Using matlab and EEGLAB, I generated my own simulated EEG data, according to the classical theory of event related potentials (ERP). ERP are small voltages generated in the brain in response to specific events or stimuli.

The theory states that peaks in ERP waveforms reflect phasic bursts of activity in one or more brain regions that are triggered by experimental events of interest. It is assumed that an ERP-like waveform is evoked by each event, but that on any given trial this ERP “signal” is buried in ongoing EEG “noise”.

Generating a single trial of EEG

The simulated data is generated by adding signal and noise…

A Fully Automated Unsupervised Blink Detection Algorithm

EEG signals are vulnerable to distortion caused by other interfering electrical fields. For instance, blinking, where the retina and cornea form an electric dipole. Blinking is known to contaminate signals and impact decoding processes in medical and scientific applications.

Mohit Agarwal and Raghupathy Sivakumar of the Georgia Institute of Technology considered blink detection to remove blinks from EEG signals and proposed a fully automated and unsupervised algorithm, Blink.

Blink self-learns user-specific brainwave profiles for blinks and works with both user training and manual inspection requirements. …

If you could have a superpower, what would it be?

Flying? Shape-shifting? Mind-reading? Telepathy? Telekinesis?

Well, what if I told you, you could?

Enter Brain Computer Interfaces. But first, a brief introduction to:

The most complex object known in the universe 🧠

The brain. The wondrous organ that is the source of our identities and consciousness. The brain oversees all bodily functions, from our thoughts and speech to our organ systems. It dictates intelligence, emotion, and creativity, allowing us to move forward as a species.

The brain receives information through our five senses, assembles it in a way that has meaning for us, and stores it into our memory…

The Next Step in Developing Preventive and Curative Gene Therapies

Diseases such as cystic fibrosis, Huntington’s disease, Tay-Sachs disease, sickle cell disease, and several types of cancer are hereditary, meaning they can be determined by genetic factors passed on from parents to children.

These diseases severely impact the quality of life of not only the people suffering from them, but their families, friends, and caretakers as well.

Due to the genetic nature of these diseases, certain people have an increased likelihood of getting them. …
