In schizophrenia (SZ), a specific binding deficit in working memory (WM) has not yet been demonstrated, given that studies with various methodologies were conducted and the results obtained were heterogeneous. Thus, a meta-analysis of 10 WM studies was performed. Effect sizes were calculated for binding and control conditions. Analyses disclosed significantly lower scores in SZ patients relative to controls for both binding and control conditions. In addition, analyses revealed no greater impairments for the binding condition than for the control condition in SZ patients. Our meta-analysis suggests that there is no specific deficit of binding in WM in SZ.

Dopamine receptor D4 (DRD4) plays a vital role in regulating various physiological functions, including attention, impulse control, and sleep, as well as being associated with various neurological diseases, including attention deficit hyperactivity disorder, novelty seeking, and so on. However, a comprehensive analysis of harmful nonsynonymous single nucleotide polymorphisms (nsSNPs) of the DRD4 gene and their effects remains unexplored. The aim of this study is to uncover novel damaging missense nsSNPs and their structural and functional effects on the DRD4 receptor.

The astroglial glutamate transporter in the hippocampus and anterior cingulate cortex (ACC) is critically involved in chronic pain-induced cognitive and psychiatric abnormalities. We have previously reported that LDN-212320, a glutamate transporter-1 (GLT-1) activator, attenuates complete Freund's adjuvant (CFA)-induced acute and chronic nociceptive pain. However, the cellular and molecular mechanisms underlying GLT-1 modulation in the hippocampus and ACC during chronic pain-induced cognitive deficit-like and anxiety-like behaviors remain unknown.

Mutations in methyl CpG binding protein 2 (MeCP2) are linked to Rett syndrome, in which epilepsy is one of the most well-described disorders. However, little is known about the specific role of MeCP2 during epileptogenesis. Our previous study has demonstrated that MeCP2 has a unique control on the development of mossy fiber sprouting (MFS) in the epileptic hippocampus.

Background: Neuronal structure is disrupted after spinal cord injury (SCI), causing functional impairment. The effectiveness of exercise therapy (ET) in clinical settings for nerve remodeling post-SCI and its underlying mechanisms remain unclear. This study aims to explore the effects and related mechanisms of ET on nerve remodeling in SCI rats.
