== <span style="color: #FFFFFF;">Remembering</span> == * '''Reward''' β A "Positive Stimulus" (Food, Sex, Money, Likes) that "Reinforces" a behavior. * '''Motivation''' β The "Internal State" that "Initiates" and "Directs" behavior toward a "Goal." * '''Dopamine''' β The "Key Neurotransmitter" of the reward system: it is **NOT** the "Pleasure Molecule"; it is the **"Wanting Molecule"** (Anticipation). * '''Mesolimbic Pathway''' β The "Dopamine Highway" that runs from the **VTA** (Ventral Tegmental Area) to the **Nucleus Accumbens** (Reward Center). * '''Incentive Salience''' β The "Attractive Quality" of a stimulus: how much it "Grabs your Attention" and "Makes you want it." * '''Wanting vs. Liking''' (Berridge) β The discovery that "Wanting" something (Dopamine) is a "Different Neural Circuit" than "Liking" it (Opioids/Endorphins). * '''Reward Prediction Error''' (RPE) β The "Brain's Calculation" of "Expectation vs. Reality": if a reward is "Better than expected," you get a "Dopamine Spike." * '''Tolerance''' β When the brain "Reduces its Sensitivity" to dopamine because it is "Flooded" by "High-Reward Activities" (e.g. 'Drugs' or 'Social Media'). * '''Anhedonia''' β The "Inability to feel pleasure" or "Motivation," often caused by a "Crashed" reward system (Depression). * '''Intrinsic vs. Extrinsic Motivation''' β (See Article 534). Doing something because you "Love it" vs. doing it for an "External Reward." </div> <div style="background-color: #006400; color: #FFFFFF; padding: 20px; border-radius: 8px; margin-bottom: 15px;">
