UT Southwestern Medical Center

UTSW researchers used a technique called optogenetic circuit mapping in which they inserted a gene into targeted neurons, allowing their activity to be controlled by light. By stimulating neurons that deliver inputs to the HVC, an area of the avian brain involved in birdsongs, then measuring the electrical activity of outputting neurons, the team could see which neurons communicated with one another.

These 3D models illustrate the study's findings. The top left image shows a circular coil used for magnetic seizure therapy (MST), while the top right image shows unilateral electrode placement for electroconvulsive therapy (ECT). The bottom row displays simulated electric field distribution in the brain during stimulation for each method. Warmer colors (red) indicate stronger electric fields, while cooler colors (blue) represent weaker fields, highlighting differences in how each technique interacts with brain regions.
