In vivo brain temperature measurement using quantum dot imaging temperature sensors

This study uses quantum dot imaging temperature sensors to measure brain temperature in mice, revealing vascular cooling's role in protecting against heat stress in pathological conditions.

In vivo deep-brain microscopy at submicrometer resolution with refractive index-matched prism interfaces

This paper develops an implantable microprism interface for deep-brain imaging with submicrometer resolution and wide-field two-photon microscopy.

Low-invasive, wide-field, and cellular resolution two-photon imaging of neural population activity in brainstem and nucleus tractus solitarii

The paper develops a two-photon imaging method to study neural activity in the NTS during VNS and hormone exposure, revealing insights into vagus-NTS pathway function.

Activity-dependent organization of prefrontal hub-networks for associative learning and signal transformation

The paper uses computational methods to analyze neural activity in the mouse dmPFC during fear conditioning, revealing learning-dependent changes in network topology and hub formation.
