Super-resolution STED microscopy is demonstrated for the first time in the deeply embedded mouse hippocampus in vivo, revealing direct evidence for an unprecedentedly high level of synapse remodeling in a brain structure closely associated with memory processing.
Social-interaction impairment in germ-free mice is associated with a markedly altered transcriptional response to social novelty in the amygdala, as characterised by replacement of upregulation of common stimulus-induced pathways with upregulation of the splicing machinery.
Unbiased transcriptome analyses reveal that neural progenitor cells downregulate protein biosynthetic machinery during early forebrain development, and this fundamental process matches proteomic changes in the adjacent cerebrospinal fluid and is regulated in part by MYC.
The subjective time of social interactions reflects one's autistic-like tendency and is critically mediated by oxytocin, indicating that time perception is ingrained with personality traits, which likely have neuroendocrine origins as per previous research.
In contrast to amniotes, zebrafish (ray-finned fish, teleost) centra are formed from specialised notochord sheath cells, and the segmental patterning of these cells is independent of the segmentation clock.
Oxytocin, a peptide linked to the processing of socially meaningful stimuli, modulates excitatory synaptic transmission in dopaminergic neurons of ventral tegmental area via retrograde endocannabinoid signaling, acting as a pathway-specific temporal filter for synaptic inputs.
Oligodendrocytes in white matter use Kir4.1 inwardly rectifying potassium channels to prevent extracellular potassium accumulation, enabling neurons to sustain repetitive firing and limiting the initiation of seizures.
