Book Description
Excerpt from Contributions to the Study of the Behaviour of Lower Organisms To explain the movements of organisms toward or from a source of stimulus, we find given almost universally in one shape or another a certain general formula. This is the schema set forth, with unessential variations, by Verworn (1899, pp. 500-502) for the orientation of a ciliate or flagellate infusorian to a one-sided stimulus, and by Loeb (1897, pp. 439-442) for the tropisms of organisms in general. Essentially, the schema is as follows: An agent acting upon the organism from one side causes the locomotor organs of that side to contract either more strongly or less strongly than those of the opposite side. In the former case (Fig. 1) the animal is turned away from the source of stimulus, till it comes into a position in which the motor organs of the two sides are similarly affected. Then progressing straight forward, it of course moves away from the source of stimulus (negative taxis or tropism).
