Distinctive brain pattern helps habits form

Neuroscientists have found that certain neurons in the brain are responsible for grouping behaviors together into a single habitual routine, in a process known as 'chunking.' These neurons, located in a brain region highly involved in habit formation, fire at the beginning and the end of a habitual behavior, but not in the middle. https://www.sciencedaily.com/releases/2018/02/180208120923.htm
