Why BLS Works: A Free Live Event With Dr. Amy Serin
If you’ve been using bilateral stimulation in your trauma work, chances are you learned it as one piece of a bigger protocol. You tap, you use tones, you move your fingers — and you trust the process.
But here’s a question that doesn’t come up enough: do you actually know what’s happening in the brain when you do it?
Not in a vague, hand-wavy way. But truly — why does one type of BLS calm a client down while another leaves them agitated? Why does the speed matter? Why does tactile feel different from auditory? And what happens when you get it wrong?
These are the kinds of questions that can completely change how you work. And they’re exactly what’s on the table at an upcoming free Clinical Conversation happening on April 15th, 2026, (Wednesday) from 1:00 p.m. to 2:00 p.m. (CST) entitled: Decoding the Mystery of BLS: What it Really Does in the Brain and Why You Should Use It More.
The event will be hosted by Trauma Therapist Institute. You’ll be surprised to find out how the answer is more fascinating and more clinically useful than most people realize.
BLS Is More Nuanced Than Most of Us Were Taught
Here’s something a lot of therapists quietly wonder but rarely say out loud: “I use BLS, but I’m not totally sure why I’m making the choices I’m making.”
Maybe you default to the same speed every session. Maybe you switch between tapping and tones based on client preference but aren’t sure if there’s a clinical reason behind it. Maybe you’ve had a client flood unexpectedly and wondered if the BLS contributed.
You’re not alone in that. The truth is, most training covers BLS as a procedural element — here’s how to do it, here’s when to use it — without going deep into the neuroscience of why different forms work differently.
Different types of BLS — tactile tapping, auditory tones, visual tracking — don’t all do the same thing. The modality matters. The speed matters. The intensity matters. And when you understand how each of these variables affects the nervous system, you stop guessing and start making intentional, calibrated choices that actually serve your clients better.
Here’s What You’ll Walk Away With
This isn’t a surface-level overview. In this live conversation, you’ll explore:
- What’s actually happening neurologically when you use different forms of BLS — and why they’re not interchangeable
- How to tell in real time whether BLS is calming your client or pushing them toward overwhelm
- How to adjust on the fly based on client feedback, rather than sticking to one-size-fits-all settings
- Safe ways to extend BLS support outside of session, particularly for clients in underserved communities who need more between appointments
- How to use BLS for yourself — yes, you — to reduce the cumulative stress of doing trauma work day in and day out
That last one is worth sitting with. Burnout among trauma therapists is real. The idea that BLS can be a tool for your own nervous system regulation, not just your clients’, is something most people haven’t considered.
Why This Conversation Is Different
You’ve been to webinars before. You know the format: someone talks at you for an hour, you take notes, you leave with a PDF, and maybe 20% of it sticks.
This isn’t that.
The Clinical Conversations at Trauma Therapist Institute are designed to feel like exactly that — a conversation. Bring your clinical stuck points. Bring the case that’s been nagging at you. Bring the question you’ve been too hesitant to ask in a more formal setting.
This is a space that’s honest, raw, and genuinely useful — not polished and performative. You’re welcome to show up exactly as you are, whether you’re a seasoned EMDR practitioner looking to deepen your understanding or someone newer to BLS who wants to build a stronger foundation.

BLS Is Not One Thing
One of the most common misconceptions about bilateral stimulation is that it’s a single, uniform tool. Tap left, tap right. Repeat. Done.
In reality, different forms of BLS — tactile (tapping or vibration), auditory (alternating tones), and visual (eye movements) — engage the brain through distinct pathways. And the speed and intensity of the stimulation matter just as much as the modality.
When delivered at slower speeds, bilateral stimulation tends to activate the parasympathetic nervous system — the “rest and digest” state. This can calm the body, reduce physiological arousal, and create the kind of regulated, open state that makes deep trauma processing possible.
At higher speeds or intensities, the effect can shift — sometimes toward activation rather than settling. For clients who are already on edge, this distinction isn’t academic. It can mean the difference between a productive session and one that leaves someone feeling flooded and destabilized.
Why Understanding BLS Matters Clinically
When therapists understand what BLS is doing neurologically, something shifts in how they use it. They stop applying it like a set protocol and start using it like a precision instrument.
Here’s what a deeper understanding unlocks:
- You can calibrate in real time. Rather than setting a speed and leaving it on autopilot, you can read your client’s nervous system responses — the subtle signs of overwhelm, the indicators of settling, the moments when processing has stalled — and adjust accordingly. Client feedback becomes data, not just conversation.
- You can match the modality to the moment. Tactile BLS (like wearable buzzers or tapping) may be especially grounding for clients who struggle to stay present. Auditory BLS can be powerful for clients who process more through sound and feeling. Visual BLS is familiar but not always optimal. Knowing when to switch can transform outcomes.
- You can use BLS outside of formal trauma processing. Bilateral stimulation’s regulatory effects don’t require a full EMDR protocol. Light, slow BLS can be used for nervous system regulation at the start or end of a session, as a tool to help clients tolerate difficult material, or even as a between-session resource clients can access on their own.
The Guest Who Actually Gets This
The conversation is led by Dr. Amy Serin, and if you haven’t come across her work yet, you’re in for something special.
Dr. Serin is an internationally recognized neuropsychologist and stress expert who has spent her career at the intersection of neuroscience, EMDR, and neuromodulation. She founded Serin Centers to bring together these approaches for healing across the lifespan — with children, adolescents, and adults alike.
What makes her uniquely qualified to talk about BLS isn’t just her academic background. She has published research specifically on the safety and effectiveness of tactile bilateral stimulation — including its use in underserved populations where access to traditional therapy is limited. She pioneered the Neurosomatic Reset Technique. She’s one of a small group of U.S. clinicians with protocols for inducing deep meditative states for trauma release without psychedelics or ketamine.
Her book The Stress Switch hit #1 in Preventative Medicine on Amazon. She’s won international awards for neuroscience stress wearables, including a Gold Edison Award, and has been featured in USA Today, NBC, Men’s Health, and Inc.
She knows what BLS is doing in the brain. And she’s going to tell you — in plain language, with clinical applicability, in a way that will make you want to go back to your next session with entirely fresh eyes.
It’s Free. No Catch.
The Trauma Therapist Institute offers these Clinical Conversations at no cost because they believe that learning and staying connected to the trauma-informed community shouldn’t require a credit card. There’s no upsell hiding behind the registration link. It’s just a really good conversation, offered as a gift to clinicians who are doing important work.
If you can’t make it live, the replay will be available for 7 days after the event — so you can watch (or rewatch) on your own schedule.

The Shift From “I Hope This Helps” to “I Know Why This Works”
There’s a certain kind of confidence that comes from truly understanding the tools you’re using. Not just knowing the protocol, but knowing the mechanism. Knowing why you’re choosing what you’re choosing. Being able to explain it to a curious client. Being able to adjust in real time when something isn’t landing.
That’s what this conversation is designed to give you. Not more information to add to a pile — but a shift in how you see and use something you’re already doing.
If BLS is part of your clinical toolkit, this is worth an hour of your time.
