“…Renault and Lesevre (1978) reported the negative component of visual missing-stimulus potentials was larger in the right than in the left hemisphere. Hamada, Iwaki, and Kawano (2004) found a MEG signal with a peak latency of 160 to 180 ms after an infrequent sudden offset of continuous speech, whose equivalent current dipole was estimated in the right parietal cortex. In a functional imaging study, Miyauchi et al (1996) found a stronger activation in the right superior temporal sulcus when regularly presented tones were omitted infrequently than when not.…”

Cognitive processing associated with the recognition of computer malfunction was examined by recording event-related brain potentials time-locked to voluntary mouse button clicks that did not produce feedback from the computer. Sixteen university students performed a simple stimulus discrimination (oddball) task in auditory and visual modalities. Each button press produced either a target or a standard stimulus, or no stimulus response in some trials (missing stimulus, p=0.2). Biphasic missing-stimulus potentials appeared after the stimulus omission within a latency range of 150 to 550 ms. For both auditory and visual modalities, the initial negative component was dominant at the right temporal site, whereas the following positive component was at the central site. The peak latencies of these potentials were about 30 ms shorter in the auditory than in the visual modality, though the eliciting event was identical (i.e., stimulus omission). Brain potentials after users' operations may provide an objective and unobtrusive index of users' expectations in human-computer interaction.

“…A previous study of children with no hearing or auditory processing problems has shown negative correlations between FA and performance on a speech-in-noise task, with significant clusters seen in left and right prefrontal cortices, along with positive correlations between FA and task performance in the centrum semiovale bilaterally, reflecting connections with motor regions (Schmithorst et al, 2011). Activation of the right parietal cortex has previously been associated with processing global auditory changes (Hamada et al, 2004). Furthermore, several studies have found associations between auditory abilities and diffusion metrics, particularly in the corpus callosum (Farah et al, 2014; Owen et al, 2013).…”

This study assessed white matter microstructural integrity and behavioral correlates for children with severe congenital hypothyroidism (CH) who were identified and treated early following newborn screening. Eighteen children with severe CH and 21 healthy controls underwent a battery of behavioral measures of hearing, language and communication, along with diffusion MR imaging. Tract-based spatial statistics were performed on standard diffusion parameters of fractional anisotropy and diffusivity metrics. Microscopic diffusion anisotropy mapping based on the Spherical Mean Technique was also used to evaluate biologically specific metrics. Compared with age-matched controls, children with severe CH had poorer hearing and communication skills, albeit generally within normal limits. Children with severe CH had fractional anisotropy that was significantly lower in the cerebellum, bilateral thalami and right temporal lobe, and radial diffusivity that was significantly higher in the cerebellum and bilateral thalami. Microscopic fractional anisotropy and intra-neurite volume fraction were also significantly decreased, and transverse microscopic diffusivity was significantly increased, in the CH group in areas including the cerebellum, thalamus, occipital lobe, and corpus callosum, and in the white matter adjacent to sensorimotor cortex, particularly in the left hemisphere. Significant and widespread correlations were observed between behavioral measures and measures of white matter microstructural integrity in children with CH. The results indicate that children with severe CH who are identified through newborn screening may have significant brain white matter microstructural abnormalities despite early treatment.

“…The presence of cortical responses to sound offset was clearly demonstrated by the auditory-evoked potential (Takahashi et al 2004), neuromagnetic response (Gutschalk et al 2002;Hamada et al 2004;Hari et al 1987), and functional magnetic resonance imaging activation (Harms et al 2005;Okada et al 2004).…”

Comparison between offset and onset responses of primary auditory cortex ON-OFF neurons in awake cats. J Neurophysiol 97: [3421][3422][3423][3424][3425][3426][3427][3428][3429][3430][3431] 2007. First published March 23, 2007; doi:10.1152/jn.00184.2007. Primary auditory cortex (A1) neurons are believed not to carry much information about tonal offsets because A1 neurons in barbiturate-anesthetized animals are usually described as having only onset responses. We investigated tonal offset responses in comparison with onset responses in the caudal part of A1 of awake cats. Cells responding to both onsets and offsets were commonly found (59.2% of recorded cells). Offset responses usually co-occurred with phasic onset responses or phasic components of sustained responses. These ON-OFF cells had diverse combinations of offset-and onset-frequency-receptive field (FRF): offset-FRF was similar to onset-FRF, or narrower, wider, lower, or higher than onset-FRF. The distribution of FRF patterns was diffuse with no boundaries between the different FRF-pattern groups. The onset-versus offset-FRF pattern of each cell remained unchanged across multiple stimulus intensities. Mean offset response showed similar peak latency (19.5 vs. 21.5ms), longer half-decay time (74.5 vs. 48.5 ms), and lower peak amplitude (20.4 vs. 35.9 spikes/s) compared with the mean onset response. Although offset responses were facilitated when preceded by the suppression of spike activity, they were still elicited without preceding spike suppression. It is concluded that neurons showing paired onset and offset responses are predominant in the caudal A1. Their frequency-filtering property is usually not static but dynamic, changing between sound onsets and offsets. Offset responses are similarly precise and salient as onset responses for effectively encoding sound offsets. They may be elicited as active spike responses to sound offset rather than simple rebound facilitation.
