Parvocellular visual pathway
WebThis is the pathway composed of feature detectors (simple, complex and hypercomplex cells) as described in the basic information section. Parvocellular neurons show a low sensitivity to contrast, high spatial resolution, and low temporal resolution or sustained responses to visual stimuli. http://www.gregdetre.co.uk/notes/neuro_generals/parallel%20visual%20pathways.html
