Bayesian Tuning Curve Analysis

Description: Java libraries and Matlab wrappers for fully Bayesian estimation of parametric tuning curves with various noise models. This package is built on the Blaise toolkit, and contains examples for model comparison and hypothesis testing.

WiiFit Balance Board Recording

Update Aug 2014: This code is not actively maintained — check-out the CU Wii Balance Board Project
Description: This is an extension of a Matlab library originally by Aaron Striegel’s group at Notre Dame that allows you to record from a WiiFit Balance Board. This version works with Matlab 2007a, but I haven’t tested it on any other versions. The code contains an updated (v1.6) version of the, very cool, WiiLib library.
