Íomháú athshondais mhaighnéadaigh feidhmeach

Tomhaiseann íomháú athshondais mhaighnéadaigh feidhmeach nó IAM feidhmeach (IAMf) gníomhaíocht inchinne trí athruithe a bhaineann le sreabhadh fola a bhrath.^[1] Braitheann an teicníc seo ar an bhfíric go bhfuil sreabhadh fola cheirbreach agus gníomhachtú néarónach cúpláilte. Nuair a bhíonn limistéar den inchinn in úsáid, méadaíonn an sreabhadh fola chuig an réigiún sin freisin.^[2]
