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.

From hearing colors to seeing ultraviolet, is enhancement the future of human senses? https://theswaddle.com/from-hearing-colors-to-seeing-ultraviolet-is-enhancement-the-future-of-human-senses/

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."

Awesome sketch on the #ImagingNeuroscience editor rebellion. I seriously hope more editors will have the courage and follow suit. (Looking at you Nature journals).

Debate: Why not scientism?

Science is not the only form of knowledge but it is the best, being the most successful epistemic enterprise in history.

Philosophy is dead,’ Stephen Hawking once declared, because it ‘has not kept up with modern developments in science, particularly physics.’
The response from some philosophers was to accuse Hawking of ‘scientism'

There was a paper pinned on the wall in the lift at work today. I tapped my #Envision glasses to detect text on the paper. Turned out to be a concert ad, in Estonian. Since the Envision glasses do have GPT4, I told them to translate it into english, which they did. Asked the glasses for details about the venue and it described where the concert takes place, however was unable to tell me the address, since it wasn’t featured on the ad. Felt quite empowering. I know I can do most of those things via different apps on my phone, but it feels somewhat magical to just do it all by tapping and talking to your glasses.
