Boosting Skull-Stripping Performance for Pediatric Brain Images [PDF]

open access: yesarXiv
Skull-stripping is the removal of background and non-brain anatomical features from brain images. While many skull-stripping tools exist, few target pediatric populations. With the emergence of multi-institutional pediatric data acquisition efforts to broaden the understanding of perinatal brain development, it is essential to develop robust and well ...

The Cerebrospinal Fluid Secretion Rate Increases in Awake and Freely Moving Rats but Differs With Experimental Methodology

open access: yesAdvanced Science, EarlyView.
CSF dynamics are vital for neurological health. Yet accurate quantification of CSF rates is challenging. Using a novel technique in awake, freely moving rats, significantly higher secretion rates are found than in anesthetized rats. The findings highlight the importance of awake models and the adaptability of methods for studying CSF changes influenced

Effects of skull properties on long-pulsed transcranial focused ultrasound transmission [PDF]

open access: yesarXiv
Transcranial low-intensity focused ultrasound can deliver energy to the brain in a minimally invasive manner for neuromodulation applications. However, continuous sonication through the skull introduces significant wave interactions, complicating precise energy delivery to the target.

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

Massage‐Mimicking Nanosheets Mechanically Reorganize Inter‐organelle Contacts to Restore Mitochondrial Functions in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
Parkinson's disease (PD) progression is aggravated by disrupted inter‐organelle contacts, which are influenced by mechanical forces. NanoMassage, 200 nm PEGylated black phosphorus nanosheets, deliver targeted mechanical stimulation to neural cells.

Neural Patterns of Social Pain in the Brain‐Wide Representations Across Social Contexts

open access: yesAdvanced Science, EarlyView.
Empathy arises from both physiological and social pain, yet their shared and context‐specific neural mechanisms remain unclear. Combining fMRI and multivariate pattern analysis, this study decodes overlapping empathy networks and distinct representations for social exclusion versus separation.
