Ready ... Go: Amplitude of the fMRI Signal Encodes Expectation of Cue Arrival Time [PDF]

, 2009
What happens when the brain awaits a signal of uncertain arrival time, as when a sprinter waits for the starting pistol? And what happens just after the starting pistol fires? Using functional magnetic resonance imaging (fMRI), we have discovered a novel

Brain Responses to Smoking Cues Differ Based on Nicotine Metabolism Rate [PDF]

Biological Psychiatry, 2016
Inherited differences in the rate of metabolism of nicotine, the addictive chemical in tobacco, affect smoking behavior and quitting success. The nicotine metabolite ratio (3'-hydroxycotinine/cotinine) is a reliable measure of nicotine clearance and a well-validated predictive biomarker of response to pharmacotherapy.

Human sensitivity to differences in the rate of auditory cue change [PDF]

The Journal of the Acoustical Society of America, 2013
Measurement of sensitivity to differences in the rate of change of auditory signal parameters is complicated by confounds among duration, extent, and velocity of the changing signal. Dooley and Moore [(1988) J. Acoust. Soc. Am. 84(4), 1332–1337] proposed a method for measuring sensitivity to rate of change using a duration discrimination task.

Spatial and Temporal Patterns of Carbon and Water Use Efficiency on the Loess Plateau and Their Influencing Factors

Land, 2022
Quantitative assessment of the dynamics of carbon and water use efficiency on the Loess Plateau in the context of complex climate change and its driving mechanisms is important for the improvement of the regional ecological environment and the ...

Focusing and orienting spatial attention differently modulate crowding in central and peripheral vision [PDF]

, 2018
The allocation of attentional resources to a particular location or object in space involves two distinct processes: an orienting process and a focusing process.

Heart rate variability as an index of cue reactivity in alcoholics [PDF]

Biological Psychiatry, 1998
Autonomic responses follow exposure to conditioned stimuli such as contextual factors associated with alcohol ingestion. Heart rate variability is under autonomic control and may be a measure of such response.Twenty alcoholics and 23 matched social drinkers (all male) were exposed to a neutral cue and then an alcohol cue in identical settings, during ...

Twelve years of fin whale song evolution in the central North Pacific

Frontiers in Marine Science
Fin whale song consists of low frequency notes arranged in regular, repeating patterns of note type pairings and inter-note intervals (INIs). In the central North Pacific, fin whales use two downswept note types (A and B notes) with both singlet and ...

Using Virtual Reality to Induce and Assess Objective Correlates of Nicotine Craving: Paradigm Development Study

JMIR Serious Games, 2022
BackgroundCraving is a clinically important phenotype for the development and maintenance of nicotine addiction. Virtual reality (VR) paradigms are successful in eliciting cue-induced subjective craving and may even elicit ...

Spatial audio in small display screen devices [PDF]

, 2000
Our work addresses the problem of (visual) clutter in mobile device interfaces. The solution we propose involves the translation of technique-from the graphical to the audio domain-for expliting space in information representation.

A decade of change and stability for fin whale song in the North Atlantic

Frontiers in Marine Science
Fin whale song is a ubiquitous low-frequency pulsing that has been recorded in every ocean basin. In recent years, the complexity of fin whale song has been realized.
