Grading
What When How Much
Class Participation throughout 10% of grade
EXERCISES (2) Feb. 24, Mar. 17 35% of grade
MID-TERM EXAM April 5 35% of grade
RESEARCH PROJECT April 28 20% of grade
IMPORTANT NOTE. This course was listed as "Consent of instructor" for registration. Students should have an aptitude with mathematics and/or neuroscience background in order to perform well in the course.
• CLASS PARTICIPATION will involve participating in discussion about the readings available as PDF files for class each week (download from http://courseinfo.bu.edu/courses/04sprgcasps530_a1/ ).
• The EXERCISES will involve running simulations in the CATACOMB simulation package illustrating basic features of neuronal activity, sequence retrieval, and spatial navigation.
• The EXAM will contain questions on the relation between neural network models and real neural systems, and on the basic computations involved in associative memories and self-organization.
• The RESEARCH PROJECT will allow individual research on a particular subject. The nature of the project will depend upon the student’s background. Most students will perform a predefined programming project using the catacomb package. Those with programming experience can do a separate programming project. If necessary, some may perform an extensive literature review instead of programming.
Description
After taking this course, students should be able to demonstrate solid understanding of computational models of neurobiological mechanisms for memory function and spatial navigation, with a particular emphasis on cellular and circuit models of the hippocampus and related cortical structures. Students should master basic neural network models and an example simulation of cortical function.
