40 percent of MRI signals misinterpreted

Interpretation of numerous MRI data may be incorrect: blood flow is not a reliable indicator of brain activity.

For Trump's current cognitive state there's another Texasism that might apply.

is showing signs he’s taking the #Alzheimers disease drug #Leqembi

“The Alzheimer’s drug Leqembi is administered through an infusion
(for example, through the hand)

Can cause swelling, bleeding, or fluid leakage in the brain, requiring regular #MRI

Alzheimer's disease is a specific brain disease that causes a gradual decline in memory and cognitive functions, while dementia is a broader term that describes a range of symptoms affecting memory, thinking, and behavior. Alzheimer's is the most common type of dementia, but there are other forms as well.

One of this article's many great points: Using #GenAI is a "metacognitive mirage".

> When participants used #ChatGPT to draft essays, brain scans revealed [-47%] in neural connectivity across regions associated with memory, language, and critical reasoning. Their brains worked less, but they felt just as engaged
> Students aren’t just learning less; their brains are learning not to learn.
