Becoming the voice of trauma & pain

When we started Cacti, almost no one was connecting chronic pain to trauma and the emotional brain. We intend to lead that conversation — weekly, in writing and on screen.

Cacti in conversation

Podcast interviews about Cacti

A growing collection of conversations on Cacti, our science, and the intersection of trauma, mental health, and chronic pain.

A weekly essay on the intersection

We're launching a regular publication exploring PTSD and pain, the neuroscience of emotional processing, developmental trauma, psychedelics in pain research, and the emerging tools — from medicines to digital therapeutics — that could change how pain is treated.

Grounded in real science, written for real people. Subscribe to be among the first to read.

What we'll be writing about

A preview of the threads we'll follow each week.

Neuroscience

How trauma activates the pain circuitry

The mechanisms by which threat learning keeps the pain system switched on — and what turns it down.

Development

Why early childhood matters most

The science of critical periods, attachment, and why adversity early in life raises lifelong pain risk.

Emotion

The anterior cingulate cortex

How emotions are processed in brain regions woven directly into the experience of pain.

Body

The vagus nerve & safety

Autonomic balance, basal vagal tone, and the body's sense of threat versus safety.

Medicine

Psychedelics & neuroplasticity

What the research really shows about plasticity, pain, and the next generation of medicines.

Technology

Apps & digital therapeutics

CBT-based and pain-reprocessing apps — and the case for tools built for PTSD and pain together.

Coming next

A channel for the conversation

In time, we'll bring this intersection to video — interviewing researchers, clinicians, and patients on trauma, the brain, and pain. Our aim is to position Cacti as the place this conversation lives, and to make rigorous science genuinely accessible.
