Recollection of What-where-which Memory in Degus (octodon Degus)
To examine if a feature of episodic-like memory reported in rats is shared with other species, we investigated whether degus would form an integrated memory of object (what), place (where), and context (which). We used two E-shaped mazes with different contexts regarding the wall and the floor. Degus were entered into the middle arm and first explored the maze with two trial-unique objects plac...
متن کاملWheel-running and rest activity pattern interaction in two octodontids (Octodon degus, Octodon bridgesi).
Wheel-running and other non-photic stimuli influence the rest-activity pattern of diurnal and nocturnal mammals. A day to night inversion of phase preference of activity was described among Octodon degus, when exposed to ad-libitum wheel running. We have studied the rest-activity pattern response in presence of ad libitum wheel-running in wild-captured male individuals from two species of genus...
متن کاملRetinal aging in the diurnal Chilean rodent (Octodon degus): histological, ultrastructural and neurochemical alterations of the vertical information processing pathway
The retina is sensitive to age-dependent degeneration. To find suitable animal models to understand and map this process has particular importance. The degu (Octodon degus) is a diurnal rodent with dichromatic color vision. Its retinal structure is similar to that in humans in many respects, therefore, it is well suited to study retinal aging. Histological, cell type-specific and ultrastructura...
متن کاملRetinal projection to the dorsal raphe nucleus in the Chilean degus (Octodon degus).
A substantial projection from the retina to the dorsal raphe nucleus (DRN) has been demonstrated in the Chilean degus, a diurnal/crepuscular hystricomorph rodent. Following intraocular injection of cholera toxin subunit B (CTB), immunocytochemically labeled CTB-positive axons and terminals were observed in all major retinorecipient nuclei as well as in the DRN and periaqueductal gray (PAG) of t...
متن کاملRevisiting rodent models: Octodon degus as Alzheimer’s disease model?
Alzheimer's disease primarily occurs as sporadic disease and is accompanied with vast socio-economic problems. The mandatory basic research relies on robust and reliable disease models to overcome increasing incidence and emerging social challenges. Rodent models are most efficient, versatile, and predominantly used in research. However, only highly artificial and mostly genetically modified mo...
