Teitelbaum et al (1957)- lesions to LH in rats caused them to avoid eating + lose weight dramatically
Langhans 2001- when noraadrenaline/serotonin injected into LH/VMH- stop eating+ starvation occurs
Commentary-
reasonable to suggest that similar probs w hypothalamus cause AN food restriction, but sig generalisation from animale, in that humans would be able to understand that not eating would lead to death- they are not solely guided by appetite like rats.
Human evidence:
- Weller+Weller (1982)- humans suffering from hypothalamic tumours - suffered from AN
-supports idea that damage to hypo leads to AN sympotms, but doesnt prove that AN people dont feel hunger.
Also why mainly teenage girls (western, middle class) if hypothalamic dysfunction???
