“…One possibility is that the repurposing of the auditory cortex does extend to primary auditory regions, but the relevant functions were not captured by watching an visual film. The few studies with deaf participants that did show activations in the primary auditory cortex of the deaf involved fast executive processing, such as task-switching (Manini, et al, 2021) and double flash detection (Karns et al, 2012). In the current study, the movie was viewed passively.…”

“…These include perceptual tasks, such as peripheral vision (Finney et al, 2001), motion perception (Scott et al, 2014;Shiell et al, 2016), visual motion discrimination (Benetti et al, 2021a) and temporal and spatial sequence processing (Bola et al, 2017;Zimmermann et al, 2021). Responses have also been found to various high-level functions, including working memory and executive control (Andin et al, 2021;Cardin et al, 2018;Twomey et al, 2017) (Manini et al, 2021).…”

Early deafness enhances responses of auditory cortices to non-auditory tasks, yet the nature of the reorganization is not well understood. Here, naturalistic stimuli were used to induce neural synchrony across early deaf and hearing individuals. Participants watched a silent animated film in an intact version and three versions with gradually distorted meaning. Differences between groups were observed in higher-order auditory cortices in all stimuli, with no significant effects in the primary auditory cortex. Comparison between levels of scrambling revealed a heterogeneity of function in secondary auditory areas. Both hemispheres showed greater synchrony for the intact movie than for low-level variants. However, the right hemisphere showed an increased inter-subject synchrony for the low-level movie variants, which was not present on the left. An event segmentation validated these results: the dynamics of the right secondary auditory cortex unfolded as shorter length events with more transitions than the left. It also uncovered a further left-right asymmetry: Only left-hemisphere patterns matched the patterns of the hippocampus, a brain region situated at the top of cortical hierarchy. Our results reveal how deaf subjects use their auditory cortex to process visual meaning.

“…Substantial evidence from studies on the blind shows that the visual cortex can be engaged in general language processing (Bedny et al, 2011;Lane et al, 2015), mathematical reasoning (Kanjlia et al, 2016), and nonverbal executive functions (Loiotile and Bedny, 2018). Moreover, a few recent studies indicate that the auditory cortex can exhibit similar flexibility and engage in higher cognitive functions, such as working memory (Ding et al, 2016;Twomey et al, 2017;Cardin et al, 2018) and executive functions (Manini et al, 2021).…”

The Extent of Task Specificity for Visual and Tactile Sequences in the Auditory Cortex of the Deaf and Hard of Hearing

et al. 2021

It has been proposed that the auditory cortex in the deaf humans might undergo task-specific reorganization. However, evidence remains scarce as previous experiments used only two very specific tasks (temporal processing and face perception) in visual modality. Here, congenitally deaf/hard of hearing and hearing women and men were enrolled in an fMRI experiment as we sought to fill this evidence gap in two ways. First, we compared activation evoked by a temporal processing task performed in two different modalities, visual and tactile. Second, we contrasted this task with a perceptually similar task that focuses on the spatial dimension. Additional control conditions consisted of passive stimulus observation. In line with the task specificity hypothesis, the auditory cortex in the deaf was activated by temporal processing in both visual and tactile modalities. This effect was selective for temporal processing relative to spatial discrimination. However, spatial processing also led to significant auditory cortex recruitment which, unlike temporal processing, occurred even during passive stimulus observation. We conclude that auditory cortex recruitment in the deaf and hard of hearing might involve interplay between task-selective and pluripotential mechanisms of cross-modal reorganization. Our results open several avenues for the investigation of the full complexity of the cross-modal plasticity phenomenon.

Highlights. For the first time, the method of standardized low resolution electromagnetic tomography – sLORETA was used to assess the neurophysiological correlates of the success of cognitive rehabilitation using dual task to recover the brain functions affected by ischemia during cardiac surgery.The patients who were successfully rehabilitated have demonstrated lower postoperative values of resting state theta activity within the right hemisphere, indicating the transfer effect, which is an important component of successful cognitive rehabilitation.Aim. Visualization and monitoring of brain ischemia is important for the diagnosis of cerebrovascular diseases. The aim of the study was to evaluate the possibilities and applicability of the method of standardized low resolution electromagnetic brain tomography – sLORETA for analyzing brain electrical activity in patients undergoing cognitive rehabilitation using dual tasks to recover impaired brain functions during ischemia associated with cardiac surgery.Methods. The study included 16 male patients (45–75 years old) who were admitted for planned coronary artery bypass grafting (CABG) to the Clinic at the Research Institute for Complex Issues of Cardiovascular Diseases. Clinical and neurophysiological examinations were performed 2–3 days before CABG and 1 week after surgery. All patients underwent cognitive rehabilitation that started at postoperative day 3 or 4 and lasted until discharge, the outcome was assessed as well. Monopolar EEG (62 channels) was recorded at rest in a sitting position with eyes closed in a light- and noise-insulated room using a Neuvo SynAmps2 Amplifier. Data processing of EEG background activity for sLORETA analysis was performed using the EEGLAB in MATLAB software (The MathWorks, Natick, MA, USA). The sLORETA algorithms were used to calculate dynamic cross spectrum and current source density within the analyzed frequency range (4–6 Hz). Statistical analysis of current source density indicators was carried out by using the method of statistical non-parametric mapping in the sLORETA software package, and the difference between the current source density in the pre- and postoperative period (after cognitive rehabilitation) was calculated as well.Results. Cognitive rehabilitation was successful in 44% (7 patients) of cases. The differences have been revealed between the groups with successful and unsuccessful cognitive rehabilitation by using sLORETA. The group with unsuccessful cognitive rehabilitation demonstrated higher current source density estimates in theta rhythm compared with the successful rehabilitation group, it was most pronounced (t>- 8.42; p<0.004) in the right hemisphere – Brodmann area 22, temporal lobe and superior temporal gyrus.Conclusion. The sLORETA method demonstrated the positive effect of cognitive training on changes in the spatial patterns of brain activity in patients undergoing onpump CABG. The successful cognitive rehabilitation was associated with lower postoperative resting state theta activity within the right hemisphere, indicating the transfer effect, which is an important component of successful cognitive rehabilitation.
