The Parietal Lobe

The parietal lobe acts as your brain's sensory adaptor, processing touch, temperature, pain, and pressure, while also handling spatial awareness, navigation, and integrating senses (like vision and touch) for coordinated movement and understanding where things are.

PCC (Posterior Cingulate Cortex)

Precuneus

becomes active as a key hub for your memory retrieval and self-reflection, helping to reconstruct past experiences and link them to the present sense of self

acts as a central hub for retrieving vivid personal memories and connecting them to your sense of self

The parietal lobe is involved in processing the spatial and sensory details of nostalgic memories

The Brainstem

The brainstem is the part of the brain that is connected to the spinal cord. It controls many vital functions, such as breathing, heart rate, and blood pressure, and the nerves and muscles used in seeing, hearing, walking, talking, and eating.

Substantia Nigra (SN)

Ventral Tegmental Area (VTA)

When a smell or song hits your senses, the brainstem helps get that information to the rest of your brain

Both the SN and VTA release dopamine during nostalgia. They are associated with reward processing and positive affect.

The Temporal Lobe

The temporal lobe is responsible for processing auditory information, language comprehension, memory formation (hippocampus), emotions, and sensory input like smell, vision, and facial recognition.

Stratium

Hippocampus

The hippocampus is responsible for finding and playing back the detailed, personal memories that are the core of the nostalgia

The striatum acts like the brain's "reward center" for nostalgia, releasing dopamine to make remembering positive memories feel good and motivating you to seek that good feeling again

The temporal lobe essentially links what we hear, see, and remember with meaning and feeling.

The Frontal Lobe

Frontal lobe functioning involves both simple and complex motor skills. The frontal lobes also control attention, reasoning, judgment, problem solving, creativity, emotional regulation, and impulse control.

vmPFC (Ventromedial PFC)

mPFC (Medial Prefrontal Cortex)

The frontal lobe serves as the integration hub for nostalgia, coordinating self-reflection, emotion regulation, and reward processing.

responds to the pleasant, positive emotional aspects of nostalgia and assigns personal significance to nostalgic content

integrates self-relevant information with memories, helping process the personal significance of nostalgic experiences

ACC (Anterior Cingulate Cortex)

regulates the bittersweet experience of nostalgia, helping manage the simultaneous positive and negative feelings through cognitive reappraisal
