Biomimetics and Neurobiology

Neural Bistability and Amplification Mediated by NMDA Receptors: Analysis of Stationary Equations, by Patrick Shoemaker. This paper analyzes the bistable and amplifying states that may be induced in neurons and dendrites by activation of NMDA receptors in combination with other membrane conductances.
Optic Flow Estimation on Trajectories Generated by Bio-Inspired Closed-Loop Flight, by Patrick Shoemaker, Andrew Hyslop, and Sean Humbert. This paper analyzes bio-inspired elementary motion detectors as estimators of optic flow rate and compares them with several numerical algorithms using an information-theoretic metric.
Theta Motion Processing in Fruit Flies, by Jamie Theobald, Patrick Shoemaker, Dario Ringach, and Mark Fry. In this paper, the tracking by fruit flies of visual objects displaying paradoxical motion cues is studied, and it is shown that their responses are consistent with a superposition of two control efforts, one which responds to first-order motion cues, and a second which depends on the position of the higher-order object.
A model for the detection of moving targets in visual clutter inspired by insect physiology,by Steven Wiederman, Patrick Shoemaker, and David O'Carroll. PLoS ONE 3(7): e2784. doi:10.1371/journal.pone.0002784, 2008.
Nonlinear neurons in the early visual ganglia of insects: New results and a computational model, by Patrick Shoemaker, Steven Wiederman, and David O'Carroll. A poster presented at the Inaugural Queensland Brain Institute Mathematical and Computational Neuroscience Workshop, Brisbane, August 2006. (Note page format is nonstandard size.)
Velocity constancy and models for wide-field motion detection in insects, by Patrick Shoemaker, David O'Carroll, and Andrew Straw. Biological Cybernetics, Vol. 93, No. 4, pp. 275-287, 2005.
