Project report due by start of class.
|
In this project you will go through the exercise of developing a model to answer a neuroscience question, by replicating and extending a previously-published modeling effort. You will be required to research a problem; define the hypothesis in the context of previous work; download, modify, and interpret an appropriate model; and explain the model findings and what you learned beyond what was presented in the original research.
The choice of problem to model can come from
ModelDB, or you may identify a problem from your own research.

Final report |
Homework assignments will be graded pass/fail. Students are expected
to complete all homework assignments successfully.
Late assignments will be accepted only with prior approval
from the professors.
The mark in the course will be based on successful completion of
the homework, and the result of 3 tests (one following each section
of the course).
Each test will be graded
based on its completeness, clarity, and demonstrated depth of
understanding.
Grades will be assigned as follows:
| 4 |
|
Work and presentation are superior |
| 3 |
|
Work is accurate and its presentation is of high quality |
| 2 |
|
Work is complete, but there are some problems with its presentation or accuracy |
| 1 |
|
Work is incomplete, inaccurate, or its presentation is poor |
| 0 |
|
Work was not submitted |
Final grades in the course will be determined based on the assessment criteria above. There will be no curve. Final grades have the following meanings:
| A+ |
|
Superior performance in all aspects of the course with
work exemplifying the highest quality. |
| A |
|
Superior performance in most aspects of the course; high quality work in the remainder. |
| A- |
|
High quality performance in all or most aspects of the course. |
| B+ |
|
High quality performance in some of the course;
satisfactory performance in the remainder. |
| B |
|
Satisfactory performance in the course. |
| B- |
|
Satisfactory performance in most of the course, with the
remainder being somewhat substandard. |
| C |
|
Evidence of some learning but generally marginal performance. |
In this course students will explore how neurons communicate through electrical
signals, how information transmission between neurons occurs, and how connectivity
between neurons determines activity patterns and results in specialized behavior.
This course uses a hands-on approach to develop and explain concepts from
computational neurophysiology. The course has two goals: to help students
understand how computational models can be used to analyze, explain and predict
the physiological
behavior of neurons and assemblies of neurons; and to provide students with an
opportunity to use current research tools to investigate the concepts underlying
these computational models. The course will include a very brief review of relevant
concepts from cellular neurophysiology (action and membrane potentials,
channels, etc.) and of mathematical concepts needed to understand the material.
Topics to be covered include Hodgkin-Huxley models of simple and complex
morphologies; central pattern generators; models of simple invertebrate circuits;
integrate-and-fire and spike-response neuron models for use in network models;
models of neural development, ocular dominance and orientation columns;
and rate versus spike-timing dependent plasticity.
This course will be of interest to students in engineering and mathematics with an interest in neuronal modeling, as well as to neuroscientists who would like to understand more about the role of computational models in neurophysiology. A solid math background is needed; some programming (in MATLAB) will be required.
