If someone gets hit hard in the head - why do they sometimes perceive light? A hit to the head sometimes creates an artifical AP in the cones of the eye, making it like they see light (according to some dudes quizlet.) abnormally trigger AP dude to law of specific nerve energies. transduce change environmental info into Action Potentials modality form of info (light, sound ect.) Know the six basic groups of receptors 1) Chemoreceptors: sense chemical stimuli 2) Photoreceptors: transduce light...
