Question

What does your brain do with connections it doesn't use?

Answer 1

Answer:

This is synaptic pruning- it removes them

Explanation:

The gaps and the portions of neurons  between adjacent neurons is called synapse.It role is to moderate synaptic connections among neurons.

As organisms (man and other higher animals)develop  from birth to adult,new synaptic connections are formed,and old ones are removed.The process whereby the the axon and dendrite, as part of the synapse, decay  and removed by the brain is called  synaptic pruning or pruning process.

This process begins at childhood and continue till maturity- at mid twenties.it occurs during sleep.

it helps to improve learning and memory,because new connections are  made to replace the old ones,and therefore smooth transition of the brain from childhood to adulthood

Three models have been used to explain pruning-Axon degeneration,retraction and Axon shedding.
