This study presents phosphenotron, a device for enhancing the sensory spatial resolution of phosphenes in the visual field (VF). The phosphenotron employs a non-invasive transcranial alternating current stimulation (NITACS) to modulate brain activity by applying weak electrical currents to the scalp or face. NITACS's unique application induces phosphenes, a phenomenon where light is perceived without external stimuli.

- Calluses are thickened skin areas formed due to friction or irritation, typically harmless but can lead to infections if untreated.
- The article explores the effectiveness of thermal imaging in assessing calluses, showing that temperature drops in the skin can indicate the presence of calluses.
- Experimental validation supports the idea that a temperature decrease of 0.5°C or more can signal callus presence, emphasizing the need to consider ambient temperature during assessments.
This study focused on the use of Non-Invasive Transcranial Alternating Current Stimulation (NITACS) to induce and map phosphenes (spark-like percepts in the visual field) in healthy individuals. The study found optimal stimulation parameters to induce reliable phosphenes without skin irritation or pain. The results suggest NITACS can be used as a tool to investigate the relationship between facial stimulation location and phosphene localization within the field of vision (FOV) and raise questions about the origin of phosphenes generated through NITACS.
