Question

Clinical ability to view blood flow throughout the brain is achieved by:

Trans-cranial Magnetic Stimulation;
Functional MRI;
EEG;
Elicitation of cranial nerve X reflex

Answer 1

Clinical observation of cerebral blood flow is primarily achieved through functional MRI (fMRI), which maps brain activity by measuring blood flow and oxygenation changes.

Step-by-step explanation:

The clinical ability to view blood flow throughout the brain is achieved by functional MRI (fMRI). This advanced imaging technique is crucial in neuroscience for mapping brain activity, including thought processes and motor control. It works by detecting changes in blood flow, where increased neuronal activity leads to an increased demand for oxygen. This, in turn, changes the magnetic properties of blood hemoglobin, thus allowing fMRI to measure and map the activity through a blood oxygen-dependent signal.
