PSY398H5 Lecture Notes - Lecture 6: Pair Bond, Biological Specificity, Reward System
Document Summary
Additional pair bonding reading: pair bonding: one more component . Maintenance of a pair bond requires several components: Positive affective states associated with the presence of partner; negative affective states associated with absence. Balance between positive and negative affective states in the article they discuss positive affective state and the negative affective state, there is a balance between aversion and attraction the aversion is specifically is towards other conspecific. Whats interesting: you have animals who initially are attracted to other conspecifics until they find their mate. -> there is a switch the idea of flexibility and the plasticity of the brain. Opioid receptor subtypes: mu vs. kappa mu-opioid receptors = pair bond formation; partner separation. Presence and absence of partner signaled by beta-endorphin levels at mu-opioid receptor o lower activation of mu-opioid receptors will indicate separation kappa-opioid receptors = pair bond maintenance.
