Whether your perception of a wire is psychological is something else-- you could be experiencing a paresthesia from local afferent nerve injury or other neurological pathology.
22.
Optic nerve diseases such as optic neuritis or retrobulbar neuritis lead to dysfunction in the afferent nerve pathway once the signal has been correctly transmitted from retinal photoreceptors.
23.
Stretch-activated ion channels are located on these mechanoreceptor cells and serve to lower the action potential threshold, thus making the afferent nerves more sensitive to stimulation.
24.
Afferent and efferent are connected to affect and effect through their common Latin roots : Afferent nerves affect the subject, whereas efferent nerves allow the subject to effect change.
25.
Upon reorientation of the head relative to gravity, the cupula is weighted down by the dense particles, thereby inducing an immediate and sustained excitation of semicircular canal afferent nerves.
26.
The abstract says " Neural impulses in response to tactile stimulation of the shell were recorded from afferent nerve fibres in tortoises ( T . graeca and T . hermanni ).
27.
These convey an impulse to neurons in the medullary reticular formation which project down the reticulospinal tract and synapse with afferent nerve fibers in the spinal cord ( L1-L6 ).
28.
The afferent nerve fibers of the olfactory receptor neurons, transmit nerve impulses about odors to the central nervous system, where they are perceived by the sense of smell ( olfaction ).
29.
In sensory transduction, the afferent nerves transmit through a series of synapses in the central nervous system, first in the spinal cord or trigeminal nucleus, depending on the dermatomic area concerned.
30.
In other words, the afferent nerves are stimulated to evoke a reflex, which is typically expressed as a coordinated contraction of one or more muscles in response to the sensory nerve stimulation.
