Meditation Matters A study by Sara Lazar and her colleagues (2005) found that cortical areas shown in red and yellow were significantly thicker in meditators than in a matched control group. The somatosensory cortex and insula are both associated with sensory awareness, with the insula specifically linked to awareness of internal body sensations and signals. According to the researchers, the particular region of the prefrontal cortex that was thicker in the meditators than the controls is thought to be associated with the integration of thoughts and feelings.
