The following explanation has been generated automatically by AI and may contain errors.

The provided code is a computational model simulating the behavior of agents (which can be thought of as simplified organisms) navigating a spatial environment similar to the classic Morris Water Maze (MWM). This type of experiment is widely used in neuroscience to study spatial learning and memory, particularly the role of different brain regions like the hippocampus in these processes.

Biological Basis

Hippocampus and Striatum's Role in Spatial Navigation

Morris Water Maze Analogy

The custom environment, HexWaterMaze, represents a variant of the Morris Water Maze. In the biological experiment, rodents are placed in a tank filled with opaque water. They must find an escape platform using spatial cues. This code abstracts that concept into a grid-based environment with agents learning to locate platform positions through simulated episodes.

Learning and Memory Variables

Influence of Temperature and Reinforcement Learning

Overall, this code provides a controlled setting to simulate and study how different neural substrates contribute to learning and memory in spatial navigation, focusing primarily on the interactions and distinctions between the hippocampus and other brain regions like the striatum. The lesions simulate experimental manipulations seen in neuroscience to understand the distinct cognitive roles of these areas.
