Summary
Neurons in the cerebral cortex form structurally integrated clusters, or modules, through directed axonal connections. This self-assembly mechanism allows for the active isolation of these neuronal ensembles into unified systems.
Area of Science:
- Neuroscience
- Cellular Biology
- Neuroanatomy
Background:
- Accumulated data on cerebral cortex cytoarchitectonics suggest neuronal clustering.
- Existing research indicates neurons contribute to these clusters via axonal projections.
Purpose of the Study:
- To elucidate the structural organization of neuronal clusters in the cerebral cortex.
- To understand the role of axonal connections in forming functional neuronal systems.
Main Methods:
- Analysis of cytoarchitectonic data.
- Examination of neuronal projection patterns, including axons of projection, associative, and callosal neurons, and interneurons.
Main Results:
- Neurons structurally combine into compact clusters (ensembles or blocks).
- Axonal collaterals from projection, associative, and callosal neurons, along with interneurons, integrate these ensembles.
- Divergent axonal spread from clusters and reciprocal convergence of surrounding neurons create focal points of axonal terminals, enabling self-assembly.
Conclusions:
- Neuronal clusters represent unified morphofunctional systems within the cerebral cortex.
- The described mechanism facilitates the active isolation and self-assembly of neuronal modules.
