Hyposensitivity, also known as Sensory under-responsitivity, refers to abnormally decreased sensitivity to sensory input. Hyposensitivity is especially common for autistic people and is more often seen in children than adults and adolescents due to masking. Those experiencing this have a harder time stimulating their senses than normally.
Sensory modulation refers to a complex central nervous system process [1] [45] by which neural messages that convey information about the intensity, frequency, duration, complexity, and novelty of sensory stimuli are adjusted. [46] SMD consists of three subtypes: Sensory over-responsivity. Sensory under-responsivity; Sensory craving/seeking.
Disconnection anomia or modality-specific anomia: this subset of anomia affects patients' ability to name or distinguish objects if they are presented through a certain sensory modality, and is caused by a disconnect between the given sensory cortex and the language centers of the brain. For example, a patient may be able to distinguish an ...
Sensitization is a non-associative learning process in which repeated administration of a stimulus results in the progressive amplification of a response. [1] Sensitization often is characterized by an enhancement of response to a whole class of stimuli in addition to the one that is repeated.
The sensory nervous system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory neurons (including the sensory receptor cells), neural pathways , and parts of the brain involved in sensory perception and interoception .
Sensory overload occurs when one or more of the body's senses experiences over-stimulation from the environment. There are many environmental elements that affect an individual. Examples of these elements are urbanization , crowding , noise , mass media , and technology .
The DSM is unclear in whether writing refers only to the motor skills involved in writing, or if it also includes orthographic skills and spelling. [ 4 ] Dysgraphia should be distinguished from agraphia (sometimes called acquired dysgraphia) , which is an acquired loss of the ability to write resulting from brain injury , progressive illness ...
Multimodal perception is the ability of the mammalian nervous system to combine all of the different inputs of the sensory nervous system to result in an enhanced detection or identification of a particular stimulus. Combinations of all sensory modalities are done in cases where a single sensory modality results in an ambiguous and incomplete ...
