Publishing fMRI results usually involves the presentation of slice images that show regions of increased BOLD (Blood Oxygen Dependent Signal). However, fMRI data is inherently three dimensional and often it is difficult to visualise or appropriately present data in 2D formats.
Therefore, it can be useful to implement a method for displaying graphics in 3D form. Luckily, there are some good javascript libraries that interact with the HTML5 canvas attribute to present 3D objects.
Psychophysics experiments often require passing messages and signals between different computers and devices. There are a number of methods that are generally used and the limitations of these methods are often a source of consternation for researchers.
Experiments designed to probe human temporal perception are particularly sensitive to timing errors in the apparatus. Therefore we have been developing a high resolution signal acquisition device for sending and receiving signals and doing some basic processing.
Recently, our lab has been working on a general timing measurement system to ensure that psychophysical timing of experiments is valid with different experimental setups ranging from calibrated lab CRT monitors to LCD projectors in MRI facilities.
Essentially, we aim to have a portable and easy to use recorder of digital and analogue signals that can be analysed for delays in hardware and software as well as jitter in various parameters.
