Analysis techniques for Dry Mazes, Morris Water Maze and the Open Field Test

Characterization and Quantification of Spatial Learning Strategies.

These really fall into the category of sharing ones own notebook with the online community and I'm afraid without scaffolding - but I still welcome informed feedback. We've been looking at an additional "derivative" class of analysis parameters that might be shared over multiple assays. These include turning latency, decision frequency and decisional entropy.  There is a considerable similarity between some of my previous predictive behavior work and OFT/MWM etc in that the concept of choice modeling as a temporal Markov chain occurs in both.  Looking at the way things are modelled, measuring the first differential of the data refocuses the assay in the subjects decision making process and search strategies and moves the analysis to an animal centred approach from what is otherwise a meta analytical approach.

Open Field Test Analysis

Here are the new screenshots of the HVS Image Open Field Test Analysis module in HVS Image 2013. Its set to a 5x5 grid but actually grid sizes can be anything from 2x2 to 255x255. As always you can define HVS Custom files but now you you choose the special areas in the Open Field Test Analysis by pointing and clicking on them. Multiple files are selected by clicking and multi-selecting the source data files.
