Prefrontal FGF1 Signaling is Required for Accumbal Deep Brain Stimulation Treatment of Addiction

open access: yesAdvanced Science, EarlyView.
This research delineates that a cortical‐accumbal pathway and local FGF1 signaling in the medial prefrontal cortex are critical for NAc‐DBS to be effective in altering morphine CPP. These findings demonstrate a top‐down motif to regulate the therapeutic effects of subcortical DBS on addiction and support the potential for addiction treatments involving

Effective temperatures and radii of planet-hosting stars from IR photometry

open access: yes, 2003
In this paper we present and analyse determinations of effective temperatures of planet-hosting stars using infrared (IR) photometry. One of our goals is the comparison with spectroscopic temperatures to evaluate the presence of systematic effects that ...

The Transit Light Curve Project. V. System Parameters and Stellar Rotation Period of HD 189733 [PDF]

open access: yes, 2006
We present photometry of HD 189733 during eight transits of its close-in giant planet, and out-of-transit photometry spanning two years. Using the transit photometry, we determine the stellar and planetary radii and the photometric ephemeris.

Conjugate-plane photometry: reducing scintillation in ground-based photometry [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2010
High precision fast photometry from ground-based observatories is a challenge due to intensity fluctuations (scintillation) produced by the Earth's atmosphere. Here we describe a method to reduce the effects of scintillation by a combination of pupil reconjugation and calibration using a comparison star.

Altered Neural Activity in the Mesoaccumbens Pathway Underlies Impaired Social Reward Processing in Shank3‐Deficient Rats

open access: yesAdvanced Science, EarlyView.
This study examines the effects of Shank3 mutation on the mesoaccumbens pathway using a Shank3‐deficient rat model. The findings reveal altered social reward processing in these rats, accompanied by changes in dopaminergic and GABAergic neural activity within the ventral tegmental area (VTA) and dopamine release in the nucleus accumbense (NAc ...

Regulation of PVT‐CeA Circuit in Deoxynivalenol‐Induced Anorexia and Aversive‐Like Emotions

open access: yesAdvanced Science, EarlyView.
The study investigates Deoxynivalenol (DON) effects on feeding and emotions, focusing on the central amygdala (CeA). Acute DON exposure reduces food intake and alters behavior, linked to CeAGABA neuron activity and PVT‐CeA connectivity. Manipulating CeAGABA neurons and using SCN10A antagonist A‐803467 alleviate DON's effects, offering potential ...

Jitter Across 15 yr: Leveraging Precise Photometry from Kepler and TESS to Extract Exoplanets from Radial Velocity Time Series

open access: yesThe Astronomical Journal
Stellar activity contamination of radial velocity (RV) data is one of the top challenges plaguing the field of extreme-precision RV science. Previous work has shown that photometry can be very effective at removing such signals from RV data, especially ...

Photo‐Biomodulation of the Hippocampus Using Near‐Infrared Laser to Enhance Cognitive Function in Mice

open access: yesAdvanced Science, EarlyView.
Here a transcranial photo‐biomodulation approach is developed using near‐infrared (NIR) laser on hippocampus of mice, revealing significant improvements in learning and memory ability of mice under normal and disease conditions. The improvement results from the high‐density cell‐induced NIR local energy deposition, neuronal activation, and axonogenesis

Unlocking the secrets of stellar haloes using combined star counts and surface photometry

open access: yes, 2012
The stellar haloes of galaxies can currently be studied either through observations of resolved halo stars or through surface photometry. Curiously, the two methods appear to give conflicting results, as a number of surface photometry measurements have ...

PROPER IMAGE SUBTRACTION—OPTIMAL TRANSIENT DETECTION, PHOTOMETRY, AND HYPOTHESIS TESTING [PDF]

open access: yes, 2016
Transient detection and flux measurement via image subtraction stand at the base of time domain astronomy. Due to the varying seeing conditions, the image subtraction process is non-trivial, and existing solutions suffer from a variety of problems ...
