Right now neurotechnology can turn signals to text an able to perform few task with robotic arms or even similar to control the external computers with thoughts like a research published in 2018 showcased a BCI which allowed participants to engage with android tablet and use several applications including typing searching web, sending mails, watching youtube etc.

We may still be several years away from being able to send a thought directly though. Cognitive enhancement the ability of improve or quote “Upgrade” the brain, previously was a sci-fi has become real. Neurostimulation the ability to directly send signals to brain using electrons is also be used in improving performance in human perception, learning, memory, attention, and decision making.

Questions you need to ask in BCI

There are three types of neurotechnology

  1. Non-invasive: It means totally outside of the body and nothing is penetrated (no implants)
  2. Semi-invasive: Its bit inside in the body like under the skin over the scalp
  3. Invasive: Means Inside the body connected to your brain and penetrated.

As we hear lot of these words in economics or trading market that With great risk you have biggest reward. In similar If you get an implants Its easy to get clear and much better neural signals (less noise). if you decrease the risk like go for semi invasive you get bit lesser quality neural signals and vice versa happens with non-invasive. But no worries yet, many scientists and great organizations with greatest brains working to bring the non-invasive tech up to the level of invasive. Its not so far, Join the team and do contribute your part to make it happen earlier. Before that let us know what kind of technology is exists currently. By the time you read there might be many. Point,

Commonly used non-invasive

EEG (Electroencephalography) fMRI (Functional Magnetic Resonance Imaging) fNIRS (Functional Near-Infrared Spectroscopy)
Measure Electrical activity (By placing electrodes on the scalp) Blood oxygenation (Blood flow in the brain to gather signals. In short, more blood = the area more activated) Blood oxygenation (Middle ground of EEG and fMRI. Based on the absorption of near infrared light by hemoglobin in blood)
Spatial Low (millimeters) High (millimeters) Low (centimeters)
Temporal High (milliseconds) (real time: faster) Low (seconds) High (milliseconds) (real time: faster)
Hemodynamic No Yes Yes
Portable Yes (some devices) No Yes
Cost Low High Low-Moderate
Safety Safe Safe Safe
Application Clinical, Cognitive, Neuropsychology Cognitive, Neuropsychology, Clinical Clinical, Cognitive, Neuropsychology
