Popeye is a library for estimation of population receptive fields (pRF), accelerated with Cython and multiprocessing
A population receptive field (pRF) is a quantitative model of the cumulative response of the population of cells contained within a single fMRI voxel. The pRF model allows us to interpret and predict the responses of a voxel to different stimuli. Such models can be designed to describe various sensory and cognitive processes. More recently, the pRF model has also been used to map the retinotopic organization of multiple subcortical nuclei. Popeye allows users to fit pRFs for visual and auditory experiments and includes an API for cross-validation of the models.
