Neuroscience research has dramatically advanced our understanding of sensory processing disorder's mechanisms, informing better treatments and reducing stigma.
Key Brain Structures in Sensory Processing Disorder
Modern neuroimaging has identified consistent patterns in sensory processing disorder:
- Amygdala: Threat processing center shows altered activation patterns in sensory processing disorder
- Prefrontal Cortex: Top-down emotional regulation — often underactive in sensory processing disorder
- Anterior Cingulate Cortex: Conflict monitoring and pain processing — implicated in sensory processing disorder
- Hippocampus: Memory and context; chronic stress in sensory processing disorder can affect its volume
- Default Mode Network: Rumination and self-referential thinking network — often overactive in sensory processing disorder
Neurochemistry of Sensory Processing Disorder
While the 'chemical imbalance' model is oversimplified, neurotransmitter systems play real roles in sensory processing disorder:
- Serotonin regulates mood, appetite, and sleep — all affected in sensory processing disorder
- Dopamine drives motivation and reward — disrupted in many sensory processing disorder presentations
- GABA and glutamate modulate excitation/inhibition balance relevant to sensory processing disorder
What Neuroscience Means for Sensory Processing Disorder Treatment
Neuroscience validates that sensory processing disorder is a brain condition, not a character failing. It points toward treatments that target specific mechanisms — and shows that both therapy and medication physically change the brain.
