Synaptogenesis is the formation of synapses between neurons in the nervous system. Although it occurs throughout a healthy person's lifespan , an explosion of synapse formation occurs during early brain development , known as exuberant synaptogenesis . [ 1 ]
New computational models have emerged that refine or extend Hebbian learning. For example, some models now account for the precise timing of neural spikes (as in Spike-Timing-Dependent Plasticity), while others have integrated aspects of neuromodulation to account for how neurotransmitters like dopamine affect the strength of synaptic connections.
For example, the hippocampus is believed to be involved in spatial and declarative memory, as well as consolidating short-term into long-term memory. Studies have shown that declarative memories move between the limbic system, deep within the brain, and the outer, cortical regions. These are distinct from the mechanisms of the more primitive ...
For example, stem cells requires the sox2 gene to maintain pluripotency and is used to detect enduring concentrations of stem cells in CNS tissue. The protein nestin is an intermediate filament , which is essential for the radial growth of axons , and is therefore used to detect the formation of new synapses .

"Life's a climb. But the view is great." There are times when things seemingly go to plan, and there are other moments when nothing works out. During those instances, you might feel lost.
For example, in the C. elegans connectome, the total number of synapses increases 5-fold from birth to adulthood, changing both local and global network properties. [59] Other developmental connectomes, such as the muscle connectome, retain some global network properties even though the number of synapses decreases by 10-fold in early postnatal ...
