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.
Different forms of micrographia. Micrographia is an acquired disorder characterized by abnormally small, cramped handwriting. [1] It is commonly associated with neurodegenerative disorders of the basal ganglia, such as in Parkinson's disease, but it has also been ascribed to subcortical focal lesions. [2]
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 ...
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 ...
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 .
It is important that the information of these different sensory modalities must be relatable. The sensory inputs themselves are in different electrical signals, and in different contexts. [6] Through sensory processing, the brain can relate all sensory inputs into a coherent percept, upon which our interaction with the environment is ultimately ...
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 .
