Noise physiological

Senses includes any personal physiological reactions to incident proximity, such eis smell, odd noise, dizziness, etc. 

I believe, absolutely, that chemicals can alter our physiology, which can result in addictive behaviors, fear, even violence. There are chemicals that attack our nervous systems and affect our hormones, which changes our emotions and our ability to tolerate stress. So we can t take noise anymore, and we can t take the kids yelling, or three things happening at the same time. We blame our kids or the noise instead of blaming that which undermines our nervous system. We... 

Sources of Physiological Noise. Despite the apparent importance of Hb, in the literature, the change in HbO is most widely reported and sometimes is the sole response reported. HbO is sometimes preferred due to its higher sensitivity to NIR based measurements than Hb. However, HbO measurements are not without disadvantages. There have been some studies (see for example [77] [22] [23] [47]) which indicate the presence of low frequency modulation ( 0.1 Hz) of both vascular (Hb, HbO) and metabolic (cytocrhome-c-oxidase) responses to visual stimuli with unknown origin. The cause of these low frequency oscillations are... 

Removing Physiological Noise. One method of removing the low frequency artifact is to convolve the response signal with a model of stimulus signal. Such methods have been used to increase the SNR in fMRI [54], The stimulus signal is usually modeled as a pulse train with evenly spaced interstimulus interval as in Equation (11)... 

Noise can strongly arouse the sympathetic division and hence can be physiologically wearing. As such, it is a significant detractor from health and happiness. 

In a fear-conditioning experiment, a neutral stimulus, such as a tone or a light, is paired with an aversive stimulus, such as a shock, a loud noise, or an aversive air blast. Following this experience, the formerly neutral stimulus becomes a conditioned stimulus (CS-F) and acquires the ability to elicit behaviors and physiological responses formerly only associated with the aversive stimulus, the unconditioned stimulus (UCS). Enthusiasm for this work derives at least partly from the precise delineation of neural circuits, down to the level of the genome, engaged by environmental components that produce fear conditioning (LeDoux,... 

The barrier to isomerization of rhodopsin in the dark is physiologically important because it limits the noise in our perception of light. If the barrier were low enough to be overcome thermally, discrimination of light from dark would be more difficult. 

Under some conditions, feelings of sleepiness may be great and protocols that must be run when subjects are extremely sleepy encounter the problem of floor effects. For example, physiological sleepiness may be so great because of a drag effect that sleep latencies are too short to be above statistical noise. In these circumstances, it is difficult to detect subjects with abnormal sleepiness or to detect the effect of any remedial intervention.
