Auditory and multisensory responses in the tectofugal pathway of the barn owl.
27 Jul 2009 
A common visual pathway in all amniotes is the tectofugal pathway connecting the optic tectum with the forebrain. The tectofugal pathway has been suggested to be involved in tasks such as orienting and attention, tasks that may benefit from ...

A microsaccadic rhythm modulates gamma-band synchronization and behavior.
27 Jul 2009 Rhythms occur both in neuronal activity and in behavior. Behavioral rhythms abound at frequencies at or below 10 Hz. Neuronal rhythms cover a very wide frequency range, and the phase of neuronal low-frequency rhythms often rhythmically modulates the ...

N200-speller using motion-onset visual response.
26 Jul 2009 OBJECTIVE: This study presents a brain-computer interface (BCI) named N200-speller. A matrix of motion stimuli are displayed for inducing the motion-onset visual response that allows the subject to spell out a message by scalp EEG. METHODS: The ...

[Neuronal coding of spatial visual information]
24 Jul 2009 The main differences between the geniculate and the ascending tectal/extrageniculate visual systems are the presence of multisensory units and the absence of the strict retinotopical organization in the tectal system. AIM: To investigate the coding ...

22 Jul 2009 This paper describes CAVIAR, a massively parallel hardware implementation of a spike-based sensing-processing-learning-actuating system inspired by the physiology of the nervous system. CAVIAR uses the asychronous address-event representation (AER) ...

Can chimpanzees (Pan troglodytes) discriminate appearance from reality?
22 Jul 2009 A milestone in human development is coming to recognize that how something looks is not necessarily how it is. We tested appearance-reality understanding in chimpanzees (Pan troglodytes) with a task requiring them to choose between a small grape and ...

21 Jul 2009 Visual orientation cues largely determine our perceptions of "vertical," as illustrated in the Rod and Frame Illusion (RFI): an upright rod appears slanted in the opposite direction of a surrounding tilted frame. We used event-related potentials ...

21 Jul 2009 It has been consistently shown that ecstasy users display impairments in learning and memory performance. In addition, working memory processing in ecstasy users has been shown to be associated with neural alterations in hippocampal and/or cortical ...

Spatiotemporal convergence of semantic processing in reading and speech perception.
20 Jul 2009 Retrieval of word meaning from the semantic system and its integration with context are often assumed to be shared by spoken and written words. How is modality-independent semantic processing manifested in the brain, spatially and temporally? ...

"Vague-to-crisp" neural mechanism of perception.
19 Jul 2009 This brief describes neural modeling fields (NMFs) for object perception, a bio-inspired paradigm. We discuss previous difficulties in object perception algorithms encountered since the 1950s, and describe how NMF overcomes these difficulties. NMF ...
