Abstract:
Noise is generally considered to have deleterious effects on the sensitivity of a signal detection system. There are, however, several mechanisms whereby the addition of noise to the input of a system can in fact improve sensitivity. One such mechanism is stochastic resonance. Although first proposed in 1981, conclusive experimental evidence for "fully tuneable stochastic resonance" in biological systems has not previously been reported. Evidence of fully tuneable stochastic resonance in the response of afferents from Golgi tendon organs and the primary and secondary endings of muscle spindles to imposed muscle length changes is presented.

At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...
Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open.
Motor Unit Stimulation
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

Smooth Muscle Contraction
The onset of contraction is triggered by an increase in calcium ions within the sarcoplasm, similar to the process in striated muscle. However, smooth muscles have a relatively smaller reservoir of the sarcoplasmic...
Generation of Action Potential in Skeletal Muscles
Like neurons, muscle cells are also regarded as excitable due to their capacity to change in response to stimuli, primarily due to voltage-gated ion channels embedded in their plasma membranes, which get activated by alterations in the cell's...
