You may be thinking of Stefania Follini. She was featured in one of the earlier Intro to Psych books I used - either Coons or Plotnik, I think. Lots of info about her on the internet. She was isolated in a cave for four months so circadian rhythms could be studied, as well as the effect of isolation. Interesting stuff.
