Simple models of bursting and non-bursting P-type electroreceptors
Weakly electric "sh use phase and amplitude modulations of their electric organ discharge to communicate and to capture prey (electrolocation). P-type electroreceptors, also known as probability coders, on their skin can detect extremely weak signals. We analyse baseline "ring characteristics of these receptors from experimental data, and present mathematical models for the "ring activity of bo...
متن کاملGhostbursting in sensory cells of electric fish
We give an overview of the analysis of a new type of bursting (“ghostbursting”) seen in pyramidal cells of weakly electric fish. We start with the experimental observations and characterization of the bursting, describe a compartmental model of a pyramidal cell that undergoes ghostbursting and the development of a simplified yet realistic conductance–based model of this cell. This model then mo...
متن کاملMuscarinic receptors control frequency tuning through the downregulation of an A-type potassium current.
The functional role of cholinergic input in the modulation of sensory responses was studied using a combination of in vivo and in vitro electrophysiology supplemented by mathematical modeling. The electrosensory system of weakly electric fish recognizes different environmental stimuli by their unique alteration of a self-generated electric field. Variations in the patterns of stimuli are primar...

متن کاملDelay-Dependent Response in Weakly Electric Fish under Closed-Loop Pulse Stimulation
In this paper, we apply a real time activity-dependent protocol to study how freely swimming weakly electric fish produce and process the timing of their own electric signals. Specifically, we address this study in the elephant fish, Gnathonemus petersii, an animal that uses weak discharges to locate obstacles or food while navigating, as well as for electro-communication with conspecifics. To ...
