To flee or not to flee: surviving on incomplete information. Even lowly animals, like the Australian fiddler crabs we will be investigating, are surprisingly competent in making the right decisions in complex situations. They actively acquire information and make good use of it to assure their immediate safety and their long term gains. Animals are exquisitely honed by evolution and we would benefit greatly by understanding what makes them so competent: on a theoretical level, we may learn about ....To flee or not to flee: surviving on incomplete information. Even lowly animals, like the Australian fiddler crabs we will be investigating, are surprisingly competent in making the right decisions in complex situations. They actively acquire information and make good use of it to assure their immediate safety and their long term gains. Animals are exquisitely honed by evolution and we would benefit greatly by understanding what makes them so competent: on a theoretical level, we may learn about efficient rules of good decision making and on a practical level, we may be able to design more flexible, robust and clever machines. Besides being useful in this wider context, the results of our research will thus also contribute to a new and 'sophisticated' appreciation of the cognitive design of animal.Read moreRead less

This project will identify the distribution and function of dopamine, serotonin and noradrenalin receptors on the various cell types and their inputs, in the medial, lateral and capsular divisions of Central Amygdala (CeA). We will test for tonic endogenous activation of monoaminergic receptors and synaptic release from electrically stimulated fibers terminating in CeA. Using paired recordings and calcium imaging, we will investigate intracellular mechanisms underlying monoamine receptor mediated effects. These findings when correlated with published behavioural studies will provide greater understanding of the role of the divisions of CeA and the inputs they receive, in the function of the amygdala.Read moreRead less

Being able to see is a crucial aspect of our daily lives, which happens so effortlessly that it tends to be taken for granted. In comparison with other animals and artificial systems, the primate visual cortex is unsurpassed in its capacity to interpret complex and dynamic environments, in a manner that is fast and computationally robust. Discovering how this happens in terms of interactions between cells in the brain can help us design more efficient artificial systems capable of vision. This in turn can have profound implications for the creation of new technologies such as artificial eyes, autonomous robots, and intelligent sensors, and may also result in future benefits for medical science.Read moreRead less
