Modulation of Posterior Default Mode Network Activity During Interoceptive Attention and Relation to Mindfulness.

Biological Psychiatry Global Open Science November 1, 2024 Dhakshin Ramanathan, Jason Nan, Gillian Grennan et al. 10 citations

Interoceptive attention to internal sensory signals, such as the breath, is fundamental to mindfulness. However, interoceptive attention can be difficult to study, with many studies relying on subjective and retrospective measures. Response consistency is an established method for evaluating variability of attention on exteroceptive attention tasks, but it has rarely been applied to...

Posterior default mode network activity underlies distracted interoceptive attention and provides an objective basis for low mindfulness & depression

Jyoti Mishra, Dhakshin Ramanathan, Gillian Grennan et al. preprint

Abstract Interoceptive attention to internal sensory signals is fundamental to mindfulness. However, it is difficult to measure objectively, and the vast majority of investigations of the neural correlates of mindfulness-based attention rely on subjective and retrospective measures of distraction. In this study, we measured consistency of response times on a breath-monitoring task (instruction...

Default mode and frontal executive network interactions enable interoceptive attention & mindfulness

Gillian Grennan, Pragathi Balasubramani, Vojislav Maric et al. preprint

Abstract Interoceptive attention to internal sensory signals is fundamental to mindfulness. In an attention-to-breathing task in 161 adults, we found that consistency of interoceptive attention significantly correlated with performance efficiency across several exteroceptive cognitive domain tasks. EEG source mapping within subjects showed that on low-consistency or distracted trials there was...
