❗ Information

Small summary

✒️ -> Scratch Notes

Gain experience with hardware (Muse, OpenBCI)

Neurotech:

• Device that interfaces with the Central Nervous systems
• Includes imaging and stimulating CNS

Neurotech includes:

• Brain Computer Interfaces (BCIs)
• Neuroimaging
• Neuroprosthetics
• Neurostimulation (Deep Brain Stimulation)

Uses:

• Recreational
• Cognitive Enhancement
• Rehabilitation
• Restoring Function
  Deep Brain Stimulation (DBS), Neuroprosthetics, Neuralink, Cochlear Implants

Brain Computer Interface (BCI):

• Acquires brain signals, analyzes them, and translates them into commands that are relayed to an output device to carry out a desired action

Applications of BCI:

• Communication
• Movement
  • Prosthetics
  • Locomotion
• Neurorehabilitation
• Recreational

How does it work:

Signal Acquisition -> Signal Processing -> Device Interface -> Assistive Device -> (feedback) -> Mental Task

Restart Process, it’s a loop

1. Signal Acquisition

   • Noninvasive:

     • EEG
       • Electroencephalogram
     • MEG
       • Magnetoencephalography
     • fMRI
       • Functional Magnetic Resonance Imaging
     • PET
       • Positron Emission Tomography
     • fNIRS
       • Measures blood oxygenation in the brain, similar to fMRI.
       • Functional Near Infrared Spectroscopy

   • Invasive

     • ECoG
       • Electrocorticography
       • Intracranial EEG basically
     • Implanted Electrodes, arrays

Factors to Consider:

• Invasiveness
• Signal Accuracy
• Spatial Resolution
• Temporal Resolution
• Cost

Electroencephalogram (EEG):

• Measure of electrical activity in the brain
• Picks up activity frm groups of neuron
• On-scalp electrodes
