Provas ciêntificas que o Amor é cego. Mas alguém tinha dúvidas?
Li um artigo interessantíssimo sobre o amor. O sumário é o que se segue e basicamente diz-nos com provas ciêntificas aquilo que há muito sabiamos: o amor é cego é sabe muito bem!
Romantic and maternal love are highly rewarding experiences. Both
are linked to the perpetuation of the species and therefore have a
closely linked biological function of crucial evolutionary importance.
Yet almost nothing is known about their neural correlates in the
human. We therefore used fMRI to measure brain activity in mothers
while they viewed pictures of their own and of acquainted children, and
of their best friend and of acquainted adults as additional controls. The
activity specific to maternal attachment was compared to that
associated to romantic love described in our earlier study and to the
distribution of attachment-mediating neurohormones established by
other studies. Both types of attachment activated regions specific to
each, as well as overlapping regions in the brain’s reward system that
coincide with areas rich in oxytocin and vasopressin receptors. Both
deactivated a common set of regions associated with negative emotions,
social judgment and ‘mentalizing’, that is, the assessment of other
people’s intentions and emotions. We conclude that human attachment
employs a push- pull mechanism that overcomes social distance by
deactivating networks used for critical social assessment and negative
emotions, while it bonds individuals through the involvement of the
reward circuitry, explaining the power of love to motivate and
exhilarate.
