the iQ level of average human is 80 to 85% but we people don't use the iQlevel so when we increase the neurons in brain then what is the state of that brain????????????????
Answers
Answer:
yes it changes heres how(neurons and folding of brain)
Explanation:
IQ depends on
Genetic
Our genes do influence intelligence and IQ. Different studies have placed the genetic component at different levels ranging from 30-80%, but it is agreed that the level of genetic influence increases with age, at least from childhood through to early adulthood. Studies also agree that the proportion of the variability of IQ between adult individuals that can be accounted for by genes is 60-80% [14].
Our brain structure and functionality -
contribute to our level of intelligence. Specific features that may affect IQ include the size and shape of the frontal lobes, the amount of blood and chemical activity in the frontal lobes, the total amount of gray matter in the brain, the overall thickness of the cortex and the glucose metabolic rate. Well-functioning pathways correlate to better brain functioning, brain efficiency and information processing, which all point to better IQ scores [15,16]. It should be noted that the correlation with brain size is not simple. Autism is also correlated with brain size in ways that are likely controlled by genes [17], although there are of course disturbed neuronal pathways in autism.
Environmental factors
We may be genetically predisposed to a certain brain volume, structure and pathways -- a certain level of intelligence set by our biology -- but how much we achieve isn’t based in biology alone. The type of life we lead also affects intelligence.
Researchers often study twins who’ve been separated at birth to understand further the roles nature and nurture play in human intelligence. They theorize that if intelligence is purely biological, identical twins separated at birth should still have equal IQs. But that’s not always the case, they find. Genetic effects cause bright children to seek out more stimulating environments that further increase IQ. Programs aiming to increase IQ would be most likely to produce long-term IQ gains if they caused children to persist in seeking out cognitively demanding experiences. Recent studies have shown that training in using one’s working memory may increase IQ. But it is not clear how long improvements persist after training stops [18,19].
Improvements in nutritional policy have been implicated in worldwide increase in IQ [20]. Prenatal and early nutrition are linked to brain structure, behavior and intelligence [21]. There is evidence that providing a high nutrient diet to very premature babies, particularly males, can help to reduce the loss of brain size and IQ often experienced by these babies [22]. Zinc, Iron, folate, iodine, B12 and protein deficiency can also result in low IQ [23-27].
The association between breastfeeding and child cognitive development is conflicted by studies reporting positive and null effects. Relationship may be confounded by factors associated with breastfeeding, specifically maternal socioeconomic class and IQ [28]. One study states that it was the mother’s IQ that had a significant correlation with the IQ of her offspring, whether the offspring was breastfed or was not breastfed [29]. Another study found that breastfeeding had a positive effect on cognitive development at 24 months of age even after controlling for parental IQ [30,31]. A potential resolution to these different interpretations was proposed in a study showing that breastfeeding was linked to raise IQ if the infants had an SNP coding for a “C” rather than G base within the FADS2 gene. Those with the “G” allele showed no IQ advantage, suggesting a biochemical interaction of child’s genes on the effect of breast feeding [32]. How ever another study support the view that apparent effects of breast-feeding on IQ reflect differential likelihood of breast-feeding as a function of parental education and did not support the predicted interaction effect of FADS2 and breast-feeding on IQ [33]. If there is a genetic predisposition for some babies to benefit more from breastfeeding, current knowledge of genotype-phenotype interactions in general suggests that it is probably polygenic, but more research would be needed to confirm this So it may be concluded that Breast feeding may have some small effect on IQ but the effect may be explained by confounding factors including maternal
