![]() Altered stress systems: CRF, Amygdala, and HPA axis.Hypofrontality: Weakening of the impulse control circuits.Sensitization: Formation of Pavlovian memory circuits related to the addiction.Desensitization: Weakening of circuits related to natural rewards (e.g.In a very simplified model, the major addiction-related brain changes include: Neuroplasticity works in two directions: it can weaken or delete old connections as well as strengthen or create new connections. The above mechanisms are at work during brain development, learning, memory formation, and the development of addiction. Increase or decrease in the strength of a synapse: Same as above.Decrease or increase in the number of synapses: Helps to determine strength of pathways, information flow, learning and memories.Increase or decrease in number of dendrites (gray matter): These branch-like fibers are where nerve cells communicate.Increase or decrease in myelin sheath (white matter): Covers nerve fibers to increase the speed of nerve impulses.Brian plasticity occurs on multiple levels and includes (but is not limited to): Neuroplasticity does not consist of a single type of brain change, but rather includes several various processes that occur throughout an individual’s lifetime. Neuroplasticity is the lifelong ability of the brain to reorganize neural pathways based on new experiences. Rewiring and unwiring refers to neuroplasticity or brain plasticity.
