Looking for a paper suggestion
I was hoping the readers of Brains could help me out with a paper suggestion: I am
looking for a paper that would be a good example of a study from computational
neuroscience and/or computer modeling in cognitive science. Something that shows
the basics of the approach— and, preferably, something I can give to advanced
undergrads. Under 20 pages long would be ideal. Any ideas?
If you don't want it too techy, I think an excerpt either from Thagard's Computational Philosophy of Science or Churchland's The Engine of Reason, the Seat of the Soul - those are fun.

Several of Richard FitzHugh's early papers from the 60s do a good job of explaining the Hodgkin-Huxley model and his simplification of it, both of which are still relevant to computational neuroscience. They've got some math, but they're easier to get through than many others, and they're the right length:

For psychology, I would choose Philip Johnson-Laird's "Comprehension as the Construction of Mental Models" in Philosophical Transactions of the Royal Society of London, Series B, Biological Sciences, Vol. 295, No. 1077, pp. 353-374.

There is little question that Hodgkin and Huxley provide the most important class of models, and the biggest success story of computational neuroscience. This is because the models have been grounded in cellular biophysics, are the basis for "biologically realistic" network-level models, and pretty much establishes how we (neuroscientists) think about single neurons from a computational perspective.
Given that, I would just have them read one of their original papers, or probably a good summary. I prefer this to the Fitzhugh-Nagumo. The latter is cool, but assumes familiarity with HH, and pretty much is cool because it is able to describe the essential HH dynamics with fewer differential equations. It is hard to appreciate it without an appreciation of HH.
If all the HH articles are too hard and too long for undergrads, I'd just pick the relevant chapter out of any neuroscience textbook such as Kandel and Schwartz, or Zigmond and Bloom, or Purves et al.. The latter is particularly good for undergrads. Any general neuro text will give a good overview of what HH did.
On the other hand, for theoretical psychology with a neuronal taste, you could go for the artificial neural network models like the connectionists of yore. These have not been very helpful in neuroscience, but they have been very helpful in psychology. In that case, I'd consider something from Paul Churchland as it doesn't require all the math but expresses things clearly. Or Jeff Elman's work, like Finding Structure in Time is great.

Technically, only the fifth HH article above is really "computational". It presents the model to capture the data from the first four papers.
Jeez, I sure would like to have a year like their 1952.

All the above suggestions are great. If your aim is to get students to appreciate the role of mathematical modeling and computer simulation in neuroscience then, of course, the H-H model is seminal. However, for a importantly different kind of contribution to computational neuroscience I'd recommend something like the following:
Zipser D, Andersen RA.
A back-propagation programmed network that simulates response properties of a subset of posterior parietal neurons.
Nature. 1988 Feb 25;331(6158):679-84.
http://www.ncbi.nlm.nih.gov/pubmed/3344044
This study is classic because it was among the first to use neural network modeling to support a view about the computations parietal cortex performs.

All great suggestions-- thanks! These were also great memory jogs for me, reminding me of papers I had read long ago or had somehow neglected to read long ago...
We should do this more often on Brains!

The first three chapters of Jeffrey Hawkins' *On Intelligence* - it is longer than 20 pages but,since he's not a philosopher, it is not dense or inaccessible
