Animals owe much of their fitness to their behavior. They often have a large behavioral repertoire that they have to manage. For this, they need their brain. Using Drosophila as the study case, this chapter depicts animals as autonomous agents and the brain as a behavioral organizer. Behavior is active. It is generated for its consequences. It serves to change or restore the animal’s condition, with no guarantee for improvement. There are two kinds of activity—reactivity and initiating activity. If in a special situation, the animal’s repertoire contains a behavior with sufficiently positive inferred outcome and this is activated, it is called a reaction. Most situations, however, provide no special cues for which reactions would be available. Animals do not have to wait. They can activate behaviors ‘by themselves,’ in search of one with positive outcome.
In 1984, Hawkins and Kandel published a seminal paper titled “Is There a Cell-Biological Alphabet for Simple Forms of Learning?” Based on their early findings of the cooperative regulation of adenylyl cyclase in sensory neurons of ...
This is difficult to address in the mammalian brain due to its enormous complexity, and invertebrates offer major advantages for learning and memory studies because of their relative simplicity.
The pioneering work of J. Z. Young, M. J. Wells, and colleagues confirmed that a specific structure in the brain of the modern cephalopods, the vertical lobe, is involved in their highly sophisticated behaviors.
Invertebrate Learning and Memory
The behavior of insects transcends elementary forms of adaptive responding to environmental changes.
Mathematical models and computer simulations play important roles in developing a better understanding of learning and memory mechanisms.
In this review, we (1) explore the evolution of individual recognition in paper wasps, including the selective pressures thought to shape the origin and maintenance of individual recognition; (2) discuss the extent of memory for specific ...
in the establishment of prey preference in juvenile cuttlefish may depend on different rules than those in avoidance learning.85 In the chick, it has been shown that memories supporting imprinting preferences and those consecutive to ...
A robot that senses and interacts autonomously with the real world can be used to embody specific hypotheses about the mechanisms of learning in invertebrates.
We consider issues of social learning in insect societies.
