Humans have been hunting for sex-based differences in the brain dating back to at least ancient Greece. Yet a scientist observing a female and male brain in a lab can’t tell them apart. "I'm not aware of any measure you can make of the human brain where the male and female distributions don't overlap," Dr. Armin Raznahan told Live Science. That said, the question of how male and female brains differ may still matter. @LiveScience has more:

Whoa

A new study shows that #microplastics are making their way into human #brains —w/potentially dangerous effects on people’s #health & mental #acuity.

A paper published Mon in #NatureMedicine found that the tiny fragments of #plastic are passing the blood-brain barrier & into human brains, & the amount of #microplastics in the #brain appears to be increasing over time. There were 50% more fragments in brains analyzed in 2024 than in 2016.

The EEG quickly evolved from a scientific curiosity to a mainstream clinical tool. Now 100 years old, it’s an invaluable window into the activity of the brain

My mate Liam recently sent me this, to get my take on it.

Basically, assuming the results quoted are valid (never a 100% guarantee neuroscience), the 'interpretation' posted is a WILD leap of logic and speculation, and a drastic misunderstanding of how anything works.

I'll do an #introduction since we're back in a place where running into non-celebrity strangers is possible.

Things I like:

But mostly I'm sticking with using social media to share what I had for lunch.
