Journal ArticleDOI
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.
Journal ArticleDOI
Neuronal correlates of decision-making in secondary somatosensory cortex
TL;DR: Monkeys trained to compare two mechanical vibrations applied sequentially to the fingertips and to report which of the two had the higher frequency discriminated between two sequential stimuli recorded single neurons in secondary somatosensory cortex while the monkeys performed the task.
Journal ArticleDOI
Sensing without Touching: Psychophysical Performance Based on Cortical Microstimulation
TL;DR: 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.
Journal ArticleDOI
Decoding a perceptual decision process across cortex.

TL;DR: The results suggest that frontal lobe circuits are more engaged in the readout of sensory information from working memory, when it is required to be compared with other sensory inputs, than simply engaged in motor responses during this task.
Journal ArticleDOI
Do Sensory Cortices Process More than One Sensory Modality during Perceptual Judgments
TL;DR: It is suggested that multimodal encoding and perceptual judgments in these tasks occur outside the sensory cortices studied here, and the identity of the stimulus could only be decoded from responses to their principal sensory modality during the stimulation periods and not during the processing steps that link sensation and decision making.
