Hey there! I am a PhD student in neuroscience. At the moment I am working out the drifting gratings as visual stimuli to test the visual function of a rat disease model. To detect the response of the rat to this stimuli of Psychopy, I trained a neural network via DeepLabCut to get the details of the head movement, i.e. the direction, velocity. Nice to See you here, I am glad to change ideas with you
