What is "chronesthesia"

Chronesthesia, or mental time travel, is a mental ability first hypothesized by Endel Tulving in the 1980s. This refers to the ability to be aware of one's past or future. While many may describe it as uniquely human, others now argue that this ability can transcend to include non-human animals such as birds. The mechanisms of mental time travel are not yet fully understood since there is a level of obscurity and complexity when trying to measure if or when someone underwent mental time travel or not. However, studies have been conducted to map out areas of the brain that may be responsible for mental time travel.
