1.     Explain and define the concepts brain neuroplasticity, neurogenesis, and brain lateralization.

Solution

1. Brain Neuroplasticity: the brain’s ability to change its structure and function in response to experience or damage and it can be said as brain\'s flexible.

Some of the controls like movement, vision, and hearing, are performed in specified areas of the cortex, if any damage to these areas, the individual will lose the ability to perform the corresponding functions. (For eg: Individual with damage in the facial recognition areas in the temporal lobe might lose the ability to recognize face), And the brain has the capacity to extend themselves to carry out particular functions in response to the needs of the organism. Thus the brain will try to create new neural communication routes and rewires existing ones. This phenomenon is said to be brain neuroplasticity.

2. Brain neurogenesis: the forming of new neurons.

Neurogenesis occurs because the brain cannot repair or regenerate themselves as skin or blood vessels can. These formations of new neurons in the deep of the brain can migrate to the other parts of the brain to form a new connection with other neurons.

3. Brain lateralization: can be defined as the left and the right hemispheres of the brain are specialized to perform a different function.

For example, both the left and the right hemispheres of the brain perform function relate to the language part but in most people, grammar and vocabulary functioned by the left hemisphere, while understanding the emotional content of a language functioned by the right hemisphere. This phenomenon is said to be brain lateralization
