Emotional intelligence is associated with connectivity within and between resting state networks

Area of Science:

• Neuroscience
• Cognitive Science
• Psychology

Background:

• Emotional intelligence (EI) is crucial for mental health and success.
• The neural basis of EI, particularly its link to intrinsic brain function, is not well understood.
• Previous research has not examined the relationship between EI and resting-state brain networks.

Purpose of the Study:

• To investigate the association between emotional intelligence and intrinsic neural network function.
• To explore how resting-state functional connectivity relates to both ability-based and trait-based EI.
• To identify specific brain circuits involved in EI.

Main Methods:

• Functional magnetic resonance imaging (fMRI) was used to collect resting-state data from 54 healthy adults.
• Independent components analysis (ICA) with dual regression was applied to analyze intrinsic brain networks.
• Self-reported (Trait EI) and objectively measured (Ability EI) emotional intelligence were assessed.

Main Results:

• Higher Ability EI was associated with stronger negative functional connectivity between the basal ganglia/limbic network (BGN) and the posterior default mode network (DMN).
• This association extended to regions involved in emotional processing and regulation.
• Trait EI did not show a significant association with the observed functional connectivity patterns.

Conclusions:

• Intrinsic brain network function, particularly the interplay between networks involved in mentation and emotion regulation, is strongly linked to ability EI.
• These findings highlight the neural underpinnings of objectively measured emotional intelligence.
• The study provides novel insights into the neurocircuitry supporting emotional intelligence.
