Lately, the functional connectivity in human brain has been regarded and studied as a complex network using electroencephalography (EEG) signals. This means that the brain is studied as a connected system, where nodes represent different specialized brain regions and links or connections, represent communication pathways between the nodes. It is also fairly established that graph theory provides a variety of measures, methods and tools that can be useful to efficiently model, analyze and study an EEG network. In this article we study weighted and fully-connected brain networks, created from long-recorded EEG measurements that concern patients with focal and generalized epilepsy. We focus on the use of the well-known eigenvector centrality measure, which shows the influence of a node in a network and also constitutes the basis of the famous Google's PageRank algorithm. Our novel methodology reveals brain regions that might play a significant role before the occurrence of each epileptic seizure and also brain areas that might constitute the seed of the abnormal electrical activity that the human brain presents during epileptic seizures. Finally, we present and discuss the results and conclusions of our methodology, which demonstrates a standard EEG behavior in particular phases of the recording period.","PeriodicalId":72689,"journal":{"name":"Conference proceedings : ...

Most efforts have been directed towards studying the upper limb region of the motor cortex. Little has been done in the way of addressing lower limb motor cortical physiology. In this study, we implanted multiple microelectrode arrays along the central sulcus in the primary motor cortex of a macaque monkey. Using intracortical microstimulation, we identified neurons that evoked leg movements, either exclusively or mostly, and we studied their firing activity during a center-out arm movement task. We found that some of these neurons modulated their firing rate during arm movement. Surprisingly, we found that some of these neurons even had selective tuning to the direction of arm movement. We built a decoding model which was able to predict the direction of arm movement based on putative leg motor cortical firing activity significantly better than chance. These findings have interesting and surprising implications for understanding motor cortical physiology.","PeriodicalId":72689,"journal":{"name":"Conference proceedings : ...

In an attempt to gain a broader understanding of the CPR physiology and the elemental principles underlying the CPR outcomes, this study proposes a novel approach. The analysis is carried out in three major steps. First, an appropriate cardiovascular system model was adopted and simulated using real CPR data as the input. Next, a function was fitted to the input data in order to obtain an input function with controllable parameters. In the last step, the parameters of the obtained input function were optimized with respect to the objective function that was constrained by the simulated cardiopulmonary values of the model. The results of this preliminary analysis illustrate that the developed framework reflects the findings of numerous studies and shows that this innovative approach can have a great impact on the CPR research field.","PeriodicalId":72689,"journal":{"name":"Conference proceedings : ...

During the last decade, there was a growing interest in functional connectivity using surface-based analysis. However, the advantages of this approach against volume-based analysis in a data-driven model are unclear. In this study, we propose an independent component analysis based method to extract the resting-state networks directly on the cortical surface. The components associated with the subcortical regions are identified by multiple linear regressions between the signals in subcortical voxels and independent components time courses. The accuracy and stability of our method were evaluated using resampling statistics calculated on 76 healthy male subjects and compared to those obtained with a similar volume-based approach. Seven of the most representative resting-state networks reported in previous studies were identified and used to compare both approaches. Our findings suggest that surface-based approach combined with subcortical linear regression is more sensitive and reproducible than similar volume-based approach for the extraction of resting-state networks.","PeriodicalId":72689,"journal":{"name":"Conference proceedings : ...

However, the majority of patients are not diagnosed and an easier-to-use, lower-cost device for screening of SAS is needed compared to the existing multimodal devices. In this study, we developed and tested a method to estimate the apnea-hypopnea index (AHI), which is the measure of severity of SAS, only from an accelerometer signal measured on the chest. Simultaneous recordings of overnight sleep polysomnography and accelerometer signal were conducted for 50 participants. Three prediction variables were extracted from the accelerometer signal: (i) power of vibration caused by snoring, (ii) variability of frequency of vibration caused by snoring, and (iii) the number of times of rapid changing in the amplitudes of the chest movement accompanied by breathing efforts. Multiple regression analysis was applied to estimate AHI, and the agreement between estimated AHI and true AHI was evaluated by a leave-one-out strategy. The correlation coefficient between the estimated AHI and the true AHI was 0.759, and the sensitivity and the specificity with the threshold of AHI=15 were 83.3% and 88.5%, respectively. Considering the fact that our method requires only an accelerometer to estimate AHI, it has the potential to be a cost-effective way of screening SAS patients.","PeriodicalId":72689,"journal":{"name":"Conference proceedings : ...
