A mating dance may be used as an example. Many species of birds engage in a specific<br />

series of elaborate movements, usually by a brightly colored male. How well they perform<br />

the "dance" is then used by females of the species to judge their fitness as a potential mate.<br />

<strong>The</strong> key stimulus is typically the presence of the female.<br />

Although fixed action patterns are most common in animals with simpler cognitive<br />

capabilities, humans also demonstrate fixed action patterns. For example, infants grasp<br />

strongly with their h<strong>and</strong>s as a response to tactile stimulus."<br />

"A taxis (plural taxes) is an innate behavioural response by an organism to a stimulus. A<br />

taxis differs from a tropism (turning response, often growth towards or away from a stimulus)<br />

in that the organism has motility <strong>and</strong> demonstrates guided movement towards or away from<br />

the stimulus. It also differs from a kinesis, a non-directional change in activity in response to<br />

a stimulus that results in the illusion of directed motion due to different rates of activity<br />

depending on stimulus intensity.<br />

For example, flagellate protozoans of the genus Euglena move towards a light source. Here<br />

the directional stimulus is light, <strong>and</strong> the orientation movement is towards the light. This<br />

reaction or behaviour is a positive one to light <strong>and</strong> specifically termed "positive phototaxis",<br />

since phototaxis is a response to a light stimulus, <strong>and</strong> the organism is moving towards the<br />

stimulus. If the organism moves away from the stimulus, then the taxis is negative. Many<br />

types of taxis have been identified <strong>and</strong> named using prefices to specify the stimulus that<br />

elicits the response. <strong>The</strong>se include anemotaxis (stimulation by wind), barotaxis (pressure),<br />

chemotaxis (chemicals), galvanotaxis (electrical current), geotaxis (gravity), hydrotaxis<br />

(moisture), phototaxis (light), rheotaxis (fluid flow), thermotaxis (temperature changes)<br />

<strong>and</strong> thigmotaxis (physical contact).<br />

Chemotaxis is a migratory response elicited by chemicals. Unicellular (e.g. protozoa) or<br />

multicellular (e.g. worms) organisms are targets of the substances. A concentration gradient<br />

of chemicals developed in a fluid phase guides the vectorial movement of responder cells or<br />

organisms.<br />

Electrotaxis is directional movement of motile cells in response to a electric field. It<br />

has been suggested that by detecting <strong>and</strong> orientating themselves toward the electric fields.<br />

This notion is based on 1) the existence of measurable electric fields that naturally occur<br />

during wound healing, development <strong>and</strong> regeneration; <strong>and</strong> 2) cells in cultures respond to<br />

applied electric fields by directional cell."<br />

"... reproductive chemical-electrical impulses stimulated by testosterone or<br />

estrogen."<br />

"Testosterone is a steroid hormone from the <strong>and</strong>rogen group. In mammals, testosterone is<br />

primarily secreted in the testes of males <strong>and</strong> the ovaries of females, although small amounts<br />

are also secreted by the adrenal gl<strong>and</strong>s. It is the principal male sex hormone <strong>and</strong> an<br />

anabolic steroid.<br />
