Human time perspective and its structural associations with voxel-based morphometry and gyrification.

Area of Science:

• Neuroscience
• Psychology
• Brain Imaging

Background:

• Time perspective influences how individuals perceive and evaluate past, present, and future.
• Understanding the neural underpinnings of time perspective is crucial for comprehending behavioral variations and psychopathology.

Purpose of the Study:

• To investigate the relationship between different facets of time perspective, as measured by the Zimbardo Time Perspective Inventory (ZTPI), and structural brain variations.
• To identify specific brain regions associated with distinct temporal orientations in healthy individuals.

Main Methods:

• Voxel-based morphometry (VBM) analysis using the CAT12 software package.
• Analysis of neuroimaging data from 177 psychiatrically healthy subjects.
• Assessment of time perspective using the Zimbardo Time Perspective Inventory (ZTPI).

Main Results:

• Negative past and present fatalistic time perspectives were negatively associated with grey matter volume in the anterior insula.
• A future-oriented time perspective showed a negative association with grey matter volume in the precuneus.
• No significant association was found between ZTPI scores and brain gyrification.

Conclusions:

• Time perspective is linked to structural variations in key brain regions, including the anterior insula (involved in timekeeping) and the precuneus (part of the default mode network).
• These findings suggest a neurobiological basis for the psychological construct of time perspective and its potential relevance to mental health.
