After providing all the funding for The Brain from Top to Bottom for over 10 years, the CIHR Institute of Neurosciences, Mental Health and Addiction informed us that because of budget cuts, they were going to be forced to stop sponsoring us as of March 31st, 2013.

We have approached a number of organizations, all of which have recognized the value of our work. But we have not managed to find the funding we need. We must therefore ask our readers for donations so that we can continue updating and adding new content to The Brain from Top to Bottom web site and blog.

Please, rest assured that we are doing our utmost to continue our mission of providing the general public with the best possible information about the brain and neuroscience in the original spirit of the Internet: the desire to share information free of charge and with no adverstising.

Whether your support is moral, financial, or both, thank you from the bottom of our hearts!

Reasons Why We Curse

A few years back, the universality of swearing and curse words in all human languages attracted the attention of Harvard cognitive psychologist Steven Pinker. In his book The Stuff of Thought: Language as a Window into Human Nature, Pinker theorizes that the purpose of using swear words is to impose negative emotions on the people to whom we are talking, while stimulating primitive parts of their brain unbeknownst to them. Curse words appear to activate the brain’s right hemisphere more than the left, the basal ganglia (for generating them) and the amygdala (for perceiving them).

Of course, the words used to trigger negative emotions vary from culture to culture, but the most effective curses are associated with religion, excrement, or sexuality, or with ethnic minority groups. Pinker also believes that people use curses for not just one but many reasons: for example, to deliberately shock by avoiding euphemisms (he says that English has 34 euphemisms for the word “shit”), to intimidate or humiliate, to draw attention to something, or to express the informality of a situation.

We also curse when something unpleasant happens to us, and Pinker cites three possible explanations for this behaviour. Cursing may be a way of “blowing off steam”, or the human way of expressing the “rage circuit“ (like a wounded animal that roars to scare off its attacker), or, since swearing has a highly cultural content, simply a way of effectively signalling to the people around us the negative emotion that we are experiencing.

But in light of a recent study at Keele University, in the United Kingdom, we may have to add a fourth possible reason for swearing: to increase tolerance for pain. In this study, subjects were able to keep their hands submerged in ice-cold water longer if they cursed repeatedly at the same time. And the subjects who did not normally use foul language were much more likely to experience this painkilling effect!

The team that did this study believes that swearing triggers the “fight-or-flight” response, accelerating the heart rate, for example, and possibly promoting the secretion of endorphins, the body’s natural painkillers.
