Social Behaviour Flashcards
How do vasopressin receptor expression differ in monogamous and non monogamous models
NMono - Higher expression in the Lateral Septum (LS) and Central Gray
Mono - Higher expression in Ventral Pallidum (VP) and Nucleus Accumbens (NAcc)
What are the effects of infusion of CSF and AVP (in CSF)
NMon - No effect of AVP on affiliative behaviours
Mon - AVP increases affiliative behaviour - time huddling partners
How do the expression of V1aR (AVP Receptor) in VP differ in Monogamous and promiscuous
NMon - low expression of V1aR in VP -> Vasopressin infusions do not prompt huddling
Mon - High expression of V1aR in VP -> Vasopressin infusion prompts huddling
T/F V1aR signalling in the VP is sufficient to induce monogamy in meadow vole males (naturally NonMono)
True
Can more oxytocin release strengthen relationships?
Yes
Where is expression of oxytocin Receptors (OTR) in Monogamous species
Higher expression in Nucleus Accumbens and prefrontal cortex (PFC) and Caudate/Putamen (CP)
T/F Oxytocin signalling in NAcc/PFC (but not the CP) is necessary for partner interaction
True
T/F Oxytocin Signalling in the acc (but not PLC) is more prominent in partner-directed grooming
True
What are characteristics of Autism Spectrum Disorder
Deficits in social and emotional exchange, in non verbal communications, repetitive movements, resistant to change in routine, unusually weak or strong responses to stimuli
connectivity issues in the brain -> Axons look like ladders
T/F Infants with ASD struggle with eye contact
False - Infants make a normal amount of eye contact at two months, eye contact declines over time
What is seen in mothers of children with autism
antibodies that attack certain brain proteins
What could halve the risk of autism in a child that a mother could consume during pregnancy
adequate amounts of folic acid
What does Risperidone do
sometimes reduces stereotyped behaviours of ASD (but has serious side effects)
