Spatial Learning and Memory Using a Radial Arm Maze with a Head-Mounted Display

Spatial memory in pigeons on a four-arm radial maze.

Spatial pattern learning in the radial arm maze.

Rats experienced a spatial pattern of baited and unbaited arms in an eight-arm radial maze. The spatial pattern remained constant over trials, but the spatial locations that were baited varied unpredictably. Although there was no evidence of control by the spatial pattern during free choice training trials, the rats' ability to locate baited arms in forced choice test trials was superior to tha...

Exercise influences spatial learning in the radial arm maze.

Previous studies indicate that the hippocampus is active during exercise, and that neurotrophin expression, receptor density, and survival of dentate gyrus granule cells in the hippocampus can be modified by moderate voluntary exercise. The present study was designed to test the consequences of voluntary exercise on a hippocampal-related behavior. Exercising and control rats were tested on the ...

Correlation between head direction cell activity and spatial behavior on a radial arm maze.

This study assessed the activity of head direction (HD) cells during performance of a spatial reference memory task on a radial arm maze. Rats were trained to select a maze arm located in a constant position in relation to a salient extramaze visual landmark. HD cell discharge properties remained relatively stable across task acquisition in most rats. Following acquisition, rotation of the land...

Nigella sativa Oil Enhances the Spatial Working Memory Performance of Rats on a Radial Arm Maze

Nigella sativa, an established historical and religion-based remedy for a wide range of health problems, is a herbal medicine known to have antioxidant and neuroprotective effects. This present study investigated the effect of Nigella sativa oil (NSO) administration on the spatial memory performance (SMP) of male adult rats using eight-arm radial arm maze (RAM). Twelve Sprague Dawley rats (7-9 ...
