“…It is important to note that the calculated baselines cannot be interpreted as a fixation baseline condition because we did not include null-events in our design.

“…For instance, the object-selective lateral occipital cortex (LO), and a subregion in the fusiform gyrus (FG) are both consistently active when individuals grasp or see man-made tools, animal models, musical instruments or toys relative to non-object control stimuli (Amedi et al, 2001(Amedi et al, , 2002Kassuba et al, 2011). In addition, more dorsal regions within the intraparietal sulcus (IPS) have been shown to be more generally involved in a wide range of processes that involve the visual and haptic sense.…”

IMPORTANCE There is a dearth of studies that examine the association between poorer hearing and change in cerebral white matter (WM) microstructure.OBJECTIVE To examine the association of poorer hearing with baseline and change in WM microstructure among older adults. DESIGN, SETTING, AND PARTICIPANTSThis was a prospective cohort study that evaluated speech-in-noise, pure-tone audiometry, and WM microstructure, as measured by mean diffusivity (MD) and fractional anisotropy (FA), both of which were evaluated by diffusion tensor imaging (DTI) in 17 WM regions. Data were collected between October 2012 and December 2018 and analyzed between March 2019 and August 2019 with a mean follow-up time of 1.7 years. The study evaluated responses to the Baltimore Longitudinal Study of Aging among 356 cognitively normal adults who had at least 1 hearing assessment and DTI session. Excluded were those with baseline cognitive impairment, stroke, head injuries, Parkinson disease, and/or bipolar disorder.EXPOSURES Peripheral auditory function was measured by pure-tone average in the better-hearing ear. Central auditory function was measured by signal-to-noise ratio score from a speech-in-noise task and adjusted by pure-tone average. MAIN OUTCOMES AND MEASURESLinear mixed-effects models with random intercepts and slopes were used to examine the association of poorer peripheral and central auditory function with baseline and longitudinal DTI metrics in 17 WM regions, adjusting for baseline characteristics (age, sex, race, hypertension, elevated total cholesterol, and obesity). RESULTSOf 356 cognitively normal adults included in the study, the mean (SD) age was 73.5 (8.8) years, and 204 (57.3%) were women. There were no baseline associations between hearing and DTI measures. Longitudinally, poorer peripheral hearing was associated with increases in MD in the inferior fronto-occipital fasciculus (β = 0.025; 95% CI, 0.008-0.042) and the body (β = 0.050; 95% CI, 0.015-0.085) of the corpus callosum, but there were no associations of peripheral hearing with FA changes in these tracts. Poorer central auditory function was associated with longitudinal MD increases (β = 0.031; 95% CI, 0.010-0.052) and FA declines (β = −1.624; 95% CI, −2.511 to −0.738) in the uncinate fasciculus.CONCLUSIONS AND RELEVANCE Findings of this cohort study suggest that poorer hearing is related to change in integrity of specific WM regions involved with auditory processing.

Verbal Working Memory‐Balance program training alters the left fusiform gyrus resting‐state functional connectivity: A randomized clinical trial study on children with dyslexia

Sufficient activation of the left fusiform gyrus is important in reading ability acquisition due to its role in reading and naming, working memory (WM), and balance tasks. Recently, a newly‐designed training program, Verbal Working Memory‐Balance (VWM‐B), has been evaluated on children with dyslexia, and its positive effects were shown on reading ability, WM capacity, and postural control. In the present study, we aimed to estimate the functional connectivity alterations of the left fusiform gyrus following training by the VWM‐B. Before and after 15 sessions of training, the fMRI and other tools data were collected on a sample of children with dyslexia, who were allocated into two control and experiment groups. Data analyses showed the increased functional connectivity of the left fusiform gyrus between the left anterior temporal fusiform cortex, left and right Crus II regions of the cerebellum, and the left middle frontal gyrus. Moreover, VWM‐B training significantly improved the reading and naming ability, WM capacity, and postural control of participants in the experiment group in comparison to the control. The current study findings emphasize the critical role of the left fusiform gyrus in reading ability. Moreover, it provides evidence to support the existence of cerebellar deficits in dyslexia.
