Lecture six - Using Brain Body Interactions Flashcards
What is a neuroma?
What is TARGETED MUSCLE REINERVATION?
If someone had suffered spinal cord damage and was unable to move their limbs what are two ways through which they might be able to achieve limb movement?
Through the use a neural prothesis, which consists of a microelectrode array that sits on top of the cortex and picks up electrical impulses from the motor cortex and translates them into either 1) robotic limb movement or 2) movement of the individual’s own limb via a Neuromuscular Electrical Stimulator sleeve.
Why are sensory feedback prostheses important to develop?
What is the SOMATOSENSORY SYSTEM?
What are mechanoreceptors?
What are thermoreceptors?
What are nociceptors?
What are some of the different types of somatosensory receptors in the skin?
How does somatosensory information travel from the periphery to the brain?
Via the spinal cord.
Afferent nerves carrying somatosensory information connect with a spinal nerve via a specific vertebrae. The area of a skin a specific spinal cord innervates is called…?
A dermatome.
Does somatosensory information from above the spine, such as from the face, enter the spinal cord?
No. It goes straight into the brainstem.
Where is all somatosensory information sent when coming from the periphery?
To the thalamus and then on to the cerebral cortex, specifically the primary somatosensory cortex (within the parietal lobe).
What is the somatosensory ascending pathway of information from the periphery to the brain?
Does the primary somatosensory cortex have a somatotopic organisation?
Yes. This means that each area receives information from a certain part of the body, e.g. tongue, gums, thumb. This is the same for the primary motor cortex.
What is the role of the insular in processing sensory information?
It integrates the sensory information with emotion.
It is also responsible for our feeling of sense of self.
Also aids in putting emotional response to other people’s facial expressions.
