Expériences et résultats sur une seconde, la figure IV.15 présente le calcul du sixième niveau de détail par l'intermédiaire de la SWT (d6) ainsi que la détection effectuée par NeuroBetaMed_XL ,
amplitude des PAs est plus faible Nous sommes à la 220 ème seconde de notre enregistrement, et l'activité et les cellules commencent à s'épuiser rendant les PAs difficiles à distinguer (figure IV.16.A) Afin de mieux détecter les PAs, nous appliquons un filtre passe-bas logiciel avec un seuil fixé manuellement depuis le début de l'expérience (figure IV, Enfin nous comparons ces résultats avec ceux fournis par notre circuit (figure IV.16.D) ,
PAs sur 8 ont été détectés alors que le seuil est réglé au plus près possible du niveau de bruit Ce réglage a généré de nombreux faux positifs sur l'ensemble de l'expérience Avec NeuroBetaMed_XL, 7 PAs sont détectés. Ce résultat aurait pu être meilleur si nous avions baissé légèrement le gain du seuil durant l'expérience sans engendrer de faux positifs, Au bilan même quand les PAs diminuent d'amplitude, ils sont toujours détectés par notre circuit alors qu'avec un filtrage conventionnel ,
nous nous avons fait des études statistiques, dont nous montrons un exemple ici sur 5 minutes d'enregistrement (figure IV ,
par l'ajout d'une connexion spéciale, pour être utilisé sur des signaux neuronaux mesurés à partir des électrodes fabriquées par l'ESYCOM et provenant de la moelle épinière ex vivo de souris (projet HYRENE) Nous avons pu tester NeuroBetaMed_XL, sans tissu vivant en enregistrant des impulsions électriques envoyées par le biais d'une électrode de stimulation ,
