the truth of images

"I paint missing links, reflections on neurological processes."
1. What is an image?
image is a reference to some aspect of the world which contains
within its own structure and in terms of its own structure
a reference to the act of cognition which generated it. It
must say, not that the world is like this, but that it was
recognized to have been like this by the image-maker, who leaves
behind this record: not of the world, but of the act. An image
is formed in the mind by patterns of neural activity. Visual
consciousness is not a single unified entity, but consists
of many microconsciousnesses.
2. When and where is an image?
results from three distinct and successive processes: optical,
chemical and nervous. White
matter consists of bundles of neuronal axons that form connections
between neurons, allowing brain regions to communicate with each
matter, or cortex, is where the bodies of neurons are located. You
see (perceive) what you are.
3. How does an image takes form?
brain processes information in a specific order, and this serial
processing is hierarchial. Perception can be defined as attaching
significance to visual information. The cognitive work of images;
colour, form, and movement are not perceived simultaneously.
Visual information regarding form, movement, colour and depth
are each processed by a different group of neurons in the brain,
for example colour is perceived before orientation, which is
perceived before motion. An image takes form by sequential
neural actions. Neurological processes are based on the fact that the
brain and the body can't lie.
The mind is what the brain does. We are neural beings. Neuroscience will give rise to a new type of human
society, a post-industrial, post-informational, neurosociety. (1) (2)
can be provisionally defined as the critical meliorative study
experience and use of one's body as a locus of sensory-aesthetic
(aesthesis) and creative self-fashioning.
team of Yukiyasu Kamitani (ATR Computational Neuroscience Laboratories
in Kyoto, Japan) has used an image of brain activity taken
in a functional MRI scanner to recreate a black-and-white image from scratch. "By
analysing the brain signals when someone is seeing an image,
we can reconstruct that image," says Kamitani.
The next step is to find out if it is possible to image things
that people are thinking of, as well as what they are looking
at. It may be possible to "make
a videotape of a dream" says John-Dylan Haynes
of the Max Planck Institute for Human Cognitive and Brain
Sciences in Leipzig, Germany.
