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.

Frederick “Rusty” Gage has spent his life asking a question many neuroscientists once considered heretical: can the adult brain grow new neurons?
When I photographed him at the Salk Institute in February 2026, that question felt less like rebellion and more like legacy. We made portraits in his study overlooking the Pacific, a quiet room washed in coastal light. The ocean moved below the cliffs in long, steady breaths. It is the same office once occupied by Jonas Salk, who recruited Rusty decades ago. The desk, the view, the gravity of the place. You feel it immediately. History is not abstract there. It presses in from the walls.
In the late twentieth century, neuroscience was built on a stark premise: you are born with a fixed number of neurons. Damage them and they are gone. Memory fades. Injury lingers. Aging narrows possibility. Rusty challenged that dogma with careful, methodical experiments that showed new neurons could, in fact, form in the adult hippocampus. The implications were enormous. Learning, mood, resilience, even the biology of hope took on new dimensions.
In person, what strikes you first is his attentiveness. He leans in slightly when you speak, hands folded, eyes steady behind round glasses. There is warmth in him that feels unforced. Soft spoken, yes, but never distant. You sense a mind that is constantly mapping connections, not only between neurons but between people. Students drift in and out of his orbit with ease. Colleagues seek him out. He listens more than he declares.
The study itself holds layers of meaning. Jonas Salk built the institute as a place where scientists could think expansively, where architecture and intellect met the horizon. Standing in that room with Rusty, you understand that recruitment was more than a hire. It was a passing of trust. Salk had imagined a future for biology that included imagination and risk. Rusty carried that forward into the living brain.
His work has since expanded beyond neurogenesis into how the genome shapes the nervous system over time. His lab explores mosaicism in the brain, the idea that our neurons are not genetically identical but subtly varied. The brain becomes not a static organ but a dynamic landscape, shaped by experience and by the restless choreography of DNA. It is a vision of the self that is fluid and intricate.
Photographing him in that office felt less like documenting a single scientist and more like tracing a lineage. Salk sought a vaccine that would protect children from paralysis. Rusty sought evidence that the adult brain was not condemned to decline. Both projects required a certain stubborn optimism. A belief that the body holds more possibility than we assume.
The weight of history was there, yes. But so was something lighter. A current of curiosity that refuses to settle. In Rusty Gage’s presence, you feel that science is not a monument. It is a conversation, still unfolding, with the ocean as witness.

Les cellules de Purkinje constituent une catégorie spécifique de neurones situés dans le cervelet, dans la couche moyenne duquel elles se répartissent en un alignement très caractéristique de leurs corps (ou somas). La façon dont leurs dendrites (ramifications par lesquelles elles reçoivent l'information provenant des autres neurones) s'arborisent autour de leur corps jusque dans la couche la plus externe du cervelet, est également assez caractéristique et les rend facilement reconnaissables. A l'opposé de cet "arbre dendritique", leur axone (longue ramification unique se terminant par une synapse grâce à laquelle elles transmettent l'information à d'autres neurones) se prolonge en traversant la couche granulaire (couche la plus interne) du cervelet et rejoignent les noyaux cérébelleux profonds où leur synapse se connecte aux neurones de la moelle épinière, du bulbe et du cortex.
Ici, on peut visualiser des cellules de Purkinje marquées par un fluorophore.

#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.
