We created a simple evolutionary system, sexyloop, on a deterministic ten-state five-neighbour cellular automaton (CA) where self-reproducing loops have the capability of sex. With this ability, the loops are capable of transferring genetic material into other loops. This work was based on Sayama's evoloop which was transformed by adding a new state and new(More)
—In this manuscript, we survey the new and exciting approach of Smartphone based robotics for research and education. The increases in the computational power and sensing of smartphones, plus the recent availability of interface boards, have made this trend popular across a wide range of enthusiasts. As an example, we show how we built an Android based(More)
The ability to fluidly divert attentional resources toward relevant information is critical for successful behavior in animals and may be applicable for the control of autonomous behavior. Humans, monkeys and rodents, possess a network of cholinergic neurons throughout the basal forebrain that project to the hippocampus and the cortex. Modulating the(More)
Game theory is commonly used to study social behavior in cooperative or competitive situations. One socioeconomic game, Stag Hunt, involves the trade-off between social and individual benefit by offering the option to hunt a low-payoff hare alone or a high-payoff stag cooperatively. Stag Hunt encourages the creation of social contracts as a result of the(More)
Neuromodulators such as dopamine (DA), serotonin (5-HT), and acetylcholine (ACh) are crucial to the representations of reward, cost, and attention respectively. Recent experiments suggest that the reward and cost of actions are also partially represented in orbitofrontal and anterior cingulate cortices in that order. Previous models of action selection with(More)
Humans and other terrestrial animals use vision to traverse novel cluttered environments with apparent ease. On one hand, although much is known about the behavioral dynamics of steering in humans, it remains unclear how relevant perceptual variables might be represented in the brain. On the other hand, although a wealth of data exists about the neural(More)
We created a spiking neural controller for an agent that could use two different types of information encoding strategies depending on the level of chemical concentration present in the environment. The first goal of this research was to create a simulated agent that could react and stay within a region where there were two different overlapping chemicals(More)
Learning to ignore irrelevant stimuli is essential to achieving efficient and fluid attention, and serves as the complement to increasing attention to relevant stimuli. The different cholinergic (ACh) subsystems within the basal forebrain regulate attention in distinct but complementary ways. ACh projections from the substantia innominata/nucleus basalis(More)
