Mobile health and the brain

Context• 10 essentials for brain performance– Diet– Removing negative thoughts – Exercise– Brain nutrients– Positive peers– Clean environment– Sleep (Zeo, FitBit)– Brain protection– New learning– Stress management

Outline

• Diagnostics and passive training• Active modification

Diagnostics and passive training

• Indirect and direct measures of brain function via biofeedback and neurofeedback

• HPA axis– Growth vs. Defense– Anabolic vs. Catabolic– Rest/Digest vs. Fight/Flight– Parasympathetic vs. Sympathetic– Stressed vs. Relaxed– Endorphins/HGH/GABA/Serotonin vs.

Cortisol/Adrenaline

Biofeedback (Heart-rate monitoring)

• Provide a heads-up, real-time display of how the brain is doing

Active modification

• Using computer-controlled external signals to modify brain activity– Audio– Electrical– Magnetic

Audio: Binaural BeatsFor example, if a frequency of 100 Hz is played in one ear and 107 Hz is played in the other ear, a binauralbeat of 7 Hz is created by the brain.Brain waves match or “follow” the binaural beat. Ifthe binaural beat is 7 Hz, an increase in brain waves of 7Hz occurs.

Brainwave states

Electrical: tDCS, tACS

• Transcranial Direct/Alternating Current Stimulation (tDCS/tACS)– ARP POV– High-performance activities– Neurological disorders

Magnetic: TMS, SomaPulse

• Transcranial Magnetic Stimulation– Used to stimulate stem-cell production– Trials for treating Alzheimer’s
