Altered habenular and whole brain functional connectivity in early Parkinson’s disease using 7 T MRI

npj Parkinson's Disease
Parkinson’s disease (PD) is traditionally linked to basal ganglia dysfunction, yet evidence highlights broader network disruptions. Habenula, involved in regulating mood, reward, and motor functions, remains underexplored in PD.

Parallel and convergent processing in grid cell, head-direction cell, boundary cell, and place cell networks. [PDF]

, 2013
The brain is able to construct internal representations that correspond to external spatial coordinates. Such brain maps of the external spatial topography may support a number of cognitive functions, including navigation and memory.

Fact learning in complex arithmetic—the role of the angular gyrus revisited [PDF]

Human Brain Mapping, 2016
AbstractIn recent theoretical considerations as well as in neuroimaging findings the left angular gyrus (AG) has been associated with the retrieval of arithmetic facts. This interpretation was corroborated by higher AG activity when processing trained as compared with untrained multiplication problems.

Atomic Layer Deposition in Transistors and Monolithic 3D Integration

Advanced Functional Materials, EarlyView.
Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

Task-load-dependent activation of dopaminergic midbrain areas in the absence of reward [PDF]

, 2011
Dopamine release in cortical and subcortical structures plays a central role in reward-related neural processes. Within this context, dopaminergic inputs are commonly assumed to play an activating role, facilitating behavioral and cognitive operations ...

Design Strategies and Emerging Applications of High‐Performance Flexible Piezoresistive Pressure Sensors

Advanced Functional Materials, EarlyView.
Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks
