The organization of the human cerebral cortex estimated by intrinsic functional connectivity.
Journal of Neurophysiology, 2011 Information processing in the cerebral cortex involves interactions among distributed areas. Anatomical connectivity suggests that certain areas form local hierarchical relations such as within the visual system. Other connectivity patterns, particularly

eLife, 2015 Value-based decisions could rely either on the selection of desired economic goods or on the selection of the actions that will obtain the goods. We investigated this question by recording from the supplementary eye field (SEF) of monkeys during a ...

Examining Representational Similarity in ConvNets and the Primate Visual Cortex [PDF]
arXiv, 2016 We compare several ConvNets with different depth and regularization techniques with multi-unit macaque IT cortex recordings and assess the impact of the same on representational similarity with the primate visual cortex. We find that with increasing depth and validation performance, ConvNet features are closer to cortical IT representations.

Network based statistical analysis detects changes induced by continuous theta-burst stimulation on brain activity at rest [PDF]
, 2014 We combined continuous theta-burst stimulation (cTBS) and resting state (RS)-fMRI approaches to investigate changes in functional connectivity (FC) induced by right dorsolateral prefrontal cortex (DLPFC)-cTBS at rest in a group of healthy subjects.

A large fraction of neocortical myelin ensheathes axons of local inhibitory neurons
eLife, 2016 Myelin is best known for its role in increasing the conduction velocity and metabolic efficiency of long-range excitatory axons. Accordingly, the myelin observed in neocortical gray matter is thought to mostly ensheath excitatory axons connecting to ...

Spatio-Temporal Dynamics of Visual Imagery for Intuitive Brain-Computer Interface [PDF]
arXiv, 2020 Visual imagery is an intuitive brain-computer interface paradigm, referring to the emergence of the visual scene. Despite its convenience, analysis of its intrinsic characteristics is limited. In this study, we demonstrate the effect of time interval and channel selection that affects the decoding performance of the multi-class visual imagery.

Phenomenology without conscious access is a form of consciousness without top-down attention [PDF]
, 2007 We agree with Block's basic hypothesis postulating the existence of phenomenal consciousness without cognitive access. We explain such states in terms of consciousness without top-down, endogenous attention and speculate that their correlates may be a ...
