What happens in your brain when you are grieving?

Updated

Grief triggers the amygdala for emotional salience, anterior cingulate for social pain, insula for visceral feelings, hippocampus for memories, and prefrontal cortex for attempted regulation.

Amygdala, Anterior Cingulate Cortex, Insula, Hippocampus, Prefrontal Cortex lit up on the Brain Atlas 3D brain: what happens in your brain when you are grieving
Figure. The brain regions that light up when you are grieving, in order: Amygdala (emotional alarm), then Anterior Cingulate Cortex (social pain), then Insula (bodily grief), then Hippocampus (memory flood), then Prefrontal Cortex (attempted control).

Brain regions that light up

OrderRegionWhat it does here
1AmygdalaThe amygdala detects the loss as a highly salient emotional event, triggering sadness and distress.
2Anterior Cingulate CortexThe anterior cingulate cortex processes the emotional pain of separation, akin to physical pain.
3InsulaThe insula processes the visceral feelings of grief, such as heaviness and tears.
4HippocampusThe hippocampus retrieves vivid memories of the deceased, fueling longing and rumination.
5Prefrontal CortexThe prefrontal cortex tries to regulate the overwhelming emotion, often with limited success.

1. Amygdala: emotional alarm

Step 1 of what happens in your brain when you are grieving: Amygdala lit on the Brain Atlas 3D brain

The amygdala rapidly evaluates the emotional significance of the loss, activating the stress response. It biases attention toward grief-related cues and enhances memory consolidation of the event. This initial alarm sets the stage for the intense emotional experience.

2. Anterior Cingulate Cortex: social pain

Step 2 of what happens in your brain when you are grieving: Amygdala, Anterior Cingulate Cortex lit on the Brain Atlas 3D brain

The anterior cingulate cortex is a key node for pain processing, both physical and social. In grief, it responds to the separation from the loved one, registering the distress as painful. This region also monitors conflict between the desire to reunite and reality.

3. Insula: bodily grief

Step 3 of what happens in your brain when you are grieving: Amygdala, Anterior Cingulate Cortex, Insula lit on the Brain Atlas 3D brain
Figure 3. Insula, bodily grief: The insula processes the visceral feelings of grief, such as heaviness and tears.

The insula integrates interoceptive signals from the body, representing the physical sensations that accompany grief. It is also involved in empathy and self-awareness, intensifying the feeling of loss. Activation here is thought to contribute to the 'broken heart' sensation.

4. Hippocampus: memory flood

Step 4 of what happens in your brain when you are grieving: Amygdala, Anterior Cingulate Cortex, Insula, Hippocampus lit on the Brain Atlas 3D brain

The hippocampus plays a central role in episodic memory, recalling specific moments shared with the lost person. These memories can be triggered by cues and lead to waves of grief. The hippocampus also helps consolidate the reality of the loss into long-term memory.

5. Prefrontal Cortex: attempted control

Step 5 of what happens in your brain when you are grieving: Amygdala, Anterior Cingulate Cortex, Insula, Hippocampus, Prefrontal Cortex lit on the Brain Atlas 3D brain

The prefrontal cortex, especially its dorsolateral and ventromedial parts, is involved in emotion regulation and reappraisal. In grief, it attempts to downregulate the amygdala and insula responses, but chronic stress can impair its function. This leads to difficulty concentrating and decision-making, common in bereavement.

Good to know

  • The nucleus accumbens, typically associated with reward, shows altered activity in grief, reflecting the craving for the deceased.
  • Grief-related stress can elevate cortisol levels, which over time may impair hippocampal function and memory.
  • Some studies suggest that grief and depression share neural features, but grief typically resolves without clinical intervention.

Grief vs. Depression

While grief and depression share overlapping regions like the anterior cingulate and prefrontal cortex, grief is typically triggered by a specific loss and involves intense yearning. Depression often involves more global anhedonia and self-critical thoughts, with less focus on the lost person.

Simplified: many regions work together at once, and this shows the main players in the order they act.
