What criteria would you use to determine whether synesthesia is a disorder or a variation of normal sensation and perception?
Why do you think that synesthesia is more common today than it was 20 years ago?
Why might it be possible for infants to have synesthesia, but the ability is gradually lost?
Would you want to take a genetic test for synesthesia? Cite a reason for your answer.
Do you think that synesthesia should be regarded as a learning disability, an advantage, or neither?
Cells questions for research and discussion:
Historical references as well as current anecdotal reports suggest that under very unusual circumstances, males can breastfeed. The Talmud, a book of Jewish law, discusses a man whose wife died and who had no money to pay a wet nurse (a woman who breastfeeds another woman’s child). He was able to nourish the child with his own body. The writings of other religions report similar tales. In agriculture, male goats can receive hormonal treatments and make milk. Do you think that it is possible for a human male to breastfeed, and if so, what conditions must be provided to coax his body to produce and secrete milk?
Select one of the mammals whose milk composition is listed in Table 1, read about the animal’s characteristics and activities on the Internet, and hypothesize why the proportion of the milk components is consistent with the animal’s behavior.
Compare the roles of mitosis and apoptosis in remodeling Sheila’s breast from a fatty sac to an active milk gland
