GABA in the insula - a predictor of the neural response to interoceptive awareness
The insula has been identified as a key region involved in interoceptive awareness. Whilst imaging studies have investigated the neural activation patterns in this region involved in intero- and exteroceptive awareness, the underlying biochemical mechanisms still remain unclear. In order to investigate these, a well-established fMRI task targeting interoceptive awareness (heartbeat counting) an...
متن کاملInteroceptive cortex in the posterior insula: comment on Garcia-Larrea et al. 2010 Brain 133, 2528.
Sir, In a recent publication in Brain, Garcia-Larrea et al. (2010) reported their identification of patients with post-stroke central pain and selective thermosensory dysfunction, but without other somatosensory abnormalities, and they suggested that the basis for such dissociated symptoms might be the presence of a 'third somatosensory area' specifically supporting temperature sensation in the...
متن کاملAltered insula activation during pain anticipation in individuals recovered from anorexia nervosa: evidence of interoceptive dysregulation.
OBJECTIVE Recent evidence raises the possibility that symptoms of anorexia nervosa (AN) could be related to impaired interoception. Pain is an interoceptive process with well-characterized neuroanatomical pathways that may overlap to a large degree with neural systems that may be dysregulated in individuals with AN, such as the insula. METHOD Functional magnetic resonance imaging (fMRI) was u...
متن کاملInteroceptive Awareness and the Insula – Application of Neuroimaging Techniques in Psychotherapy
Interoceptive awareness is defined as the awareness of stimuli originating inside one’s own body such as the heartbeat. The emergence of new brain imaging techniques like functional magnetic resonance imaging (fMRI) or magnetic resonance spectroscopy (MRS) has increased our knowledge of neural substrates underlying interoceptive awareness. In particular, the bilateral brain structure of the ins...
متن کاملMindfulness-based training attenuates insula response to an aversive interoceptive challenge.
Neuroimaging studies of mindfulness training (MT) modulate anterior cingulate cortex (ACC) and insula among other brain regions, which are important for attentional control, emotional regulation and interoception. Inspiratory breathing load (IBL) is an experimental approach to examine how an individual responds to an aversive stimulus. Military personnel are at increased risk for cognitive, emo...
