TY - CONF T1 - The role of lateral inhibition in the sensory processing in a simulated spiking neural controller for a robot T2 - Proc. 2009 IEEE Symposium on Artificial Life (ALIFE 2009) Y1 - 2009 A1 - David Bowes A1 - Roderick G Adams A1 - Lola Cañamero A1 - Volker Steuber A1 - Davey, Neil AB - Visual adaptation is the process that allows animals to be able to see over a wide range of light levels. This is achieved partially by lateral inhibition in the retina which compensates for low/high light levels. Neural controllers which cause robots to turn away from or towards light tend to work in a limited range of light conditions. In real environments, the light conditions can vary greatly reducing the effectiveness of the robot. Our solution for a simple Braitenberg vehicle is to add a single inhibitory neuron which laterally inhibits the output to the robot motors. This solution has additionally reduced the computational complexity of our simple neuron allowing for a greater number of neurons to be simulated with a fixed set of resources.

It also investigates two models of receptor response to stimulus levels. The results show that exponential decay of ions across the soma and of a receptor response function where intensity is proportional to intensity is the best combination for dark seeking behaviour.
