Single-trial spike trains in parietal cortex reveal discrete steps during decision-making
A better way to explain neuronal activity A brain region called the lateral intraparietal (LIP) area is involved in primate decision-making. The dominant model to explain neuronal firing in LIPExpand

Dissociated functional significance of decision-related activity in the primate dorsal stream
During decision making, neurons in multiple brain regions exhibit responses that are correlated with decisions. However, it remains uncertain whether or not various forms of decision-related activityExpand

V1 is not uniquely identified by polarity reversals of responses to upper and lower visual field stimuli
TLDR
We generated forward models of cortical areas V1, V2 and V3 that were based on realistic estimates of the 3-D shape of these areas and the shape and conductivity of the brain, skull and scalp. Expand

Inferring sparse representations of continuous signals with continuous orthogonal matching pursuit
TLDR
We present a fast method for recovering these identities, amplitudes, and translations of the waveforms that compose the signal and then refining estimates of their amplitudes and translations. Expand

Functional dissection of signal and noise in MT and LIP during decision-making
During perceptual decision-making, responses in the middle temporal (MT) and lateral intraparietal (LIP) areas appear to map onto theoretically defined quantities, with MT representing instantaneousExpand

Gaze and the Control of Foot Placement When Walking in Natural Terrain
SUMMARY Human locomotion through natural environments requires precise coordination between the biomechanics of the bipedal gait cycle and the eye movements that gather the information needed toExpand

Continuous psychophysics: Target-tracking to measure visual sensitivity.
TLDR
We introduce a novel framework for estimating visual sensitivity using a continuous target-tracking task in concert with a dynamic internal model of human visual performance. Expand

The Role of the Lateral Intraparietal Area in (the Study of) Decision Making.
Over the past two decades, neurophysiological responses in the lateral intraparietal area (LIP) have received extensive study for insight into decision making. In a parallel manner, inferredExpand

On determining the intracranial sources of visual evoked potentials from scalp topography: A reply to Kelly et al. (this issue)
TLDR
The cruciform model posits that if a Visual Evoked Potential component originates in cortical area V1, then stimuli placed in the upper versus lower visual field will generate responses with opposite polarity at the scalp. Expand

Response to Comment on “Single-trial spike trains in parietal cortex reveal discrete steps during decision-making”
Shadlen et al.’s Comment focuses on extrapolations of our results that were not implied or asserted in our Report. They discuss alternate analyses of average firing rates in other tasks, theExpand
