Somatosensory System Flashcards
How is sensory information transmitted in the brain? What are the similarities and differences of neural processing of different sensory modalities?
What kind of sensation does the sensory system support?
Touch, temperature, proprioception, organic senses, pruriception, nociception.
What are the four types of mechanoreceptors in the body’s surface?
Merkel’s disks, Ruffini endings, Meissner’s corpuscles, Pacinian corpuscles
What is a receptive field? How does the receptive field guide our sensory detection and discrimination?
How does the brain perceive somatosensory information? (What is the somatosensory neural pathway and how does this pathway inform us about the extent of sensory and motor impairments after a spinal cord injury?
What is a dermatome?
A surface area of the body innervated by a spinal segment.
How does sensory deprivation and experience affect sensory representation in the cortex?
Why do we have sensory illusion?
