Neurophysiology is a branch of physiology and neuroscience concerned with the functions of the nervous system and their mechanisms. The term neurophysiology originates from the Greek word νεῦρον ("nerve") and physiology (which is, in turn, derived from the Greek φύσις, meaning "nature", and -λογία, meaning "knowledge"). [1]
The visual system and the somatosensory system are active even during resting state fMRI Activation and response in the sensory nervous system. The sensory nervous system is a part of the nervous system responsible for processing sensory information.
The somatosensory system comprises a diverse range of receptors and processing centers to produce the perception of touch, temperature, proprioception, and nociception. Receptors are located throughout the body including the skin, epithelia, internal organs, skeletal muscles, bones, and joints.
The following criteria are required to classify an event as an inattentional blindness episode: 1) the observer must fail to notice a visual object or event, 2) the object or event must be fully visible, 3) observers must be able to readily identify the object if they are consciously perceiving it, [3] and 4) the event must be unexpected and the failure to see the object or event must be due ...
A free nerve ending (FNE) or bare nerve ending, is an unspecialized, afferent nerve fiber sending its signal to a sensory neuron. Afferent in this case means bringing information from the body's periphery toward the brain.
The visual system is the physiological basis of visual perception (the ability to detect and process light).The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment.
Visual perception is the ability to interpret the surrounding environment using light in the visible spectrum reflected by the objects in the environment. The resulting perception is also known as visual perception, eyesight, sight, or vision (adjectival form: visual, optical, or ocular). The various physiological components involved in vision ...
