“i-consciousness and m-consciousness
Studying consciousness scientifically is difficult when the word has multiple meanings. For clarity, we begin this account by labelling two common categories of meaning for consciousness. The first focuses on information in the brain—how it is selected, enhanced, and processed. The second is a more mysterious, extra, experiential essence that people claim accompanies the informational content. In this account, we will refer to the two as i- consciousness (i for information) and m-consciousness (m for mysterious), although we acknowledge that other researchers may use different terminology.
