Strategic allocation of attention reduces temporally predictable stimulus conflict.
(J Cogn Neurosci, 2012-09)
Humans are able to continuously monitor environmental situations and adjust their behavioral strategies to optimize performance. Here we investigate the behavioral and brain adjustments that occur when conflicting stimulus ...
The dynamics of proactive and reactive cognitive control processes in the human brain.
(J Cogn Neurosci, 2014-05)
In this study, we leveraged the high temporal resolution of EEG to examine the neural mechanisms underlying the flexible regulation of cognitive control that unfolds over different timescales. We measured behavioral and ...
Dopamine regulation of human speech and bird song: a critical review.
(Brain Lang, 2012-09)
To understand the neural basis of human speech control, extensive research has been done using a variety of methodologies in a range of experimental models. Nevertheless, several critical questions about learned vocal motor ...
Pinning down response inhibition in the brain--conjunction analyses of the Stop-signal task.
Successful behavior requires a finely-tuned interplay of initiating and inhibiting motor programs to react effectively to constantly changing environmental demands. One particularly useful paradigm for investigating inhibitory ...
Exploring the role of the substantia nigra pars reticulata in eye movements.
Experiments that demonstrated a role for the substantia nigra in eye movements have played an important role in our understanding of the function of the basal ganglia in behavior more broadly. In this review we explore more ...
Shifting attention to neurons.
(Trends Cogn Sci, 2010-09)
Brain evolution by brain pathway duplication.
(Philos Trans R Soc Lond B Biol Sci, 2015-12-19)
Understanding the mechanisms of evolution of brain pathways for complex behaviours is still in its infancy. Making further advances requires a deeper understanding of brain homologies, novelties and analogies. It also requires ...
The evolving capabilities of rhodopsin-based genetically encoded voltage indicators.
(Curr Opin Chem Biol, 2015-08)
Protein engineering over the past four years has made rhodopsin-based genetically encoded voltage indicators a leading candidate to achieve the task of reporting action potentials from a population of genetically targeted ...
Platelet aggregation and mental stress induced myocardial ischemia: Results from the Responses of Myocardial Ischemia to Escitalopram Treatment (REMIT) study.
(Am Heart J, 2015-04)
BACKGROUND: Mental stress-induced myocardial ischemia (MSIMI) is common in patients with ischemic heart disease (IHD) and associated with a poorer cardiovascular prognosis. Platelet hyperactivity is an important factor in ...
The exon junction complex component Magoh controls brain size by regulating neural stem cell division.
(Nat Neurosci, 2010-05)
Brain structure and size require precise division of neural stem cells (NSCs), which self-renew and generate intermediate neural progenitors (INPs) and neurons. The factors that regulate NSCs remain poorly understood, and ...
