Hybrid practices are emerging that integrate creative materials like paint, clay, and cloth with intangible immaterials like computation, electricity, and heat. This work aims to expand the design potential of immaterial elements by transforming them into manipulatable, observable and intuitive materials.

Where Are the fMRI Correlates of Phosphene Perception?
Pulses of transcranial magnetic stimulation (TMS) over occipital cortex can induce transient visual percepts called phosphenes. Phosphenes are an interesting stimulus for the study of the human visual system, constituting conscious percepts without ...

Background: Visual cortical prostheses (VCPs) have the potential to restore visual function to patients with acquired blindness. Successful implementation of VCPs requires the ability to reliably map the location of the phosphene produced by stimulation ...

Use of cortical electrodes in solving visual prosthesis problems
There are two main approaches to visual function prosthesis in blindpatients with the use of brain-computer interfaces on the basisof either retinal or cortical stimulation by implanted electrodes. Themost complex in visual prosthesis is creation of the

Mapping the visual brain areas susceptible to phosphene induction through brain stimulation. [PDF]
Transcranial magnetic stimulation (TMS) is a non-invasive brain stimulation technique whose effects on neural activity can be uncertain. Within the visual cortex, phosphenes are a useful marker of TMS: They indicate the induction of neural activation ...

Simulation of thalamic prosthetic vision: reading accuracy, speed, and acuity in sighted humans [PDF]
The psychophysics of reading with artificial sight has received increasing attention as visual prostheses are becoming a real possibility to restore useful function to the blind through the coarse, pseudo-pixelized vision they generate.

Phosphene phenomenon: A new concept [PDF]
This paper proposes a new biopsychophysical concept of phosphene phenomenon. Namely, visual sensation of phosphenes is due to the intrinsic perception of ultraweak bioluminescent photon emission of cells in the visual system. In other words, phosphenes are bioluminescent biophotons in the visual system induced by various stimuli (mechanical, electrical,

Background: High-channel-count neuroprostheses could one day restore functional vision in blind individuals by delivering electrical pulses to electrodes in the visual cortex that elicit perceptions known as ‘phosphenes’.
