You might even get into the world of microfabrication to create tiny devices that can interact with individual neurons.

Biomedical engineering often plays a significant role. This is where you bring in the biological side, the interface between the engineered device and the biological system. You'll learn about biocompatibility, which is how the materials and devices interact with the body. Another focus will be on the biophysics of neural systems. And if you want to get into advanced stuff, computer science can be very useful for creating computational models, analyzing data, and developing algorithms for neural interfaces. With this you can analyze the activity of neurons in the brain, simulate neural circuits, and develop machine-learning algorithms to decode brain signals or control prosthetic devices.

Now, let's talk about some of the techniques used in the lab. Patch-clamp electrophysiology is a workhorse technique, allowing scientists to study the activity of individual ion channels in neurons. You'll be able to record the tiny currents flowing through these channels and see how drugs or other factors affect their function. Electrophysiology includes techniques like extracellular recording, where you measure the electrical activity of neurons from outside the cell. This method is often used to study the activity of large populations of neurons. Finally, neuroimaging techniques such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) provide a way to visualize brain activity. These methods can be combined with other techniques to get a more complete picture of what's happening in the brain. So basically, there are a lot of ways to get your hands dirty in this field!
