The context is rather simple, scientific, and the time Sapolsky spent on it very short as it was just a brief mentioning.

Studies has shown that one particular part of the brain lights up on both situation involving arousal and situations involving threat. The theory suggested from this is that part of those committing sexual assault do so because their brain confuses signals of arousal with signal of threats.

As a side note to the above, he shortly mentioned that the researchers of the study wanted to create a official medical criteria/condition/wordIdon'tremember from this theory in order to raise funds for further research. However, politicians got involved and blocked it because of lobbying from feminist groups on the argument that doing this could lower jail sentences for convinced rapists.

The end result being that the feminist groups blocked this research on rape. It also match perfectly with the political rethric when it comes to rape, as I often see feminist group putting weight on the "fact" that those who commit sexual assault are completely healthy and "do not have a higher rate of Schizophrenia than anyone else", as if all mental conditions were linked to Schizophrenia.
