Neuroanatomy: Mushrooming mushroom bodies
A revolution is spreading in the study of mushroom bodies, structures within the insect brain that mediate learning and memory processes and pheromonal discrimination of the opposite sex.
متن کاملMushroom-bodies mediate hierarchical interactions
Different brain circuits mediate the acquisition of skills and habits (via operant/instrumental learning) and the acquisition of facts (via classical/Pavlovian learning). Realistic learning situations always comprise interactions of skill-and fact-learning components (composite learning). So far, these interactions have escaped thorough scrutiny. Fixed flying Drosophila melanogaster at the torq...
متن کاملHydroxyurea ablation of mushroom bodies in Drosophila.
Chemical ablation is an effective tool for studying nervous system development and function in Drosophila. Hydroxyurea (HU) inhibits ribonucleotide reductase, blocking DNA synthesis, and killing dividing cells. The specificity of HU ablation is thus dependent on developmental events. In this respect, HU is useful in determining temporal patterns of neuroblast proliferation and the origins of ne...
متن کاملMushroom Bodies Regulate Habit Formation in Drosophila
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 (i.e., classically). Interestingly, in many species, including humans, these learning processes occasionally lead to irrational decis...
متن کاملEvolution, discovery, and interpretations of arthropod mushroom bodies.
Mushroom bodies are prominent neuropils found in annelids and in all arthropod groups except crustaceans. First explicitly identified in 1850, the mushroom bodies differ in size and complexity between taxa, as well as between different castes of a single species of social insect. These differences led some early biologists to suggest that the mushroom bodies endow an arthropod with intelligence...
