Light-dependent magnetoreception in birds: increasing intensity of monochromatic light changes the nature of the response

• Roswitha Wiltschko, Katrin Stapput, H. Bischof, Wolfgang Wiltschko
• Frontiers in zoology
• 2007

BackgroundThe Radical Pair model proposes that magnetoreception is a light-dependent process. Under low monochromatic light from the short-wavelength part of the visual spectrum, migratory birds show… (More)

A stereotaxic atlas of the brain of the zebra finch, Taeniopygia guttata, with special emphasis on telencephalic visual and song system nuclei in transverse and sagittal sections. Bethesda (MD)

A stereotaxic headholder for small birds

• H. Bischof
• Brain Research Bulletin
• 1981

A Stereotaxic headholder especially designed for small birds is described. The major advantage of the holder is its easy handling when mounting the bird to the apparatus, and better access to the… (More)

Sexual imprinting leads to lateralized and non-lateralized expression of the immediate early gene zenk in the zebra finch brain

• Carsten Lieshoff, Jürgen Große-Ophoff, H. Bischof
• Behavioural Brain Research
• 2004

Sexual imprinting is an early learning process by which young birds acquire the features of a potential sexual partner. The physiological basis of this learning process is an irreversible reduction… (More)

Avian Ultraviolet/Violet Cones Identified as Probable Magnetoreceptors

• Christine Niessner, Susanne Denzau, +5 authors Roswitha Wiltschko
• PloS one
• 2011

BACKGROUND The Radical-Pair-Model postulates that the reception of magnetic compass directions in birds is based on spin-chemical reactions in specialized photopigments in the eye, with cryptochromes… (More)

Gaze Strategy in the Free Flying Zebra Finch (Taeniopygia guttata)

• Dennis Eckmeier, Bart R H Geurten, +4 authors H. Bischof
• PloS one
• 2008

Fast moving animals depend on cues derived from the optic flow on their retina. Optic flow from translational locomotion includes information about the three-dimensional composition of the… (More)

Adolescent social environment shapes sexual and aggressive behaviour of adult male zebra finches (Taeniopygia guttata)

• Tim Ruploh, H. Bischof, Nikolaus von Engelhardt
• Behavioral Ecology and Sociobiology
• 2012

Adolescence is the pivotal transitional phase during which animals become sexually and socially mature and acquire the skills to cope with a variety of environmental challenges on their own. We… (More)

Hippocampal activation of immediate early genes Zenk and c-Fos in zebra finches (Taeniopygia guttata) during learning and recall of a spatial memory task

• Uwe Mayer, Shigeru Watanabe, H. Bischof
• Neurobiology of Learning and Memory
• 2010

Zebra finches (Taeniopygia guttata) are able to learn the position of food by orienting on spatial cues in a 'dry water maze'. In the course of spatial learning, the hippocampus shows high expression… (More)

Oscillating magnetic field disrupts magnetic orientation in Zebra finches, Taeniopygia guttata

• Nina Keary, Tim Ruploh, +4 authors H. Bischof
• Frontiers in Zoology
• 2009

BackgroundZebra finches can be trained to use the geomagnetic field as a directional cue for short distance orientation. The physical mechanisms underlying the primary processes of magnetoreception… (More)

The use of the geomagnetic field for short distance orientation in zebra finches.

• Joe Voss, Nina Keary, H. Bischof
• Neuroreport
• 2007

Although the ability to use the Earth's magnetic field for long distance orientation and navigation has been demonstrated in many animals, the search for the appropriate receptor has not yet… (More)
