Abstract

In a sample of 49 late chronotype young adults, thinner cortical thickness was observed in the left pars orbitalis compared to matched early chronotype individuals.

  • Cortical thickness and other brain structure indicators were examined in relation to chronotype preference.
  • Late chronotype (LC) individuals showed lower cortical mean curve measurements in the right paracentral gyrus.
  • The study emphasizes the relationship between an individual's sleep preference and specific structural brain characteristics.
  • Findings may support the idea that chronotype is linked to variations in brain structure among healthy young adults.
