Searching for the genetic components of long-term memory for operant self-learning in Drosophila
In contrast to many other forms of learning, the genetic components of operant self-learning, a kind of motor-learning, are still poorly understood. So far, only Protein Kinase C (PKC) and FoxP have been identified as necessary for operant self-learning. It […] ↓ Read the rest of this entry…
Open knowledge maps visualizes the results of a literature search, organizing publications according to content into different fields.
In every behavioral population paradigm where groups of animals are being exposed to forced-choice situations, there is the question whether or not the individual animals can be assumed to make their own choices. We approach this hypothesis by testing Drosophila […] ↓ Read the rest of this entry…
In 1918, McEwen demonstrated that wing defects, caused by mutation or damage, profoundly affect phototaxis in walking Drosophila fruit flies (McEwen, 1918). We have recently described experiments showing that flies are constantly monitoring their flying capability and adjust their light/dark […] ↓ Read the rest of this entry…
Variability is an adaptive and ubiquitous feature of all our behaviors, which is actively regulated according to task demands. Behavioral variability explains why under identical circumstances, individuals are able to initiate different actions. The amount of behavioral variability predicts operant […] ↓ Read the rest of this entry…
Animals exhibit innate preferences for different stimulus modalities and intensities, which likely reflect evolutionary responses to specific ecological needs. Insects such as Drosophila move towards a light source when startled. Given the robustness of this response, positive phototaxis has been […] ↓ Read the rest of this entry…

Even in the absence of external stimuli, brains are capable of initiating spontaneous actions. Spontaneous turning attempts (yaw torque) initiated by Drosophila fruit flies tethered at the torque meter, are not completely governed by random noise in the brain but […] ↓ Read the rest of this entry…

World-learning (the process assigning value to sensory stimuli) and self-learning (the process assigning value to a specific action or movement) are two biological components of operant learning. The fundamental value of the distinction between self- and world-learning is reflected in […] ↓ Read the rest of this entry…

During operant learning, animals learn to associate external cues (world-learning) and/or their self-generated motor program (self-learning) with the reward or punishment. Previous work dissociated these two types of learning using different paradigms in the fly torque meter apparatus (“flight simulator”),. […] ↓ Read the rest of this entry…
