Mystery of baby’s brain

A baby's brain is a mystery whose secrets scientists are just beginning to unravel. The mystery begins in the womb. According to neuroscience, the first simple synaptic contacts of human brains start during the fifth month of pregnancy.

Architect of baby’s brain

During infancy, baby’s experiences result in building neural connections. Learning strengthens the connections in a neural network, and the environmental inputs through the sensory stimuli shape the architecture of the baby’s brain.

Can baby learn with immature brain?

Evidence showed that synaptic reorganizations also occur in the immature brain, where a neuron may lose or increase connections that it had initially established through certain stimuli.

Architect of Baby’s Brain

The development of the nervous system does not stop at birth. The mechanism of synaptic reinforcement associated with neuronal activity continues to influence a baby’s synapses after birth. At birth a baby’s brain already has about 200 billion neurons, which is about the same number as it will have in adulthood. The difference is that there are very few neural pathways have formed, the bundle of neurons right there waiting to be wired into the intricate circuitry that we call the mind. This is why babies are particularly open to learning during their first years of life. In response to the demands of the world, the baby’s brain sculpts itself, billions of neurons were primed to organize themselves and make the connections in response to the new environment.

Therefore, during infancy, baby’s experiences in the larger world result in building connections between neurons, which are reinforced as the experiences repeated. Learning strengthens the connections in a neural network, and the environmental inputs through the sensory stimuli, such as learning to read, shape the architecture of the baby’s brain. This eventually becomes the neural circuitry integrated to the nervous system, which lays the foundation for the baby’s learning life long. The memories stored in a computer can be cleared at any time, but the first memories formed in baby’s brain last permanently. It is the circuits laid down during these processes that become the source of the baby’s vast repertoire of behaviors and learning.
