IPA: /dɪˌsɛrəˈbreɪʃən/
KK: /dɪˌsɛrəˈbreɪʃən/
The process of removing the brain from an organism, often used in medical or scientific contexts.
The experiment involved decerebration to study the effects of brain removal on behavior.
Decerebration is formed from "de-" (meaning down or away) and "cerebrum" (from Latin, meaning brain). The term refers to the process of removing or damaging the brain, effectively taking it away or down from its normal function.
Think of 'taking away' ('de-') the 'brain' ('cerebrum') — that's why decerebration means the removal or loss of brain function.
