Summary of intracellular cation dynamics following odor presentation in neurons and support cells.
| Cation (reporter) | ||
|---|---|---|
| Cell type (cell-specific driver) | Ca2+ (GCaMP6f) | K+ (GINKO1) |
| Orco+ OSNs (Orco-GAL4) | INCREASE | DECREASE* |
| Tormogen cells (ASE5-GAL4) | INCREASE (in subpopulation) | NO CHANGE |
| Thecogen cells (nompA-GAL4) | NO CHANGE | INCREASE* |
Tormogen cells respond to VUAA1 application by influx of cytoplasmic Ca2+ while thecogen cells exhibit a cytoplasmic K+ influx. Asterisk (*) denotes a K+ buffering mechanism coupling OSNs and their thecogen cell.
