Brain to Brain Interface
The document discusses telepathy, defined as the communication of information between individuals without sensory channels or physical interaction, and notes the lack of scientific evidence supporting its existence. It elaborates on the development of brain-computer interfaces (BCIs) and brain-to-brain interfaces (BBIs), which allow for direct communication between brains using technology like EEG and TMS. Potential applications include criminal investigation, communication aids for the differently-abled, and capturing memories, with prospects for future advancements in communication technology.

- 2. Telepathy ? •It’s the purported transmission of information from one person to another • without using any of our known sensory channels or physical interaction. • There is no scientific evidence that telepathy is a real phenomenon.
- 3. How will itbe if you are going to have a real technology that will enable you to communicate just through thinking ?? Do you think so that it’s even possible ???
- 4. YES !!! Ithas become ALMOST possible Through ..... BRAIN TO BRAIN INTERFACE
- 5. Brain –Computer Interface A brain–computer interface (BCI), sometimes called a direct neural interface or a brain–machine interface, is a direct communication pathway between a brain and an external device.
- 6. Types of BCI Invasive Brain Computer Interfaces -implanted directly into the brain and has the highest quality signals. -provide functionality to paralyzed people. Partially Invasive Brain Computer Interfaces -implanted inside the skull but outside the brain. Non Invasive Brain Computer Interfaces -Gives a patient the ability to move muscle implants and restore partial movement.
- 7. Invasive Partially Invasive Non Invasive
- 8. Shift from BCIto BBI • A BBI relies on two pillars: - the capacity to read (or “decode”) useful information from neural activity and the capacity to write (or “encode”) digital information back into neural activity. • In recent years, we have witnessed incredible progress in these two capabilities with the development of Brain-Computer Interfaces, or BCIs
- 9. Working of BBI • Electroencephalography, or EEG, is routinely used by clinicians and researchers to record brain activity noninvasively from the scalp. • The first human brain (the sender) is connected to a computer via an EEG-based BCI. The second human brain (the receiver) is connected to another computer via a Magstim transcranial magnetic stimulation (TMS)
- 10. The cycle ofthe experiment. Brain signals from the “Sender” are recorded. When the computer detects imagined hand movements, a “fire” command is transmitted over the Internet to the TMS machine, which causes an upward movement of the right hand of the “Receiver.” This usually results in the “fire” key being hit.

- 12. Applications • Criminalinvestigation • Communication • Aid for the differently-abled • Capturing memories ..etc
- 13. Future ...? •Great !! Instead of posting it in Facebook or in Twitter one can post a message directly into your brain ! Haha • Light weight EEG seems possible • Constant streaming of thoughts • Less bulkier BBI

- #12 The words (“hola” and “ciao”) as binary strings and presented them as a series of cues on a computer monitor. They recorded the subject’s EEG signals as the subject was instructed to think about moving his feet (binary 0) or hands (binary 1). They then sent the recorded series of binary values in an email message to researchers in France, 5,000 miles away. MRI image showing location of TMS phosphene generator (credit: Carles Grau et al./PLoS ONE) There, the binary strings were converted into a series of transcranial magnetic stimulation (TMS) pulses applied to a hotspot location in the right visual occipital cortex that either produced a phosphene (perceived flash of light) or not.
