- - - - BDNF
        
        increases voltage and signal strength at synapse
        
        activates genes to produce more of itself and serotonin
        
        mice love running. the more they ran, the higher the BDNF (43)
        
        in hippocampus, nourishes neurons like fertilizer
      - Neurogenesis
        
        neurons born as blank-slate stem cells, so need to find something to do (fire its axon) in order to survive - 28 days for fledgling cell to plug into a network (use them or lose them)
        
        neurons grow back (in hippocampus)
  - - - heart muscle tissue releases atrial natriuretic peptide (ANP) in proportion to HR, which puts the brakes on the HPA axis
      - lowers resting tension of muscles, interrupting anxiety feedback loop to the brain (calm body calm mind)
    - - neurogenesis, grow new connections and neuroplasticity, create positive memories that detour around the fear
      - Anxiety sensitivity: HR/breathing increase for unrelated reason, awareness of this physical arousal can trigger a state of anxiety/panic (78)
  - - - kill pain
      - produce euphoria
- - - - less prone to startle or react out of proportion
      - feel less irritable
      - easier to wake up?
      - Locus coeruleus regulates breathing, waking, heart rate and blood pressure; monitors blood pH and is the origin of the alarm signals that trigger the amygdala in a panic attack (85)
- - - - dopamine is for movement too
      - hyperactivity - stimming/fidgeting to focus
