Summary
-
1.
Hypotheses concerning the neural mechanisms by which the back swimmerNotonecta undulata locates prey have been examined using behavioral tests.
-
2.
The results are consistent with the following hypotheses: A. The receptor nearest the target controls the direction of the turn which is elicited by a stimulus (Figs. 2 and 3). B. Sensory input via a given receptor is capable of eliciting a very limited range of motor responses (Fig. 3). C. There are inhibitory interactions between receptors at some level of the central nervous system (Figs. 6 and 7C).
-
3.
A neuronal network analogous to a lateral inhibitory network is proposed to be the neural basis for the orientation (Fig. 5).
