurotoxin N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP-4). They were tested 3 to 6 days later on the odors of adult males in a four-trial habituation/dishabituation paradigm. There were four groups: group CSS were water injected and exposed to the same male on all four trials; group CSN were water injected and exposed to the same male on the first three trials and a novel one on the fourth; group DSN were DSP-4 treated and exposed the same male on the first …
