{"product_id":"2940156912841","title":"Functional magnetic resonance imaging","description":"Functional magnetic resonance imaging or functional MRI (fMRI) is a functional neuroimaging procedure using MRI technology that measures brain activity by detecting changes associated with blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases. The primary form of fMRI uses the blood-oxygen-level dependent (BOLD) contrast, discovered by Seiji Ogawa.","brand":"Charles Hunter","offers":[{"title":"Default Title","offer_id":47083719033072,"sku":"2940156912841","price":1.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940156912841_p0.jpg?v=1764093061","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940156912841","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
