The what, where, and why of priority maps and their interactions with visual working memory

GJ Zelinsky, JW Bisley - Annals of the new York Academy of …, 2015 - Wiley Online Library
Priority maps are winner‐take‐all neural mechanisms thought to guide the allocation of
covert and overt attention. Here, we go beyond this standard definition and argue that …

Spikes not slots: noise in neural populations limits working memory

PM Bays - Trends in cognitive sciences, 2015 - cell.com
This opinion article argues that noise (randomness) in neural activity is the limiting factor in
visual working memory (WM), determining how accurately we can maintain stable internal …

A category-free neural population supports evolving demands during decision-making

D Raposo, MT Kaufman, AK Churchland - Nature neuroscience, 2014 - nature.com
The posterior parietal cortex (PPC) receives diverse inputs and is involved in a dizzying
array of behaviors. These many behaviors could rely on distinct categories of neurons …

Neural mechanisms of speed-accuracy tradeoff

RP Heitz, JD Schall - Neuron, 2012 - cell.com
Intelligent agents balance speed of responding with accuracy of deciding. Stochastic
accumulator models commonly explain this speed-accuracy tradeoff by strategic adjustment …

[HTML][HTML] Variance as a signature of neural computations during decision making

AK Churchland, R Kiani, R Chaudhuri, XJ Wang… - Neuron, 2011 - cell.com
Traditionally, insights into neural computation have been furnished by averaged firing rates
from many stimulus repetitions or trials. We pursue an analysis of neural response variance …

Attention, learning, and the value of information

J Gottlieb - Neuron, 2012 - cell.com
Despite many studies on selective attention, fundamental questions remain about its nature

Reward value-based gain control: divisive normalization in parietal cortex

K Louie, LE Grattan, PW Glimcher - Journal of Neuroscience, 2011 - Soc Neuroscience
The representation of value is a critical component of decision making. Rational choice
theory assumes that options are assigned absolute values, independent of the value or …

Working memory and decision-making in a frontoparietal circuit model

JD Murray, J Jaramillo, XJ Wang - Journal of Neuroscience, 2017 - Soc Neuroscience
Working memory (WM) and decision-making (DM) are fundamental cognitive functions
involving a distributed interacting network of brain areas, with the posterior parietal cortex …

Reward modulates attention independently of action value in posterior parietal cortex

CJ Peck, DC Jangraw, M Suzuki, R Efem… - Journal of …, 2009 - Soc Neuroscience
While numerous studies have explored the mechanisms of reward-based decisions (the
choice of action based on expected gain), few have asked how reward influences attention …

Reciprocal relations between cognitive neuroscience and formal cognitive models: opposites attract?

BU Forstmann, EJ Wagenmakers, T Eichele… - Trends in cognitive …, 2011 - cell.com
Cognitive neuroscientists study how the brain implements particular cognitive processes
such as perception, learning, and decision-making. Traditional approaches in which …
