Following Karwoski, Odbert, and Osgood (1942, Journal of General Psychology 26 199-222), it is proposed that cross-sensory correspondences can arise from extensive, bi-directional cross-activation between dimensions of connotative meaning. If this account is correct, the same set of cross-sensory correspondences (eg brightness with high pitch, high pitch with sharpness, smallness ...

During sustained stimulation most sensory neurons will adapt their response by decreasing their sensitivity to the signal. The adaptation response helps shape attention and also protects cells from over-stimulation. Adaptation within the olfactory circuit of C. elegans was first described by Colbert and Bargmann(1,2). Here, the authors defined parameters of ...
