Summary of "Role of the hippocampus in spatial memory in Japanese quail."

The Japanese quail is a powerful model to characterize behavioral, physiological, and neurobiological processes in Galliformes. Behavioral tests have already been adapted for quail to assess memory systems, but despite the pivotal role of the hippocampus in this cognitive process, its involvement in spatial memory has not been demonstrated in this species. In this study, lesions were created in the hippocampus of Japanese quail, and both lesioned and control quail were tested for spatial and cue-based learning performances. These hippocampal lesions specifically impacted spatial learning performance, but spared learning performance when birds could solve the task using their cue-based memory. These findings, thus, highlight that the hippocampus plays a crucial role and is essential for spatial declarative memory. Future studies could aim to elucidate the cellular or molecular mechanisms involved in this form of memory.

Activation of D1-like dopamine receptors is involved in the impairment of spatial memory in the offspring of morphine-abstinent rats.

Accumulating evidence suggests that epigenetic mechanisms play an essential role in the formation and maintenance of memory as well as addiction. In this study, we examined the role of D1-like dopamin...

Effect of enriched environment and predictable chronic stress on spatial memory in adolescent rats: predominant expression of BDNF, nNOS, and interestingly malondialdehyde in the right hippocampus.

Little is known about the mechanisms that promote divergence of function between left and right in the hippocampus, which is most affected by external factors and critical for spatial memory. We inves...
