Stand Density and Initial Spacing,elopment of the nervous system. The primary somatosensory cortex (S1) of rodents offers a unique opportunity to identify key molecules that regulate glutamate-dependent cortical development because of its unique cytoarchitectonic structures in layer 4 termed “barrels”. Analysis of knockout mice hasextract 发表于 2025-3-23 20:28:56
Stand Density and Initial Spacing, While a variety of molecular guidance cues help set up the topographic axonal projections in the brain, activity-dependent interactions between pre- and postsynaptic elements play a key role in neural patterning. Here we review our and other groups’ analyses of the phenotypes of mice with various tacetylcholine 发表于 2025-3-24 01:03:04

https://doi.org/10.1007/978-3-319-01827-0s in the CNS, it seems unlikely that each individual cell’s identity and connectivity is intrinsically or genetically specified. Both neural activity and molecular cues provide possible mechanisms by which network properties of the developing brain can emerge from relative disorder. Emphasizing thebonnet 发表于 2025-3-24 09:28:55

Subcortical and Neocortical Guidance of Area-specific Thalamic Innervation,orrect connections of thalamocortical axons (TCAs) between specific thalamic nuclei and cortical areas. First, the correct area map has to be generated in cortex, and thalamic nuclei need to be specified in correct patterns. Second, axon guidance molecules that are expressed in the TCA subcortical p无关紧要 发表于 2025-3-24 20:25:09
The Earliest Thalamocortical Interactions,ence of external sensory input in an autonomous fashion. This initial map requires no major fiber reorganization between the thalamus and cortex: a simple 90 degree rotation can explain the early topographic relations between thalamic volume and the cortical sheet. However, this initially simple lay责难 发表于 2025-3-25 02:33:18
