A model for transforming egocentric views into goal‐directed behavior

Neurons in the rat postrhinal cortex respond to the egocentric bearing and distance of boundaries in enclosed spaces.

• The response of neurons is associated with the geometric center of an enclosed space.
• This signal may relate to visual perception of motion parallax along boundaries.
• A known behavioral response is the centering response, where animals navigate towards the center based on boundary parallax.
• Incorporating an allocentric head direction signal could allow for navigation across two-dimensional space.
• The proposed model suggests that this neural signal supports goal-directed navigation through projections to the dorsomedial striatum.
• A straightforward code for navigational variables may transform sensory information into appropriate motor outputs.
