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.

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...
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...
The objective of the current study was to assess the carcass traits and meat quality in three different Japanese quail strains. A total of 90 1-day-old Japanese quail chicks of three different strains...
On the basis of recent works demonstrating that environmental factors experienced by parents can affect their offspring, the present study was aimed at investigating whether the learning of a spatial ...
Absent in melanoma 2 (AIM2) senses damaged-associated molecular patterns (DAMPs) and recruits apoptosis speck-like protein (ASC) and caspase-1 to form a molecular platform for cerebral inflammation an...
Recent studies indicate that obese teenagers exhibit memory disturbances. Adolescence represents a crucial period in the development of the hippocampus and the amygdala, necessary for the ...
The purpose of this study is to examine how a part of the brain called the hippocampus contributes to memory changes that occur with aging and Alzheimer's disease (AD). Memory problems ar...
Stress and corticosteroid exposure are associated with changes in both the human and animal hippocampus. An extensive literature suggests that corticosteroid-induced changes in the hippoca...
Aims 1. To determine whether the 4 Mountains test of allocentric (i.e. viewpoint-independent) spatial memory, and tests of memory for a recent experience (e.g. watching a brief ...
The purpose of this study is to explore how the brain works during particular memory tasks in people with schizophrenia and healthy volunteers. Research has shown that patients with schiz...
Neurons in the ENTORHINAL CORTEX that project to the HIPPOCAMPUS. Grid cells and PLACE CELLS play a role in cognitive representation of spatial memory and navigation.
Memory related to spatial information.

Methods used to take into account and incorporate spatial autocorrelation and regional variation into regression analysis models of data that has spatial dependency, and also to provide information on the spatial relationships among the variables.
