An Alternative Maze to Assess Novel Object Recognition in Mice
[Abstract] The novel object recognition (NOR) task is a behavioral test commonly used to evaluate episodic-like declarative memory and it relies on the innate tendency of rodents to explore novelty. Here we present a maze used to evaluate NOR memory in mice that reduces the time of the assay while improving reliability of the measurements by increasing the ...
Implanting and Recycling Neuropixels Probes for Recordings in Freely Moving Mice
[Abstract] Recording neural activity in unrestricted animals is necessary to unravel the neural basis of ethological behaviors. Recently, Neuropixels probes have made important strides in improving yield and lowering noise, but have limited use cases in freely moving animals. Although there are a number of studies demonstrating the use of these probes in ...

[Abstract] The Displaced Object Recognition (DOR) task, sometimes called the Novel Object Location task, assesses spatial recognition memory without navigational demands, explicit instruction, or the need for multiple days of training. This memory task has two phases. First, the subject is familiarized to an open arena with two objects and is allowed to ...
A Modified Barnes Maze for Juvenile Rats
[Abstract] To better understand neural codes for spatial navigation and to address cognitive development questions, the neurobiology of postnatal hippocampal development is receiving increased attention. While the Morris Water Maze is the gold standard for assessing hippocampal integrity, potential confounds can be difficult to control for in juvenile ...

[Abstract] Behavioural tests based on the spontaneous recognition paradigm have been used extensively for examining the memory capacity of rodents. By exploiting their innate preference to investigate novel stimuli, inferences can be drawn about the perceived familiarity of encountered objects. Olfaction is the dominant sense used by mice to navigate their ...

[Abstract] The Classic Labyrinth Test (CLT) is a simple way to evaluate behaviors in rodents such as learning ability, memory, and anxiety. The protocol presented here describes the procedure for use with rats, but the protocol can also be adapted for use in mice if a smaller device is used. In short, the CLT uses a square-shaped maze with a starting point ...
