En abaissant significativement les seuils de d\u00e9tection et de tol\u00e9rance, l’axe\u00a0S1-VPL agit comme un v\u00e9ritable modulateur capable d’amplifier le signal sensoriel et de produire une sensibilit\u00e9 accrue.\u00a0<\/p>\n
\u00abCes d\u00e9couvertes modifient notre compr\u00e9hension du r\u00f4le de ces structures, qui ne sont pas de simples relais passifs, mais des acteurs dynamiques capables d’amplifier le signal douloureux, un m\u00e9canisme souvent observ\u00e9 dans la douleur chronique\u00bb, pr\u00e9cise Pierre Rainville, chercheur au CRIUGM, professeur au D\u00e9partement de stomatologie de l’Universit\u00e9 de Montr\u00e9al et coauteur de l’\u00e9tude.<\/p>\n
\u00abLe fait que nous avons pu provoquer une hypersensibilit\u00e9 plut\u00f4t qu’une analg\u00e9sie souligne la nature bidirectionnelle de ce r\u00e9seau neuronal et la puissance de la stimulation par ultrasons\u00bb, ajoute le Dr\u00a0Monchi.<\/p>\n
Il conclut: \u00abNos travaux d\u00e9montrent que la technologie par ultrasons permet d’atteindre une pr\u00e9cision in\u00e9dite pour moduler l\u2019activit\u00e9 de structures profondes du cerveau sans recourir \u00e0 la chirurgie. Cela ouvre de nouvelles voies pour comprendre comment le cerveau traite la douleur, une \u00e9tape importante avant de proposer de nouveaux traitements.\u00bb<\/p>\n","protected":false},"excerpt":{"rendered":"En abaissant significativement les seuils de d\u00e9tection et de tol\u00e9rance, l’axe\u00a0S1-VPL agit comme un v\u00e9ritable modulateur capable d’amplifier…\n","protected":false},"author":2,"featured_media":82241,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[82],"tags":[12,13,18,17,32859,2453,32860,32854,32858,12458,10487,32856,32857,86,32852,32853,32855,865,87,2604],"class_list":{"0":"post-82240","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-sante","8":"tag-be","9":"tag-be-fr","10":"tag-belgique","11":"tag-belgium","12":"tag-centre-de-recherche-de-linstitut-universitaire-de-geriatrie-de-montreal","13":"tag-cerveau","14":"tag-criugm","15":"tag-departement-de-radiologie","16":"tag-departement-de-stomatologie","17":"tag-douleur","18":"tag-faculte-de-medecine","19":"tag-faculte-de-medecine-dentaire","20":"tag-fmd","21":"tag-health","22":"tag-oury-monchi","23":"tag-pierre-rainville","24":"tag-radio-oncologie-et-medecine-nucleaire","25":"tag-recherche","26":"tag-sante","27":"tag-technologie"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@be_fr\/116444682443989670","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/posts\/82240","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/comments?post=82240"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/posts\/82240\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/media\/82241"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/media?parent=82240"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/categories?post=82240"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/be-fr\/wp-json\/wp\/v2\/tags?post=82240"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
