Influence Of Anterior Thalamic Inactivation On The Retrieval Of Spatial Reference Memory And Working Memory In The Radial Arm Maze, Ryan E. Harvey
Influence Of Anterior Thalamic Inactivation On The Retrieval Of Spatial Reference Memory And Working Memory In The Radial Arm Maze, Ryan E. Harvey
Psychology ETDs
Previous studies have shown that the anterior thalamic nuclei (ATN) contain a large population of head direction cells, which fire as a function of an animal’s directional orientation in an environment, thereby providing a compass-like representation guiding navigation. Recent work has suggested that directional orientation information stemming from the ATN is critical for the generation of hippocampal and parahippocampal spatial representations, and may contribute to the establishment of unique spatial representations in radially oriented tasks such as the radial arm maze. While studies have confirmed that ATN lesions impair the acquisition of new spatial information in variants of the radial …
