Auditory Attention Activates Peripheral Visual Cortex
BACKGROUND Recent neuroimaging studies have revealed that putatively unimodal regions of visual cortex can be activated during auditory tasks in sighted as well as in blind subjects. However, the task determinants and functional significance of auditory occipital activations (AOAs) remains unclear. METHODOLOGY/PRINCIPAL FINDINGS We examined AOAs in an intermodal selective attention task to di...
متن کاملThe Sound of Silence
When choosing between alternatives of uncertain quality, one can learn from other decision-makers either through communicating with them about the reasons underlying their choices, or through simply observing their choices. The former way of learning has been extensively studied in the word-of-mouth (WOM) literature, while the latter way, labelled silent word-of-mouth (SWOM), has received less ...
متن کاملSound frequency representation in cat auditory cortex.
Using the intrinsic signal optical recording technique, we reconstructed the two-dimensional pattern of stimulus-evoked neuronal activities in the auditory cortex of anesthetized and paralyzed cats. The average magnitude of intrinsic signal in response to a pure tone stimulus increased steadily as the sound pressure level increased. A detailed analysis demonstrated that the evoked signals at ea...
متن کاملAuditory Neuroscience: Activating the Cortex without Sound
Sensory brain areas are usually characterized by their responses to external stimuli; however, neuroimaging studies have now shown that activation of auditory cortex occurs spontaneously and can be induced during silence by stimulus expectancy or mental imagery.
متن کاملUltrasound activates the auditory cortex of profoundly deaf subjects.
Using three-dimensional PET, the cortical areas activated by bone-conducted ultrasound were measured from five profoundly deaf subjects and compared with the cortical areas of normal-hearing subjects activated by stimuli through bone-conducted ultrasonic, air-conducted, bone-conducted, and vibro-tactile hearing aids. All of the hearing aids, including the ultrasonic hearing aid, consistently ac...
