• Acetylcholine (anagram: ace to cool) neurons form neuromodulatory connections to the cortex that are particularly important for focused learning, when you are paying close attention.
  • Acetylcholine lead you to new long term memory.
  • Neuromodulators also have a profound impact on your unconscious mind.
  • To sum up acetycholine is for these.
    • Preparing long term memory.
    • Unconscious mind.
• Dopamine.
  • Dopamine controls motivation.
  • Dopamine controls rewards on learning.
  • Dopamine is released from certain neuron when human receive an unexpected rewards.
  • Dopamine effects decision making.
  • Dopamine effects sensory input.
  • Dopamine is in the business of predicting future rewards and not just the immediate reward.
  • This can motivate you to do something that may not be rewarding right now but will lead to a much better reward in the future.
  • Addictive drugs artificially increase dopamine activity and fool your brain into thinking that something wonderful has just happened.
  • However, drugs do harmful things to human body and fool your brain into thinking that something wonderful is just happening.
  • Drugs also creates dependency.
  • Lacks of Dopamine leads to lack of motivation.
  • When you promise to treat yourself something after a study section you are tapping into your dopamine system.
  • Severe loss of Dopamine neurons causes rigidity, slowness, and tremor. This is what it is called by Parkinson's disease.
  • Summation.
    • Dopamine controls motivation.
    • Dopamine controls reward on something that you have do, accidentally or deliberately.
    • Dopamine effects decision making.
    • Dopamine effects sensory input.
    • Dopamine predicts your future and immediate reward.
    • Lack of Dopamine neuron is called Parkinson's disease.
• Serotonin.
  • Serotonin (anagram: sero to ninja) is a third diffuse neuromodulatory system that strongly affects your social life.
  • In monkey troops the alpha male has the highest level of serotonin activity and the lowest ranking male has the lowest levels.
  • The level of Serotonin is also closely linked to risk taking behavior. With higher risk in lower Serotonin monkeys.
  • Inmates in jail for violent crimes have some of the lowest levels of serotonin activity in society.
  • Summation.
    • Serotonin effects risk taking behavior.
      • For example people that lack of Serotonin would likely to do crime than people who has normal Serotonin.
    • Serotonin effects social life.
• The Amygdala is part of the limbic system which together with Hippocampus is involved in processing memory and decision making as well as regulating emotional reactions.
• You will want to keep your Amygdala happy to be an effective learner.
