what’s it and why is it so vital?

We breathe, walk, work, play with our children, think up recipes, and carry them out. These are only a few of the activities we’re capable of perform in our day by day lives, without asking ourselves what’s behind all of it and what makes them possible. The reply lies in synaptic pruning.

This feat of engineering works through the destruction of neurons. Destroying in an effort to construct and strengthen? Paradoxically, yes. Let’s see what it’s and why it’s so vital.

What’s synaptic pruning?

To grasp what synaptic pruning is, let’s first take a have a look at what neurons are and the way they function. A neuron is known as a highly specialized kind of nerve cell, which has the function of receiving, processing, and sending information through electrical and chemical impulses.

Neurons are message carriers. And that’s where the next concept takes place: the synapse.

Synapse refers to a brain strategy of contact between neurons. The sending cell sends or produces neurotransmitters which can be deposited within the synaptic space and are available into contact with the receiving neuron, which reacts by either exciting or inhibiting its response.

Put more simply, synapsis is neuronal communication. Now, synaptic pruning is a process during which there’s a removal of synaptic connections that we aren’t using and don’t need.

This frees up the brain and helps it to be more efficient. It occurs in childhood, but especially in adolescence.

It is because we’re born with quite a few neural connections, that are much higher in the primary years of life in comparison with maturity. Nonetheless, the brain must perfect its development and functioning.

Stages of synaptic pruning

Neuronal pruning takes place in numerous stages:

• From the embryonic stage and as much as 2 years of life there’s a proliferation of neurons and connections. This enables the brain to adapt to the context and learn.
• From the age of three, synaptic pruning begins, which reorganizes the brain, strengthening those connections which can be used and essential, while eliminating people who aren’t.

Importance of synaptic pruning

As we’ve already identified, this neuronal destruction is positive and essential, because it allows the brain to operate higher. Nonetheless, like a clockwork machine, the brain needs all these processes to occur in the best measure. When this isn’t the case, disorders occur. For instance, excessive neuronal pruning is related to schizophrenia.

Nonetheless, synaptic pruning doesn’t occur in the identical way in all brain structures. Within the prefrontal cortex, the creation of synapses continues until concerning the age of 20.

This cortex is answerable for executive functions (corresponding to planning and decision-making) and for self-regulation and impulse control. Structures that allow higher management of those functions are progressively consolidated.

Finally, it’s value noting that not one of the processes that occur on the brain level are isolated from the environment. The influence of the encompassing context can also be key in synaptic pruning.

The stimulation that children receive at an early age allows the brain to consolidate learnings which can be worthwhile, while there’ll be other connections that will likely be left aside. Due to this fact, it’s a matter of making an optimal environment to supply the brain different experiences.

Caring for the brain

From all that has been said, it’s almost a truism to bolster that the brain is an organ of enormous potential and meticulous processes. It might seem that it functions autonomously, almost as if we had no influence over it. Nonetheless, this isn’t so.

Our habits, our weight loss program, the time we dedicate to rest and sport, in addition to mental and leisure activities, are only a few of the aspects that influence the best way by which the brain develops, perfects itself, and grows, and learns.

It looks like an ideal clockwork machine, however it also needs someone to wind it up. And that is where we’ve got our role to play.

That’s why it’s vital to take care of it and listen to it, in search of a life that balances demands with recreation, avoiding prolonged situations of stress, anxiety, and discomfort.
