Self-Supervised Learning of Accelerometer Data Provides New Insights for Sleep and Its Association with Mortality

Self-Supervised Learning of Accelerometer Data Provides New Insights for Sleep and Its Association with Mortality

Insights into the Association Between Sleep and Mortality Revealed by Self-supervised Learning of Wrist-worn Accelerometer Data In modern society, sleep is an essential basic activity for life, and its importance is self-evident. Accurately measuring and classifying sleep/wake states and different sleep stages is crucial for diagnosing sleep disord...

Closed-loop recruitment of striatal interneurons prevents compulsive-like grooming behaviors

Closed-loop recruitment of striatal interneurons prevents compulsive-like grooming behaviors

Obsessive-compulsive behaviors have long been associated with overactivation of the striatum. The GABA-ergic parvalbumin-positive interneurons (PVIs) in the striatum play a crucial role in regulating striatal activity and inhibiting inappropriate motivated behaviors. To investigate the potential role of striatal PVIs in regulating obsessive-compuls...

Cognitive representations of intracranial self-stimulation of midbrain dopamine neurons depend on stimulation frequency

This paper reports a study on the cognitive representation of intracranial self-stimulation (ICSS) of midbrain dopamine neurons. The authors aimed to answer why rats work to obtain ICSS, i.e., how the pulsatile activation of dopamine neurons is represented in the brain. Research Background: The pulsatile activation of dopamine neurons is typically ...

Cortical gene expression architecture links healthy neurodevelopment to the imaging, transcriptomics and genetics of autism and schizophrenia

Linking Healthy Neurodevelopment with Imaging, Transcriptomic, and Genetic Associations in Autism Spectrum Disorder and Schizophrenia: A Study of Cortical Gene Expression Patterns Background: How does the complex anatomy and functional organization of the human brain develop from the expression of more than 20,000 genes? And how does this process g...
