algorithms), and texture analysis/synthesis. Heeger's current research focuses on developing and testing a unified theory of cortical circuit function. The field of neuroscience needs a general theory of brain function, like Maxwell's Equations for the brain. There is considerable evidence that the brain relies on a set of canonical neural circuits that perform a set of canonical neural computations, repeating them across brain regions and modalities to apply operations of the same form. But we lack a theoretical framework for how such canonical computations can support a wide variety of cognitive processes and brain functions. Heeger developed a class of circuit models, called Oscillatory Recurrent Gated Neural Integrator Circuits (ORGaNICs), that recapitulate many key neurophysiological and cognitive/perceptual phenomena including sensory processing and attention in visual cortex, working memory in prefrontal and parietal cortex, and premotor activity and motor control in motor cortex. The theory offers a unified framework for the dynamics of neural activity, and it recapitulates many key neurophysiological and cognitive/perceptual phenomena (including normalization, oscillatory activity, sustained delay-period activity, sequential activity and traveling waves of activity), measured with a wide range of methodologies (including intracellular recordings of membrane potential fluctuations, firing rates of individual neurons, optogenetic manipulations, local field potentials, neuroimaging, and behavioral performance).
