Neuroethology of Social Attention in Primates
<p>To solicit the attention or determine the intentions of another, we use our eyes. While many animals appear to use eyes as an important behavioral cue, for humans, these cues are especially critical. The power of the eyes to attract and direct attention shapes human behavior from an early age …

A Neuroethology Approach For Insect Senses And Behavior
Neuroethology is the study of neural basis of natural behavior. I studied learning using sound as a cue in fruit flies and made recordings from the Johnston's organ (JO), I also investigated associative learning in mosquitoes. Finally, I studied Salticid (jumping) spiders to investigate the neural …

Electrophysiology, agent-based modeling and inverse optimal control applications in neuroethology
Decision-making is based on the integration of sensory information, motivational states and memory, from which assessment of outcomes and optimal action selection emerge. In foraging, animals tend to make decisions that reconcile two core goals: energy maximization and time minimization. The …

Eight Legs And A Brain: Locomotor Mimicry Of Ants And Neuroethology Of Jumping Spiders
This thesis explores the ecology, behavior, and sensory neurobiology of jumping spiders (Araneae: Salticidae). The first section (Chapters 1 and 2) investigates antmimicry by the jumping spider Myrmarachne formicaria. The second section (Chapter 3) takes a neuroethological approach to sound …

The Computational Neuroethology of Weakly Electric Fish: Body Modeling, Motion Analysis, and Sensory Signal Estimation
Animals actively influence the content and quality of sensory information they acquire through the positioning of peripheral sensory surfaces. Investigation of how the body and brain work together for sensory acquisition is hindered by (1) the limited number of techniques for tracking sensory …

Aversive Olfactory Imprinting in Caenorhabditis Elegans
… memory (Chapter 4). Combining classical neuroethology, molecular genetics, and functional imaging, I have mapped distinct groups of neurons required for the formation and retrieval of an imprinted memory, defined neuromodulation that enables this critical period learning (tyramine and …

Processing Submillisecond Timing Differences in a Model Electrosensory System
<p>Perception of sensory cues requires peripheral encoding followed by extraction of behaviorally relevant signal components by central neurons. Some sensory systems can detect temporal information with submillisecond accuracy, despite these signals occurring faster than the approximately 1 ms …

Descending premotor target tracking systems in flying insects
The control of behaviour in all animals requires efficient transformation of sensory signals into the task-specific activation of muscles. Predation offers an advantageous model behaviour to study the computational organisation underlying sensorimotor control. Predators are optimised through …

Adaptive Economics: A neuroethological approach to the study of preferences, biases, and choice
A neuron's curse is that at every given time, with the information available to it, it must choose to either send a signal to its neighbouring cells or remain silent. It has evolved to be the optimal decision unit and, together with around 86 billion of its neighbours, the neuron keeps us alive, …

Reciprocal interactions between feeding and turning motor networks mediate foraging decisions in a predatory sea-slug
All animals constantly select among an array of competing behaviors in response to environmental stimuli and internal state to maximize their fitness. In simpler invertebrate nervous systems, decision-making arises at the level of antagonistic and cooperative interactions between motor networks …

Environmental influences on the development of the female honeybee brain Apis mellifera
Für die Honigbiene spielt der Geruchssinn eine entscheidende Rolle bei der Kommunikation innerhalb des Sozialstaates. Kastenspezifische, auf uweltbedingten Einflüssen basierende sowie altersbedingte Unterschiede im olfaktorisch gesteuerten Verhalten liefern ein hervorragendes Modellsystem für diese …
