The mechanisms underlying development processes and functional dynamics of neural circuits are far from understood. Long non-coding RNAs (lncRNAs) have emerged as essential players in defining identities of neural cells, and in modulating neural activities. In this review, we summarized latest advances concerning roles and mechanisms of lncRNAs in assembly, maintenance and plasticity of neural circuitry, as well as lncRNAs' implications in neurological disorders. We also discussed technical advances and challenges in studying functions and mechanisms of lncRNAs in neural circuitry. Finally, we proposed that lncRNA studies would advance our understanding on how neural circuits develop and function in physiology and disease conditions.

Recent breakthroughs in tumor biology have redefined the tumor microenvironment as a dynamic ecosystem in which the nervous system has emerged as a pivotal regulator of oncogenesis. In addition to their classical developmental roles, neural‒tumor interactions orchestrate a sophisticated network that drives cancer initiation, stemness maintenance, metabolic reprogramming, and therapeutic evasion. This crosstalk operates through multimodal mechanisms, including paracrine signaling, electrophysiological interactions, and structural innervation guided by axon-derived guidance molecules.

Primate lateral intraparietal area (LIP) has been directly linked to perceptual categorization and decision-making. However, the intrinsic LIP circuitry that gives rise to the flexible generation of motor responses to sensory instruction remains unclear. Using retrograde tracers, we delineate two distinct operational compartments based on different intrinsic connectivity patterns of dorsal and ventral LIP.

Pelvic visceromotor functions such as micturition are regulated by coordinated autonomic and somatic motor pathways from the central nervous system. The parasympathetic system induces detrusor muscle contraction while the somatic system facilitates relaxation of the external urethral sphincter, ensuring synchronized and efficient bladder emptying during the voiding process. This study explores the relationship between Barrington's nucleus corticotropin-releasing hormone (CRH)-ergic projections and the formation of perineural nets (PNNs) among spinal motoneurons, particularly parasympathetic preganglionic neurons in the intermediolateral nucleus (IML) and Onuf's nucleus during the maturation of the neural circuitry controlling pelvic visceromotor functions.

The Anatolian ground squirrel (Spermophilus xanthoprymnus) offers a valuable model for investigating neuroadaptive processes in the retina during hibernation. This study aimed to assess the expression of vesicular glutamate transporter 1 (VGLUT1), glutamic acid decarboxylase (GAD) isoforms GAD65 and GAD67, and microtubule-associated protein 2 (MAP2) in the retina during pre-hibernation and hibernation states. Retinal tissues were analyzed using immunohistochemistry and densitometric quantification.

Psychotic-like experiences (PLEs) -subclinical experiences or symptoms that resemble psychosis, such as hallucinations and delusional thoughts-often emerge during adolescence and are predictive of serious psychopathology. Understanding PLEs during adolescence is crucial due to co-occurring developmental changes in neural reward systems that heighten the risk for psychotic-related and affective psychopathology, especially in those with a family history of severe mental illness (SMI). We examined associations among PLEs, clinical symptoms, and neural reward function during this critical developmental period.
