Study at U.C. Berkeley Reaffirms Efficacy of Human Pheromone
Sciences, Inc.’s Patented Technology

The study, performed by members of the Helen Wills Neuroscience Institute and the Department of Psychology at the University, measured in 60 subjects the effects of just sniffing various concentrations of the compound on autonomic nervous system function and mood. Simply stated, higher concentrations of this compound increased positive mood and decreased negative mood in the women tested. Psychological and physiological evaluation methods were used to measure the effects on the women in the study.

Study Finds Brain Reacts To Sex-Specific Chemicals
Washington Post
Certain chemicals similar to the male and female sex hormones trigger distinctive brain activity when sniffed by the opposite gender, providing the strongest evidence yet for the existence of human “pheromones,” scientists reported yesterday.

Brain scans of two dozen volunteers in Sweden found that a part of the brain involved in regulating sexual behavior lit up when women were exposed to a substance similar to testosterone, while the same brain area in men lit up when they were exposed to a substance similar to estrogen.

Brain activity is influenced by chemical signals undetectable as odors, University of Chicago researchers find
University of Chicago News
Researchers at the University of Chicago have found for the first time that airborne “chemosignals,” substances undetectable as odors, have a measurable impact on brain metabolism, according to a report released Wednesday, July 25.

A team of scientists led by the University’s Martha McClintock, one of the nation’s leading experts on chemosignals and pheromones, and Suma Jacob, a University researcher, found marked differences in the brain activity among women exposed to the naturally produced male steroid androstadienone when compared to themselves when they had not been exposed to the substance.

A Sixth Sense that Affects How You Feel
Fortune Magazine
An imaginative University of Utah anatomist named David L. Berliner
was working with substances that occur in human skin. When he left some of the ex tracts in open vials around the lab, he noticed a sudden, puzzling rise in camaraderie among a previously acrimonious group of researchers working with him. When he changed the extracts a few months later, the group resumed its contentious ways.

Berliner froze and saved the extracts. Nearly 30 years later, by this time a Silicon
Valley biotech  millionaire, thanks to a method of containing drugs and cosmetics
inside tiny, sponge-like polymer spheres, he returned to the subject. In 1989 he established the company, which has isolated the suspected good-fellowship pheromones-behavior-controlling substances similar to those already known to stimulate sexual activity in animals.

For Gay Men, an Attraction to a Different Kind of Scent
New York Times
Using a brain imaging technique, Swedish researchers have shown that homosexual and heterosexual men respond differently to two odors that may be involved in sexual arousal, and that the gay men respond in the same way as women.

The new research may open the way to studying human pheromones, as well as the biological basis of sexual preference. Pheromones, chemicals emitted by one individual to evoke some behavior in another of the same species, are known to govern sexual activity in animals, but experts differ as to what role, if any, they play in making humans sexually attractive to one another.

A Gene for Romance, So it Seems
New York Times
Biologists have been making considerable progress in identifying members of a special class of genes, those that shape an animal’s behavior toward others of its species. These social behavior genes promise to yield deep insights into how brains are constructed for certain complex tasks.

Social behavior genes present a particular puzzle since they involve neural circuits in the brain, often set off by some environmental cue to which the animal responds. Catherine Dulac of Harvard has found that the male mouse depends on pheromones, or air-borne hormones, to decide how to behave toward other mice. It detects the pheromones with the vomeronasal organ, an extra scent-detecting tissue in the nose.

In Lobster Courtship, Traits Like Humans
New York Times
People who study animal behavior try not to describe their research subjects in human terms, but that is hard to avoid when it comes to lobsters.

The newly molted female will stay in the male’s shelter for a few days or more, until her new shell hardens. By then, it seems, the thrill is over. She has what she wants, a plug of sperm in a tiny pouch that Mr. Corson likens to a fanny pack. And so she’s gone.
