Brain-computer interface (BCI) is a collaboration between a brain and a device that enables signals from the brain to direct some external activity, such as control of a cursor or a prosthetic limb. The interface enables a direct communications pathway between the brain and the object to be controlled. In the case of cursor control
BCI or DNI is a direct communication pathway between an enhanced or wired brain and an external device. DNIs are often directed at researching, mapping, assisting, augmenting, or repairing human cognitive or sensory-motor functions.
This document discusses brain-computer interfaces (BCIs). It begins by explaining that BCIs allow users to control devices through brain activity measured by electroencephalography (EEG) or single-neuron recordings, but both methods have disadvantages. The document then demonstrates that electrocorticography (ECoG) recorded from the brain's surface can enable rapid and accurate one-dimensional cursor control. Over brief training periods, patients achieved high success rates in a binary task, suggesting ECoG-BCIs could provide an effective communication option for those with severe motor disabilities. Open-loop experiments also found ECoG signals encoded substantial information about two-dimensional joystick movements.
This document provides an overview of brain-computer interfaces (BCI). It discusses electroencephalography (EEG) and how EEG measures brain electrical activity through electrodes. Different types of BCI devices and electrodes are described. The anatomy of the brain and functional mapping are outlined. Applications of BCI include prosthetic control, communication devices, operator monitoring, forensics, entertainment, health, neuromarketing, and neuroscience. The document also discusses Elon Musk's Neuralink company and its goal of creating brain chips to treat disorders. It concludes with a live demo of a BCI system using an EEG headband and a question/answer session.
This document provides an introduction to brain-computer interfaces (BCI). It discusses how BCI works by using sensors implanted in the motor cortex to detect brain signals which are then translated by a computer into commands. The document outlines different types of invasive and non-invasive BCI and describes several applications including using thought to control prosthetics, transmit images to the blind, or allow communication for the mute. Potential advantages are restoring functionality for the paralyzed or disabled.
1) Brain-computer interface is a direct communication pathway between the brain and an external device that reads brain activity without muscle movements and translates it into commands for computers and other devices.
2) The objective of BCI is to develop a fast and reliable connection between the brain of a severely disabled person and a personal computer to allow communication and control through thought alone.
3) BCI research has progressed from animal experiments to human trials, allowing paralyzed patients to control devices and communicate just by thinking. However, widespread adoption is still limited by challenges with sensor accuracy, information transfer rates, and system costs.

Programming Foundation Models with DSPy - Meetup SlidesZilliz
Prompting language models is hard, while programming language models is easy. In this talk, I will discuss the state-of-the-art framework DSPy for programming foundation models with its powerful optimizers and runtime constraint system.
2. What’s Brain Computer Interface?
• A brain computer interface (BCI), sometimes called
a mind-machine interface (MMI), direct neural
interface (DNI), or brain–machine interface (BMI), is
a direct communication pathway between an
enhanced or wired brain and an external device.
BCIs are often directed at researching, mapping,
assisting, augmenting, or repairing human cognitive
or sensory-motor functions.
3. A brief overview of the history of BCI
• Research on BCIs began in the 1970s at the
University of California, Los Angeles (UCLA) under a
grant from the National Science Foundation,
followed by a contract from DARPA.
• It all started with Hans Berger's discovery of the
electrical activity of the human brain and the
development of electroencephalography (EEG). In
1924 Berger was the first to record human brain
activity by means of EEG.
4. How it actually works?
• Input : Voltage fluctuations arise as neurons
communicate using electrical signals.
• This change, caused by some stimulus, is then
measured using different methods like EEG,
BrainGate, etc., and shown as a point on a graph.
• When you plot many points this way you get your
output, a graph measuring brain activity. The data
represented by the graph can be used to control
devices.
5. • Non-invasive BCIs do not involve neurosurgery.
Types of BCI
• Invasive BCIs are implanted directly into the grey
matter of the brain during neurosurgery.
• Partially invasive BCI devices are implanted inside
the skull but rest outside the grey matter.
6. • In May 2008, researchers at Pittsburgh University
planted an electrode inside a monkey’s skull and
tried to read its brain activity.
Experiments
7. Experiments
• The next year, Honda developed its own brain
computer interface and used it to enable
communication between a human and its
humanoid robot ASIMO using nothing more than
thoughts.
8. Applications
• Medical
• Neuroergonomics and Smart Environment
• Neuromarketing and advertisement
• Educational and self-regulation
• Games and Entertainment
• Security and Authentication
-Basically just describe what’s written on the slide
-Add the “all starts with us military joke”
-Thank Wikipedia
-Mention that this how BCI started off, that this the most basic representation of how brain activity measurement works.
-Mention how small these voltage changes are, which could as low as few micro volts, which tells us why it took so long for bci to emerge
-So much for the boring stuff.
-Any idea what happened next?
-Using monkey as a test subject to see if brain activity can be successfully measured and used to control devices in a way we think.
-Controlling bots with our thoughts, imagine how many lives it can save, we don’t have to send humans into dangerous environments like radioactive regions to clear radioactive wastes, we could send them to outer space or other planets before us to examine its habitability.
-Now comes the part that concerns US the most
-Medical : using brain waves to study and prevent diseases, accidents
-Environment : efficient functioning, measuring stress
-Neuromarketing : calculate attention for ads
-Educational : using invasive bci to improve attention and regulate emotions
-Games : obvious, could also be used for training as a simulator
-Security : using bio signals for authentication, or particular thoughts, if we’re being forced we could send a stress signal, helpful for disabled people
-Let’s see how much of a difference BCI can really make despite it being in very early stage
-Describe how that woman must be feeling and the possibility of people like her using a fully functional BCI exoskeleton in future
-In the last video we saw how our mind can give orders to a device reading our brain waves but that’s not it, we can use the same interface to communicate the other way, in the next video we’ll see a man unable to feel touch, getting that sensation back
-BCI is still a young field There is a lot left to do, there is a lot of room for improvement, there are lots of mistakes to be made, but it can’t advance unless WE, the future, get involved.
-Mind control. What was once dismissed as magic, as impossible is just on the horizon now, it’s up to us to make that as much of a reality as our cell phones. And in time not too long, this science fiction concept will become a science fact, it will literally change the world, and will bring smile to many faces.
