This group exhibition, including work by Catherine Richards, Michael Snow, Scott Rogers, Thomson & Craighead and Simon Pope, draws on ideas of scientific experimentation, media processing, and time delay. Each work acts to slow down our senses of perception, causing within us an awareness of both time passing and our experience of it. The title refers to that fact that we often watch other people interact with responsive art, and mirror their behaviour, consciously or not.
Catherine Richards’ I was scared to death / I could have died of joy features glass replicas of the brain, which react to your presence with pulses of electromagnetic light. Scott Rogers’ Between Nonesuch Place juxtaposes an actual non-functioning glass object, a ‘self-flowing flask’ with its virtual working counterpart. Thomson & Craighead’s Flipped Clock is a modified digital clock display, where each individual digit is rotated by 180-degrees. Simon Pope’s Recall From Memory the Space of Another Gallery is an invitation for the visitor to recall experiences of being in other gallery spaces from memory. The seminal filmmaker Michael Snow’s WVLNT: Wavelength for those who don't have the time. Originally 45 minutes, Now 15! remixes his own seminal work Wavelength.

Coupe parasagittale au niveau des replis de la valvule du cervelet. La technique de coloration est la même que celle de la figure P11a_010 avec un grossissement des replis multiplié par quatre. Cette méthode à l’argent, utilisée sur coupes à la paraffine, est rapide et assez bien reproductible. Elle teinte en noir le réseau neurofibrillaire des dendrites et axones mais pas les corps cellulaires, qui présentent une teinte brun-orangé.

Parasagittal section through the folds of the valvula cerebelli. Neuronal processes can be quite easily
demonstrated in paraffin sections by using the silver
impregnation according to Tinel. This rapid and
fairly reliable method stains axons, fibrillary structures
(neurofibrils) and dendrites of many neurons in
black, with some differences depending on the procedure.
Cell bodies (somata) of neurons are in shades of orange brown.

Growing brain cells from humans to understand brain development and disease has become possible with the advent of induced pluripotent stem cell (iPSC) technology. Here, a skin biopsy is taken and the resulting skin cells grown in a dish. These cells are then reprogrammed to naive stem cells using a clever cocktail of biological factors. These stem cells are now pluripotent - meaning they can be differentiated into any cell type in the body with the appropriate instructions. In this image, human iPSCs have been instructed to make cortical brain cells, or neurons, which make up three quarters of the human brain. The red flower-like structures, known as ‘rosettes’, are labelled for a marker of neuronal stem cells. These neuronal stem cells give rise to the more mature neurons, labelled green, with their characteristic long branches. The nuclei of these cells are labelled blue. A truly remarkable process.
By activating multiple fluorescent proteins in neurons, neuroscientists at Harvard University are imaging the brain and nervous system as never before, rendering their cells in a riotous spray of colors dubbed a "Brainbow";
Brainbow allows researchers to tag neurons with roughly 90 distinct colors, a huge leap over the mere handful of shades possible with current fluorescent labeling. By permitting visual resolution of individual brightly colored neurons, this increase should greatly help scientists in charting the circuitry of the brain and nervous system.

1998 frame built with Columbus Neuron, fully chromed, lovely lugwork. Unfortunately paint is in very poor condition, lots of rust spots on the chainstays and inside the fork crown and legs. Awaiting full restoration including new chrome and wet paint. Will be dressed in mid 90's Campagnolo Chorus.

Onkologie
Was hier wie ein Halsreif aussieht, entpuppt sich im Blick der Wissenschaft als die Schleife, durch die es den Zellausläufern gelingt, zu dem grünen Wachstumskegel zurückzukehren, dem sie entwachsen sind. Lange Ausläufer dieser Art bringen nur Nervenzellen zustande, und sie verlieren diese Fähigkeit nicht, wenn sie aus der natürlichen Umgebung genommen und in die Kulturschale gebracht werden. Gelungen ist die Aufnahme mit einem Fluoreszenzmikroskop, mit dessen Hilfe die Wissenschaftler vor allem nach Faktoren suchen, die das Wachsen entarten und gefährlich werden lassen.

A Neuron in the Spotlight
Every neuron in an artificial neural network can be seen as a mathematical function which, as a rule, connects several inputs to an output. From the input values, the neuron generates an output value that is passed on to the next layer of neurons. The higher this value is, the more “active” the neuron becomes in the network. This is why we refer to so-called activation functions. At this station you can try out how different mathematical functions in the neuron affect the output.

a close up (width of photo = roughly .0001m) of young neurons born recently in the adult mouse brain. the blue is NeuN, a protein found only in neurons (and is therefore good for identifying them) and the red/pink is doublecortin, a protein found only in young neurons. doublecortin is needed for neuronal processes to be able to grow and contact other neurons. when the neurons mature and have formed all their connections they no longer need doublecortin. you can see that all the neurons but those at the left-most edge are therefore mature.

…neuroni alla ricerca di una strada mai percorsa, / labirinti cerebrali specchiati, / tutto è come amplificato, bizzarro, / sono un proiettile impazzito nella fantasia cosmica….

Encéphale. Les péricaryons des neurones moteurs de l’encéphale contenant les corps de Nissl
(flèches bleues) donnent à ces cellules un aspect moucheté. Les corps de Nissl sont des amas de réticulum endoplasmique granuleux. Les cercles entourent diverses cellules gliales (astrocytes, oligodendrocytes, microgliocytes)
non reconnaissables avec la méthode de coloration utilisée. Le noyau (X) des neurones est imposant, ovoide et plus ou moins en position centrale.

Encephalon. Motor neurons containing NISSL bodies
(blue arrows) give the neuronal cytoplasm a granular
appearance. NISSL bodies are large granules which
consist of rough endoplasmic reticulum (i.e. with ribosomes).
The circles show various glial cells (astrocytes,
oligodendrocytes or microglial cells) not distinguishable
with the trichrome stain. The nucleus (X) of the neuron is large, ovoid and centrally located in the cytoplasm.
