If you're in an impoverished environment, it is thought that your cortex will shrink and become more dense.

It was also found that rats that were originally in the impoverished environment only took two hours to adapt and have the same brain plasticity as those who were in their longer. This shows that the environment does have an effect on the brain and brain size can change.  ]]> 2018-01-29 17:07:44 UTC https://padlet.com/tranch/ktpsj8k1qll6/wish/225735031 https://padlet.com/tranch/ktpsj8k1qll6/wish/225737131 another environmental effect is on the trauma that happens with in our brains ]]> 2018-01-29 17:11:08 UTC https://padlet.com/tranch/ktpsj8k1qll6/wish/225737131 https://padlet.com/tranch/ktpsj8k1qll6/wish/225737635 the study was to investigate the effects of trauma on the hippocampus. they were people that were sexually abused as child or combat veterans returned from war. it was found that the hippocampus was smaller in PTSD than the control group. veterans with bad STM had small hippocampus. sexual abuse was connected to memory problems and small hippocampus. ]]> 2018-01-29 17:11:54 UTC https://padlet.com/tranch/ktpsj8k1qll6/wish/225737635 https://padlet.com/tranch/ktpsj8k1qll6/wish/225738564 Environment can effect brain plasticity, enriched environments can reform or rearrange connections between neurons which can lead to a different structure in the brain]]> 2018-01-29 17:13:29 UTC https://padlet.com/tranch/ktpsj8k1qll6/wish/225738564 https://padlet.com/tranch/ktpsj8k1qll6/wish/225739680 Another environmental factor that effects physiological processes is environmental stressors; trauma.

It was found the hippocampus was smaller in participants with PTSD rather than the control group. Veterans w the worst STM had the smallest hippocampus. The length of sexual abuse correlates w memory probs/ smaller hippocampus. The study shows people with longer/ more severe trauma had the smallest hippocampus, correlating with their bad memory]]> 2018-01-29 17:17:58 UTC https://padlet.com/tranch/ktpsj8k1qll6/wish/225741241 https://padlet.com/tranch/ktpsj8k1qll6/wish/225742623 A study to investigate whether environment affects neuron development.
