(19) Thus, during the early stages of cerebellar ontogeny, when the migration pathway through the molecular layer is sparsely populated with cells and processes, the vertical process of a granule cell may seek actively a path of least resistance, utilizing 'contacts' with surrounding objects for avoidance, rather than as guideposts imperative for directing migration.
(20) The concepts of neutrality, anonymity, and abstinence, though of importance as guideposts in the conduct of an analysis, have conceptual limitations that not infrequently bind the analyst in a stance that is not useful for the progress of the analysis.
