Sadness

Short answer: A 2020 multidisciplinary review describes sadness as a normal emotion with distributed brain correlates. These include the subgenual anterior cingulate cortex, the dorsal periaqueductal gray and changes in frontal activity, along with altered autonomic control of the heart.

The review treats ordinary sadness and clinical depression as related but distinct. The Reel's specific neurotransmitter claims are simplifications that these sources don't directly support.

Video transcript: Sadness: What Changes in the Brain When We Feel Sad

DID YOU KNOW? Sadness involves coordinated changes across the brain's emotional, reward, and physiological systems. Dopamine signaling often decreases in reward-related circuits, contributing to reduced motivation and pleasure, while changes in serotonin and norepinephrine signaling can affect mood, arousal, and behavioral regulation. NOW YOU KNOW!

The write-up

What changes in the brain when we feel sad. Many brain systems are involved, and sadness isn't the same as depression.

  1. Exhibit A

    A normal emotion

    Sadness is a basic emotional response to loss and disappointment, and it is distinct from clinical depression. The 2020 review brought together psychology, neuroscience and clinical perspectives on it.

  2. Exhibit B

    Distributed circuitry

    The review links sadness to distributed brain circuits, including the subgenual anterior cingulate cortex and the dorsal periaqueductal gray, along with changes in frontal brain activity.

  3. Exhibit C

    The body

    Sadness is also associated with changes in autonomic control, including the regulation of heart rate.

  4. Exhibit D

    Reward and pleasure

    Kringelbach and Berridge separate 'wanting' (motivation, which dopamine supports) from 'liking' (pleasure, which depends on opioid hotspots). A loss of motivation and a loss of pleasure aren't necessarily the same change.

  5. Exhibit E

    Simplifications

    Statements like 'dopamine decreases' or 'serotonin changes' compress a complicated, still-debated picture. Neurotransmitter effects differ by circuit, context and person.
