Question: Discuss similarities and differences of the anatomical pathways that convey touch sensation (not proprioception) and pain. Describe two functional consequences of these differences

Question: Our sense of touch reports many aspects of mechanical stimuli, including texture, motion, vibration etc. How is this discrimination, or ‘encoding' achieved at the level of sensory endings in the skin?

Question: Explain how ‘on-center' retinal ganglion cells increase their firing rates as illumination increases, while ‘off-center' retinal ganglion cells increase their firing rates when illumination decreases in the centers of their receptive fields

Question: All 4 sensory systems we discussed have orderly representations of their stimuli in primary sensory cortex (eg. somatotopy in SI somatosensory cortex). Briefly describe that organization for all four systems (somatic sensation, pain, vision, auditory system). One sentence should be sufficient for each system.
