pathways

HHappiness

1. Brain Regions:

   • Medial Forebrain Bundle: Associated with reward and pleasure pathways.

   • Nucleus Accumbens: Plays a key role in reward and reinforcement.

   • Ventral Tegmental Area (VTA): Releases dopamine, initiating reward signaling.

   • Cingulate Cortex: Involved in emotional processing and decision-making.

2. Neurotransmitters/Hormones:

   • Serotonin: Contributes to mood regulation and well-being.

   • Dopamine: Central to pleasure and reward.

   • Oxytocin: Enhances social bonding and trust.

   • Endorphins: Provide pain relief and promote feelings of euphoria.

Sadness

1. Brain Regions:

   • Cingulate Cortex: Processes emotional pain and regulates sadness.

   • Amygdala: Plays a role in negative emotional processing.

   • Insula: Involved in the perception of emotions and bodily states.

2. Neurotransmitters/Hormones:

   • Serotonin: Decreased levels are linked to sadness and depression.

   • Norepinephrine: Regulates arousal and mood; imbalances are linked to depression.

   • Dopamine: Reduced activity in reward pathways contributes to low motivation and anhedonia.

Fear + Anger

1. Brain Regions:

   • Amygdala: Central to processing threats and triggering fear responses.

   • HPA Axis: Regulates the stress response by releasing stress hormones.

   • Sympathetic Nervous System: Activates fight-or-flight responses.

2. Neurotransmitters/Hormones:

   • Cortisol: Released by the adrenal glands; prepares the body for stress.

   • Epinephrine (Adrenaline): Increases heart rate and energy availability.

   • Norepinephrine: Enhances alertness and focus during stress.
