Magnetoreception

by Robert B. Goldberg, Ph.D., Editor

Summary

A review article is summarized that discussed the difference between a magnetic directional (or compass) sense and a magnetic positional (or map) sense, the hypotheses that have been advanced to explain vertebrate magnetoreception, and the available evidence for each hypothetical mechanism. An examination was done of the cells involved in a magnetite-based magnetic sense in rainbow trout. The characteristics of the particular cells involved were discussed. A model for a mechanism for magnetoreception, namely magnetically sensitive chemical reactions whose rates are affected by the orientation of reactant molecules in a magnetic field is discussed in detail.
