The right posterior parietal cortex mediates spatial reorienting of attentional choice bias

A Sengupta, S Banerjee, S Ganesh, S Grover… - Nature …, 2024 - nature.com
Attention facilitates behavior by enhancing perceptual sensitivity (sensory processing) and
choice bias (decisional weighting) for attended information. Whether distinct neural …

Tracking momentary fluctuations in human attention with a cognitive brain-machine interface

AM Chinchani, S Paliwal, S Ganesh… - Communications …, 2022 - nature.com
Selective attention produces systematic effects on neural states. It is unclear whether,
conversely, momentary fluctuations in neural states have behavioral significance for …

Subcortical connectivity correlates selectively with attention's effects on spatial choice bias

V Sreenivasan, D Sridharan - Proceedings of the National Academy of …, 2019 - pnas.org
Neural mechanisms of attention are extensively studied in the neocortex; comparatively little
is known about how subcortical regions contribute to attention. The superior colliculus (SC) …

Presaccadic attention does not facilitate the detection of changes in the visual field

P Gupta, D Sridharan - PLoS Biology, 2024 - journals.plos.org
Planning a rapid eye movement (saccade) changes how we perceive our visual world. Even
before we move the eyes visual discrimination sensitivity improves at the impending target of …

Dissociable components of attention exhibit distinct neuronal signatures in primate visual cortex

AN Chandrasekaran, A Vermani, P Gupta… - Science …, 2024 - science.org
Attention can be deployed in multiple forms and facilitates behavior by influencing
perceptual sensitivity and choice bias. Attention is also associated with a myriad of changes …

Dissociable sensitivity and bias mechanisms mediate behavioral effects of exogenous attention

V Sagar, R Sengupta, D Sridharan - Scientific reports, 2019 - nature.com
Attention can be directed endogenously, based on task-relevant goals, or captured
exogenously, by salient stimuli. While recent studies have shown that endogenous attention …

Dissociation of attentional state and behavioral outcome using local field potentials

SS Prakash, JP Mayo, S Ray - eneuro, 2024 - eneuro.org
Successful behavior depends on the attentional state and other factors related to decision-
making, which may modulate neuronal activity differently. Here, we investigated whether …

Change point detection with multiple alternatives reveals parallel evaluation of the same stream of evidence along distinct timescales

A Booras, T Stevenson, CN McCormack, ME Rhoads… - Scientific reports, 2021 - nature.com
In order to behave appropriately in a rapidly changing world, individuals must be able to
detect when changes occur in that environment. However, at any given moment, there are a …

Neural mechanisms of attention, not expectation, govern spatial selection by probabilistic cueing

S Sunder, K Rajendran, M Biswas, D Sridharan - bioRxiv, 2024 - biorxiv.org
Spatial probabilistic “Posner” cueing is widely employed in studies of endogenous spatial
attention. Such cueing guides attention by providing prior knowledge about the likely spatial …
