#the pupil is centered within the iris and those muscles are controlled through the autonomic nervous system

[pussy-ache]

it's naïve to think that love is pure magic, cuz in reality while some parts are magical it really is just dedication, patience, and empathy but the fact that our pupils dilate when we're in love is magical to me. like that's one of the magical things about it

#i think it's lovely #and the more you know about the eye the nicer it is #the pupil is centered within the iris and those muscles are controlled through the autonomic nervous system #love alters autonomic reactivity to emotions and automatically causes the pupils to dilate #the iris dilator muscle is controlled by the sympathetic nervous system #the link between pupil dilation and the sympathetic nervous system is why pupils dilate when in love and when aroused or both #there have been studies that compare a cocaine high to the same brain reactivity of falling in love #they've correlated ​MRIs of someone literally on cocaine vs someone who is asked to think about the person they're in love with #and who is shown pictures and videos of that person prior to the MRI itself #i think that's just lovely #i like that there's a physical component to it that can be studied and proven
