Abstract
We shall investigate how a nervous system reads the signals with which it encodes sensory stimuli. We shall examine two unique neurons, which receive sensory inputs in the locust brain and carry spike trains spikes to motor circuits in thoracic ganglia. The DCMD neuron produces trains of spikes that track object approaching a compound eye on a collision course, and we shall discover which parameters in a spike train are important for triggering behaviours such as escape jumping or pauses in flying. The DNI neuron receives information from the simple eyes. We shall study in DNI the transformation of graded potential input signals into spike trains, and subsequently how spike trains are decoded to graded potentials in flight motor neurons.
