The human brain undergoes complex and life-long changes especially at specific stages of development and this process is called maturation. It is a process of brain development in which minor modifications are made to improve the brains efficiency and ability, for example, to communicate. The brain does this by getting rid of redundant pathways or synapses by way of dendritic pruning and continues this remodeling throughout life. Perhaps the most important stages of maturation are during fetal development, early childhood and adolescence. There is individual variation in the maturation process and neuroimaging techniques have enabled the comparison in cortical and sub-cortical changes between different groups of children. A longitudinal neuroimaging study with 45 children aged 5-11 years reported that brain expansion increased by approximately 1 mm per year and predominantly in the frontal cortex. In fact, evidence suggests that the frontal cortex continues to mature well into adulthood and late 20’s (circa: 25-30 years of age). This is in contrast to the limbic system which ignites during puberty and makes the adolescent period a particularly vulnerable time.
Neurons are nerve cells which send electrochemical signals to each other. As a person processes an event, neurons in the brain pass information through synapses (tiny gaps between neurons). This invites surrounding neurons to start firing, creating a network of connections of various strengths. It’s this persistent change in the strength and pattern of connections that is a ‘memory’.
Infantile amnesia, the inability of adults to recollect early episodic memories, is associated with the rapid forgetting that occurs in childhood. It has been suggested that infantile amnesia is due to the underdevelopment of the infant brain, which would preclude memory consolidation, or to deficits in memory retrieval. Although early memories are inaccessible to adults, early-life events, such as neglect or aversive experiences, can greatly impact adult behavior and may predispose individuals to various psychopathologies. It remains unclear how a brain that rapidly forgets, or is not yet able to form long-term memories, can exert such a long-lasting and important influence. Here, with a particular focus on the hippocampal memory system, we review the literature and discuss new evidence obtained in rats that illuminates the paradox of infantile amnesia. We propose that infantile amnesia reflects a developmental critical period during which the learning system is learning how to learn and remember.

Answer: You sound like a person that cannot deal with complete silence or just a little bit of sound. Almost nobody can so that's why we listen to music which is a great way to fill in that empty space, although it is a great risk because it may lead to zoning out and attention loss. Anyway, what music do you like to listen to?
Answer:
<h2>A factor of production will not earn economic rent when its supply is perfectly elastic.Hence,the answer here would be option C. or Perfectly Elastic.</h2>
Explanation:
- In Economics,economic rent is the additional revenue earned by the firm or any company from a certain constant supply of various factors resources or inputs of production.It is computed by taking the difference between the factor income or payment that the factor inputs actually receive and is supposed to receive under the factor market equilibrium conditions.
- One of the important pre-conditions of economic rent extraction is that concerned factors or inputs of production have to be perfectly inelastic or the supply of the factor inputs has to be completely unresponsive or non-reactive to the factor income or factor payments generated by these factors/inputs of production.
- In the case of perfectly elastic supply of the factors/inputs of production,any factor income or payment given to the factor inputs lower than what they are usually supposed to receive then the factor or input supply will be significantly or considerably reduced thereby limiting the ability of the firms or companies to generate any economic rent or additional revenue in the course of regular business operation.
