The uniqueness of this approach is in mapping topographic maps to the cortex surface of the brain based on projections of the results obtained from the skull surface. MRI is known to provide information about the anatomical structure of the brain, while optical topography system (OTS) displays the changes in the cerebral blood flow in the form of a topographic image. The experiment is based on a repeated finger-tapping task using seven volunteers at Miami Children Hospital. The integration of both modalities reveal excellent prospects in localizing the activation that is seen by (OTS) on the 3D brain models constructed from MRI slices. This task demands the development of a computer program that will first identify the region on the 3-D head model from which the topographic image generated by OTS was taken. Second, the topographic images are registered to the 3-D head model. In order to validate our findings, a comparison is made between the fiducial markers (vitamin E) placed on the patients head during the MRI test to localize the probes location and an automated computer program that will detect the probes position. Using the brain extraction tool (BET), the warped topographic maps are then projected onto the cortex surface of the extracted brain. The proposed OTS-MRI integration is deemed an important field in the neuroscience, allowing investigation of a wide range of motor, sensory, and cognitive functions, as well as providing key information about anatomical structure of the brain","PeriodicalId":113815,"journal":{"name":"Conference Proceedings. 2nd International IEEE EMBS Conference on Neural Engineering, 2005.","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132319043","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}

Electrodes were placed for stimulation of hip and knee extensors, and for hip abduction and adduction. Standing and walking were achieved through constant stimulation to the implanted muscles, allowing a swing through gait pattern with an assistive device. After training with FES, subjects were tested in 3 upright mobility activities on an annual basis, which were scored based upon completion time and level of independence. Follow-up data were available for 7 of 10 subjects and spanned 1 to 5 years. Of the 21 activities tested (7 subjects times 3 activities), independence level with FES was improved or maintained in 15 cases (71%). For the 6 remaining cases (29%), moderate to minimal assistance was required at follow-up where no assistance was needed initially. Completion times were maintained or improved over follow-up in 17 of the 21 cases (81%).

This paper demonstrates the use of microelectrode arrays for mapping extracellular spike activity and local-field potentials in the lumbar spinal cord of rats. Locomotion was studied in acute decerebrate rats by stimulation of the mesencephalic locomotor region (MLR) to induce stepping. Neural-ensemble activity during stepping was correlated with electromyograms (EMG) from ankle flexors and extensors. To visualize the activity, spatiotemporal population maps were generated from the recorded step cycles. These results will shed light on the organization of locomotor pattern generating circuits and identify active regions for stimulation. In future studies, we will test patterned electrical stimulation of the identified hotspots in spinal-cord-transected rats. These efforts will be directed towards the development of a functional stimulator for locomotion in paralyzed patients","PeriodicalId":113815,"journal":{"name":"Conference Proceedings. 2nd International IEEE EMBS Conference on Neural Engineering, 2005.","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115537663","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}
