Neuronal activity at the microscopic level has a stochastic character, with atomic collisions and agitation, that may be termed "noise." [4] While it isn't clear on what theoretical basis neuronal responses involved in perceptual processes can be segregated into a "neuronal noise" versus a "signal" component, and how such a proposed dichotomy could be corroborated empirically, a number of ...
If the person does not fall into a fully flat, supine position, and the head remains elevated above the trunk, a state similar to a seizure may result from the blood's inability to return quickly to the brain, and the neurons in the body will fire off and generally cause muscles to twitch very slightly but mostly remain very tense. [citation ...
However, the stapedial muscle is innervated by the facial nerve while the tensor tympani is innervated by the trigeminal nerve. The tensor tympani pulls the manubrium of the malleus inwards and tightens it while the stapedial muscle pulls the stapes inward. This tightening damps the sound vibration that is allowed to penetrate the cochlea.
Similar findings were shown in parallel by the group of Eckhorn, providing further evidence for the functional role of neural synchronization in feature binding. [82] Since then, numerous studies have replicated these findings and extended them to different modalities such as EEG, providing extensive evidence of the functional role of gamma ...
A reflex from hearing a sudden loud noise will happen in the primary acoustic startle reflex pathway consisting of three main central synapses, or signals that travel through the brain. First, there is a synapse from the auditory nerve fibers in the ear to the cochlear root neurons (CRN).
A nerve is an enclosed, cable-like bundle of nerve fibers (called axons) in the peripheral nervous system. Nerves have historically been considered the basic units of the peripheral nervous system. Nerves have historically been considered the basic units of the peripheral nervous system.

Various nerve stimulation patterns may be used in neuromuscular function monitoring and the response to these stimulation patterns is used to assess the depth of neuromuscular blockade. Some patterns of stimulation used today include, single twitch (ST), train-of four (TOF), [11] double burst stimulation (DBS), tetanic stimulation
