✦ Synopsis

With the Y-maze selection technique described in Part 1 2 strains of probably central nervous system (CNS) mutants have been isolated. These mutants show defects in the computation of both position and movement. One of these mutants (nofg B12) shows strong avoidance of small patterns moving with high velocity. This inversion of the object-induced orientation response can be mainly attributed to a "modification of responses to fast progressive (front-to-back) movement. It is thus possible that overall optomotor behaviour may be decomposed into a set of genetically independent modules.
