While often looked over, communication noise can have a profound impact both on our perception of interactions with others and our analysis of our own communication proficiency. Forms of communication noise include psychological noise, physical noise, physiological and semantic noise. All these forms of noise subtly, yet greatly influence our ...
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 ...
"Ripples have been used to describe both abnormal activity associated with epileptiform sharp waves and normal behaviors such as physiological sharp waves and memory consolidation." [15] Synaptic noise is not only caused by mass signaling from surrounding neuronal impulses, but also from the direct signaling within the neuron itself.
Psychoacoustics is the branch of psychophysics involving the scientific study of the perception of sound by the human auditory system.It is the branch of science studying the psychological responses associated with sound including noise, speech, and music.
Extrinsic noise is characterised by expression levels of both genes covarying between cells, intrinsic by internal differences. Cellular noise is often investigated in the framework of intrinsic and extrinsic noise. Intrinsic noise refers to variation in identically regulated quantities within a single cell: for example, the intra-cell ...
Detection theory or signal detection theory is a means to measure the ability to differentiate between information-bearing patterns (called stimulus in living organisms, signal in machines) and random patterns that distract from the information (called noise, consisting of background stimuli and random activity of the detection machine and of the nervous system of the operator).
A well-known example of macroscopic neural oscillations is alpha activity. Neural oscillations in humans were observed by researchers as early as 1924 (by Hans Berger ). More than 50 years later, intrinsic oscillatory behavior was encountered in vertebrate neurons, but its functional role is still not fully understood. [ 3 ]
Psychophysiologically, beating and auditory roughness sensations can be linked to the inability of the auditory frequency-analysis mechanism to resolve inputs whose frequency difference is smaller than the critical bandwidth and to the resulting irregular "tickling" [3] of the mechanical system (basilar membrane) that resonates in response to ...
