How laminar frontal cortex and basal ganglia circuits interact to control planned and reactive saccades (2005)
Categories Topics: Biological Learning,
Author(s) Brown, J.W. | Bullock, D. | Grossberg, S. |
Abstract How does the brain learn to balance between reactive and planned behaviors? The basal ganglia (BG) and frontal cortex together allow animals to learn planned behaviors that acquire rewards when prepotent reactive behaviors ...

The watercolor illusion and neon color spreading: A unified analysis of new cases and neural mechanisms (2005)
Categories Topics: Biological Vision, Models: Boundary Contour System,
Author(s) Grossberg, S. | Pinna, B. |
Abstract Coloration and figural properties of neon color spreading and the watercolor illusion are studied using phenomenal and psychophysical observations. Coloration properties of both effects can be reduced to a common limiting ...

Laminar cortical dynamics of 3D surface perception: Stratification, transparency, and neon color spreading (2005)
Categories Topics: Biological Learning, Models: Modified ART,
Author(s) Grossberg, S. | Yazdanbakhsh, A. |
Abstract The 3D LAMINART neural model is developed to explain how the visual cortex gives rise to 3D percepts of stratification, transparency, and neon color spreading in response to 2D pictures and 3D scenes. Such percepts are ...

Linking attention to learning, expectation, competition, and consciousness (2005)
Categories Topics: Biological Learning,
Author(s) Grossberg, S. |
Abstract The concept of attention has been used in many senses, often without clarifying how or why attention works as it does. Attention, like consciousness, is often described in a disembodied way. The present article summarizes ...

A laminar cortical model of stereopsis and 3D surface perception: Closure and da Vinci stereopsis (2005)
Categories Topics: Biological Vision,
Author(s) Cao, Y. | Grossberg, S. |
Abstract A laminar cortical model of stereopsis and 3D surface perception is developed and simulated. The model describes how monocular and binocular oriented filtering interact with later stages of 3D boundary formation and surface ...

A model of STDP based on spatially and temporally local information: Derivation and combination with gated decay (2005)
Categories
Author(s) Gorchetchnikov, A. | Hasselmo, M. | Versace, M. |
Abstract Temporal relationships between neuronal firing and plasticity have received significant attention in recent decades. Neurophysiological studies have shown the phenomenon of spike-timing-dependent plasticity (STDP). Various ...

CEDI:  A neural model of colour vision, with applications to image processing and classification (2005)
Categories Topics: Biological Vision, Image Analysis, Models: Other,
Author(s) Carpenter, G.A. | Chelian, S.F. |
Abstract The CEDI (Contrast Enhance / Discount the Illuminant) system models a cascade of primate color vision cells: retinal ganglion, thalamic single opponent, and two types of cortical double opponents (Figure 1). A unified model ...

Self-organizing hierarchical knowledge discovery by an ARTMAP information fusion system (2005)
Categories Topics: Image Analysis, Machine Learning, Applications: Information Fusion, Models: ARTMAP,
Author(s) Carpenter, G.A. | Martens, S. |
Abstract Classifying terrain or objects may require the resolution of conflicting information from sensors working at different times, locations, and scales, and from users with different goals and situations. Current fusion methods ...

Brain categorization:  learning, attention, and consciousness (2005)
Categories Topics: Biological Learning, Models: Distributed ART,
Author(s) Carpenter, G.A. | Ersoy, B. | Grossberg, S. |
Abstract How do humans and animals learn to recognize objects and events? Two classical views are that exemplars or prototypes are learned. A hybrid view is that a mixture, called rule-plus-exceptions, is learned. None of these ...

How the Brain Sees:  Fundamentals and Recent Progress in Modeling Vision (2005)
Categories Topics: Biological Vision, Image Analysis, Models: Boundary Contour System,
Author(s) Grossberg, S. | Mingolla, E. |
Abstract This is a review of neural network based vision modeling techniques. The models discussed are: shunting and distance-dependent networks, boundary grouping and completion models, neon color spreading models, etc. ...
