Electric eels can incapacitate prey with an electric discharge, but the mechanism of the eel’s attack is unknown. Through a series of experiments, I show that eel high-voltage discharges can activate prey motor neurons, and hence muscles, allowing eels to remotely control their target. Eels prevent escape in free-swimming prey using high-frequency volleys to induce immobilizing whole-body muscle contraction (tetanus). Further, when prey are hidden, eels can emit periodic volleys of two or three… 

Electric Eels Concentrate Their Electric Field to Induce Involuntary Fatigue in Struggling Prey

Recent findings that show eel electric high-voltage discharges activate prey motor neuron efferents are extended and explain reports that human movement is ‘frozen' by eel discharges and shows the mechanism to resemble a law-enforcement Taser.

Electric Eels Wield a Functional Venom Analogue

The evolution of enough electrical power to remotely activate ion channels in prey efferents sets the stage for the selection of eel behaviors that functionally “poison” prey muscles.

Efficient high-voltage protection in the electric catfish

Both self-produced and external electric shocks that heavily affected control goldfish failed to evoke involuntary muscle contraction or to affect sensorimotor processing, and electric catfish are completely immune not only to their own high-voltage electrical shocks but also to external shocks delivered by a commercial electrofishing device.

Leaping eels electrify threats, supporting Humboldt’s account of a battle with horses

A defensive eel behavior is reported that supports the story of electric eels attacking horses that had been herded into a muddy pool during the dry season in 1800 and highlights sophisticated behaviors that have evolved in concert with the eel’s powerful electrical organs.

Electroreception, electrogenesis and electric signal evolution.

This review has two aims: to synthesise the knowledge of the functional biology and phylogenetic distribution of electroreception and electrogenesis in fishes, with a focus on freshwater taxa and on the proximate bases of EOD and electroreceptor diversity, and to describe the diversity, biogeography, ecology and electric signal diversity of the mormyroids and gymnotiforms.

A model for studying the energetics of sustained high frequency firing

It is suggested that EOD-related costs external to electrocytes (including packaging of synaptic transmitter) substantially exceed the direct cost of electrocyte ion homeostasis.

The third form electric organ discharge of electric eels

This work suggests that every form of EOD is generated by one electric organ independently and reveals the typical discharge order of the three electric organs, and presents the third form of independent EOD of electric eels: middle-voltage EOD.

Electric catfish hearts are not intrinsically immune to electric shocks.

It is discovered that, despite its immunity in vivo, the explanted heart of electric catfish can readily be activated by external electrical currents and is equally sensitive to electric shock-induced arrhythmias as similar-sized goldfish hearts.



Electric organ discharge (EOD) and prey capture behaviour in the electric eel, Electrophorus electricus

The prey capture behaviour and the pattern of the associated electric organ discharge (EOD) were studied in the electric eel, Electrophorus electricus and no evidence was found that the prey was detected by the low-voltage EOD.

The electric sense of sharks and rays.

The experiments described demonstrate clearly that the shark Scyliorhinus canicula and the ray Raja clavata make a biologically significant use of their electrical sensitivity and are justified in accrediting the animals with an electric sense and in designating the ampullae of Lorenzini as electroreceptors.

The purpose of this communication is to describe the historical steps by which fish electric organs were eventually determined to be modified motor endplates and therefore a plentiful source of

Firing patterns of motor units in normal rats

Recording for extended periods from single motor units in the fast extensor digitorum longus (edl) and the slow soleus (sol) muscle of freely moving adult rats yields information about firing rate, amount of use, modulation of muscle force and tonic and phasic behaviour for 16 motor units.

Effects of high-frequency stimulation and doublets on dynamic contractions in rat soleus muscle exposed to normal and high extracellular [K+]

Results indicate that stimulation with supratetanic frequencies can improve dynamic muscle contractility, but improvements are attenuated when muscles are exposed to high extracellular [K+].

Developmental data for this species support the view that, as in other weakly electric gymnotoids, a primitive larval electric organ probably precedes the adult structure, lending weight to published theories of an Electrophorus-like ancestor to the wekly electric fish.

The influence of a doublet of stimuli at the beginning of the tetanus on its time course.

The results show that slow units are characterized by better summation of their tension at the beginning of a tetanus, compared to fast units which showed greater sensitivity of the tension and the tetanus area to the doublet than fast units.

Genomic basis for the convergent evolution of electric organs

The results indicate that, despite millions of years of evolution and large differences in the morphology of electric organ cells, independent lineages have leveraged similar transcription factors and developmental and cellular pathways in the evolution of electric organs.

Doublet discharge stimulation increases sarcoplasmic reticulum Ca2+ release and improves performance during fatiguing contractions in mouse muscle fibres

Doublets are beneficial in that they improve contractile performance when added at any stage of strenuous activity, although the effect is largest in early fatigue stages.
