Systems Neuroscience Using fMRI: Studying the Brain to Understand the Mind

Idan Blank, a post-doctoral researcher at MIT, explains how MRI and fMRI work, and highlights some important principles for the design fMRI experiments that examine functional specialization in the brain. These principles are illustrated through two fMRI studies. The first reveals brain regions that are active when subjects perform intuitive physical inference, and the second identifies patterns of brain activity suggesting that imagining a recent social break-up is associated with physical pain.

The “objection “ fails to understand or oblivious to a very basic (foundational ) concept in peripheral (vs. Lungs) tissue oxygenation; the Bohr-Haldane Effect. ..basic science 101 (physiology), anyone?😊

Wow, how is fMRI meaningful at all as a measure of brain activity? I seem to have missed that part😅 By definition neuronal firing (down its axon); APs, like EPSP, ISPS? Even if you summate and average all dendritc inputs in a particular region, if that’s all it can do, does not tell us neuronal firing or brain activity in any meaningful sense, not even remotely close. And big medical institutions use/rely on fMRI to confirm brain activity or not to pull the plug on someone. So depressing
