Anterior/posterior long axis specialization is thought to underlie the organization of the hippocampus. However it remains unclear whether antagonistic mechanisms differentially modulate processing of spatial information within the hippocampus. We used fMRI and a virtual reality 3D paradigm to study encoding and retrieval of spatial memory during active(More)

In this paper we describe a control methodology for the navigation of an autonomous lighter-than-air vehicle based on visual input. The control system consists in a Linear Quadratic Regulator (LQR) and a Linear Quadratic Gaussian observer (LQG). Due to non-linearities in the actuators and in the radio frequency control system, some non-linear control terms(More)
