Clustered synapses develop in distinct dendritic domains in visual cortex before eye opening (in mice) https://www.biorxiv.org/content/10.1101/2023.03.02.530772v1 "presumably to equip dendrites with computational modules for high-capacity sensory processing."

"The THREE AGES OF WATER is a significant work on the critical topic of water. It’s historically rich and a scientifically accessible account of the water-human nexus over millennia, with a look at the future."

The perception of silence https://www.pnas.org/doi/10.1073/pnas.2301463120 "Silence is truly perceived, not merely inferred"; but no "OFF cells" like with darkness detection in the human retina?

Do we actually "hear" silence? https://www.scientificamerican.com/article/do-we-actually-hear-silence/ "An experiment tests whether our ears hear silent intervals in the same way they hear music or noise."

Metronomes started randomly synchronize after a short period of time as they influence each other through the side-to-side motion of their shared base.

Even though I am relatively new to #qoto and #mastodon, what I like about the #fediverse is its decentralised nature. I know that some will find this aspect quite disconcerting. Due to its nature, one is empowered to become one's own #algorithm. In order to populate a #timeline, the onus is upon the user to follow #hashtags liberally, as there is no all-seeing, all-knowing #algorithm to do the work.

" It is hard to imagine that before Pat’s research, the PFC was widely considered a “silent” brain area that neurosurgeons could lesion with impunity (as long as they did not damage Broca’s area), and the PFC was not thought to be a proper topic for scientific research."
