Active Place Avoidance

Price range: $13,990.00 through $14,990.00
The APA is a circular metal arena featuring a shock grid beneath a rotating platform. Rodents are given the opportunity to explore the arena, using visual cues to avoid a designated prohibited sector. If the rodent enters this restricted area, it receives a mild shock as a form of punishment. Passive avoidance is measured when the arena is stationary, while active avoidance is assessed when the arena is in motion. The Active Place Avoidance Arena is designed to evaluate spatial navigation and memory in rodents. The rotating platform complicates the task by requiring continuous movement to avoid the shock zone, thereby eliminating simple associative learning. The dry surface of the arena makes it particularly suitable for studying spatial navigation in young rodents. This tool is effective for examining the impact of brain lesions, pharmacological treatments, and neurological disorders on spatial learning and memory. MazeEngineers provides the Active Place Avoidance apparatus for these studies.

  • The Active Place Avoidance Arena is used to assess spatial navigation and memory in rodents.
  • The rotating arena used in the Active Place Avoidance task eliminates the use of simple associations and forces the subject to keep moving to avoid the shock area.
  • The shock sector of the arena is defined by distal room cues.
  • The dry-arena makes Active Place Avoidance task suitable for evaluating spatial navigation performances of weanling rodents.
  • Active Place Avoidance can be used as an effective tool for investigating the effects of brain lesions, pharmacological manipulations, and diseases on spatial learning and memory.
