= How the environment affects the brain? =

The brain is a dynamic system that interacts with the environment. In a sense, the brain is physically sculpted by experience.

 **Brain plasticity ****// (Scientifically called Neuroplasticity) //**

Brain plasticity refers to the brain’s ability to rearrange the connections between its neuron – that is, the changes that occur in the structure of the brain as a result of learning or experience. The changes that take place are related to the challenges of the environment and therefore represent an adaptation to it.

**1. __Aim __** To find out which environment develops neurons in the cerebral cortex? **2. __Procedure __** a. Placed rats into one of two environments i. Enrich, stimulating environment with toys ii. Deprived environment without toys b. Rats spent 30 to 60 days

**<span style="background: white; color: black; font-family: 맑은 고딕;">3. __Findings__ ** <span style="font-family: 맑은 고딕;">a. Rats in the stimulating environment had an increased thickness in the cortex. b. The frontal lobe (thinking, planning g, decision making) was heavier in the rats that had been in the stimulating environment. c. Having toys created the best conditions for developing cerebral thickness.

a. These findings can be generalized to human only to some extent. b. Since human brains differ in terms f genetic make-up and the environmental inputs that they receive, it is difficult to decide what is considered to be an enriched environmental for a specific person.
