What is an electroolfactogram (EOG)?
An EOG is a recording of the electrical responses of olfactory sensory neurons to odorant stimulation.
How is the EOG recorded?
The EOG is recorded using electrodes placed on the olfactory epithelium while odorants are delivered through a humidified air stream.
What are the main components of the EOG recording setup?
The setup includes a recording electrode, reference electrode, air delivery system, and a computer for data acquisition.
Why is humidity important in the EOG recording?
Humidity helps maintain the viability of the olfactory epithelium and ensures accurate responses to odorants.
What software is used for data analysis in EOG recordings?
XI graph software is typically used to control stimulation protocols and analyze EOG signals.
