Innate network mechanisms of temporal pole for semantic cognition in neonatal and adult twin studies [PDF]
Nature CommunicationsWhat are the innate neural mechanisms scaffolding the protracted development of sophisticated human cognition observable later in life? We investigate this question by focusing on the putative hub of the human semantic memory system—the temporal pole ...

Macroscale brain states support the control of semantic cognition [PDF]
Communications BiologyA crucial aim in neuroscience is to understand how the human brain adapts to varying cognitive demands. This study investigates network reconfiguration during controlled semantic retrieval in differing contexts. We analyze brain responses to two semantic

Frontiers in Computational Neuroscience, 2021 Humans quickly and accurately learn new visual concepts from sparse data, sometimes just a single example. The impressive performance of artificial neural networks which hierarchically pool afferents across scales and positions suggests that the ...

Research on Discrete Semantics in Continuous Hand Joint Movement Based on Perception and Expression
Sensors, 2021 Continuous movements of the hand contain discrete expressions of meaning, forming a variety of semantic gestures. For example, it is generally considered that the bending of the finger includes three semantic states of bending, half bending, and ...

Semantic Recollection in Parkinson’s Disease: Functional Reconfiguration and MAPT Variants
Frontiers in Aging Neuroscience, 2021 Decline in semantic cognition in early stages of Parkinson’s disease (PD) is a leading risk factor for future dementia, yet the underlying neural mechanisms are not understood.

Poor physical fitness is associated with impaired memory, executive function, and depression in institutionalized older adults: a cross-sectional study [PDF]
Brazilian Journal of Psychiatry, 2021 Objective: To analyze the association between physical fitness, cognitive function, and depressive symptoms among older adults in long-term care facilities (LTCFs). Methods: Seventy-six institutionalized male and female elderly individuals (65 years and

Flexing the principal gradient of the cerebral cortex to suit changing semantic task demands
eLife, 2022 Understanding how thought emerges from the topographical structure of the cerebral cortex is a primary goal of cognitive neuroscience. Recent work has revealed a principal gradient of intrinsic connectivity capturing the separation of sensory-motor ...

What Do We Mean by Behavioral Disinhibition in Frontotemporal Dementia?
Frontiers in Neurology, 2021 Behavioral variant frontotemporal dementia, unlike other forms of dementia, is primarily characterized by changes in behavior, personality, and language, with disinhibition being one of its core symptoms.

The neural correlates of semantic control revisited
NeuroImage, 2021 Semantic control, the ability to selectively access and manipulate meaningful information on the basis of context demands, is a critical component of semantic cognition.
