RE: Attachment Theory: Anxious, Avoidant, Secure
07-08-2016 12:54 PM
Here is some info on OT (Oxytocin) as a pheromone that has nueromodulating effects on Attachment style and the stress response of the Amygdala in Humans.
here is some of the text about OT (oxytocin) and eye contact. It has lots more in the Oxytocin thread in Single Molecules started by kmacc45.

Quote:In humans, intranasal or intravenous application of OT was reported to improve a broad variety of complex social behaviours (for reviews see Heinrichs et al., 2009, MacDonald & MacDonald, 2010, Meyer-Lindenberg, 2008).
Specifically, intranasal OT increased trust in healthy men (Kosfeld et al., 2005) and even prevented betrayal-triggered decrease in trust (Baumgartner et al., 2008). In this context, OT increased ratings for trustworthiness and attractiveness of unfamiliar faces (Theodoridou et al., 2009). Moreover, OT"“treated subjects were significantly more generous than placebo-treated men during a generosity game (Zak et al., 2007). In general, OT seems to improve the interpretation of social cues (Domes et al., 2007b, Kosfeld et al., 2005), especially the recognition of fear (Fischer-Shofty el al., 2010).. OT also facilitates the recognition of faces (Rimmele et al., 2009) most effectively when they express positive emotion (Guastella et al., 2008b, Savaskan et al., 2008). In the context of ASD associated with avoidance of eye contact it is important to mention that OT promotes a gaze-shift towards the eye region of presented faces (Guastella et al., 2008a) also independent of their valence as this normally occurs during presentation of fearful faces (Gamer & Buchel, 2009). In the context of OT promoting social bondings it is of interest to mention initial studies demonstrating that OT enhanced attachment security (Buchheim et al., 2009)
Quote:On a more neurophysiological level, human functional imaging studies (fMRI) indicated that OT reduces amygdala responses to threatening, non-social scenes and to angry and fearful faces (Kirsch et al., 2005). More specifically, it could be shown that OT promotes the activity in amygdala regions involved in the processing of positive social stimuli (Gamer et al., 2010), an effect that was shown to generalize to facial expressions, irrespective of their valence (Domes et al., 2007a).

Oxytocin thought to works through amygdala, area of brain responsible for emotional memory
•Oxytocin injected into blood crosses blood brain barrier poorly (1/2 in blood ~5 min)
•Receptors for oxytocin found in nasal bulb in all mammals from rats to humans
•Oxytocin released in breath
•Inhaled oxytocin binds nasal receptors
