The infant brain will grow 5x in size by adulthood. 2 factors contribute to this: the growth of synaptic connections between neurons, & the myelination of nerve fibers. A decrease in synapses is seen after adolescence (synaptic pruning), & ~50% do not survive until adulthood. Pruning is influenced by environmental factors and is widely thought to represent…

Cells in your brain acting as little micro-gardeners? It's true! A recent article from Fast Company explains “synaptic pruning” as being when the microglial cells in your brain and how they act as gardeners and prune away synaptic connections so there’s room for new ones to form. And the key to proper brain maintenance? Sleep and mindfulness. Read on!
