Multi-Conjugate Adaptive Optics images of the Trapezium Cluster

, 2007
Multi-Conjugate Adaptive Optics (MCAO) combines the advantages of standard adaptive optics, which provides high contrast and high spatial resolution, and of wide field ~1' imaging. Up to recently, MCAO for astronomy was limited to laboratory experiments.

Quantifying the Contamination from nearby Stellar Companions in Gaia DR3 Photometry

The Astronomical Journal
Identifying and removing binary stars from stellar samples is a crucial but complicated task. Regardless of how carefully a sample is selected, some binaries will remain and complicate interpretation of results, especially via flux contamination of ...

Multifunctional Neural Probes Enable Bidirectional Electrical, Optical, and Chemical Recording and Stimulation In Vivo

Advanced Materials, EarlyView.
Convergence drawing is used to create flexible, microscale, multifunctional fiber‐based neural probes. Optimized materials selection enables individual devices to perform neural recording, electrical stimulation, optogenetics, fiber photometry, fluid delivery, and voltammetric neurotransmitter detection in rodents.

Time‐Dependent Therapeutic Effect of S‐Ketamine on PTSD Mediated by VTA‐OFC Dopaminergic Neurocircuit

Advanced Science, EarlyView.
This study reveals that early rather than late administration of S‐ketamine can ameliorate PTSD symptoms. This phenomenon is attributed to reversing the progressive inhibition of VTADA neurons and the function of VTADA‐OFC circuit following stress. Targeted stimulation of the OFC by TI‐NIBS to enhance DA release effectively extends the therapeutic time
