In order to determine the neural substrates of phonemic coding during both listening and speaking, we used a repetition suppression (RS) paradigm in which vowels were repeatedly perceived or produced while measuring BOLD activity with sparse sampling functional magnetic resonance imaging (fMRI). RS refers to the phenomenon that repeated stimuli or actions lead to decreased activity in specific neural populations associated with enhanced neural selectivity and information coding efficiency. Common suppressed BOLD responses during repeated vowel perception and production were observed in the inferior frontal gyri, the posterior part of the left middle temporal gyrus and superior temporal sulcus, the left intraprietal sulcus, as well as in the cingulate gyrus and presupplementary motor area. By providing evidence for common adaptive neural changes in premotor and associative auditory and somatosensory brain areas, the observed RS effects suggest that phonemic coding is partly driven by shared sensorimotor regions in the listening and speaking brain.

We aimed at identifying plurimodal large-scale networks for producing, listening to and reading word lists based on the combined analyses of task-induced activation and resting-state intrinsic connect...
The streams of sounds we typically attend to abound in acoustic regularities. Neural entrainment is seen as an important mechanism that the listening brain exploits to attune to these regularities and...
The phonemic merger phenomena is characterized by the inability of distinguishing two acoustically different phonemes, such as /n/ and /l/. Previous studies suggested that the process that drives the ...
Electroencephelogram (EEG) signals are non-stationary. This could be due to the internal fluctuation of brain states such as fatigue, frustration, etc. This necessitates the development of adaptive Br...

Tissue NECROSIS in any area of the brain, including the CEREBRAL HEMISPHERES, the CEREBELLUM, and the BRAIN STEM. Brain infarction is the result of a cascade of events initiated by inadequate blood flow through the brain that is followed by HYPOXIA and HYPOGLYCEMIA in brain tissue. Damage may be temporary, permanent, selective or pan-necrosis.
A type of mutation in which a number of NUCLEOTIDES deleted from or inserted into a protein coding sequence is not divisible by three, thereby causing an alteration in the READING FRAMES of the entire coding sequence downstream of the mutation. These mutations may be induced by certain types of MUTAGENS or may occur spontaneously.
Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous mat...
