About Interoception and It’s Importance
Interoception (some may also call it neuroception) is the conscious detection and perception of sensory signals in the body and on the skin. Most often these signals are processed as sensations. Sensation, as the foundation of emotional experience, is always there in our bodies; however, we are not always fully conscious of its existence or its experiential range. 
Perceived interoceptive sensations may be extremely subtle, thus requiring considerable practice and mind training for conscious registering of these body-based “feeling.” Sometimes, awareness of interoception can be highly dramatic like sharp crushing chest pain in heart attacks and severe autonomic reactivity in panic attacks. Perceived interoceptive sensations are always evaluated cognitively. Some interoceptive experiences may be evaluated autonomically via limbic system and stress response system activation. Once we are aware, we evaluate consciously. Western neuroscience has strong interest in neuroception for embodied contemplative experience as well as for clinical applications. Self-sensed bodily sensations are coded as pleasant, unpleasant and neutral. These are the same categories used in Buddhism to evaluate personal sense-door experience in life: pleasant, unpleasant, and neutral.
There are neuro-anatomical pathways interacting between and among externally based sensory experiences (thalamic processing of external sensory perception regarding seeing, hearing, feeling, smelling, and tasting) and internal “felt-sense” experiences of inner body sensations. This is highly complex processing. Afferent sensory signals communicate with higher order cognitive and affective brain regions and processes; these brain-body-mind-heart interactions provide direct understanding of self in context with environment, personal history, emotions, and goal-oriented behaviors. In times of extreme stress and/or personal danger, interoception may be an early warning signal for unsafe conditions and the possibility of physical harm or death. In substance use disorders, interoception may serve dual purposes: crav
ing and strong discomfort signal the need to ingest mind-altering substances, or an early warning signal to modify your current
situation or condition to avoid relapse. In mindfulness training such as still and moving meditation or yoga practice, interoception can guide us in breathing, being still, and bodily movement and awareness. Key clinical conditions (anxiety, depression, trauma, substance misuse, and eating disorders) include subtle and not-so-subtle interoceptive experiences – often leading to a multitude of self-medication behaviors to avoid unpleasant experiences. With training and personal experience, interoception may help us with bio-psycho-social-spiritual realities and self-regulated emotional balance. Even the human face plays a role in interoception. Facial emotions are powerful influencers (proprioceptive feedback) in brain-mind experiences of emotional life. These experiences are intrapersonal and interpersonal in nature, and their “felt-sense” tends to be quite subtle.
Neuroscience research tends to examine coherence between interoceptive awareness and self-reported experiences in the
body. Physiological measurement and cognitive self-report are examined. Narrowed focus of attention on soft signals
(threshold sensitivity to feelings of well-being, mood, heart rate, respiration rate and depth, body temperature, etc.) are
the subjects of various studies. Thus far most outcomes do not support the premise that experienced meditators and yogis have superior interoceptive detection skills. Although these practitioners in their own experience believe that they do have stronger sensitivity to “picking up” interoceptive signals. Based on my own experience, I think their assumption is correct. This question will remain in limbo; generally, experienced practitioners do perform better in detection here, but the differences between groups of subjects tends to be non-significant. Some studies note that with a greatly expanded number of subjects, the differences may well fall into the statistically significant range. This may be a measurement and target sensitivity issue. Or, mindfulness practice with its brain plasticity changes may not lead to superior neuroception.
In practical terms related to clinical interventions, such practices as Dialectical Behavior Therapy, Mindfulness-Based Stress Reduction, Acceptance and Commitment Therapy, Feldenkrais, Alexander Method, Focusing, Somatic Awareness, and Hakomi Breath Training all appear to produced heightened sensitivity to interoceptive awareness. Practice makes perfect!
