Neurophysiology Menu A list of popular Neurophysiology topics.

---

Beginner neurophysiology **These topics are usually suitable for people new to mindfulness when explained simply, practically and without too much technical language.**

---

Attention How the mind selects, follows and returns to experience. Mind-wandering The natural tendency of attention to drift into thought, memory, planning or imagination. Returning attention The practice of noticing distraction and gently coming back. Stress response How the body and mind respond to pressure, demand or perceived threat. Arousal The level of activation, energy or alertness in the body and nervous system. Settling Allowing the body and mind to become a little steadier, without forcing calm. Grounding Using body contact, sounds, sight or the environment to support steadiness. Body awareness Noticing sensations in the body as part of present-moment experience. Breath awareness Noticing the breath as a possible anchor for attention. Choice and comfort Understanding why people need options in posture, eyes, breath focus and practice style. Cognitive load Why too much information can make attention and learning harder. Habit and reaction How repeated patterns can shape responses before we consciously choose. Pause and response How a brief pause can create more space between trigger and action. Emotion and body sensation How emotions often involve sensations, movement impulses, thoughts and meanings. The brain-body connection Understanding that mindfulness involves both mental and physical experience.

Intermediate neurophysiology **These topics usually need more explanation, examples or teacher experience.**

---

The autonomic nervous system The system involved in arousal, energy, rest, recovery and bodily regulation. Sympathetic activation The branch often associated with mobilisation, energy, effort and threat response. Parasympathetic activity Processes associated with rest, digestion, recovery and calming, though not simply “the relaxation system.” The vagus nerve A major nerve involved in body-brain communication, often discussed in relation to regulation and social connection. Interoception The ability to notice internal body signals such as heartbeat, breath, tension, temperature or gut sensation. Exteroception Awareness of the external environment through sight, sound, touch and other senses. Proprioception Awareness of body position, movement and posture. Orienting Turning attention toward the environment to understand where we are and what is happening. Emotional regulation The ways people influence, relate to or recover from emotional activation. Co-regulation How another person’s tone, steadiness, pacing or presence may influence how safe or settled we feel. Window of tolerance A teaching model for understanding when people may feel within, above or below their workable range of activation. Neuroplasticity The brain and nervous system’s capacity to change through experience, learning and repeated practice. Attention regulation The ability to direct, sustain, shift or widen attention. Executive function Mental capacities such as planning, inhibition, flexible attention and working memory. Default mode network A brain network often discussed in relation to self-referential thinking, memory and mind-wandering. Salience network A network involved in detecting what seems important or relevant. Insula and body awareness A brain region often discussed in relation to interoception and subjective body awareness. Amygdala and threat detection A brain structure often discussed in relation to threat, salience and emotional learning.

Advanced neurophysiology **These topics usually require more care, context and accurate framing.**

---

Polyvagal theory A theory about autonomic state, social connection and threat response that is influential but should be presented carefully and not as settled fact. Vagal tone A measure often discussed in relation to regulation and flexibility, but easily oversimplified. Heart rate variability Variation in time between heartbeats, sometimes used as an index of autonomic flexibility, but not a simple measure of calm or mindfulness. Predictive processing The idea that the brain actively predicts and interprets experience rather than simply recording the world. Allostasis The body’s process of maintaining stability through change, anticipation and adaptation. Allostatic load The cumulative cost of repeated or chronic stress and adaptation demands. Neuroception A term from polyvagal theory referring to the nervous system’s detection of safety or threat, requiring careful explanation. Trauma and the nervous system A sensitive area requiring humility, care and appropriate referral boundaries. Dissociation and shutdown language Terms that should be used carefully and usually only within appropriate professional context. Pain and the nervous system Understanding pain as involving sensation, attention, meaning, emotion and nervous system processing. Inflammation and stress A complex research area sometimes linked with chronic stress, health and wellbeing, requiring careful framing. Hormones and stress Topics such as cortisol and adrenaline, which can be useful but are often oversimplified. Brain networks and meditation Research on how meditation may relate to brain networks, attention and self-referential processing. Long-term practice and brain change Research suggesting associations between practice and brain function or structure, without implying guaranteed transformation. Altered states and physiology Changes in attention, body sensation, emotion or perception during deeper practice, requiring careful grounding. Clinical neuroscience claims Claims about treatment, diagnosis or clinical benefit, which should be handled with caution and usually avoided in general teaching.
