Cortical and hippocampal correlates of deliberation during model-based decisions for rewards in humans.

How do we use our memories of the past to guide decisions we've never had to make before? Although extensive work describes how the brain learns to re...

Cortical Components of Reaction-Time during Perceptual Decisions in Humans.
The mechanisms of perceptual decision-making are frequently studied through measurements of reaction time (RT). Classical sequential-sampling models (SSMs) of decision-making posit RT as the sum of non-overlapping sensory, evidence accumulation, and

How humans react to changing rewards during visual foraging.
Much is known about the speed and accuracy of search in single-target search tasks, but less attention has been devoted to understanding search in multiple-target foraging tasks. These tasks raise and answer important questions about how individuals

Cortical information flow during flexible sensorimotor decisions.
During flexible behavior, multiple brain regions encode sensory inputs, the current task, and choices. It remains unclear how these signals evolve. We simultaneously recorded neuronal activity from six cortical regions [middle temporal area (MT), vis

Trust in deliberation: The consequences of deliberative decision strategies for medical decisions.
Decision aids (DAs) play an increasingly critical role in supporting patients in making preference-sensitive treatment decisions. One largely untested assumption of DA design is that patients should be encouraged to deliberate carefully about their o

Intracranial cortical responses during visual-tactile integration in humans.
Sensory integration of touch and sight is crucial to perceiving and navigating the environment. While recent evidence from other sensory modality combinations suggests that low-level sensory areas integrate multisensory information at early processin

Reminders of past choices bias decisions for reward in humans.
We provide evidence that decisions are made by consulting memories for individual past experiences, and that this process can be biased in favour of past choices using incidental reminders. First, in a standard rewarded choice task, we show that a mo

Spontaneous fast gamma activity in the septal hippocampal region correlates with spatial learning in humans.
Hippocampal neuronal populations exhibit multiple kinds of activity patterns, from the dominant theta rhythm during active exploration to high-frequency ripple-like activity during periods of relative inactivity. In animals, evidence is rapidly accru

Do humans make good decisions?
Human performance on perceptual classification tasks approaches that of an ideal observer, but economic decisions are often inconsistent and intransitive, with preferences reversing according to the local context. We discuss the view that suboptimal

Nicotine Acutely Enhances Reinforcement from Non-Drug Rewards in Humans.
Preclinical research documents that, aside from the primary and secondary reinforcing effects of nicotine intake itself, nicotine also acutely enhances the reinforcing efficacy of non-drug reinforcers ("rewards"). Study of these effects in humans has

Activities of visual cortical and hippocampal neurons co-fluctuate in freely moving rats during spatial behavior.
Visual cues exert a powerful control over hippocampal place cell activities that encode external spaces. The functional interaction of visual cortical neurons and hippocampal place cells during spatial navigation behavior has yet to be elucidated. He
