However, in order to be able to use the brain activity, the related psychophysiological data has to be processed and analyzed with sophisticated signal processing and machine learning methods. Usually these methods have to be calibrated with subject-specific data before they can be used. Since future systems that implement these methods need to be portable to be applied more flexible tight constraints regarding size, power consumption and computing time have to be met. Field Programmable Gate Arrays (FPGAs) are a promising solution, which are able to meet all the constraints at the same time. Here, we present an FPGA-based mobile system for signal processing and classification. In addition to other systems, it is able to be calibrated and adapt at runtime, which makes the acquisition of training data unnecessary.","PeriodicalId":167011,"journal":{"name":"International Congress on Neurotechnology, Electronics and Informatics","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124890873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this aim, Neurorobotics is gaining relevance as a way to translate the biological principles into “intelligent” machines. The result of this process is twofold: i) validating the biomechanical and neural control principles found in humans, and ii) developing more effective rehabilitation devices and strategies. In this paper, some of the main challenges of this process will be presented, with particular emphasis on the implications in diagnostic and rehabilitation of walking. As a first step in this direction, the European project H2R aims at developing a humanoid that includes the most relevant biological principles of human locomotion and posture.

In this article we consider Brain Computer Interfaces (BCI) as a new interaction mechanism that could be used in serious games to improve their rehabilitation activity thanks to the ability of neurofeedback to stimulate the cortical plasticity. We present the brief state-of-the-art of BCI serious games and the factors to be considered in order to develop this particular kind of software that could be highly complex and require experts with different knowledge and skills. We propose a new approach based on the detection of focus features in the game activity. We introduce a system able to assess the Alpha band variations in particular game tasks. Our initial target users are children with cerebral palsy and motor disabilities. The system is currently under evaluation with control users before to be operated with the target users in rehabilitation centers.","PeriodicalId":167011,"journal":{"name":"International Congress on Neurotechnology, Electronics and Informatics","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123012560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the vast complexity of such a nervoussystem has made it very difficult to fully understand even the most basic of functions such as movement andlearning and accordingly there has been increasing attention paid to the development of emulations ofsimpler systems. One such system is the C. elegans nematode, which has been widely studied in recentyears and there now exists a vast wealth of biological knowledge about its nervous structure, function andconnectivity. The Si elegans EU FP7 project aims to develop a Hardware Neural Network (HNN) toaccurately replicate the C. elegans nervous system behaviour to enable neuroscientists to better understandthese basic functions. To fully replicate the C. elegans biological system requires powerful computingtechnologies, based on parallel processing, for real-time computation and therefore will use FieldProgrammable Gate Arrays (FPGAs) to achieve this. In this paper an overview of the complete hardwaresystem required to fully realise Si elegans is presented along with an early small scale implementation of thehardware system.","PeriodicalId":167011,"journal":{"name":"International Congress on Neurotechnology, Electronics and Informatics","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127855093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A step further, we describe an effective solution, freely available on line and already in use to validate functional models of the brain. This solution is a digital platform where the brainy-bot implementing the model to study is embedded in a simplified but realistic controlled environment. From visual, tactile and olfactory input, to body, arm and eye motor command, in addition to vital somesthetic cues, complex survival behaviors can be experimented. The platform is also complemented with algorithmic high-level cognitive modules, making the job of building biologically plausible bots easier.","PeriodicalId":167011,"journal":{"name":"International Congress on Neurotechnology, Electronics and Informatics","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124698317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three types of neural networks were investigated: Elman, cascadeforward and feed-forward back propagation. We assessed the performance of the models using the Receiver Operating Characteristic (ROC) curve, particularly the area under the ROC curves (AUC), and statistically compare the cross validated estimate of the AUC of different models.

This pilot study also aims to demonstrate that the tool is suitable for measuring biomechanical data while allowing EMG measurements, proving it as a useful tool during gait assessment and rehabilitation. Gastrocnemius Medialis activation presents slightly higher amplitude with higher assistances, so the subjects performed a higher range of motion gait pattern. Tibialis Anterior EMG activation presents consistent data with previous studies. Ankle angle at lower assistances makes the robot force less the subject to reach the imposed gait pattern, and so the range of motion diminishes. Regarding ankle angular velocity, at higher assistances, higher velocities are reached. The torque between the subjects foot and the robot.
