We must focus on creative learning dispositions early, during the brain's most active period
of synaptic growth.

They found that exercise may help cognition by increasing blood and oxygen to the brain, increasing levels
of norepinephrine, and endorphins to decrease stress and improve mood, and increasing
growth factors that help create new nerve cells and support
synaptic plasticity.
Repeated applications
of serotonin, a facilitating transmitter important in behavioral dishabituation and sensitization, produced
growth of the sensory neurons that paralleled the long - term enhancement
of synaptic strength.
This finding is in accordance with earlier animal model studies, which have shown that physical activity increases the amount
of growth factors in the brain and improves
synaptic plasticity.
«The new
growth rule provides structural plasticity with a principle that is almost as simple as that
of synaptic plasticity,» says co-author Arjen van Ooyen, who has been working on models for the development
of neural networks for decades.
In the realm
of pure research, we are steadily gaining a better understanding
of how galaxies form; how a single fertilized egg turns into a fruit fly or a congressman; how
synaptic growth supports long - term memory.
The long - term facilitation
of synaptic efficacy that is induced by serotonin in dissociated cell cultures
of sensory and motor neurons
of Aplysia is accompanied by the
growth of new
synaptic connections.
When the synapse
growth is based on the correlated development
of all
synaptic components, it can remain stable for long periods
of time.

These neurotrophic factors stimulate the differentiation,
growth and maintenance
of developing neurons in addition to the survival
of mature neurons, and are key players in
synaptic plasticity [55, 56], cognition and memory formation [57 — 62].
The freezing process is far too slow to stop such dynamic processes as action potentials and
synaptic transmission; short - term memory, however, is suspected to involve chemical modification
of the neurons, and long - term memory is believed to involve the
growth and modification
of neuronal structures, particularly synapses (15).
By affecting the rate
of cell differentiation and gene expression, thyroid hormones regulate the
growth and migration
of neurons, including
synaptic development and myelin formation in specific brain regions.
Growth of the
synaptic web is utterly different from concrete physical things which maintain cells» metabolism and alters their structural and functional energetic state.
Increased perfusion to brain tissue, decreased body weight, upregulation
of growth factors and improved
synaptic plasticity may all be molecular mechanisms underlying the benefits
of enrichment and activity therapies.
