Coming up this Sat., March 28th at Thinkspace in our project room:

Erik Jones ( @erikjonesart )
‘Color|Full’

Jones’ technically complex mixed-media works combine the figurative with the geometric in seamless collusion and concert. Jones’ hyperrealistic figuration is offset by geometric patterns and momentums that seem to live and breathe as symbiotic organisms. The figure is ensconced by these colorful geometric expanses, as each “wears” the other and becomes virtually indivisible from its counterpart. Clothed by pattern and color, the body is set within and against expressionistic modules of sculpted graphic space. In his new body of work, Jones takes his penchant for spatial play and surreal composition to the next level in a series of Dimensional Paintings. These works invade the third dimension, literally, as surfaces peel from their supports, images slide from the walls, and paint pools on the floor.

Jones will be in town for the opening as well from NYC.

An Inquiry

What is a thought? What is it made out of? Where is it beginning and ending? Can you rethink the thought you just thought? Can the mind be found? Or is it just a thought? Can a thought, in truth, be found? Has a thought ever came into existence? Or is it just another word for infinite empty space? If something truly existed separately, would it require naming? What is unaffected by names? How did the sky make you feel as a child? What does the heart know that the mind doesn’t? What requires absolutely no effort, no sustaining, no time, no cognition, no process, no location or basis? What isn’t orientated in any direction? Why is something beautiful? What is the mind always too late for? What in you assumes nothing? Onto what does the mind superimpose spatial dimensions? What is pure and untouched within you? What is infinitely unfathomably transparent? What is beyond all possible obscuration? What in you is completely free and open to life? …….

Mapping blank spots in the cheeseboard maze

IST Austria Professor Jozsef Csicsvari together with collaborators succeeds in uncovering processes in which the formation of spatial memory is manifested in a map representation • Researchers investigate timescale of map formation • Inhibitory interneurons possibly involved in selection of map

During learning, novel information is transformed into memory through the processing and encoding of information in neural circuits. In a recent publication in Neuron, IST Austria Professor Jozsef Csicsvari, together with his collaborator David Dupret at the University of Oxford, and Joseph O’Neill, postdoc in Csicsvari’s group, uncovered a novel role for inhibitory interneurons in the rat hippocampus during the formation of spatial memory.

During spatial learning, space is represented in the hippocampus through plastic changes in the connections between neurons. Jozsef Csicsvari and his collaborators investigate spatial learning in rats using the cheeseboard maze apparatus. This apparatus contains many holes, some of which are selected to hide food in order to test spatial memory. During learning trials, animals learn where the rewards are located, and after a period sleep, the researchers test whether the animal can recall these reward locations. In previous work, they and others have shown that memory of space is encoded in the hippocampus through changes in the firing of excitatory pyramidal cells, the so-called “place cells”. A place cell fires when the animal arrives at a particular location. Normally, place cells always fire at the same place in an environment; however, during spatial learning the place of their firing can change to encode where the reward is found, forming memory maps.

In their new publication, the researchers investigated the timescale of map formation, showing that during spatial learning, pyramidal neuron maps representing previous and new reward locations “flicker”, with both firing patterns occurring. At first, old maps and new maps fluctuate, as the animal is unsure whether the location change is transient or long-lasting. At a later stage, the new map and so the relevant new information dominates.

The scientists also investigated the contribution of inhibitory interneuron circuits to learning. They show that these interneurons, which are extensively interconnected with pyramidal cells, change their firing rates during map formation and flickering: some interneurons fire more often when the new pyramidal map fires, while others fire less often with the new map. These changes in interneuron firing were only observed during learning, not during sleep or recall. The scientists also show that the changes in firing rate are due to map-specific changes in the connections between pyramidal cells and interneurons. When a pyramidal cell is part of a new map, the strengthening of a connection with an interneuron causes an increase in the firing of this interneuron. Conversely, when a pyramidal cell is not part of a new map, the weakening of the connection with the interneuron causes a decrease in interneuron firing rate. Both, the increase and the decrease in firing rate can be beneficial for learning, allowing the regulation of plasticity between pyramidal cells and controlling the timing in their firing.

The new research therefore shows that not only excitatory neurons modify their behaviour and exhibit plastic connection changes during learning, but also the inhibitory interneuron circuits. The researchers suggest that inhibitory interneurons could be involved in map selection – helping one map dominate and take over during learning, so that the relevant information is encoded.

Bojana Danilovic has what you might call a unique worldview. Due to a rare condition, she sees everything upside down, all the time. The 28-year-old Serbian council employee uses an upside down monitor at work and relaxes at home in front of an upside down television stacked on top of the normal one that the rest of her family watches.

Experts from Harvard University and the Massachusetts Institute of Technology have been consulted after local doctors were flummoxed by the extremely unusual condition. According to them, she is suffering from a neurological syndrome called "spatial orientation phenomenon."  (Source)

SpaceTop

A transparent 3D spatial desktop display prototype by Jinha Lee, first public in February 2013 (can’t believe I missed this …) - video embedded below:

SpaceTop is a technological and design solution to fuse 2D and spatial 3D interactions in a single desktop workspace. It extends the traditional desktop interface with interaction technology and visualization techniques that enable seamless transitions between 2D and 3D manipulations. SpaceTop allows users to type, click, draw in 2D, and directly manipulate interface elements that float in the 3D space above the keyboard. It makes it possible to easily switch from one modality to another, or to simultaneously use two modalities with different hands. We introduce hardware and software configurations for co-locating these various interaction modalities in a unified workspace using depth cameras and a transparent display. We describe new interaction and visualization techniques that allow users to interact with 2D elements floating in 3D space and present the results from a preliminary user study that indicates the benefit of such hybrid workspaces.
