Rules from words: a dynamic neural basis for a lawful linguistic process. [PDF]

open access: yesPLoS ONE, 2014
Listeners show a reliable bias towards interpreting speech sounds in a way that conforms to linguistic restrictions (phonotactic constraints) on the permissible patterning of speech sounds in a language.

Attention-dependent modulation of cortical taste circuits revealed by Granger causality with signal-dependent noise. [PDF]

open access: yesPLoS Computational Biology, 2013
We show, for the first time, that in cortical areas, for example the insular, orbitofrontal, and lateral prefrontal cortex, there is signal-dependent noise in the fMRI blood-oxygen level dependent (BOLD) time series, with the variance of the noise ...

Long‐Term Variation in Mesozooplankton Biomass Caused by Top‐Down Effects: A Case Study in the Coastal Sea of Japan

open access: yesGeophysical Research Letters, 2022
Mesozooplankton is a key group for the recruitment of fish and global biogeochemical cycles. Four decadal observations in the coastal Sea of Japan, the marginal sea of the North Pacific, indicate that wet weight‐based mesozooplankton biomass is ...

Neural mechanisms of top-down divided and selective spatial attention in visual and auditory perception

open access: yesBrain Science Advances, 2023
Top-down attention mechanisms require the selection of specific objects or locations; however, the brain mechanism involved when attention is allocated across different modalities is not well understood.

Prefrontal-occipitoparietal coupling underlies late latency human neuronal responses to emotion [PDF]

open access: yes, 2011
Enhanced late positive potentials (LPPs) evoked by highly arousing unpleasant and pleasant stimuli have been consistently observed in event-related potential experiments in humans.

Top-down beta oscillatory signaling conveys behavioral context in early visual cortex

open access: yesScientific Reports, 2018
Top-down modulation of sensory processing is a critical neural mechanism subserving numerous important cognitive roles, one of which may be to inform lower-order sensory systems of the current ‘task at hand’ by conveying behavioral context to these ...

Ants determine their next move at rest: motor planning and causality in complex systems [PDF]

open access: yesRoyal Society Open Science, 2016
To find useful work to do for their colony, individual eusocial animals have to move, somehow staying attentive to relevant social information. Recent research on individual Temnothorax albipennis ants moving inside their colony’s nest found a power-law ...

The conformal window in QCD and supersymmetric QCD [PDF]

open access: yes, 1999
In both QCD and supersymmetric QCD (SQCD) with N_f flavors there are conformal windows where the theory is asymptotically free in the ultraviolet while the infrared physics is governed by a non-trivial fixed-point.

Top-down Control of Visual Alpha Oscillations: Sources of Control Signals and Their Mechanisms of Action

open access: yesFrontiers in Human Neuroscience, 2016
Alpha oscillations (8 to 12 Hz) are thought to inversely correlate with cortical excitability. Goal-oriented modulation of alpha has been studied extensively.

Asset allocation, cross-class correlation and the structure of property returns [PDF]

open access: yes, 1999
Practical applications of portfolio optimisation tend to proceed on a “top down” basis where funds are allocated first at asset class level (between, say, bonds, cash, equities and real estate) and then, progressively, at sub-class level (within property
