A Video Demonstration of Preserved Piloting by Scent Tracking but Impaired Dead Reckoning After Fimbria-Fornix Lesions in the Rat

Ian Q. Whishaw¹, Boguslaw P. Gorny¹

¹Department of Neuroscience, Canadian Centre for Behavioural Neuroscience, University of Lethbridge

In a piloting scent tracking task, the ability of the rats to return to a refuge with food using visual an odor trail or using dead reckoning in infrared light, the integrated record of previous movements, demonstrates that the hippocampus is necessary for dead reckoning.

The Ladder Rung Walking Task: A Scoring System and its Practical Application.

Gerlinde A. Metz¹, Ian Q. Whishaw¹

¹Canadian Centre for Behavioural Neuroscience, Department of Neuroscience, University of Lethbridge

The ladder rung walking task is a new test to assess skilled walking and measure both forelimb and hindlimb placing, stepping, and inter-limb co-ordination.

Frame-by-Frame Video Analysis of Idiosyncratic Reach-to-Grasp Movements in Humans

Jenni M. Karl¹, Jessica R. Kuntz², Layne A. Lenhart², Ian Q. Whishaw²

¹Department of Psychology, Thompson Rivers University, ²Department of Neuroscience, University of Lethbridge

This protocol describes how to use frame-by-frame video analysis to quantify idiosyncratic reach-to-grasp movements in humans. A comparative analysis of reaching in sighted versus unsighted healthy adults is used to demonstrate the technique, but the method can also be applied to the study of developmental and clinical populations.
