POST-DOC POSITIONS IN COMPUTATIONAL NEUROSCIENCE
We are developing computational models of primate visual cortex based
on the properties of two-dimensional arrays of interconnected model
neurons and multiple layers of such arrays. These models are
designed to mimic the anatomy and functioning of visual cortex as
closely as practical and to make predictions of observable phenomena
via psychophysical, electrophysiological, and fMRI techniques.
Experiments being planned now will involve the new Berkeley Brain
Imaging Center with its 4-Tesla fMRI system in studying patterns of
cortical excitation resulting from various visual stimuli.
Psychophysical experiments to test our models will continue in our
own laboratory.
Candidates will be expected to perform some combination of analysis,
refinement, and elaboration of these or new, related, computer
models, and participate in design and implementation of
psychophysical and neuroimaging tests of these models. A strong
background in mathematics, physics, or computer science and a
continuing interest in neuroscience are required. Experience with
Matlab, Mathematica, and Linux are desirable as we will shortly
install a Linux-based Beowulf system for large computations in
addition to the computers now in use. A supercomputer at the
Lawrence Berkeley National Laboratory is also available for these
studies.
