Delayed-matching-to-place Task in a Dry Maze to Measure Spatial Working Memory in Mice
Authors:  Xi Feng, Karen Krukowski, Timothy Jopson and Susanna Rosi, date: 07/05/2017, view: 731, Q&A: 0
The delayed-matching-to-place (DMP) dry maze test is a variant of DMP water maze (Steele and Morris, 1999; Faizi et al., 2012) which measures spatial working/episodic-like learning and memory that depends on both hippocampal and cortical ...

Thinned-skulled Cranial Window Preparation (Mice)
Authors:  Lifeng Zhang, Bo Liang, Yun Li and Da-Ting Lin, date: 03/05/2017, view: 1209, Q&A: 0
Imaging structural plasticity or activity of neurons in the brain circuit will facilitate understanding the neural mechanisms underlying animal behavior. Here we describe a modified procedure, the polished and reinforced thinned-skull cranial window ...

Sucrose Preference Test to Measure Anhedonic Behaviour in Mice
Authors:  Tsvetan Serchov, Dietrich van Calker and Knut Biber, date: 10/05/2016, view: 3410, Q&A: 0
The sucrose preference test (SPT) is a reward-based test, used as in indicator of anhedonia. Anhedonia, or the decreased ability to experience pleasure, represents one of the core symptoms of depression. Rodents are born with an interest in sweet ...

Locomotor Assay in Drosophila melanogaster
Authors:  Qingqing Liu, Jingsong Tian, Xing Yang, Yan Li and Aike Guo, date: 05/20/2017, view: 917, Q&A: 0
This protocol describes a simple locomotor assay in Drosophila melanogaster. In brief, the locomotor of each single fly in the culture dish is recorded by a web camera. The moving time, walking length, speed and the locomotor trails of the ...
