Abstract We will address the effect of different intervals (on/off) of artificial light in the electric organ discharge patterns of Gymnotus carapo fish during electrolocalization and electrocommunication activities. We will choose some of the patterns with low probability and use them to control the light automatically. A computer with analog to digital and digital to analog interfaces (controled by a home made dynamic clamp protocol) will detect the fish firing patterns in real time and compare them to the chosen ones, generating an output signal to turn the light on/off based in those patterns. In such conditions we will be able to infer if the distribution of patterns change when the fish controls its own light, suggesting some learning capability. The student will implement all modifications needed in the experimental apparatus and will also develop programs for data analisys. | |
