For a long time, it was believed that as we aged, the connections in the brain became fixed, and then simply faded. Research has shown that in fact the brain never stops changing through learning. Plasticity is the capacity of the brain to change with learning.

The Immune brain Loop – Further info! Cell signaling networks and Signal transduction – PNI research is looking for the exact mechanisms by which specific brain effects are achieved. Evidence for nervous system immune system interactions exists at different biological levels. The immunity system and the brain talk to one another through signaling pathways. The brain and the immunity system are the two main adaptive systems of the body. Two major pathways are involved with this cross-talk: the Hypothalamic pituitary adrenal axis and the sympathetic nervous system. The activation of SNS during an immune response could be aimed to localize the inflammatory reaction.
