Question

The Figure below depicts a map of the firing pattems of four cells recorded from a rat's Hippocampus as the rat traversed the maze. Each circle depicts the location of a

cell firing and the color of the circle indicates which of the four cells fired. Based on this figure, it would be reasonable to conclude that

A.Cells 1 and 4 are recorded from Ventral Hippocampus; Cells 2 and 3 are recorded from Dorsal Hippocampus
B. Cells 1 and 2 are recorded from Dorsal Hippocampus; Cells 3 and 4 are recorded from Ventral Hippocampus
C.Cells 1 and 4 are recorded from Dorsal Hippocampus; Cells 2 and 3 are recorded from Ventral Hippocampus
D.Cells 1 and 2 are recorded from Ventral Hippocampus; Cells 3 and 4 are recorded from Dorsal Hippocampus

Answer 1

Based on the relationship between hippocampal regions and their functions, it's suggested that Cells 1 and 2, showing spatial firing patterns, are from the Dorsal Hippocampus while Cells 3 and 4 are from the Ventral Hippocampus, aligning with option B being the correct answer.

Step-by-step explanation:

The hippocampus is a brain region involved in various functions, including memory processing, specifically declarative, episodic, and spatial memory. Given the question's details regarding cells firing in a rat's hippocampus, it suggests the firing patterns of neuronal cells are unique to their location within the hippocampus.

With dorsal hippocampal cells typically associating more with spatial memory, and the ventral hippocampal cells more with emotional contexts, it may be inferred that cells that show specific spatial firing patterns (like those active when traversing a maze) would belong to the dorsal hippocampus. Hence, if cells 1 and 2 demonstrate such spatial patterns, while cells 3 and 4 do not, it would suggest that Cells 1 and 2 are recorded from Dorsal Hippocampus; Cells 3 and 4 are recorded from Ventral Hippocampus, making option B the most likely correct answer.
