Rat hippocampal neuron-glial cultures co-infected with VSV-G pseudotyped lentiviral vectors expressing reporter gene GFP (green) and V5 Tagged tau proteins (red) especially in the population of astrocytes. Cells were imaged by acquisition of multiple optical sections with a Zeiss LSM 710 Quasar confocal system (Cellular Imaging Facility of UNIL - Lausanne) with a 40X objective and digital zoom set to four. This picture exhibited astrocytic network complexity and how tau proteins is differentially located and expressed in astrocytic neuronal compartments. Tau is an essential element for our human brain. As a ligament for bones, tau participates to structure and flexibility of brain neurons. However, during normal or ages-related diseases (Alzheimer diseases or dementia) tau changes and consequently the neuronal structure also. We can understand the complexities of neuronal network with culture of cells infected with viral vector expressing fluorescence markers (green and red)

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.

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.
The marsh was completely frozen. Now it is starting to thaw in places and these wonderful ice neurons abound.

Animated Neuronal transmission : It is one of the most important function of the body. What we call our senses are impulses travelling from various parts of the body to brain. Unknow to us however there are billions of connections made to transfer info from internal organs to the brain. It is the intricate neuron cellular network that keeps our body alive. This neuronal transmission animation gives in-depth information about how our nervous system functions.

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.

Es mag unglaublich klingen, aber die engen, feinen Verästelungen auf diesem Bild gehören nur zu einer einzigen Nervenzelle. Aus einem deutlich erkennbaren Zellkörper im Zentrum streckt das Neuron seine Fühler in die Umgebung aus - in alle Richtungen und auf allen Wegen.
