The stainless steel sculpture "Neuron" by Roxy Paine. Outside the Museum of Contemporary Art, Sydney for the 17th Biennale.
Stroking the leg, and watching the electrical spikes in the nervous system.
As I rubbed the pinned cockroach leg hairs, the neuron spikes were visible on the iPad. They have a simple single neuron per hair system to jack into.
We then ran it backward, and got the leg to dance to a hip hop tun. I wanted to teach it jiu-jitsu. =)
Neurons receive input from other neurons through synapses, most of which are located along the dendrites on tiny projections called spines.
Two NIH-funded studies in mice are offering a possible answer about what makes sleep essential to good health. The two research teams used different approaches to reach the same conclusion: the brain’s neural connections grow stronger during waking hours, but scale back during snooze time. This sleep-related phenomenon apparently keeps neural circuits from overloading, ensuring that mice (and, quite likely humans) awaken with brains that are refreshed and ready to tackle new challenges.

A neuron from the AIs of the future?
This has NOT been photoshopped.
Was created using long exposure and various LED lights.

A fluorescent microscopic image of neural precursors generated from human embryonic stem cells. The neural cell bodies are visible in red and the nuclei in blue.
This photo was taken in the lab of Xianmin Zeng at the Buck Institute for Age Research.

During last year's Biennale, Roxy Paine's work, called Neuron, was given a deservably prominent position on the forecourt of the Museum of Contemporary Art
Human embryonic stem cells differentiated into dopaminergic neurons after being exposed to a mix of synthetic compounds. Red indicates the protein beta-tubulin III, which is found in the dopaminergic neurons that degenerate in Parkinson's disease. Blue indicates nuclei. This work could lead to more efficient ways of generating dopaminergic neurons to study the origins and possible treatments for Parkinson's disease.
This photo was taken by Andrei Kochegarov in the lab of Michael Pirrung at the University of California, Riverside.

Neurones pyramidaux du cortex cérébral, visualisés chez la souris modèle pour la maladie de Huntington 21 jours après la naissance. Une semaine après la naissance, des altérations de morphologie et d'activité apparaissent dans ces neurones, mais à 21 jours ces altérations ne sont plus visibles. Leur activité et leur morphologie sont alors similaires pour un temps à celles de souris saines.

Si les symptômes de la maladie de Huntington se manifestent généralement entre 30 et 50 ans, des travaux ont montré que la maladie impactait le développement cérébral dès le stade embryonnaire. Une équipe de chercheuses et chercheurs de l’Inserm et de l’Université Grenoble Alpes, au sein du Grenoble Institut des neurosciences, a mis en évidence, chez la souris, un impact de la maladie sur la qualité de la transmission nerveuse dans certains neurones très tôt après la naissance avec des conséquences anatomiques et comportementales. Ces travaux parus dans Science en 2022 montrent aussi l’intérêt d’un traitement précoce avec une molécule favorisant la transmission nerveuse, qui restaure les défauts néonataux observés et retarde l’apparition de la maladie à l’âge adulte. Ils ouvrent ainsi de nouvelles pistes de recherche sur la prise en charge thérapeutique de la maladie de Huntington chez l’humain.

Whetstone, a software tool that sharpens the output of artificial neurons, has enabled neural computer networks to process information up to a hundred times more efficiently than the current industry standard, say the Sandia researchers who developed it.
The software greatly reduces the amount of circuitry needed to perform autonomous tasks, and is expected to increase the penetration of artificial intelligence into markets for mobile phones, self-driving cars and automated interpretation of images.

More experimental Photography...
No lights were used in this photo, no editing was done, xcept a crop
light is from self luminescence chemicals inside a glow in the dark light stick (the ones you break an shake) poured onto a those plasticky bubbles that we used to blow up when we were kids... apparently the chemicals poured onto bubbles make them shrink an go webby an gooey like!!!
loved these shots....shot in complete darkness
