A Stereotaxic Atlas Of The Brain Of The Zebra Finch, Taeniopygia Guttata
Afferent connections of the ectostriatum and visual wulst in the zebra finch (Taeniopygia guttata castanotis Gould) — an HRP study
Afferent connections of the two main areas in the telencephalon, the visual wulst and the ectostriatum, were traced in the zebra finch by injection of horseradish peroxidase and staining with… Expand
GABAergic inputs to the nucleus rotundus (pulvinar inferior) of the pigeon (Columba livia)
The avian nucleus rotundus, a nucleus that appears to be homologous to the inferior/caudal pulvinar of mammals, is the major target of an ascending retino‐tecto‐thalamic pathway. Further… Expand
The use of the geomagnetic field for short distance orientation in zebra finches
TLDR
This work successfully trained nonmigratory zebra finches in a four-choice food-search task to use the natural magnetic field as well as an experimentally shifted field for short distance orientation, supporting the view that magnetic field perception may be a sense existing in all bird species. Expand
Avian Ultraviolet/Violet Cones Identified as Probable Magnetoreceptors
TLDR
The findings, identifying the UV/V-cones as probable magnetoreceptors, support the assumption that Cry1a is indeed the receptor molecule mediating information on magnetic directions, and provide the Radical-Pair-Model with a profound histological background. Expand
On the structure and function of the tectofugal visual pathway in laterally eyed birds.
TLDR
Evidence is provided that the tectofugal pathway serves both functions to localize an object and to guide the fixation movement. Expand
Oscillating magnetic field disrupts magnetic orientation in Zebra finches, Taeniopygia guttata
TLDR
Zebra finches use a receptor that bases on radical pair processes for sensing the direction of the earth magnetic field in this short distance orientation behavior, and application of such oscillating fields in behavioral experiments can be used as a diagnostic tool to decide between the two alternatives. Expand
Hippocampal activation of immediate early genes Zenk and c-Fos in zebra finches (Taeniopygia guttata) during learning and recall of a spatial memory task
TLDR
The results show that the avian hippocampus is also active during recall of a learned spatial task, but the activation is significantly lower than in animals learning actually. Expand
Responses to mirror-image stimulation in jungle crows (Corvus macrorhynchos)
Abstract Four jungle crows (Corvus macrorhynchos) were exposed to a mirror placed either vertically or horizontally. The most frequently observed behaviors were pecking at the mirror and wing… Expand
Sexual imprinting leads to lateralized and non-lateralized expression of the immediate early gene zenk in the zebra finch brain
TLDR
The first exposure to a female after an isolation period enhances zenk expression in a variety of brain areas including LNH, MNH, and optic tectum, and this adds to recent results which also support the idea of a lateralized organization of the avian visual system. Expand
