The vast majority of animals are poikilotherms, and thus face the problem that the temperature of their nervous systems rather smoothly follows the temperature changes imposed by their environment. Since basic properties of nerve cells, e.g., the time constants of ion channels, strongly depend on temperature, a temperature shift likely affects the(More)
Insects exhibit an astonishing diversity in the design of their ears and the subsequent processing of information within their auditory pathways. The aim of this review is to summarize and compare the present concepts of auditory processing by relating behavioral performance to known neuronal mechanisms. We focus on three general aspects, that is frequency,(More)
Object recognition and classification by sensory pathways is rooted in spike trains provided by sensory neurons. Nervous systems had to evolve mechanisms to extract information about relevant object properties, and to separate these from spurious features. In this review, problems caused by spike train variability and counterstrategies are exemplified for(More)
We compare two optical tracking systems with regard to their suitability for soft tissue navigation with fiducial needles: The Polaris R system with passive markers (Northern Digital Inc. appropriate tool designs and assess the tool tip tracking accuracy under typical clinical light conditions in a sufficiently sized measurement volume. To assess the(More)
the maximum correlation value is chosen. The location giving maximum correlation value for the correct source estimates the exact scanning location. Two main issues in this extension of source camera identifi cation methods [3-5] are increase in computational complexity in estimating the correlation between reference pattern and test noise patterns of(More)

The Regional Monitoring Program for Water Quality in the San Francisco Estuary (RMP) is the primary source for long-term contaminant monitoring information for the Estuary. The RMP is an innovative and collaborative effort between the scientific community, the San Francisco Bay Regional Water Quality Control Board (Water Board), and the regulated discharger(More)
