Artwork based on nervous system, neurons and neuroglia.
Titled “Neurology” - functioning and disorders of nervous system.
Neurons have a soma (or cell body) and processes, which are extensions from the soma that receive or carry information. Processes can be diversified as dendrites which receive information or axon which carries information. The axon shown here is covered by insulating sheaths of myelin.

#deepdream code informatique de l'intelligence artificielle de Google spécifique "Fractal DDC " développé et dédié pour un nouvel art à La Demeure du Chaos - The Abode of Chaos ou comment les machines perçoivent La Demeure du Chaos - The Abode of Chaos
et si leurs regards étaient ce qui se cache derrière la matrice que nous percevons en tant qu'humains? ces multiples miroirs sont peut-être un autre monde plus réel ou plus éthéré... NB thierry bonne lecture de ce post et ses images dantesques.
Depuis quelques temps vous avez peut-être vu circuler sur les réseaux sociaux des images étranges, affublées d'un hashtag (mot-clé) #deepdream.
Deep Dream est un programme d'intelligence artificielle mis au point par les ingénieurs de Google. Ces derniers travaillent à la reconnaissance d'images pour, entre autres, améliorer la pertinence des recherches dans Google. Le 17 juin dernier ils ont publié un billet intitulé : "Inceptionnisme : plus loin dans les réseaux neuronaux".
Dans ce post ils expliquent comment ils ont réussi, dans leurs recherches, à faire analyser une image mais surtout générer des formes par l'ordinateur. Pour que l'intelligence artificielle puisse mieux reconnaître ce qui compose une image, les ingénieurs ont commencé par lui montrer des millions de photos.
Plusieurs couches de neurones
L'intelligence artificielle fonctionne ici en un ensemble de réseaux de neurones qu'il faut se figurer comme différentes couches. La première est chargée de regarder les bords et les angles d'une image.
Les couches intermédiaires cherchent quant à elles les formes et les différents éléments présents dans l'image comme une feuille ou une porte. Les derniers réseaux assemblent toutes ces informations pour en fournir des interprétations complexes, comme des arbres ou des bâtiments.
Pour comprendre au mieux comment fonctionnent ces couches, les ingénieurs ont tenté de pousser l'analyse de certaines. Ils résument ainsi la commande faite au système : "Quoi que tu vois, on veut le voir encore plus." C'est alors que l'intelligence artificielle a généré des formes au sein des clichés.
"Si un nuage ressemble un petit peu à un oiseau, alors le système va le faire ressembler encore plus à un oiseau, expliquent les ingénieurs. En réitérant l’action, le programme va reconnaître un oiseau plus fortement et ainsi de suite jusqu’à ce qu’un oiseau très détaillé apparaisse, comme sorti de nulle part."
"L'inceptionnisme"
Les images varient selon le réseau neuronal qui est amplifié. Par exemple, plus on sollicite les couches inférieures, plus des traits vont apparaître. Si on stimule d'avantage les couches supérieures, ce sont des objets qui émergent de l'image.
Les ingénieurs précisent d'ailleurs que comme l'ordinateur a enregistré beaucoup de clichés d'animaux durant son entraînement, il en reproduit souvent. Et parfois en les mixant, ce qui crée des créatures étranges.
Pour ces chercheurs, le Deep Dream a ainsi créé un mouvement artistique qu'ils appellent "l'#inceptionnisme", en référence à l'architecture des réseaux neuronaux.
Au début, cette expérimentation ne cherchait qu'à améliorer l'intelligence artificielle. Mais lorsque les ingénieurs ont posté ce billet, de nombreux internautes se sont intéressés à ce Deep Dream.
Google a donc rendu public le code utilisé pour générer ces images. Des informaticiens s'en sont emparés et ont mis au point des logiciels et des interfaces pour que les internautes puissent s'en servir.
Ce qui ne manque pas de plaire à Google. Les chercheurs encouragent à taguer les images #deepdream sur Twitter, Facebook ou Google+. "Il sera intéressant de voir quelles images les gens arrivent à générer", écrivent-ils.
Environmental biology students gather samples from the DuPage River to test water conditions and quality a few weeks after 7 inches of rain caused extensive flooding in the Naperville area.
When I first saw these odd branched cracks in the ice, I thought of dendrites, but apparently my high school science is too far in the past -- my son informed me it was neurons I was thinking of, dendrites are only part of the neuron . . .

A cultured hippocampal neuron is stained for the neuronal marker MAP2 (green) and F-actin (red), which preferentially labels dendritic spines. Liu et al. reveal that the cytoplasmic C-terminal domain of Neuroligin 1 promotes synapse formation by binding to spine-associated Rap GTPase-activating protein (SPAR) to induce LIMK1/cofilin-mediated actin reorganization.

The axon from a central sympathetic neuron in the spinal cord can project to the periphery in a number of different ways. (a) represents the spinal nerve pathway where the preganglionic fiber projects out and synapses onto a ganglionic neuron at the same level which then carries the information out through the spinal nerve. (b) represents the postganglionic sympathetic nerve pathway where a preganglionic branch projects and synapses onto a more superior or inferior ganglion in the chain which then carries the information out through a symapthetic nerve. (c) represents the splanchnic nerve pathway where a preganglionic branch extends through the white ramus communicans, but does not terminate on a ganglionic neuron in the chain. Instead, it projects through one of the splanchnic nerves to a prevertebral (collateral) ganglion.

Steven Strogatz has a way of finding rhythm in places most people overlook. In his office at Malott Hall at Cornell, and later in the Space Sciences Building at the SPIF, that rhythm came alive in a simple but elegant experiment. Two small metronomes ticked on a shared platform, gradually aligning their beats as if discovering a shared pulse. Strogatz leaned in, smiling as the synchronization unfolded. The moment captured both his joy and his curiosity, the twin forces that have guided his life in mathematics.
For decades, Strogatz has explored the hidden order beneath the world’s apparent chaos. His work has spanned from the synchrony of fireflies flashing in unison to the oscillations of the human heart. He has revealed how patterns emerge naturally when systems, whether biological, physical, or social, interact in just the right way. His research on coupled oscillators, complex networks, and nonlinear dynamics has reshaped how scientists think about everything from brain function to the spread of ideas.
At Cornell, Strogatz is known as a gifted communicator who bridges the gap between advanced mathematics and everyday experience. His lectures attract students from across the university. In books such as Sync, The Joy of x, and Infinite Powers, he writes with clarity and wonder, turning abstract ideas into stories that feel alive. His voice carries the same enthusiasm whether he is explaining calculus or describing the geometry of friendship.
What sets him apart is not only his command of mathematics but his warmth and wit. He listens as carefully as he speaks, often finding metaphors in the natural world or in a casual conversation with a colleague. His humor disarms. His curiosity invites. Watching him adjust the metronomes, eyes bright behind his glasses, it is easy to understand why students and collaborators describe him as both rigorous and kind.
Beneath it all is a belief that mathematics is not separate from life but a language that reveals its beauty. The dance of the metronomes, the firing of neurons, the movement of planets, and the laughter shared across a classroom all express a single truth about connection and harmony.
In person, Strogatz radiates calm delight in the act of discovery. The photograph from that afternoon shows him resting on his arms, thoughtful, as the metronomes begin to fall into sync before him. It is a quiet moment that suggests something larger, a glimpse of the universal tendency toward order and the human impulse to understand it.

Detail of a painting by Doc Wight, in the lobby of the Atlas Building, 406 Collins Street Melbourne CBD.
Doc took to painting in his retirement. And was 'discovered' by the noted art dealer, Richard Llewellyn, in Adelaide.
"His recent works involve bypassing the conscious and working with subconscious motives. He likes to play with colour and non-personal mark-making," I quote from a description of the three paintings at 406 Collins Street.
Doc lives in Melbourne. His studio is in Hawthorn.
The images represent confocal reconstructions of hippocampal neurons grown on 3D-Scaffold.
The cultures were first immunolabelled for β-tubulin III (in red) in order to visualize the neurons; Glial Fibrillary Acidic Protein (GFAP, in green) to visualize glial cells and DAPI (in blue) for nuclei. The images were acquired using a sophisticated Laser-Scanning Confocal Microscope for viewing samples in 3D, which is not possible in standard microscopes.
The 3D renderings demonstrate that the cells grown on such substrates are capable of migrating and forming connections in all spatial configurations, thus overcoming the constraints imposed by culturing on flat surfaces. The reconstructions are of neurons and glial cells spreading through a thickness of 60-100 micron (consider that the size of neuronal soma is around 10 micron). Using this highly technological approach we were able to appreciate that the cells and their processes were not simply anchored to the scaffold but were in fact navigating the pores present in the 3D-structure.

Rosehips are very similar to neurons - brain cells. Like neurons, they have a variety of shapes, they age and die. And how well we preserve our neurons (as well as plants) depends on us. Neurons in our brain, like the rosehips in our gardens, are in our hands.
This picture, taken on February 26, is of an archer fish in my friend's aquarium. The Archer Fish (Toxotes jaculatrix), sometimes called the Banded Archer Fish is a brackish water fish found often in small riviers and streams in Asia. Archer Fish are known for their ability to spit at their prey, with extreme accuracy. For a while, this behavior was a mystery to ichthyologists and other scientists, and only recently have studies found out what actually allows the archer fish to spit with great force and accuracy. Their spit is shot like a water jet, knocking insects and other prey into the water to be consumed. Based on research from a study by a physicist in Italy, it has been found that if this stream of water were to hit a human in the face, it would cause pain similar to that of an insect bite or sting. It was found that the spit stream must be shot with a single burst, done by continuously changing the shape of their mouths. The speed and size of the spit both increase as it reaches its prey, maximizing momentum. The Archer Fish can shoot up to two meters out of the water, giving them a relatively large range to capture prey. Scientists believe that these are among the most intelligent of fish, and their hunting behavior is controlled by neurons which may also play a role in social learning among the species.

We've begun annotating the pharynx nervous system of the nematode Pristionchus pacificus as part of our effort to produce a wiring diagram showing all of the synaptic connections in the nervous system. This image is a 3D reconstruction showing parts of two neurons (yellow and green) as well as a large number of synapses (blue) that are associated with the yellow neuron. Already we see big differences between our nematode and the model organism Caenorhabditis elegans.
Duke Professor Henry Greenside's research in neuroscience is informed by his approach as a physicist.
Greenside writes, "Mitya's statistical theory of neuronal shape explains several details of why pyramidal cells and Purkinje cells have the shapes they do, e.g., why pyramidal cells are spread out and sparse while Purkinje cells are flat and dense.
This animated figure illustrates the 3d structure of a pyramidal neuron. All of
my attention has been focused on the lower red "basal dendritic tree", which is the easiest part of the neuron to compare with Mitya's theory."
In Naked Knotted Neurons, a group of protesters, some injured, some choking on tear gas, escape violent confrontation with police and other forces by staggering into a safe house they find in the midst of chaos. Strangers to one another, they soon discover they are from different worlds: all were involved in protests, but in different places and times. A trio of dieties, Fate, Chance and Destiny, have gathered them together to charge them with a task: to create a new Hero to solve the world’s most intractable, knotted problems. How to get this message across? Puppets, riddles, and audience participation reveal the secrets the protesters need to fulfill this task.
Following their run at the International Fringe Festival in Edinburgh, Scotland, the Penn Theatre Ensemble presented the company-devised piece Naked Knotted Neurons at Annenberg Center Live on September 4th and 5th, 2015.

"Neuron" by American artist Roxy Paine.
The colossal stainless steel structure stands at 41 feet in the Cultural Commons, an expansive meadow enclosed by trees. Installation occurred in mid-April and the site is now officially open to the public.
"It is an honor to be a part of this amazing collection and beautiful sculpture park," said the artist.
"Neuron," part of Paine's "Dendroid" series, is an abstract, re-imagined tree hand-constructed of approximately 3,500 stainless steel rods and cylindrical industrial piping commonly used in pharmaceutical and nuclear power plants.
Paine's juxtaposition of nature and industry is central to his acclaim as one of the most important sculptors of his generation.
"I strive for imagery that is between things nature and industry, science and art, but not quite comfortable in either world," said Paine.
Among the twenty globally sited Dendroid siblings, "Neuron" is unique. While most of the others more closely resemble trees, this one is the least literal and the most visually complex.
"Arguably, "Neuron" is the most compelling to date as a powerful abstract form that breaks freely from traditional representational imagery," said Joseph Becherer, Vice President and Chief Curator of Sculpture at Frederik Meijer Gardens & Sculpture Park.
"On one hand, it is not immediately linked to a natural form, nor is it directly connected to anything industrial, although it is something of both," said Becherer. "More than a complete enigma, it does suggest excitability and energy of its biological namesake. In one breath, such a sizeable and powerful - www.artdaily.org/index.asp?int_sec=11&int_new=47688
