In 1890, William James famously declared in The Principles of Psychology that “Everyone knows what attention is”. Attention has become a catch-all term for how the brain processes its own information, and its effects can be measured through behaviors, electrophysiology, and … Continue reading A taxonomy of attention
Memory is essential to all our lives. Without a memory of the past, we could not operate in the present or think about the future. We would not be able to remember what we did yesterday, what we have done … Continue reading How human memory works?

The Fourier transform is a mathematical technique that allows an MR signal to be decomposed into a sum of sine waves of different frequencies, phases, and amplitudes. This remarkable result derives from the work of Jean-Baptiste Joseph Fourier (1768-1830), a … Continue reading Understanding the Fourier transform
The Approach The main goal of this post is to explain how to convert OpenBCI datasets in EDF format files in a simple, easy and straightforward way. Many researchers and programmers have shared their files and software, either on an … Continue reading ASCII to EDF format converter
It is known that EEG data is often corrupted by different types of artifacts. Many efforts have been made to enhance its quality by reducing the artifact. The EEG contains the technical artifacts (noise from the electric power source, amplitude … Continue reading Automated eye blink detection online
About this project What is more exciting than a brain-controlled helicopter battle against two people? We only need two brains, one OpenBCI board, one Arduino board, two digital potentiometers, and two toy helicopters. Are you ready for this? Components and … Continue reading Alpha power battles with toy helicopters
Lab streaming layer is a system for synchronizing streaming data for real-time streaming, recording, and analysis of biodata. Theopenbci_pylsl program uses Python to establish an LSL stream that can be received using scripts in Matlab. Follow the steps below to … Continue reading OpenBCI Lab Streaming Layer (LSL) – From Python to Matlab
