will be discussed are the enrichment of certain environments on brain plasticity and the observation of experiences actions on the activation of mirror neurons. The first effect of environment on physiological processes that will be discussed is brain plasticity. Brain plasticity is the brain’s ability to rearrange its connections with its neurons‚ that is‚ the changes that occur in the structure of the brain as a result of learning or experience (exposure to different environments). The changes

and its extinction. In the present study we worked towards the hypothesis that the differential activation of the neuronal subpopulations in the BNST and Amygdala is due to different expression patterns of memory related genes such as CREB in the neurons in these sub-regions and that this differential expression may be under the control of epigenetics especially Histone

Using a Blue Gene supercomputer running Michael Hines’sNEURON software‚ the simulation does not consist simply of an artificial neural network‚ but involves a biologically realistic model of neurons. It is hoped that it will eventually shed light on the nature of consciousness.
