Notes regarding the Units of Analysis

  • “Circuits” can refer to measurements of particular circuits as studied by neuroimaging techniques, and/or other measures validated by animal models or functional neuroimaging (e.g., emotion-modulated startle, event-related potentials).
  • “Physiology” refers to measures that are well-established indices of certain constructs, but that do necessarily not tap circuits directly (e.g., heart rate, event-related potentials).
  • “Behavior” can refer variously to behavioral tasks (e.g., a working memory task), or to behavioral observations.
  • “Self-reports” refer to interview scales, questionnaires, or other instruments that may encompass normal-range and/or abnormal aspects of the dimension of interest.
