How does the brain secrete the mind? This course will introduce you to the ideas and methods in computational cognitive neuroscience that have been applied to answering this question. Specifically, we focus on simulating cognitive and perceptual processes using neural network models. These models provide a bridge between behavioral and biological levels of analysis. We start by understanding the basic computational and biological properties of individual neurons and networks of neurons, which give rise to basic processing mechanisms like spreading activation, inhibition, and multiple constraint satisfaction. We then discuss learning mechanisms (self-organizing and error-driven), which all networks of neurons require to perform any reasonably complex task. We will examine a range of cognitive phenomena within this framework, including attention, memory, language, and higher-level cognition. The overarching goal is to use simulations to help us to understand how our neurons give rise to our thoughts.
Due to the scope of topics covered and diversity of student backgrounds, we do not have formal prerequisites for this course. If you are a Psych major, typically you will have had the relevant PSYC 1001 (intro), 2145 (cognitive), 2012 (bio), and 3101 (stats), which provide basic background in cognitive psychology and neurobiology that will be useful for the course. Neuroscience majors also will have had relevant coursework and should be in fine shape. Computer science / math / etc students may not have had as much Psych and Neuro background, but we make every attempt to keep everyone on the same page, and the textbook does not assume significant background knowledge. Students who have a sincere interest and/or additional background in cognitive psychology, neuroscience, and/or computers (or their relationships) will find this course more engaging. While the models we will be using are mathematically based, only algebra and some simple calculus-level concepts are discussed (and no actual math is required from undergraduates -- grad students are expected to solve a few simple algebra equations). The focus will be on intuitive and practical applications, not on theoretical derivations. Computer programming experience is not required, because the models are accessible via a graphical interface, but it is beneficial, especially for more ambitious final projects.
There is a weekly two-hour lab session that is supervised by the teaching assistant, where students obtain in-depth hands-on experience with the computer simulation explorations. These explorations are the centerpiece of the course, and provide a unique exploratory learning opportunity. You will perform many what-if scenarios to understand what aspects of the brain's biology are important for producing specific cognitive phenomena. You will simulate the effects of brain damage in these models, to understand neuropsychology (the study of brain-damaged patients). The computer models enable complete control and dynamic, colorful visualization of these explorations, providing a unique ability to understand how cognition emerges from the brain. You will document these explorations by answering the simulation exercises questions (to be worked on during the lab sessions). You should be able to do most, hopefully all, of the required homework during these lab sessions.
Lab does NOT meet the first week of class -- starts up the 2nd week when there are actual homeworks to be done.
Tutorials for developing your own network in Emergent:
Your grade will be based on three components in the following proportions:
- Simulation exercises: 50%
- Reading reactions: 10%
- Final project: 30%
- Class participation: 10%
The simulation exercises are linked in several places: where they fit within the flow of the chapter, at the end of each chapter, and in this master list: http://grey.colorado.edu/CompCogNeuro/index.php/CCNBook/Sims/All . You should answer all of the exercise questions for each chapter, and submit to the class Canvas site on or before the date shown in the schedule below. Although you will be working on these exercises in the labs, you must write them up individually. We want to see that each person individually understands the material, so this should be evident in your writeup. It is best to write down results and first drafts of answers as you work through the exercises -- they can take a while to run and you don't want to have to run them repeatedly. Exercises turned in late will be penalized 5% for each day after the due date.
Important: -- in the Neuron exercise, the questions marked advanced are only required for graduate students -- undergrads are welcome to do them if you want, but they are not required. These are questions 2.4 and 2.6.
For each chapter in the online Computational Cognitive Neuroscience Textbook, you write up a few sentences about the topic you found most interesting in the chapter and why, and in particular any interesting questions that occurred to you that might be useful to discuss during class (for shy students, this can also be a great way to ask your questions and can really help with your participation grade if you otherwise don't feel comfortable participating in discussions during class). These reading reactions are designed to ensure that you are keeping up on the reading and to inform us about your interests. Reading reactions should be submitted to the Canvas system for this course, prior to the class meeting when they are due (i.e., by 12pm noon).
The final project is an opportunity for you to use simulations to examine some psychological phenomenon of interest to you. This project will require careful preparation and thought, so I strongly recommend that you begin your work early. Do not be overly ambitious -- relatively clear and simple but thoughtful work is preferred to a complicated half-baked mess. Do not be misled by the relative simplicity of running the canned exercises in the book -- simulation projects take a long time to complete! The following timeline is designed to ensure that you make progress on your project (5 of the 30 points for the project will come from simply making each of the 5 deadlines before the final due date) and that you receive feedback on it before turning in the final version. See the schedule section below for the exact dates of each of the events, indicated by the Deadline keyword.
|Today!||Project topic version 1 -- just a quick idea to get you thinking about what you might want to do|
|Top 2||Project topic version 2 -- a bit more thought now that you've had more experience with the simulations|
|Prop||Project proposal: 1 page summary of your question of interest and proposed approach to explore this question through simulations|
|Meet||Meeting w/instructor about project -- happens in regular lab meeting times|
|Student Pres||Presentation of project to class -- just 5 minutes and a few slides to convey the key idea, model, and results|
|Paper||Final paper (date pending grades schedule from University)|
In your presentation to the class, you are expected to have substantive, if not final, results to discuss. Presentations should clearly motivate the psychological issue or phenomenon and your approach to it, in addition to a summary of the methods and results.
A final paper describing your project is due on the last day of classes. This paper should be around 5 pages single-spaced (precise page count not important -- just a rough guide -- important thing is addressing all the key elements), and should be in a basic APA-like format, with a concise introduction to the psychological / neural / computational issue or phenomenon and a justification of your general approach to modeling it, methods (how you constructed or modified your model, what manipulations you performed and why), results (what you found in terms of the relevant measures of model function, including averages over multiple runs of the model as they can be somewhat random on any given run), and a concluding discussion (about the significance of your results, what you might do to improve your model, etc.). You do not need to include an abstract. Network diagrams and graphs of significant results should be included. However, do not include excessive or redundant figures; the text should provide a clear interpretation and justification of all figures. NOTE: For each day that the final paper is late, 5% will be deducted from your final paper grade.
Project Topic and Approach Guidelines
Here is some more info about selecting an appropriate project topic and guidelines for how to get started on doing the project.
- The main point of the project is to build a connection between some specific cognitive neuroscience (or other) data, and a computational model thereof -- the goal is for you to learn first-hand how the models help you better understand some specific phenomenon of interest. Thus, you will need to find one or more scientific papers with relevant data to model -- this is a great place to start in thinking about your project topic. Just start typing some terms of interest into http://scholar.google.com and see if you can hit upon a paper with some interesting findings you'd like to model.
- Undergraduates can often start out by just doing some basic manipulations to an existing simulation model from the textbook projects -- for example if you're interested in amnesia, you can damage the hippocampus model in various ways. Drug effects can often be simulated by manipulating various parameters in an existing model, and observing the effects on overall behavior. Again, the key is to make a connection between some specific data and the model -- it is not critical to demonstrate your computer programming skills. However, if you are interested in a topic that is not well covered by the textbook projects, by all means go big and build a new model from scratch -- you will have plenty of help in the lab to do this.
- Grad students are typically expected to produce a more sophisticated model, often of the empirical phenomena you are actually studying in your research.
- For the project proposal and topic emails, please specify a domain as specifically as possible, and do try to use google scholar to find some relevant articles so you can get a clearer idea. If you have any idea about how to actually implement this in a model, please specify. It does not need to be very long -- just include as much specificity as you can.
Productive participation in class discussion is encouraged to help you get the most out of this course. You are expected to read the text chapters the week they are assigned and to come to class prepared to actively participate in discussion. You can also communicate about any course-related topics as a group by emailing firstname.lastname@example.org.
Grads & Undergrads: This course is designed for advanced undergraduates and graduate students. Undergrads need not feel intimidated by the presence of graduate students in the class. More will be expected of the grads than the undergrads, especially when it comes to the final projects. Also, undergrads will be responsible for fewer of the homework questions.
Grades are not curved; they are based on percentages (note: Canvas truncates points, so a 92.9 is still an A- for example):
97-100 A+ 87-89 B+ 77-79 C+ 67-69 D+ 93-96 A 83-86 B 73-76 C 63-66 D 90-92 A- 80-82 B- 70-72 C- 60-62 D-
Note that the University does not give out A+ grades, but I record these internally, e.g., for use in a recommendation letter.
See http://grey.colorado.edu/CompCogNeuro/index.php/CCNBook/Sims/All for the full listing of the simulation projects and associated homework questions, and instructions for getting everything running.
