There are probably few people who have not seen some version of this cartoon showing the differences between male and female brains. The funny part is that this might be true. Take the following report from the journal NeuroReport: Nucleus accumbens activation mediates the influence of reward cues on financial risk taking. NeuroReport March 26, 2008 19(5):509-513.
The money quote
"...we predicted and found that anticipation of viewing rewarding stimuli (erotic pictures for 15 heterosexual men) increased financial risk taking..."In other words, erotic pictures caused these men to take bigger monetary gambles than pictures of neutral (household appliances) or scary objects (snakes and spiders). Interesting next time I am going to the stock market, I will make sure to have playboy with me.
