Characterisation of monoaminergic transmission in Central Amygdala. 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 invest ....Characterisation of monoaminergic transmission in Central Amygdala. 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
The human mirror system and the perception of others' actions. This research will provide greater understanding of how the human mirror system operates for the perception of actions, a crucial first-step toward understanding disorders of action perception such as autism and apraxia. The research program will also contribute greatly to building national capacity in cognitive neuroscience research, using advanced brain imaging methods. The fellow actively encourages and mentors young scientists, o ....The human mirror system and the perception of others' actions. This research will provide greater understanding of how the human mirror system operates for the perception of actions, a crucial first-step toward understanding disorders of action perception such as autism and apraxia. The research program will also contribute greatly to building national capacity in cognitive neuroscience research, using advanced brain imaging methods. The fellow actively encourages and mentors young scientists, organises advanced workshops that bring brain imaging researchers around the world to Australia, and builds international collaborations based around high-field brain imaging. The Future Fellowship will substantially enhance these activities, building capacity and enhancing Australia's reputation in cognitive neurosciences.Read moreRead less
Presynaptic mechanisms of general anaesthesia in the fly brain. General anaesthesia is a routine procedure for both human and veterinary surgery and for any experimental paradigms requiring immobilization of animals. By abolishing consciousness, these drugs provide practitioners with an ideal way of manipulating subjects under conditions when responsiveness might be undesirable. Understanding how manipulating synaptic release mechanisms might modulate anaesthetic potency will be valuable for eve ....Presynaptic mechanisms of general anaesthesia in the fly brain. General anaesthesia is a routine procedure for both human and veterinary surgery and for any experimental paradigms requiring immobilization of animals. By abolishing consciousness, these drugs provide practitioners with an ideal way of manipulating subjects under conditions when responsiveness might be undesirable. Understanding how manipulating synaptic release mechanisms might modulate anaesthetic potency will be valuable for eventually being able to better control the anaesthetized state in human and animal subjects. By understanding general anaesthesia across multiple levels of brain function, we will at the same time be answering fundamental questions pertaining to mechanisms of perception and awareness.

Processing of social communication calls in primate auditory cortex. This research will advance our understanding of the brain mechanisms involved in perception of sound. This will help to understand disorders of speech and hearing following brain damage and may assist in efforts to develop better hearing aids, as well as other speech recognition technologies. In addition, we will develop a primate for studying processing of sound in the brain that will be useful in future research to develop ....Processing of social communication calls in primate auditory cortex.
