Babies are born with billions of brain cells. how many brain connections do babies have by the time they are three years old? describe three factors that contribute to the brain connections multiplying.

Babies have around one trillion brain connections by the age of three years old.

The top three factors that contribute to brain connections are:

1.- motor early stimulation.

2.- language early stimulation

3.- music-playing sessions early stimulation.

Explanation:

All right, to understand this question we need to remember a few things.

First of all, the size of a neuron is 0.1 millimeter and the size of a baby's around 341 cubic centimeters. Also, it is believed that babies born with 100 billion neurons. So, that is a perfect fundament to support that babies can have around one trillion brain connections by the age of three years.

Now, the best contributor to brain connections is Motor early stimulation, because babies born without a sophisticated motor ability and they need to discover movement to survive, which will stimulate amazingly nice brain connections because there will be different connections to move a single finger. Therefore, motor early stimulation will make them develop a high number of connections.

The second best brain connections' contributor is early language stimulation. The reason this is so important is that the cerebellum is coordinated with neocortex and many language brain zones that connect when a language is learned. They keep growing the more we know about that language and the more languages we know. So it is also a very impressive way to simulate brain connections.

The third one is playing and music sessions activities. Why? well basically because playing and music involve 4 major brain stimulants. Language, sound, movement, and interaction. Thus it is a very powerful tool to develop brain connections.

well the unjest treatment and discrimination did get faced by the idians and soldiers
