Passive electroreception in aquatic mammals

Journal of Comparative Physiology A, 2012
Passive electroreception is a sensory modality in many aquatic vertebrates, predominantly fishes. Using passive electroreception, the animal can detect and analyze electric fields in its environment. Most electric fields in the environment are of biogenic origin, often produced by prey items.

Localization of electroreceptive function in rabbits

Physiology & Behavior, 2003
The detection process by which animals react to the presence of electromagnetic fields (EMFs) may be a form of sensory transduction. However, the anatomic location of signal transduction in most species is unknown. Attempts to solve this problem by applying local EMFs and registering the resulting changes in the electroencephalogram (EEG) have not ...

Electroreception in the Turkistan catfish

Experientia, 1984
The Turkistan catfish,Glyptosternum reticulatum, has highly sensitive electroreceptors (threshold voltage gradient 1 μV/cm) that detect a voltage drop across the skin. These electroreceptors were found to be sensitive to magnetic stimulation.

Electroreception in the catfish,Amiurus nebulosus

Experientia, 1968
Zwergwelse (Amiurus nebulosus) sind elektrisch sehr empfindlich. Geblendete Tiere sprechen, je nach der Stromstarke, auf schwache Strome ohne Dressur mit biologisch bedeutsamen Reaktionen an: Ausweichen oder Annahern und gegebenenfalls Schnappen. Auf Grund einseitiger Denervierungsversuche konnte festgestellt werden, dass die sehr zahlreichen ausseren ...

Convergent designs for electrogenesis and electroreception

Current Opinion in Neurobiology, 1995
New- and old-world tropical electric fish lack a common electrical ancestor, suggesting that the mechanisms of signal generation and recognition evolved independently in the two groups. Recent research on convergent designs for electrogenesis and electroreception has focused on the structure of electric organs, the neural circuitry controlling the ...

Anatomical Evidence of Electroreception in the Coelacanth (Latimeria chalumnae)

Anatomia, Histologia, Embryologia: Journal of Veterinary Medicine Series C, 1980
Serial sections of an immature female Latimeria brain were studied to describe the octavolateral area. Sections were stained with cresyl violet (for cell bodies) and with Kluver-Barrera method for myelinated fibers. The presence of a well-developed dorsal nucleus of the octavolateral area suggests that Latimeria probably possesses the electroceptive ...

Ontogeny of the Electroreceptive System of The Platypus.

Australian Mammalogy, 1998
A series of developmental stages of the platypus were examined in order to obtain an anatomical description of the development of the periphery of the electroreceptive system. Putative electroreceptors, composed of modified mucous glands, were observed to appear at I0 days post hatching (p.h.).

Central neurons involved in the electroreception of the catfishKryptopterus [PDF]

Journal of Comparative Physiology A, 1975
1. The catfishKryptopterus was stimulated with a.c.fields of various strengths and frequencies. 2. The responses of the afferent nerve fiber of the ampullary electroreceptors to these fields and the response of central units in the cerebellum to the same fields were measured and compared. 3.

Recent advances in the study of electroreception

Current Opinion in Neurobiology, 1991
Recent studies on electroreception in fish have focused on the structure and function of recurrent descending pathways, efference copy mechanisms, and multiple neuronal maps involved in the processing of sensory information. Studies on a neuronal oscillator have revealed that different neuronal inputs modulate the pattern of oscillations to produce ...

The future of research on electroreception and electrocommunication

Journal of Experimental Biology, 1999
ABSTRACT Beyond continuation of currently active areas, some less studied ones are selected for predictions of marked advance. (1) Most discoveries will be in cellular components and molecular mechanisms for different classes of receptor or central pathways. (2) More major taxa, possibly birds, reptiles or invertebrates, will be found to
