Sensing without Touching: Psychophysical Performance Based on Cortical Microstimulation
TLDR
The results indicate that microstimulation can be used to elicit a memorizable and discriminable analog range of percepts, and shows that activation of the QA circuit of S1 is sufficient to initiate all subsequent neural processes associated with flutter discrimination.About:

The Neural Basis of Decision Making
TL;DR: This work focuses on simple decisions that can be studied in the laboratory but emphasize general principles likely to extend to other settings, including deliberation and commitment.

Neural Basis of a Perceptual Decision in the Parietal Cortex (Area LIP) of the Rhesus Monkey
TL;DR: In this article, the posterior parietal cortex (area LIP) of two rhesus monkeys were recorded while they discriminated the direction of motion in random-dot visual stimuli and reported their direction judgment by making an eye movement to the appropriate target.
Journal ArticleDOI
Brain–machine interfaces: past, present and future
TL;DR: This paper discusses designing a fully implantable biocompatible recording device, further developing real-time computational algorithms, introducing a method for providing the brain with sensory feedback from the actuators, and designing and building artificial prostheses that can be controlled directly by brain-derived signals.
Journal ArticleDOI
Neural computations that underlie decisions about sensory stimuli
TL;DR: This work proposes neural computations that can account for the formation of categorical decisions about sensory stimuli by accumulating information over time into a single quantity: the logarithm of the likelihood ratio favoring one alternative over another.
Journal ArticleDOI
The neural systems that mediate human perceptual decision making.
TL;DR: Findings from human neuroimaging studies in conjunction with data analysis methods that can directly link decisions and signals in the human brain on a trial-by-trial basis are reviewed to lead to a new view about the neural basis of human perceptual decision-making processes.

Nonparametric statistics for the behavioral sciences
TL;DR: This is the revision of the classic text in the field, adding two new chapters and thoroughly updating all others as discussed by the authors, and the original structure is retained, and the book continues to serve as a combined text/reference.

TL;DR: The fourth edition of The Cognitive Neurosciences continues to chart new directions in the study of the biologic underpinnings of complex cognition -the relationship between the structural and physiological mechanisms of the nervous system and the psychological reality of the mind as discussed by the authors.

Modality and topographic properties of single neurons of cat's somatic sensory cortex.
TL;DR: Observations upon the modality and topographical attributes of single neurons of the first somatic sensory area of the cat’s cerebral cortex, the analogue of the cortex of the postcentral gyrus in the primate brain, support an hypothesis of the functional organization of this cortical area.
Journal ArticleDOI
Cortical microstimulation influences perceptual judgements of motion direction
TL;DR: It is shown that physiological properties measured at the neuronal level can be causally related to a specific aspect of perceptual performance, and specifically to the direction of motion encoded by stimulated neurons.

Neuronal correlates of parametric working memory in the prefrontal cortex
TL;DR: It is predicted that other behavioural tasks that require ordinal comparisons between scalar analogue stimuli would give rise to monotonic responses similar to those reported here.
