Reppert T, Heitz R, Schall J
Cell Rep
. 2023 Nov;
42(11):113422.
PMID: 37950871
The medial frontal cortex (MFC) plays an important but disputed role in speed-accuracy trade-off (SAT). In samples of neural spiking in the supplementary eye field (SEF) in the MFC simultaneous...

PMID: 29668383
Balancing the speed-accuracy tradeoff (SAT) is necessary for successful behavior. Using a visual search task with interleaved cues emphasizing speed or accuracy, we recently reported diverse contributions of frontal eye...

PMID: 24966810
There are few behavioral effects as ubiquitous as the speed-accuracy tradeoff (SAT). From insects to rodents to primates, the tendency for decision speed to covary with decision accuracy seems an...

Philos Trans R Soc Lond B Biol Sci
. 2013 Sep;
368(1628):20130071.
PMID: 24018731
The stochastic accumulation framework provides a mechanistic, quantitative account of perceptual decision-making and how task performance changes with experimental manipulations. Importantly, it provides an elegant account of the speed-accuracy trade-off...

Neuron
. 2012 Nov;
76(3):616-28.
PMID: 23141072
Intelligent agents balance speed of responding with accuracy of deciding. Stochastic accumulator models commonly explain this speed-accuracy tradeoff by strategic adjustment of response threshold. Several laboratories identify specific neurons in...

J Neurophysiol
. 2012 Sep;
108(10):2737-50.
PMID: 22956785
Discharge rate modulation of frontal eye field (FEF) neurons has been identified with a representation of visual search salience (physical conspicuity and behavioral relevance) and saccade preparation. We tested whether...

J Neurosci
. 2012 Jun;
32(22):7711-22.
PMID: 22649249
Although areas of frontal cortex are thought to be critical for maintaining information in visuospatial working memory, the event-related potential (ERP) index of maintenance is found over posterior cortex in...

Eur J Neurosci
. 2011 Jun;
33(11):1991-2002.
PMID: 21645095
We review a new computational model developed to understand how evidence about stimulus salience in visual search is translated into a saccade command. The model uses the activity of visually...

. 2010 Sep;
117(4):1113-43.
PMID: 20822291
Stochastic accumulator models account for response time in perceptual decision-making tasks by assuming that perceptual evidence accumulates to a threshold. The present investigation mapped the firing rate of frontal eye...
