Coding and processing of electrosensory information in gymnotiform fish [PDF]

Journal of Experimental Biology, 1989
ABSTRACT Studies of the electrosensory system of gymnotiform fish have revealed principles of neuronal coding and processing of information which also character-ize more advanced systems, such as vision and audition in higher vertebrates.

Neuromodulation of early electrosensory processing in gymnotiform weakly electric fish [PDF]

Journal of Experimental Biology, 2013
Summary Sensory neurons continually adapt their processing properties in response to changes in the sensory environment or the brain's internal state. Neuromodulators are thought to mediate such adaptation through a variety of receptors and their action has been implicated in processes such as attention, learning and memory, aggression ...

Regulation and modulation of electric waveforms in gymnotiform electric fish [PDF]

Journal of Comparative Physiology A, 2006
Weakly electric gymnotiform fish specialize in the regulation and modulation of the action potentials that make up their multi-purpose electric signals. To produce communication signals, gymnotiform fish modulate the waveforms of their electric organ discharges (EODs) over timescales spanning ten orders of magnitude within the animal's life cycle ...

The complete mitochondrial genome of the Chinese hook snout carp Opsariichthys bidens (Actinopterygii : Cyprinifonnes) and an altemative pattem of mitogenomic evolution in vertebrate [PDF]

, 2007
The complete mitochondrial genome sequence of the Chinese hook snout carp, Opsariichthys bidens, was newly determined using the long and accurate polymerase chain reaction method.

Electric imaging through evolution, a modeling study of commonalities and differences. [PDF]

PLoS Computational Biology, 2014
Modeling the electric field and images in electric fish contributes to a better understanding of the pre-receptor conditioning of electric images. Although the boundary element method has been very successful for calculating images and fields, complex ...

Submicrosecond pacemaker precision is behaviorally modulated: The gymnotiform electromotor pathway [PDF]

Proceedings of the National Academy of Sciences, 1998
What are the limits and modulators of neural precision? We address this question in the most regular biological oscillator known, the electric organ command nucleus in the brainstem of wave-type gymnotiform fish. These fish produce an oscillating electric field, the electric organ discharge (EOD), used in electrolocation and communication.

Visual and Electrosensory Circuits of the Diencephalon in Mormyrids [PDF]

, 1990
Mormyrids are one of two groups of teleost fishes known to have evolved electroreception, and the concomitant neuroanatomical changes have confounded the interpretation of many of their brain areas in a comparative context, e.g., the diencephalon, where ...

Genome Expansion of ZPB1(a) and ZPC1(a) in Basal Species or Liver Expression of ZPB1a and ZPC1aa in Advanced Species, Two Different Strategies to Ensure Sufficient ZP Synthesis in Teleosts

Integrative Zoology, EarlyView.
We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...

Fish fauna of headwater streams that cross the Atlantic Forest of south São Paulo state [PDF]

Check List, 2012
The fishes of the present study were collected in the headwater streams of the Sorocaba, Paranapanema and Ribeira de Iguape river basins during the dry period in 2010. A total of 2892 fishes, grouped in 53 species, were captured.
