Patryk Laurent

  • I am a cognitive scientist and neuroscientist, working at Brain Corporation in San Diego, California. I study how networks of simulated neurons learn to control themselves and generate end-directed actions -- thoughts, decisions, memory formation, and movement.
  • My team focuses on integrating machine learning algorithms into closed-loop systems so they act on and influence the world that they perceive.

Here is some software I've developed during my research. You are free to use any of this source code in your work as long as you acknowledge me. I hope to get around to selecting a more specific open source license soon.

  • Computational Modeling
  • NNQL

    My project to develop a simple but powerful neural network simulation language inspired by SQL. NNQL minimizes programming time, maximizes clarity of model descriptions, and improves communication between modelers and non-modelers.

    Adaptive Reading Agent Simulator

    (Runs in a GUI) Train a Reinforcement Learning agent to control its saccadic eye movements as it reads words of various lengths and word identification difficulties. Outputs data in MATLAB matrix format for easy analysis.

    Recurrent McCulloch-Pitts Network

    Train and test a Levy-style recurrent neural network of spiking McCulloch-Pitts neurons.

  • fMRI
  • SVM Weight Extractor

    Handy script that extracts weights from the SVM generated by MATLAB's bioinformatics toolbox so you can look at the value of your decision variables.

    ASL Eye Tracker Driver

    This Java code allows you to get gaze information from ASL eye trackers via a serial port connection for gaze-contingent paradigms. It interprets the binary data from the controller.

    EPI Noise Echo Cancellation

    If you need to hear your participant in real time during your fMRI experiment, this ChucK script allows you to cancel out the scanner noise during EPI data acquisition.

Dr. Patryk Laurent holds an B.A. in Cognitive Science and a Ph.D. in Neuroscience, with a focus on the cognitive and computational neuroscience of learning. He has studied neural network models of hippocampus, a part of the brain that plays an important role of learning and memory. He has also studied how reward can lead to the control and coordination visual attention and saccadic eye movements. Prior to his scientific career, Dr. Laurent spent 6 years as a professional software developer working in internet-based publishing, communications, and data analysis sectors.

Dr. Laurent is an expert in understanding how minimally designed artificial neural network systems can learn to control themselves, interact with the world, and generate intelligent behavior.
