What we're talking about here is electrotactile stimulation for sensory augmentation or substitution, an area of study that involves using encoded electric current to represent sensory information -- information that a person cannot receive through the traditional channel -- and applying that current to the skin, which sends the information to the brain. The brain then learns to interpret that sensory information as if it were being sent through the traditional channel for such data. In the 1960s and '70s, this process was the subject of ground-breaking research in sensory substitution at the Smith-Kettlewell Institute led by Paul Bach-y-Rita, MD, Professor of Orthopedics and Rehabilitation and Biomedical Engineering at the University of Wisconsin, Madison. Now it's the basis for Wicab's BrainPort technology (Dr. Bach-y-Rita is also Chief Scientist and Chairman of the Board of Wicab). Eyeglasses are a typical example of sensory augmentation. Braille is a typical example of sensory substitution -- in this case, you're using one sense, touch, to take in information normally intended for another sense, vision. “There is no purgatory for war criminals,” Kyslytsya said to the Russian ambassador at the end of the meeting. ”They go straight to hell”. Ukrainian Ambassador to the U.N. These developments came after Russian President Vladimir Putin announced that Russia was launching a “special military operation” against Ukraine, effectively declaring war. There were subsequently reports of explosions in multiple Ukrainian cities, including the capital city of Kyiv. “President Putin has chosen a premeditated war that will bring a catastrophic loss of life and human suffering. Russia alone is responsible for the death and destruction this attack will bring, and the United States and its Allies and partners will respond in a united and decisive way,” Biden said in a statement. Biden has repeatedly said that the US will not send in troops to defend Ukraine against a Russian attack, but earlier this week, he slapped sanctions on Russia over its recent actions. The president has also warned of “steeper” consequences if Russia escalated the situation and continued take aggressive steps against Ukraine. To join the conversation, please log in.
