In this episode, Zane and Gopu unpack the fascinating overlap—and key differences—between neural engineering and neuroengineering.

They explore how neural engineering focuses on decoding and interfacing with the nervous system through technologies like brain-computer interfaces (BCIs), which are helping restore movement and communication for people with paralysis. The discussion highlights recent progress in BCIs, how close we are to seamless brain-controlled devices, and what the next decade of innovation might look like.

Then the conversation shifts toward neuroengineering, a subfield of tissue engineering aimed at creating engineered brain tissue in the lab. The hosts discuss how this research is advancing our understanding of brain repair, regeneration, and neurodegenerative diseases—and the ethical questions that come with growing functional brain-like tissues outside the body.

Together, they ask: Where do biology and technology meet—and where should we draw the line?

In our episode on addiction, we admitted we weren’t sure if marijuana was truly addictive. That question stuck with me—so I went back to the research.

In this bonus episode, Zane dives into what he found after reviewing two major studies: a 2024 Journal of Clinical Investigation review by Le Foll et al. and a 2025 JAMA Network Open paper by Gowin et al. The evidence? Cannabis can be addictive for some people, and heavy or frequent use is linked to measurable changes in brain circuits that regulate memory, motivation, and control.

We break down how THC affects the endocannabinoid system, why today’s high-potency products raise the risk of dependence, and what brain imaging is revealing about long-term cannabis use. Zane also highlights current treatments for Cannabis Use Disorder (CUD)—from behavioral therapies to experimental brain stimulation approaches like TMS.

This is the kind of journey we love—admitting what we don’t know, following the science, and bringing you along as we learn together.

Substance abuse and addiction affect everything from how we live to how we think about choice. But what is addiction, and how do scientists study it? In this episode, Gopu shares what he’s been learning as he steps into the field of addiction neuroscience. Together, we explore the prevalence of substance use, why research often focuses on drugs like MDMA, THC, amphetamines, and opioids, and why everyday behaviors like eating sugar or scrolling social media are harder to study.

We also touch on the opioid crisis, naloxone as an antidote for fentanyl, and the role astrocytes and dopamine may play in addiction pathways.

A casual between friends about the science of substance use, the questions researchers ask, and the early steps of a journey into addiction neurobiology.
