Imagine a world where clothes feel like sandpaper, everyday sounds are overwhelming, or even balancing is a daily challenge. For those struggling with sensory integration dysfunction, these experiences are part of their reality. This condition, where the brain struggles to process and respond to sensory input, is often misunderstood. While sensory integration issues are commonly linked to conditions like autism or Sensory Processing Disorder (SPD), another hidden factor could be at play: retained primitive reflexes.
Primitive reflexes are essential movement patterns present in infants that should disappear as a child’s brain matures. However, when these reflexes don’t integrate properly, they can cause various issues, including sensory processing challenges. This post will explore how retained primitive reflexes can disrupt sensory integration and how addressing them can bring significant relief.
What Is Sensory Integration Dysfunction?
Sensory integration dysfunction happens when the brain has difficulty interpreting and organizing sensory information. Our senses—touch, taste, smell, sound, sight, movement, and body awareness—send constant data to the brain, helping us navigate our environment with ease.
However, when sensory integration is disrupted, the brain may misinterpret or fail to organize this input. For instance, a person might overreact to normal levels of sound or light, experience discomfort from everyday touch, or feel disoriented by movement. This can lead to a chaotic and unpredictable perception of the world, affecting emotional, cognitive, and physical well-being.
The Role of Retained Primitive Reflexes in Sensory Integration Dysfunction
Primitive reflexes are involuntary movements that develop during infancy to support survival. For example, the rooting reflex helps a baby find its mother’s breast to feed, while the Moro reflex prepares infants to respond to sudden changes in their surroundings. These reflexes should integrate into higher brain functions as a child grows.
However, when these reflexes fail to integrate properly, they remain active, disrupting the brain’s ability to process sensory input. These retained reflexes can block efficient filtering and organizing of sensory information, leading to sensory overload or confusion.
Which Retained Reflexes Impact Sensory Processing?
Certain retained reflexes are closely linked to sensory integration dysfunction. Below are the key reflexes and how they affect sensory processing:
1. The Moro Reflex
The Moro reflex, or startle reflex, is a survival mechanism for infants, triggered by sudden environmental changes like loud noises or quick movements. When retained, this reflex causes a hypersensitive nervous system, leading to overreactions to sensory stimuli.
Individuals with a retained Moro reflex may experience sensory overload, where everyday sights and sounds feel overwhelming. This can make noisy environments, bright lighting, and unexpected stimuli difficult to tolerate, causing anxiety.
How It Affects Sensory Integration:
- Sensitivity to light, sound, and touch
- Increased startle responses, making relaxation difficult
- Heightened anxiety in busy environments
2. The Tonic Labyrinthine Reflex (TLR)
The TLR is crucial for the development of balance and spatial awareness. Activated by head movement, it impacts muscle tone and posture in infants. When not properly integrated, this reflex can lead to balance and coordination challenges.

Individuals with a retained TLR may feel dizzy, experience motion sickness, or struggle with physical activities like running or climbing. Adults may have difficulty navigating spaces, leading to a sense of unsteadiness.
How It Affects Sensory Integration:
- Trouble with balance and posture
- Sensitivity to motion (e.g., nausea in moving vehicles)
- Poor spatial awareness, resulting in frequent stumbling or bumping into objects
3. The Spinal Galant Reflex
The Spinal Galant reflex helps during birth and early movement by causing the infant to flex when their spine is stimulated. When retained, it can cause hypersensitivity in the lower back.
Children and adults with a retained Spinal Galant reflex may struggle to sit still, experience discomfort from clothing, or react to subtle stimuli like the feeling of a chair against their back.
How It Affects Sensory Integration:
- Hypersensitivity to touch, especially along the spine
- Difficulty sitting still for long periods
- Discomfort from tactile stimuli like clothing tags or certain fabrics
4. The Asymmetrical Tonic Neck Reflex (ATNR)
The ATNR develops eye-hand coordination by causing the arm on the side a baby’s head is turned to extend, while the other bends. When retained, this reflex can interfere with fine motor skills and hand-eye coordination.
A child with a retained ATNR may have trouble performing tasks that require both hands, such as writing or catching a ball. Adults may struggle with similar activities, making everyday tasks frustrating.
How It Affects Sensory Integration:
- Poor hand-eye coordination
- Difficulty with activities requiring crossing the body’s midline
- Challenges with writing, cutting, or sports
The Emotional Impact of Sensory Integration Dysfunction
Sensory integration dysfunction affects not only physical responses but also emotional well-being. When sensory input feels overwhelming, it can lead to chronic anxiety, frustration, and social withdrawal.
Children may struggle to concentrate in school or feel embarrassed by their inability to complete tasks. Adults may avoid noisy or crowded places due to stress. Over time, this can cause emotional burnout, diminishing resilience and making it harder to cope with sensory overload.
How In the Cortex’s Brain Reorganization Program Can Help
If you or your child struggles with sensory integration dysfunction, the In the Cortex Brain Reorganization Program can help. This program targets retained primitive reflexes and improves sensory processing by addressing underdeveloped brain pathways.
Through customized exercises, the program helps integrate retained reflexes, improving balance, coordination, and sensory regulation. Participants often experience a reduction in sensory overload and emotional distress, gaining more confidence in daily life.
