brain

The control center of the central nervous system of an animal located in the skull which is responsible for perception, cognition, attention, memory, emotion, and action.

How to use

In everyday conversation, the word 'brain' is often used to refer to the human brain, but it can also be used to describe the central nervous system of other animals, such as insects or fish. For example, 'The octopus has a highly developed brain that allows it to solve complex problems.' However, it's worth noting that in formal or technical contexts, the word 'encephalon' is often used to refer to the brain in a more precise and scientific manner. This can be a common pitfall for non-native speakers, who may not be familiar with the nuances of English vocabulary.
