Pneumogastric NervePneumogastric Nerve• Charles Darwin (1872): • The Expression of
Emotions in Man and Animals– Heart, guts and brain
communicate intimately via the "pneumogastric" nerve, the critical nerve involved in the expression and management of emotions in both humans and animals.

Lifestyle treatment of depressionLifestyle treatment of depression• Inflammatory theory of depression
– Acute stress is manageable. HPA system swings into gear with sympathetic nervous system response followed by parasympathetic relaxation and repair phase.
– Chronic stress is bad. Stress (current and unresolved), inactivity, poor sleep, poor diet, toxic load (tobacco, alcohol, obesity), sympathetic overdrive. → HPA axis dysfunction.
– HPA dysfunction leads to inflammation – body and nervous system.
– Pro-inflammatory cytokines.

Engaging young people in using a Engaging young people in using a breathing-relaxation techniquebreathing-relaxation technique
• “Has a teacher or counsellor ever taught you how to use slow breathing techniques to help…”
• “yeah, I’ve tried that – it doesn’t work for me!!”
• OK I believe you – it hasn’t worked for you when you’ve tried it – up to now. But actually it has worked for you when you haven’t tried it – I’ll tell you why… {come in with the sales spiel}
““The Spiel”The Spiel”• Draw brain and spinal cord plus eye and optic
nerve and schematic body with heart, lungs, guts, diaphragm muscle.
• within brain draw brainstem = autonomic N.S. “autopilot” = ‘reptilian brain’
• draw hemispheric limbic system with amygdalas (‘alarms’) = ‘mammalian brain’
• draw frontal lobes = ‘thinking/verbal brain’• Describe fight/flight/freeze
• Sympathetic N.S., adrenalin, amygdalas, frontal lobes switch off = ‘survival/stress N.S.’
• Need a circuit breaker to turn it off = parasympathetic “peaceful N.S.” = vagus nerve
Breath and the Vagus Breath and the Vagus NerveNerve
• Vagus nerve = feedback from diaphragm– amygdalas will listen– “I know for certain you already use this breathing-
relaxation technique!”– ??? (their expression)– yawning, sighing, laughing, sobbing…yawning, sighing, laughing, sobbing…– the ‘valsalva manoevre’ stimulates vagus.
• Enact a yawn, sigh etc– how this is same as a “yoga breath”– dogs, chimpanzees – use of yawning as
communication– humour helps!!

Breath and the Vagus NerveBreath and the Vagus Nerve• “victorious”
Breath and the Vagus NerveBreath and the Vagus Nerve• Elite athletes are trained to use it.
– AFL/NRL footballers lining up for goals– Olympic runners & swimmers– Johnny Wilkinson in Rugby, David Beckham in Soccer
• Singers and performers e.g. Australia’s Got Talent, X Factor etc
• Politicians making speeches– Julia Gillard speaking with slow diaphragmatic breathing and
exaggerated Australian drawl
Breath and the Vagus NerveBreath and the Vagus Nerve• Show how similar “breathing-relaxation” is to
yawning.– the sound “ocean breathing” on the lengthened out-
breath.
• Practice it in session (incl parents)
• Self-disclosure– for sleep, daily stress, exams etc– You shouldn’t preach this if don’t practice it!

Lifestyle treatment of depressionLifestyle treatment of depression• Sleep
– Draw graph sleep architecture – level 1 to 4– Explain value of deep sleep – cell repair, clear inflammatory debris
(cytokines)– EEG patterns – delta rhythm stage 4.– CSF flushing of neurons with resolvins - clean out debris– Teens need 9 ½ hrs average for full dose stage 4 ‘hardware’ clean up
and full dose REM stage 1 dreaming “software’ cleanup.
• Circadian Rhythm– Pineal gland, Supra-chiasmatic nucleus (SCN)– Melatonin = sleep chemical, SCN = clock– Need for sunshine in day and darkness at night– Computer/TV @ night (blue light/amber glasses)
• ISRT – Interpersonal Social Rhythm Therapy

Lifestyle treatment of depressionLifestyle treatment of depression• Exercise
– Superoxide Dismutase (SOD)– Brain derived neurotrophic factor (BDNF)– Tiredness to help sleep– Better insulin sensitivity, energy and weight control– Endorphins for mood
• Diet– Omega-3/omega-6 ratio of 1:1 in paleolithic hunter gatherers– Omega-3 building blocks for “resolvins” & neuroprotectin– Sugar, metabolic syndrome and inflammation– Nutrients, including antioxidants, and protein – lean meat, vegetables,
fruit, berries, nuts

• Attachment and socialising– Friendships – face-to-face– Talking therapies
