What is the Origin of Neural Network Connectivity?

This term is a cornerstone of modern systems neuroscience, derived from the concept of the connectome, which maps all neural connections in the brain. 'Connectivity' is a quantifiable metric that assesses the synchrony of activity between brain regions. Its relevance in hormonal health lies in understanding how endocrine signals influence the structural scaffolding and functional communication across the central nervous system.

What is the Mechanism of Neural Network Connectivity?

Functional connectivity is largely determined by the strength and number of synapses, the integrity of myelin sheaths, and the balance of excitatory and inhibitory neurotransmission. Hormones, particularly sex steroids, exert a profound influence by promoting synaptogenesis and dendritic branching, especially in the hippocampus and cortex. Enhanced connectivity facilitates the brain's ability to rapidly process information, integrate sensory inputs, and execute complex motor and cognitive tasks.

Neural Network Connectivity

Meaning

Neural Network Connectivity refers to the measure of the structural and functional links between distinct regions of the brain, reflecting the efficiency and coherence of information transfer across different neuronal populations. Maintaining robust connectivity is essential for integrated cognitive functions, emotional stability, and the complex regulation of the neuroendocrine system. Age-related hormonal decline often contributes to a measurable decrease in this critical network integrity.
