Physiological positional nystagmus observed during electronystagmography (ENG) typically follows a specific pattern depending on the position of the head. When a person is in a supine position and the head is turned to one side, the nystagmus will generally beat towards the lower ear (the ear that is lower in relation to the ground).

1. **Right Ear Down**: If the right ear is down, the nystagmus typically beats towards the right ear.
2. **Left Ear Down**: Conversely, if the left ear is down, the nystagmus will beat towards the left ear.

This type of nystagmus is considered physiological and is usually short-lived, resolving within a few seconds. It is important to differentiate physiological nystagmus from pathological nystagmus, which could indicate a vestibular disorder.
