RatSLAM is a navigation system based on the neural processes underlying navigation in the rodent brain, capable of operating with low resolution monocular image data. Seminal experiments using RatSLAM include mapping an entire suburb with a web camera and a long term robot delivery trial. This paper describes OpenRatSLAM, an open-source version of RatSLAM(More)
OBJECTIVE Surface magnetic resonance imaging (MRI) for aortic plaque assessment is limited by the trade-off between penetration depth and signal-to-noise ratio (SNR). For imaging the deep seated aorta, a combined surface and transesophageal MRI (TEMRI) technique was developed 1) to determine the individual contribution of TEMRI and surface coils to the(More)
In this paper we describe a spiking neural circuit inspired by the pyramidalinterneuron network gamma (PING) circuit modeled by Whittington and colleagues [1]. The spiking network controls a rat animat – a rodent-inspired robot that can autonomously explore and map its environment. We demonstrate how the neural controller directs the rat animat‟s movement(More)
BACKGROUND A computer-based learning experience was developed using cognitive flexibility theory to overcome the pitfalls often encountered in existing medical education. An earlier study (not published) showed significant pretest-posttest increase in scores, as well as a significant positive correlation between choosing to complete the module individually(More)
Previous studies have shown how Lingodroids, language learning mobile robots, learn terms for space and time, connecting their personal maps of the world to a publically shared language. One caveat of previous studies was that the robots shared the same cognitive architecture, identical in all respects from sensors to mapping systems. In this paper we(More)
For humans and robots to communicate using natural language it is necessary for the robots to develop concepts and associated terms that correspond to the human use of words. Time and space are foundational concepts in human language, and to develop a set of words that correspond to human notions of time and space, it is necessary to take into account the(More)
