Correlation in functional MRI activity between spatially separated brain regions can fluctuate dynamically when an individual is at rest. These dynamics are typically characterized temporally by measuring fluctuations in functional connectivity between brain regions that remain fixed in space over time. Here, dynamics in functional connectivity were characterized in both time and space. Temporal dynamics were mapped with sliding-window correlation, while spatial dynamics were characterized by enabling network regions to vary in size (shrink/grow) over time according to the functional connectivity profile of their constituent voxels...

In recent years, with the rapid development of machine learning techniques,the deep learning algorithm has been widely used in one-dimensional physiological signal processing. In this paper we used electroencephalography (EEG) signals based on deep belief network (DBN) model in open source frameworks of deep learning to identify emotional state (positive, negative and neutrals), then the results of DBN were compared with support vector machine (SVM). The EEG signals were collected from the subjects who were under different emotional stimuli, and DBN and SVM were adopted to identify the EEG signals with changes of different characteristics and different frequency bands...

In recent years, neuroimaging research in cognitive neuroscience has increasingly used multivariate pattern analysis (MVPA) to investigate higher cognitive functions. Here we present DDTBOX, an open-source MVPA toolbox for electroencephalography (EEG) data. DDTBOX runs under MATLAB and is well integrated with the EEGLAB/ERPLAB and Fieldtrip toolboxes (Delorme and Makeig 2004; Lopez-Calderon and Luck 2014; Oostenveld et al. 2011). It trains support vector machines (SVMs) on patterns of event-related potential (ERP) amplitude data, following or preceding an event of interest, for classification or regression of experimental variables...

Recent studies have shown the value of using deep learning models for mapping and characterizing how the brain represents and organizes information for natural vision. However, modeling the relationship between deep learning models and the brain (or encoding models), requires measuring cortical responses to large and diverse sets of natural visual stimuli from single subjects. This requirement limits prior studies to few subjects, making it difficult to generalize findings across subjects or for a population...

PURPOSE: Many clinical contexts require the acquisition of multiple positron emission tomography (PET) scans of a single subject, for example to observe and quantify changes in functional behaviour in tumours after treatment in oncology. Typically, the datasets from each of these scans are reconstructed individually, without exploiting the similarities between them. We have recently shown that sharing information between longitudinal PET datasets by penalising voxel-wise differences during image reconstruction can improve reconstructed images by reducing background noise and increasing the contrast-to-noise ratio of high activity lesions...

BACKGROUND: Fluent word reading is a key characteristic of skilled reading, yet most children with reading disorders have impaired word-reading skills. Previous research has demonstrated that multi-component interventions targeting phonemic awareness and the alphabetic principle are effective for children with reading disorders. However, about 25% of children fail to respond to these interventions. While it has been difficult to isolate the active ingredient, the findings of some studies suggest that tasks targeting phonological recoding and orthographic processing are essential elements in improving decoding...

OBJECTIVE: To assess the effect of distance caregiver coaching on skill acquisition of a child with traumatic brain injury. Interactions between caregivers and persons with brain injury may play a critical role in the rehabilitation process, and coaching caregivers is one method that may foster more positive functional outcomes for the individual as caregiver skills may generalize across domains. METHOD: This study utilised a single-subject, multiple baseline across behaviours design to examine the effects of caregiver behaviours on skill acquisition by a child with a traumatic brain injury...

There are many prosthetic feet (Pfeet) on the market, and those in the same category do not necessarily have the same properties. We assessed three different Pfeet in terms of gait patterns on various terrains, balance and walking speed in a randomized double-blind controlled single-subject multiple-rater clinical trial. The patient was a 43-year old man who was an active prosthesis user and was amputated at transtibial level because of injury 17 years ago. One Solid Ankle Cushion Heel and two Dynamic Elastic Response (DER) Pfeet were tried six times in random order...

Analysis of running mechanics has traditionally been limited to a gait laboratory using either force plates or an instrumented treadmill in combination with a full-body optical motion capture system. With the introduction of inertial motion capture systems, it becomes possible to measure kinematics in any environment. However, kinetic information could not be provided with such technology. Furthermore, numerous body-worn sensors are required for a full-body motion analysis. The aim of this study is to examine the validity of a method to estimate sagittal knee joint angles and vertical ground reaction forces during running using an ambulatory minimal body-worn sensor setup...

Many of an individual's historically recorded personal measurements vary over time, thereby forming a time series (e.g., wearable-device data, self-tracked fitness or nutrition measurements, regularly monitored clinical events or chronic conditions). Statistical analyses of such n-of-1 (i.e., single-subject) observational studies (N1OSs) can be used to discover possible cause-effect relationships to then self-test in an n-of-1 randomized trial (N1RT). However, a principled way of determining how and when to interpret an N1OS association as a causal effect (e...
