BME 4900 FINAL REPORT 9Team 82.2 Optimal Design2.2.1 ObjectiveThe objective of this final design is to provide a cheap, cost-effective system thatis capable of mimicking the physiological properties of the horizontal saccade controllerof the brain. In essence, the complete system consists of a series of subsystems designedto imitate the behavior of actual neuronal populations in the horizontal saccadecontroller (see Fig. 5).Figure 5. The neural network for the horizontal saccade generation is shown. Times zero and Trepresent saccade initiation and termination, respectively.

Below, in Fig. 6, a diagram of thesecomponents and their interrelations can be found.Action PotentialsFrom Pre-SynapticNeuronsSynaptic Component(Voltage à CurrentConverter)Post-SynapticDendriteComponentPost-Synaptic AxonComponentPost-Synaptic SomaComponentAction Potentials toFollowing Post-Synaptic NeuronsFigure 6. Flow chart describing the propagation and interpretation of signals through theindividual neuron populations.Following this general pattern, each neuron can be modified from a series of“stock” components developed to provide readily available machinery that, as a whole,can provide acceptable descriptions of all neural populations in the horizontal saccadesystem. The first of these components is the synapse, which is responsible for passingthe output of a pre-synaptic neuron to the input mechanisms of the following postsynapticneuron. Here, the voltage action potential signal is converted to a current pulsewhich can be used to excite the following neuron in a specific manner. This currentpulse passes through the dendritic compartments which function as a filter to provide
