In severe cases, it can affect movement of skin. In the United States, keloid scars are seen 15 times more frequently in people of sub-Saharan African descent than in people of European descent. [3] There is a higher tendency to develop a keloid among those with a family history of keloids and people between the ages of 10 and 30 years. [4]
In 1997 Elaine and Arthur Aron formally identified [4] sensory processing sensitivity (SPS) as the defining trait of highly sensitive persons (HSPs). [3] The popular terms hypersensitivity (not to be confused with the medical term hypersensitivity) or highly sensitive are popular synonyms for the scientific concept of SPS. [2]
[2] [3] Sensory processing disorder has been characterized as the source of significant problems in organizing sensation coming from the body and the environment and is manifested by difficulties in the performance in one or more of the main areas of life: productivity, leisure and play [4] or activities of daily living. [5]
Dr. Alexiades says that she believes keloids behave like benign tumors of the skin; the fibroblasts—the cells that make collagen—are proliferating and producing collagen out of control in keloids.
For example, when one tastes a potentially nutritious stimulus, the connectivity between the insula and a feeding network including the hypothalamus, ventral pallidum, and striatum is greater than when tasting a potentially harmful stimulus. These results support the existence of an integrated supramodal flavor system in the anterior ventral ...
The receptive field, or sensory space, is a delimited medium where some physiological stimuli can evoke a sensory neuronal response in specific organisms. [1]Complexity of the receptive field ranges from the unidimensional chemical structure of odorants to the multidimensional spacetime of human visual field, through the bidimensional skin surface, being a receptive field for touch perception.
For example, if somebody subjects their ears to extremely loud sounds, then they may experience hearing loss. This is probably a result of the tip links being broken. Normally the tip links grow back in about half a day, but for some people they are more fragile, making those individuals more susceptible to hearing loss.
Examples of medical conditions that can cause neuropathies are diabetes mellitus, chronic kidney disease, thyroid dysfunction (hyper- and hypothyroidism) as well as hepatitis, liver cirrhosis and alcohol dependency. Autism, sensory processing disorder, etc. can also affect haptic sensitivity. Loss of the sense of touch is a catastrophic deficit ...
