The insula is implicated in speech and language, taking part in functional and structural connections with motor neurons, linguistic, sensory, and limbic brain areas. [10] The knowledge about the function of the insula in speech production comes from different studies with patients having speech apraxia .
In the last two decades, significant advances occurred in our understanding of the neural processing of sounds in primates. Initially by recording of neural activity in the auditory cortices of monkeys [18] [19] and later elaborated via histological staining [20] [21] [22] and fMRI scanning studies, [23] 3 auditory fields were identified in the primary auditory cortex, and 9 associative ...
The temporal lobe is located beneath the lateral fissure on both cerebral hemispheres of the mammalian brain. [3] The temporal lobe is involved in processing sensory input into derived meanings for the appropriate retention of visual memory, language comprehension, and emotion association. [4]: 21 Temporal refers to the head's temples.
The notion of a dedicated language module in the human brain originated with Noam Chomsky's theory of Universal Grammar (UG). The debate on the issue of modularity in language is underpinned, in part, by different understandings of this concept. [4]
Speech mode hypothesis is the idea that the perception of speech requires the use of specialized mental processing. [53] [54] The speech mode hypothesis is a branch off of Fodor's modularity theory (see modularity of mind). It utilizes a vertical processing mechanism where limited stimuli are processed by special-purpose areas of the brain that ...
Subvocalization, or silent speech, is the internal speech typically made when reading; it provides the sound of the word as it is read. [1] [2] This is a natural process when reading, and it helps the mind to access meanings to comprehend and remember what is read, potentially reducing cognitive load.
The latest research looked at a part of the brain called the olfactory bulb, which processes information about smell. Humans have two olfactory bulbs, one above each nasal cavity. Humans have two ...
The human brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous ...
