The 28-year-old man, who has been paralysed for more than a decade after a spinal-cord injury, had electrodes from the prosthetic hand inserted into his sensory and motor cortexes. This allowed him to both control the hand with thought and sense when the fingers of the hand were touched individually.
Dinitrogen monoxide is its IUPAC name and its common name is laughing gas. Its chemical name is nitrous oxide itself.
The gas is a mixture of half nitrous oxide (N 2 O or laughing gas) and half oxygen (O 2). The ability to combine N 2 O (nitrous oxide is the common name; dinitrogen monoxide, systematic name) and oxygen at high pressure while remaining in the gaseous form is caused by the Poynting effect (after John Henry Poynting, an English physicist).
