Neural Representation of Exogenous and Endogenous Temporal Expectations Based on fMRI

Key Points

This research aims to understand how the brain represents exogenous and endogenous temporal expectations during cognitive tasks.
Utilized fMRI to examine brain activity under conditions of temporal expectations.
Compared neural activation patterns related to exogenous and endogenous expectations against resting-state networks.
Cerebral regions for exogenous and endogenous expectations showed similar activation compared to resting-state networks.
Proposes two cognitive modes in the cerebrum based on different temporal expectations.

Abstract

We found that the sum of exogenous and endogenous temporal expectations related cerebral regions was almost the same when compared to resting-state networks (RSNs). We propose that the cerebrum could activate in two modes for cognition: one is based on endogenous temporal expectations, and another is based on exogenous temporal expectations.
