The ScienceDaily article Leveraging Learning For Artificial Respiration said
MIT researchers have found that the body’s innate ability to adapt to recurring stimuli could be leveraged to design more effective and less costly artificial respirators. The new approach could minimize the need for the induced sedation or paralysis currently necessary for some patients on mechanical ventilation.
Nonassociative learning, or our innate ability to adapt to recurring stimuli, is the focus of work to be described in PLoS One, Public Library of Science journal.
Specifically, Chi-Sang Poon, a research scientist at the Harvard-MIT Division of Health Sciences and Technology (HST), and colleagues examined rats under mechanical ventilation to see how they applied different forms of nonassociative learning to adapt to the rhythm imposed by the respirator.
