Factors influencing brain development

Heredity = make sure thing are go wright and the brain will continue growing and restructure itself..
Nutrition = good nutrition-vitamin,mineral,other food supplement..
Environmental toxin = eg: alcohol, mercury, radiation...
Opportunities to learn = learn to read and write > different organizational pattern in our brain...

Our Brain

Do you know your brain's size?

Alright guys, I will share with you some information that I learn from my class.

When we are born,our brain weight is 400 grams.

 when we are 18 months old, it become bigger with the weight 800 grams.

 Then, when we are adult, our brain will turn to 1300-1400 grams.. 

So, can you guess your brain's weight now??...have a fun..(",)
