Approach Motivation and Reward Sensitivity: Effects of High‐Definition Transcranial Direct Current Stimulation (HD‐tDCS) to Brain Hemispheres on Effort‐Related Cardiovascular Response

European Journal of Neuroscience, Volume 63, Issue 3, February 2026.
Brain stimulation over the dorsolateral prefrontal cortex affects effort‐related cardiovascular responses during a mental concentration task of unclear difficulty in presence of moderate incentives. Right cathodal stimulation leads to higher physiological effort compared to left cathodal and sham stimulation.

Neural Dynamics of Social Cognition: A Single‐Trial Computational Analysis of Learning Under Uncertainty

Human Brain Mapping, Volume 47, Issue 1, January 2026.
We apply a hierarchical Bayesian model to single‐trial EEG data from an advice‐taking task, demonstrating that EEG activity closely mirrors the predicted sequence of prediction errors and precision signals. Additionally, source‐localised activity in the fusiform gyrus and posterior cingulate cortex covaried with participants' psychosocial functioning ...

Monolithic Silicon Photonic Transceiver for 160 km Multi‐Channel Quantum Entanglement Distribution in Fiber Network

Laser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
The paper demonstrates a chip scale (4.5 x 4.5 mm2) silicon integrated system that is capable of distributing entangled photons over 160 km single mode fibers without dispersion compensations and external optical filters. The results highlight the potential for massive production and large‐scale deployed quantum integrated circuits for a future ...

Basal Forebrain Volume Predicts Disease Conversion in Prodromal Synucleinopathy

Movement Disorders Clinical Practice, Volume 13, Issue 1, Page 198-207, January 2026.
Abstract Background Isolated rapid eye movement sleep behavior disorder (iRBD) is a prodromal stage of Parkinson's disease (PD) and dementia with Lewy bodies (DLB). The basal forebrain (BF), a key cholinergic structure, is a site of known pathology in later stages of Lewy body disorders.

The Management of Parkinson's Disease Before, during and after Pregnancy—an MDS Scientific Issues Committee Review

Movement Disorders Clinical Practice, Volume 13, Issue 1, Page 44-59, January 2026.
Abstract Background Pregnancy after a Parkinson's diagnosis presents complex challenges. Due to the paucity of literature, there is no evidence‐based guidelines and protocols for preconception care, management of pregnancy, childbirth and the postpartum period in women with early‐onset Parkinson's disease (PD).
