Sensory impairments caused by neurological or physical disorders hamper kinesthesia, making rehabilitation difficult. In order to overcome this problem, we proposed and developed a novel biofeedback prosthesis called Auditory Foot for transforming sensory modalities, in which the sensor prosthesis transforms plantar sensations to auditory feedback signals. This study investigated the short-term...

Introduction: The basolateral amygdala (BLA) and infralimbic area (IL) of the medial prefrontal cortex (mPFC) are two interconnected brain structures that mediate both fear memory expression and extinction. Besides the well-known role of the BLA in the acquisition and expression of fear memory, projections from IL to BLA inhibit fear expression and have a critical role in fear extinction. Howev...

cavernous hemangioma is a rare benign tumor of the internal auditory canal (iac) of which fourteen cases have been reported so far. tinnitus and progressive sensorineural hearing loss (snhl) are the chief complaints of the patients. audiological and radiological planes, ctscan, and magnetic resonance image (mri) studies are helpful in diagnosis. the only choice of treatment is surgery with elec...

Closing the eyes helps memory. We investigated the mechanisms underlying the eyeclosure effect by exposing 80 eyewitnesses to different types of distraction during the witness interview: blank screen (control), eyes closed, visual distraction, and auditory distraction. We examined the cognitive load hypothesis by comparing any type of distraction (visual or auditory) with minimal distraction (b...

Sensory systems influence one another during development and deprivation can lead to cross-modal plasticity. As auditory function begins before vision, we investigate the effect of manipulating visual experience during auditory cortex critical periods (CPs) by assessing the influence of early, normal and delayed eyelid opening on hearing loss-induced changes to membrane and inhibitory synaptic ...

This study investigated the effect of visual and auditory degradation on the weighting given by listeners to visual cues for tokens produced by native and non-native speakers. ‘Ba’, ‘da’ and ‘ga’ syllables uttered by English and Chinese speakers were presented in auditory (A), visual (V) and congruent/incongruent audiovisual (AV) conditions to English listeners. In some conditions, the visual c...

We studied the modification of auditory perception in three different conditions in twenty subjects. Observing other person's discordant articulatory gestures deteriorated identification of acoustic speech stimuli and modified the auditory percept, causing a strong McGurk effect. A similar effect was found when the subjects watched their own silent articulation in a mirror and acoustic stimuli ...

The presentation of visual stimuli of moving mouth is known to affect the phoneme perception of the auditory stimuli during natural speech, and provides important insights into the scientific and technological study of speech. In order to investigate the laterality of the audio-visual integration we studied the relationship between the McGurk effect (McGurk and McDonaold 1976) and Right Ear Adv...

When two objects are flashed at one location in close temporal proximity in the visual periphery, an intriguing illusion occurs whereby a single flash presented concurrently at another location appears to flash twice (the visual double-flash illusion: Chatterjee et al., 2011, Wilson & Singer, 1981). Here, for the first time, we investigate the time course of the effect, and directly compare it ...

The influence of top-down cognitive control on 2 putatively distinct forms of distraction was investigated. Attentional capture by a task-irrelevant auditory deviation (e.g., a female-spoken token following a sequence of male-spoken tokens)-as indexed by its disruption of a visually presented recall task-was abolished when focal-task engagement was promoted either by increasing the difficulty o...
