“…For comparison of rs-fMRI data between a patient and a healthy control, we analyzed temporal SNR (tSNR) of each scanner, which can be used to determine the SNR of fMRI time series. [ 16 , 17 ] We confirmed that there was no significant difference in tSNR between 2 scanners using modified t test ( t = -1.411, P = .097).…”

Rationale: Cortical deafness is a rare auditory dysfunction caused by damage to brain auditory networks. The aim was to report alterations of functional connectivity in intrinsic auditory, motor, and sensory networks in a cortical deafness patient. Patient concerns: A 41-year-old woman suffered a right putaminal hemorrhage. Eight years earlier, she had suffered a left putaminal hemorrhage and had minimal sequelae. She had quadriparesis, imbalance, hypoesthesia, and complete hearing loss. Diagnoses: She was diagnosed with cortical deafness. After 6 months, resting-state functional magnetic resonance imaging (rs-fMRI) and diffuse tensor imaging (DTI) were performed. DTI revealed that the acoustic radiation was disrupted while the corticospinal tract and somatosensory track were intact using deterministic tracking methods. Furthermore, the patient showed decreased functional connectivity between auditory and sensorimotor networks. Interventions: The patient underwent in-patient stroke rehabilitation therapy for 2 months. Outcomes: Gait function and ability for activities of daily living were improved. However, complete hearing impairment persisted in 6 months after bilateral putaminal hemorrhagic stroke. Lessons: Our case report seems to suggest that functional alterations of spontaneous neuronal activity in auditory and sensorimotor networks are related to motor and sensory impairments in a patient with cortical deafness.

“…The acquisition of both fMRI and dMRI can also be bolstered by using multiband echo planar imaging (Feinberg & Yacoub, 2012;Feinberg et al, 2013) allowing the acquisition of multiple volumes in a shorter amount of time window. This therefore provides increased time points for increased correlation reliability, but at the expense of reduced contrast to noise ratio, and sensitivity to motion, highlighting the need to scan for longer (Reynaud et al, 2017;Seo et al, 2017).…”

The human brain is a dynamic network comprised of elements which are structurally connected and functionally interactive. A tight structure-function relationship is vital for this system to produce seamless cognition and behaviour. Brain injuries due to either neurological disease or single-event injuries alter the dynamics of normal structure-function interaction, resulting in poor neurobehavioural outcomes for patients. This scoping review is a synthesis of recent progress in understanding how brain injuries alter the structure-function relationship. We identified 16 studies that investigated the structure-function relationship in brain-injured cohorts, using fMRI and either T1-weighted or diffusion-weighted MRI to calculate, respectively, grey matter density or structural connectivity. Overall, a reduced structure-function relationship was found in brain-injured patients relative to healthy controls. This weakened relationship coincided with impaired cognition. Structural and functional MRI information should also be reconciled into suitable graph theoretical frameworks such as the multilayer network approach
