Eva Siehmann won the Lorenz-Wegen award for best thesis at her university, Westfälischen Hochschule. She did her thesis project at the LIMBS lab during Spring-Summer 2013.
In her thesis, Eva Siehmann focused on decoding the neural circuitry for extracting features called ‘envelopes’, which are present in a lot of sensory signals. Her work was specifically on envelope extraction in the electrosensory system of weakly electric fish. Eva attempted to deduce, through a task-level experiment, whether the nonlinear mechanism in question is half-wave or full-wave rectifier with a low-pass filter following it.
