RATIONALE Marble burying and forced swimming behavior are widely used and sensitive tests for identifying clinically effective antidepressant drugs, although the underlying neurobiology of these behaviors is not fully elucidated. OBJECTIVES The objective of this study was to determine the relationship between the behavioral effects of antidepressant drugs(More)
INTRODUCTION The development of automated detection systems for animal behaviors is increasing in value in terms of saving time, objective analysis and reducing the need for well-trained experimenters. SCLABA(®) (Noveltec Inc., Kobe, Japan) is a commercially available analysis system originally developed for analyzing scratching behaviors in rodents, based(More)
Forming electrodes on opposite sides of an individual bismuth nanowire was attempted to prepare for Hall measurements. Although a 1-mm-long bismuth nanowire which is completely covered with a quartz template has been successfully fabricated to prevent oxidation, it is very difficult to attach Hall electrodes on the opposite sides of the nanowire due to the(More)
This paper develops a 24 GHz band FM-CW radar system to detect closed multiple targets in a small displacement environment, and its performance is analyzed by computer simulation. The FM-CW radar system uses a differential detection method for removing any signals from background objects and uses a tunable FIR filtering in signal processing for detecting(More)
INTRODUCTION In most publications on the forced swim test studies, duration of immobility is measured during the last 4 min of the 6-min testing period as a marker for depression. However, it is not clear if 4-min span best captures antidepressant-like drug effects. In the present study, six typical antidepressants in clinical use were evaluated over time.(More)
