Domain general mechanisms of perceptual decision making in human cortex.

6 Jul 2009 To successfully interact with objects in the environment, sensory evidence must be continuously acquired, interpreted, and used to guide appropriate motor responses. For example, when driving, a red light should motivate a motor command to depress ...

A neural model of selective attention and object segmentation in the visual scene: an approach based on partial synchronization and star-like architecture of connections.

5 Jul 2009 A brain-inspired computational system is presented that allows sequential selection and processing of objects from a visual scene. The system is comprised of three modules. The selective attention module is designed as a network of spiking neurons ...

Hierarchical coding of characters in the ventral and dorsal visual streams of Chinese language processing.

5 Jul 2009 Functional and spatial hierarchical organization of increasingly language-like word forms has been proposed for alphabetic languages at the occipitotemporal cortex for visual word recognition. In the logographic Chinese language system, similar ...

A self-organizing learning account of number-form synaesthesia.

3 Jul 2009 Some people automatically and involuntarily "see" mental images of numbers in spatial arrays when they think of numbers. This phenomenon, called number forms, shares three key characteristics with the other types of synaesthesia, within-individual ...

Multiple timescales in postural dynamics associated with vision and a secondary task are revealed by wavelet analysis.

2 Jul 2009 Discrete wavelet analysis is used to resolve the center of pressure time series data into several timescale components, providing new insights into postural control. Healthy young and elderly participants stood quietly with their eyes open or closed ...

Linearity of blood-oxygenation-level dependent signal at microvasculature.

2 Jul 2009 The relationship between the blood-oxygenation-level dependent (BOLD) signal and its underlying neuronal activity is still inconclusive. The task of completely understanding this relationship has been encumbered not only by the complexity of ...

Development, validation, and comparison of ICA-based gradient artifact reduction algorithms for simultaneous EEG-spiral in/out and echo-planar fMRI recordings.

2 Jul 2009 EEG data acquired in an MRI scanner are heavily contaminated by gradient artifacts that can significantly compromise signal quality. We developed two new methods based on independent component analysis (ICA) for reducing gradient artifacts from ...

Rhythms of consciousness: binocular rivalry reveals large-scale oscillatory network dynamics mediating visual perception.

Jul 2009 Consciousness has been proposed to emerge from functionally integrated large-scale ensembles of gamma-synchronous neural populations that form and dissolve at a frequency in the theta band. We propose that discrete moments of perceptual experience ...

How barn owls (Tyto alba) visually follow moving voles (Microtus socialis) before attacking them.

Jul 2009 The present study focused on the movements that owls perform before they swoop down on their prey. The working hypothesis was that owl head movements reflect the capacity to efficiently follow visually and auditory a moving prey. To test this ...

Role of layer 6 of V2 visual cortex in object-recognition memory.

Jul 2009 Cellular responses in the V2 secondary visual cortex to simple as well as complex visual stimuli have been well studied. However, the role of area V2 in visual memory remains unexplored. We found that layer 6 neurons of V2 are crucial for the ...
