The perception of silence pnas.org/doi/10.1073/pnas.2301 "Silence is truly perceived, not merely inferred"; but no "OFF cells" like with darkness detection in the human retina?

Do we actually "hear" silence? scientificamerican.com/article "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.

Ahhh, the (Eurasian) Robins are out in force today. Here is one of many posing in a nearby shrub as I walked past

@seeingwithsound I see your point on how AI generated information could negatively affect such technology. It seems some sort of built-in fact check is needed, but not sure how it can be implemented.

@JimsPhotos Do you know what bird that is? I recently saw a similar one while traveling.

Even though I am relatively new to and , what I like about the 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 . In order to populate a , the onus is upon the user to follow liberally, as there is no all-seeing, all-knowing to do the work.

Auditory cortex conveys non-topographic sound localization signals to visual cortex biorxiv.org/content/10.1101/20

Auditory cortex conveys non-topographic sound localization signals to visual cortex.

Perception requires binding spatiotemporally congruent multimodal sensory stimuli. The auditory cortex (AC) sends projections to the primary visual cortex (V1), which could provide signals for binding spatially corresponding audio-visual stimuli. However, it is unknown whether AC inputs in V1 encode sound location. We used dual-color two-photon axonal calcium imaging and an array of speakers to measure the auditory spatial information that AC transmits to V1. We found that AC relays information about the location of ipsilateral and contralateral sound sources to V1. Sound location could be accurately decoded by sampling AC axons in V1, providing a substrate for making location-specific audiovisual associations. However, AC inputs were not retinotopically arranged in V1, and audio-visual modulations of V1 neurons did not depend on the spatial congruency of the sound and light stimuli. The distributed, non-topographic sound localization signals provided by AC might allow the association of specific audiovisual spatial patterns in V1 neurons. ### Competing Interest Statement The authors have declared no competing interest.

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'
