Sea Urchin Spermatozoa ChemotaxisModern version[1] of Lillie's historic 1902 sea urchin spermatozoa experiment.[2]
Chemotaxis is the attractive movement of an organism in response to a chemical stimulus, usually toward or "up" the chemical concentration gradient.
Kaubb's 2012 experiment[1] showing release of resact with a UV flash induces accumulation of sperm in the illuminated area while an annulus around the flash becomes depleted of sperm. After several seconds, the gradient dissipates because of resact binding and diffusion. (text from figure legend)
