NeuroSomatic Bilateral Integration (NSBI)
Nervous system regulation, without the performance.
NeuroSomatic Bilateral Integration (NSBI) is a trauma-informed, nervous-system-based therapeutic approach developed within the Berrocal Method™️ by Dr. Elizabeth Berrocal. NSBI integrates bilateral sensory stimulation with somatic awareness and autonomic nervous system regulation to support adaptive processing, embodied integration, and restoration of self-regulatory capacity.
NSBI is designed to work at the intersection of neurobiology, somatic psychology, and attachment-based therapy. Rather than focusing solely on cognitive reprocessing or memory desensitization, NSBI emphasizes present-moment bodily experience, titrated nervous-system activation, and relational attunement. Bilateral stimulation is utilized as a supportive neurophysiological tool to facilitate integration while maintaining an active focus on somatic tracking, autonomic state shifts, and embodied meaning-making.
Rooted in Dr. Berrocal’s clinical synthesis and scope of practice, NSBI reflects her foundational understanding that trauma is not simply remembered cognitively — it is stored, patterned, and expressed through the body and autonomic nervous system. This model was uniquely designed through her integrative lens of EMDR-informed bilateral stimulation, somatic embodiment practices, and attachment-based relational repair.
NSBI represents a distinct clinical construct within the Berrocal Method™️, and Dr. Berrocal is currently training and certifying practitioners in this proprietary framework, equipping clinicians to apply bilateral stimulation within a regulated, body-based, and trauma-attuned model of integration.
NeuroSomatic Bilateral Integration (NSBI) was developed through the clinical and somatic work of Dr.Elizabeth Berrocal, in response to a recurring pattern they observed in both individual and group settings:
People understood their experiences — but their nervous systems had not caught up.
Many clients arrived highly insightful, self-aware, and articulate, yet remained dysregulated, hypervigilant, shut down, or chronically “on.” Traditional talk-based approaches were not enough. Likewise, unstructured somatic or cathartic experiences often overwhelmed the system rather than supporting integration.
NSBI was created to fill that gap.
The method emerged as a bridge between clinical understanding and embodied regulation — offering a structured, trauma-informed way to help the nervous system settle before deeper work is introduced.
It was designed specifically for:
-
Individuals who feel stuck despite insight
-
Helpers and clinicians who live in chronic activation
-
Group environments where safety and containment are essential
-
Bodies that need regulation, not explanation
NSBI is not meant to impress. It is meant to work.
What Happens in an NSBI Session
NSBI sessions are structured, contained, and intentionally slow. Depending on the context, facilitation may include:
-
Alternating bilateral movement or stimulation
-
Rhythmic tapping, rocking, or paced sensory input
-
Breath paired with sound or tone
-
Guided somatic orientation and tracking
-
Strategic pauses for integration
There is no requirement to share personal history or “process” experiences verbally. The body leads. We follow.
