“…By contrast, the control chicks that oriented by a local feature of the feeder do not need to perform relational computations and should therefore not rely on hippocampal involvement. However, we should note that a functional hypothesis of “relational computations” for the hippocampus has been developed from research in mammals, and it has been argued that the avian HF may be a more dedicated spatial processing structure, whose functional properties resemble more the idealized cognitive map of O'Keefe and Nadel (1978; see Coppola et al, ).…”

We employed a standard reference memory task to study the involvement of the hippocampal formation (HF) of domestic chicks that used the boundary geometry of a test environment to orient to and locate a reward. Using the immediate early gene product c-Fos as a neuronal activity marker, we found enhanced HF activation in chicks that learned to locate rewarded corners using the shape of a rectangular arena compared to chicks trained to solve the task by discriminating local features in a square-shaped arena. We also analyzed neuronal activity in the medial part of the medial striatum (mMSt). Surprisingly, in mMSt we observed a reverse pattern, with higher activity in the chicks that were trained to locate the goal by local features. Our results identify two seemingly parallel, memory systems in chicks, with HF central to the processing of spatial-geometrical information and mMSt important in supporting local feature discrimination.

“…In contrast, accumulating evidence suggests that the avian HF may be surprisingly dedicated to spatial cognition (Sherry and Vaccarino, ; Hampton and Shettleworth, ,; Colombo et al, ; Bingman et al, ; Papadimitriou and Wynne, ; Shiflett et al, ; Strasser et al, ; Pearce et al, ; Bischof et al, ; Mayer and Bischof, ; Coppola et al, ). For example, HF lesions in pigeons do not impair paired‐associate learning (Bingman et al, ), transitive inference (Strasser et al, ; but see below) or negative patterning (Papadimitriou and Wynne, ), learning phenomena that are impaired in hippocampal‐lesioned rats (Rudy and Sutherland, ; Bunsey and Eichenbaum, ).…”

For more than 30 years, a growing number of researchers have been attracted to the challenge of understanding the neurobiological organization of the avian hippocampal formation (HF) and its relationship to the remarkable spatial cognitive abilities of birds. In this selective review, we highlight recent anatomical and developmental findings that reveal a HF design that defies any simple comparison to the mammalian hippocampus and leaves unanswered the seemingly enduring question of whether a dentate gyrus homologue is to be found in HF. From a functional perspective, we highlight the recent discoveries that implicate HF in the use of space for memory pattern segregation and continued interest in the role HF neurogenesis may play in supporting memory function and its relationship to memory decline in aging birds. We also summarize data that nurture a fundamental reinterpretation of the role of HF in spatial cognition by suggesting HF involvement in spatial perception antecedent to any memory formation. Given the disproportionate adaptive significance of space for birds, which has led to the evolution of their exceptional navigational and memory abilities, there is little doubt that the avian HF will continue to provide important and unexpected insights into the neural basis of spatial cognition.

“…Due to the importance of the avian hippocampus in cognition and its dedicated role in spatial memory (Coppola et al 2014;Herold et al 2015), we hypothesized that time-of-day information would be more strongly associated with spatial, location-based cues than with nonspatial, features-based color cues. In this study, we trained one group of pigeons to use time of day to discriminate among alternative spatial choices and another group to discriminate among alternative feature (color) choices.…”

This study examined time‐of‐day associative learning to either spatial or feature information in homing pigeons in an open‐field, laboratory setting. Homing pigeons are well known for their navigational abilities and generally have been shown to rely more heavily on spatial than nonspatial cues in recognizing a goal. However, during goal localization, homing pigeons also successfully use nonspatial, feature information. Homing pigeons were divided into two groups and were trained to locate two time‐of‐day dependent, food reward sites using either discriminative spatial or feature information. Because of the importance of the hippocampus in controlling avian memory, we hypothesized that homing pigeons trained with spatial cues would be superior in learning the time‐of‐day discrimination compared to the pigeons trained with feature cues. Indeed, homing pigeons that were trained with spatial information outperformed the pigeons trained with feature information in learning the time‐of‐day discrimination task.
