Learning about relationships between stimuli (i.e., classical conditioning) and learning about consequences of one’s own behavior (i.e., operant conditioning) constitute the major part of our predictive understanding of the world. Since these forms of learning were recognized as two separate […] ↓ Read the rest of this entry…
To make good decisions, we evaluate past choices to guide later decisions. In most situations, we have the opportunity to simultaneously learn about both the consequences of our choice (i.e., operantly) and the stimuli associated with correct or incorrect choices […] ↓ Read the rest of this entry…
Brains are usually described as input/output systems: they transform sensory input into motor output. However, the motor output of brains (behavior) is notoriously variable, even under identical sensory conditions. The question of whether this behavioral variability merely reflects residual deviations […] ↓ Read the rest of this entry…
We have used a genetically tractable model system, the fruit fly Drosophila melanogaster to study the interdependence between sensory processing and associative processing on learning performance. We investigated the influence of variations in the physical and predictive properties of color […] ↓ Read the rest of this entry…
For experiments at the torque meter, flies are kept on standard fly medium at 25 degrees C and 60% humidity with a 12hr light/12hr dark regime. A standardized breeding regime assures proper larval density and age-matched cohorts. Cold-anesthetized flies are […] ↓ Read the rest of this entry…
In a permanently changing environment, it is by no means an easy task to distinguish potentially important events from negligible ones. Yet, to survive, every animal has to continuously face that challenge. How does the brain accomplish this feat? Building […] ↓ Read the rest of this entry…
Short-term memory in Drosophila melanogaster operant visual learning in the flight simulator is explored using patterns and colours as a compound stimulus. Presented together during training, the two stimuli accrue the same associative strength whether or not a prior training […] ↓ Read the rest of this entry…
Insects have been among the most widely used model systems for studying the control of locomotion by nervous systems. In Drosophila, we implemented a simple test for locomotion: in Buridan’s paradigm, flies walk back and forth between two inaccessible visual […] ↓ Read the rest of this entry…
The primary function of a brain is to produce adaptive behavioral choices by selecting the right action at the right time. In humans, attention determines action selection as well as memory formation, whereas memories also guide which external stimuli should […] ↓ Read the rest of this entry…
Baier A.; Wittek B. and Brembs B. (2002): Drosophila as a new model organism for the neurobiology of aggression? J. Exp. Biol. 205 (9): 1233-1240.
