Plasticity of the Nervous System

Plasticity of the Nervous System

1. Definition

   • “plasticity” which means modifiable
     • relationship among two people who have a same ancestor or blood
   • “neuro” which means the nerves

2. The Limits of Innate Brain Plasticity

   • example
     • Huntington’s disease
       • degenerative disease which case death of a large number of neurons that cannot simple be recovered
   • massive brain damage that the plasticity of the neurons in no more able to recover the lost function

3. Role in Homeostasis

   • the ability on the neurons to manage its excitability associated to its activity
   • the suggested components that prompt compensative changes in trauma injury is named as "homeostatic plasticity ".

4. Clinical Implications

   • brain can change responding to many factors as in environmental factors
   • it also can do some changes responding to a disease or even injury
     • axonal sprouting
       • intact nerves axons arise new endings to have back the lost connections of the damaged ones
   • can enhance other functions responding to a loss of one of them
     • many blind people, these areas can adapt to another different process such as enhancing the hearing or even the touch.

5. coclusion

   • Further research in neuroplasticity can provide more data to improve many medications and strategies to face many diseases
