- can capture motor signals in brain to control an avatar: guy in fMRI machine in Israel sees through a robot’s eyes in France, moves toward beckoning person
- brain can incorporate prosthetics, iphone as if it were part of your body
- brain jelly grows connections like a human brain…
synthetic telepathy: brain reacts the same way to a real sound and an imagined sound (the latter is weaker)
Transcranial Direct Current Stimulation (tDCS):
- direct current, can induce specific things based on placement on head
- anode on right temple and cathode on left shoulder > facilitates learning; much less anxiety/self-judgement/negative thoughts > able to perform better
- electrodes can send signal to brain
- top of head, bottom of back of head, can control stress
Binaural beats
- Use wave interference principle to create a third wave: two waves (one through each ear) combine, creates third wave that entrains brain
- doesn’t go far past primary auditory areas
Ultrasound
- sound at a high frequency (above what we can hear, >20,000 hertz)
- 2 million hertz; mechanically vibrates cells to increase/decrease activity

- Noninvaisve neuromodulation:
- TMS: strong magnetic coils
- tDCS (consumer grade available)
- Foc.us, Thync
- transcranial ultrasound
- mood enhancement:
- frontal cortex involved in mood
- focused ultrasound device targets right frontal cortex, makes subjects feel better
- depressed people have more DMN, especially negative emotion circuits; decreased activity in cognitive control centers
- frontal cortex stimulation produces opposite effect
- mood enhancement:
- Noninvaisve neuromodulation:
Loving compassion meditation: improves mood, changes baseline level of emotional state
Meditation is like auto-hypnosis, but is active: internal wakefulness
