Abstract :
Neurophysiological experiments in the hippocampal formation of echolocating bats have found grid cells (thought to be used for odometry) as in other mammals, but without continuous theta frequency oscillations (~8 Hz) prominent in other mammals. We describe a `theta-free´ model of grid cell property creation for echolocating bats that is amenable to VLSI implementation of hippocampal models of spatial navigation. We demonstrate a hybrid implementation of a 2-D model (microcontroller and neuromorphic VLSI) using recorded input from a sonar system.
