Temporal Order Memory Task
Objective: To examine the role of the hippocampus in recognition memory tasks requiring animals to use recency information to discriminate when objects were encountered (temporal order memory)
This is a Temporal Order Memory Task protocol using rat as the model organism. The procedure involves 4 procedural steps, 1 materials. Extracted from a 2011 paper published in Journal of Neuroscience.

Confirm first
- Verify the animal model, intervention setup, and collection timepoints against the source paper.
- Check that every direct vendor link matches the exact specification your lab plans to run.

Lesion Surgery
Rats received bilateral cytotoxic lesions in the hippocampus or perirhinal or prefrontal cortex
Note: Bilateral lesions were created using cytotoxic methods

“Rats with bilateral cytotoxic lesions in the hippocampus or perirhinal or prefrontal cortex were tested”
Temporal Order Memory Task
Animals were tested on a spontaneous object recognition task requiring them to use recency information to discriminate when objects were encountered
Note: This task requires animals to make recognition memory judgments based on temporal or object recency component

“recency information (temporal order memory). Rats were then tested in a series of object recognition memory tasks”
Novel Object Preference Task
Animals were tested on a spontaneous object recognition task requiring them to use familiarity information
Note: Control task to assess familiarity-based recognition

“spontaneous object recognition tasks requiring the animals to make recognition memory judgments using familiarity (novel object preference)”
Object-in-Place Memory Task
Animals were tested on a spontaneous object recognition task requiring them to use object-place information
Note: Task assesses spatial location memory component
