What can spike train distances tell us about the neural code?

Time scale parametric spike train distances like the Victor and the van Rossum distancesare often applied to study the neural code based on neural stimuli discrimination.Different neural coding hypotheses, such as rate or coincidence coding,can be assessed by combining a time scale parametric spike train distance with aclassifier in order to obtain the optimal discrimination performance. The time scalefor which the responses to different stimuli are distinguished best is assumed to bethe discriminative precision of the neural code. The relevance of temporal codingis evaluated by comparing the optimal discrimination performance with the oneachieved when assuming a rate code.We here characterize the measures quantifying the discrimination performance,the discriminative precision, and the relevance of temporal coding. Furthermore,we evaluate the information these quantities provide about the neural code. Weshow that the discriminative precision is too unspecific to be interpreted in termsof the time scales relevant for encoding. Accordingly, the time scale parametricnature of the distances is mainly an advantage because it allows maximizing thediscrimination performance across a whole set of measures with different sensitivitiesdetermined by the time scale parameter, but not due to the possibility toexamine the temporal properties of the neural code.

Long-Range Goals for Iowa's Criminal& Junvenile Justice Systems, 2005

The attached plan builds upon work done over the last decade. The first plan developed after the creation of the Division of Criminal and Juvenile Justice Planning in 1986 was issued in 1990 and annually updated through 1994. Since 1992, the CJJPAC has been required to coordinate their planning activities with those of the Iowa Juvenile Justice Advisory Council (JJAC). In 1995, these two councils developed a new plan consisting of a set of long-range justice system goals to assist policy makers and justice system practitioners as they plan and operate the justice system through the next twenty years. The statutory mandate for such long-range planning required the identification of goals specific enough to provide guidance, but broad enough to be of relevance over a long period of time. The long-range goals adopted by these councils in 1995 covered a wide variety of topics and offered a framework within which current practices could be defined and assessed. Collectively, these long-range goals were meant to provide a single source of direction to the complex assortment of practitioners and policymakers whose individual concerns and decisions collectively define the nature and effectiveness of Iowa’s justice system. The twenty-year goals established in 1995 were reviewed by the councils in 2000 to assess their current relevance. It was determined that, with a few revisions, the goals established in 1995 should be restated in 2000 with a renewed emphasis on their long-range status. This plan builds upon those issued in 1995 and 2000, continuing much of the emphasis of plans, with some new directions charted as appropriate.
