effect on V5 , is that we can finesse the inference that V5 shows motion-selective
responses with the assertion that these responses are mediated by afferents from V1 .
The two bilinear effects given in the preceding text represent two important
aspects of functional integration that DCM was designed to characterize.

17.7 CONCLUSION

Due to the concise nature of this review, we have been unable to cover a number of
related topics. These include computational neuroanatomy, analysis of group data
(whether structural or functional) using either fixed- or random-effect analysis. In
the context of the GLM, we omitted discussion of event-related vs. block designs,
parametric and factorial designs, and the factors underlying an efficient experimen-
tal design. We refer interested readers to the recent volume entitled “human brain
function” (32) that builds upon the basic issues introduced here. These methods and
all of the procedures covered in this review have been implemented in a public domain

software package called SPM2 available from http://www.fil.ion.ucl.ac.uk/spm/ .
