exteroceptor

[¦ek·stə·rō¦sep·tər]
(physiology)
Any sense receptor at the surface of the body that transmits information about the external environment.

Exteroceptor

 

any one of a large group of specialized sensory structures that perceive stimulation arising from the external environment. Exteroceptors are situated on the surface of the bodies of animals and humans (including the mucous membranes of the nose, mouth, and tongue). Depending on the nature of the stimulus perceived, a distinction is made between mechanoreceptors of the skin (tactile), chemoreceptors (gustatory and olfactory organs), thermoreceptors of the skin, photoreceptors, and receptors of the organs of hearing and equilibrium. Dolphins, bats, and noctuids have receptors sensitive to ultrasound; some fishes are sensitive to electric fields.

Immediately after the completion of the exteroceptive behavioral experiment, the animals were sacrificed, and blood was collected for estimation of serum cholesterol by colorimetric method using a commercially available kit from Crest Biosystems.
It is the base of current data which are based on the interoperability and exteroceptive sensory information.
Therefore, a mobile robot must be able to localize or estimate its parameters also with respect to an internal world model by using the information obtained with its exteroceptive sensing system [7].
Exteroceptive sensors like Light incident detection and ranging (LIDAR) are used for environment scanning [7-8].
This interaction results in irreversible changes in neuronal function, adversely affecting the sensory fibres responsible for exteroceptive sensitivity and alters skeletal muscle function, resulting in paralysis and muscle atrophy in the hands and feet.
This idea seems to be plausible, since literature shows evidence of resurgence of key pecking (Doughty, da Silva & Lattal, 2007) and of temporal pattern of responses (Cancado & Lattal, 2011) that were trained in an experimental situation with exteroceptive stimuli.
