Abstract

The program TRACK-ANALYZER runs on AT-compatible microcomputers and performs off-line analysis of data recorded from Morris water-maze experiments by means of a video tracking system or digitizing tablet. Raw data must be available on disk as ASCII-files listing position coordinates sampled at a constant frequency. Automatic recognition and correction of artifacts and missing data is a key feature of the program, as well as the option to combine commands to user-defined macros. TRACK-ANALYZER offers maximal flexibility regarding experimental schedule, maze geometry and recording parameters and may also be used to analyze open-field activity. In addition to calculating basic parameters of the swim path, such as path length and time, the program counts crossings and hits of goal platform and four virtual reference annuli, calculates search times in five different maze fields, determines directionality, tortuosity and turning preferences of swimming behavior and allows the viewing of any number of trials simultaneously on screen. ASCII-formated data output may easily be exported to commercial statistics and graphics software.

      For the time-course analysis, the total observation time was portioned into 6 periods of 10 min. The standard hidden-platform version of the water maze was done as previously described [24,25]. Briefly, the test included an acquisition phase (18 trials, 6/day, inter-trial time 30–40 min) followed by a reversal phase during which the platform was moved to the opposite position (12 trials, 6/day).

      Also, the ability to bind observations across multiple spatial learning tasks (which produce heterogeneous data in terms of performance indicators, protocols, maze shapes, and task complexity) is a necessary condition toward a unified view of the mechanisms underpinning spatial cognition. During the last decades, these considerations have given rise to a substantial effort to conceive automated analysis tools and data management systems (e.g. Bradley et al., 2005; Drai and Golani, 2001; Wolfer and Lipp, 1992; see Section 4 for a Discussion on existing solutions). This paper presents a Navigation Analysis Tool (NAT) that was explicitly designed to cope with large behavioral datasets, and to draw coherent interpretations across multiple spatial learning tasks (e.g. involving both open-field and structured mazes).

      It is notable that the effects of manipulating TrkB receptors were most obvious during the acquisition of spatial navigation, which involves not only hippocampal-dependent spatial memory but also adaptation of an effective coping strategy (thigmotaxis), which is more closely related to frontal cortical functions. In contrast, TrkB receptor manipulation did not affect search bias which is considered the most selective measure for hippocampal-dependent spatial memory (Wolfer and Lipp, 1992). It is also worth noting that in APdE9 mice the memory enhancing effect of TrkB.TK was more robust than the memory impairing effect of TrkB.T1.

      For exploration tests and water maze test, animals were video-tracked using the EthoVision 2.3 system (Noldus Information Technology, Wageningen, The Netherlands) using an image frequency of 4.2/second. Raw data were transferred to Wintrack 2.4 (http://www.dpwolfer.ch/wintrack)22 for off-line analysis. Statistical computations were done using Statview 5.0 (SAS Institute, Cary, NC).
