such as how a particular organ works, what its function is and how it's affected by outside stimuli. For example, physiologists have studied how listening to music can causephysical changesin thehuman body, such as a slower or fasterheart rate, according to the journalPsychological Health Effe...
Although there is no universal agreement on the definition of life, scientists generally accept that the biological manifestation of life is characterized by organization, metabolism, growth, adaptation, response to stimuli and reproduction.[45] Life may also be said to be simply the characteristic st...
The mechanism of memory remains one of the great unsolved problems of biology. Grappling with the question more than a hundred years ago, the German zoologist Richard Semon formulated the concept of the engram, lasting connections in the brain that result from simultaneous “excitations”, whose pr...

Like placozoans, sponges lack a nervous system and muscle cells. They might not look like they move much, but they do contract and expand in response to stimuli, a behavior professor Sally Leys at the University of Alberta likens to a slow sneeze. ...
In the '60s,sexology pioneers William H. Masters and Virginia E. Johnson(remembered today as Masters and Johnson) broke barriers with their studies of orgasms and sexual stimuli, and some of their findings are still useful today. Hochberger, for example, cites Masters’ and Johnson’s “rule...
