[Mental Space Navigation and Mental Time Travel].

Area of Science:

• Neuropsychology
• Cognitive Neuroscience

Background:

• Mental time travel, the ability to mentally project oneself into the past or future, is a complex cognitive function.
• Disorders affecting mental space navigation and mental time travel present unique challenges in clinical neuropsychology.

Purpose of the Study:

• To identify specific brain regions critical for the cognitive process of mental time travel.
• To understand the neuroanatomical underpinnings of mental time travel disorders.

Main Methods:

• Examination of patients diagnosed with mental space navigation or mental time travel disorder.
• Neuropsychological assessment to identify affected brain regions.

Main Results:

• Key brain regions implicated in mental time travel include the precuneus, posterior cingulate gyrus, retrosplenial cortex, and hippocampus.
• Both anterior and posterior medial areas of the orbitofrontal cortex were found to be important for this process.

Conclusions:

• The identified brain regions (precuneus, cingulate cortex, retrosplenial cortex, hippocampus, orbitofrontal cortex) are crucial for mental time travel.
• Further research is needed to determine if these regions form a cohesive network for mental time travel.
