Major Factors That Influence Brain Development - Deepstash

Major Factors That Influence Brain Development

  1. Genes - are a major key factor in brain development due to their contribution to normal individual variation in brain development, and relatively rare genetic alterations.
  2. Environmental factors - Because having a safe and nurturing environment facilitates proper growth.

Neurogenesis and Neuronal Development
  • Neurogenesis is the process by which new neurons are created. The bulk of this process happens during the prenatal period of brain development.
  • Synaptogenesis is the process of forming connections or synapses.
  • Synaptic pruning is the process where synapses that aren't used grow weaker and disappear.
  • Myelination is a key process in neuronal development that begins before birth

Stages of Early Brain Development

Brain development happens at different rates for different parts of the brain but here are the major trends in the construction that takes place:

  • In the womb: folding of the brain's outer layer
  • Newborn - childhood: the brain grows gradually and continues to develop white matter pathways and maturity of movement and sensation
  • Adolescence: gray matter thins out; synapses scale back, and susceptibility to outside influence heightens
  • Early adulthood: the prefrontal cortex is still developing.

We might have this idea that our brains change the same way but scientists have observed that there is a considerable variation between individuals in terms of when and what to extent aspects of the brain change.

Individual differences in brain development can be related to psychological differences.

Neuroplasticity
  • Also known as neural plasticity
  • This is the capacity of the brain to change in response to experience and the environment.
  • It changes the brain from updating the neuronal networks to the formation of new memories to larger structural adaptations.
  • The brain has a great amount of plasticity and it remains an essential quality of the brain throughout adulthood.

Brain Growth

It's been thought that the neurons were already created before birth, but research indicates that the brain keeps growing until mid to late childhood, decreases through the early 20s, stabilizes for quite a while, and then begins to decrease further from age 40 onwards.

Neuroplasticity: The Brain’s Ability To Adapt

The human brain is not static, but is shape-shifting, upgrading, maintaining and housekeeping itself all the time.

The constant rewiring, adapting and upgrading is happening not just in our formative years, but through the course of our lifetime. This neuroplasticity of the brain can be nurtured and stimulated for further development.

Learning throughout life

The proliferation of new neurons is astounding, but as we get older, this capacity decreases.

Nevertheless, neurogenesis  continues even when we get older. The old belief that we’re born with a determined number of neurons, and that throughout life we do nothing more than lose them, is false. There is a decline in neuroplasticity, but the brain continues to be considerably malleable.

The human brain vs. the computer

When we contemplate which has more problem-solving power, the brain or the computer, we might think that the modern computer would come out on top. Indeed, computers have been built and programmed to beat human masters in complex games, such as chess.

However, humans still trump computers in many real-world tasks, such as identifying a particular pedestrian on a crowded city street. Computers are unable to beat humans at conceptualization and creativity.
