The BrainCode Games


The BrainCode Games is a hackathon, a kind of collaborative competition, which ultimate goal is to develop a solution to an open problem in a short period of time (but very much intense!). The idea of The BrainCode Games is to use Artificial Intelligence to solve a Neuroscience problem. Don’t worry if you feel lacking the required knowledge or skills. The final objective of this hackathon is that you learn, in a didactic, practical and fun way, about some hot topics of the field (artificial intelligence, neuroscience and programming). For this reason, we will organize a series of lectures before the event that you can follow remotely. You will receive an attendance certificate for training and participation hours. And there will be awards for the team with best results.

Sign up (Closed)

If you are interested, sign up using the following form, and follow us in Twitter and Instagram. We will post important information related to the event and the topics that will be covered. Ah! Don’t worry if you don’t have a team, we will match you with the person that better complements your skills :P

…the open problem

The problem consists in detecting certain events from electrophysiological signals (which are recordings of the brain activity). These events, called sharp wave ripples or just ripples, are a kind of fast oscillations as those shown in the picture below. They appear repetitively in a region of our brains dubbed hippocampus, which is responsible for consolidating memories. Studying ripples is critical for us to better understand the underlying mechanisms of memory and many laboratories around the world focus their research on these events. It has been proved that interrupting ripples prevents memories from getting formed, and that prolonging them may improve memory.

The biological signal where we can see ripples is known as Local Field Potential or LFP. This is a kind of local EEG (or electroencephalogram). Neurons are constantly interchanging ions and this electric flow is translated into an electric potential that together with those emanating from surrounding regions, create an electrical signal which can be detected by our measuring devices. Therefore, the LFP is a signal that represents the overall neural activity of the many neurons that are around the area where the measurement electrode is placed. In the picture above, we can see 8 aligned electrodes recording the LFP at different equally spaced locations of the hippocampus.

Ripples are generated in the hippocampus, a very primitive brain region with roles in memory and spatial information processing (tasks such as creating a mental map of the world, orientation, etc). Hippocampal neurons are distributed in such a way that individual electric potentials add each other, making easier to see oscillations in the LFP.

Well! The goal of this hackathon is to develop an algorithm based on artificial intelligence and machine learning techniques, capable of detecting ripples in time series such as the LFP (sampled at 1250 Hz). In order to accomplish this, we will provide you a database with LFP recordings and the times of ripples manually annotated by our expert. You are free to use any supervised learning approach for addressing the challenge.

All these topics will be covered in detail in a series of lectures.

…the hackathon

Hackathon was a term originally coming from the hacker community and used to refer to a meeting of programmers enrolled in a collaborative challenge. These events usually last between two days and a week. Some of them have educative or social purposes, but in most cases the goal is to create functional software. In our case, the purpose is both to apply AI tools to neuroscience and also to teach these techniques in a didactic way :)

This term lumps together the concepts of marathon and hacker, as a reference to a collective experience with the common goal of developing applications in a collaborative way in a short amount of time. From an educational perspective, this kind of event represents a pedagogical tool, since it promotes collaborative work among peers aimed to problem solving; it focuses on the working process as an instance of learning and facilitates intrinsic motivation in participants.

Hackathons are, moreover, an increasingly common hiring method in business.

…the lectures

There will be three lectures which can be followed online and offline:

The purpose of all lectures and materials uploaded to this web is to provide you some sort of guide so you can take a deeper look into these topics on your own.
