Electrocephalography

• Electrical activity in your brain

• The electrical signals that pass between your brain cells

• scalp pick up these signals through small wires

Transcranial focused Ultrasound

• MIT 2026 new breakthrough to consciousness study

  • Transcranial Focused Ultrasound (tFUS)

  Transcranial focused ultrasound is noninvasive and reaches deeper into the brain, with greater resolution, than other forms of brain stimulation.

Neuroscience theories of consciousness:

• Theories of the neural substrate that required to produce consciousness:

• Global Neuronal Workspace Theory (GNWT)

• You become conscious of something when information gets broadcast to the whole brain, not when it stays local.
