Fear memories allow animals to predict and avoid possibly dangerous situations. However, if an expected threat does not happen, it is also important to learn to be less fearful. This re-learning process is called memory extinction. Although extinction has been postulated for many years to involve parallel memories, it is unclear how and where extinction memories are formed and how they compete with the original memory to neutralise learned fear....

The shape and function of every cell in our body is determined by the amount and types of protein molecules that they produce. The building plan for each cell is stored in the DNA of the genome. This information is carefully copied and passed on to daughter cells during the reproduction, development and growth of all living organisms. Any changes (mutations) that occur in the DNA of each cell could potentially have devastating effects on the...

The bus doesn’t always arrive on time and your favourite dish is not always on the menu at the local restaurant. To account for an ever-changing world, animals must possess neural mechanisms to constantly update their learned predictions so that their choices correctly incorporate the new, sometimes contradicting information. A recent study from the Waddell lab in Nature reveals how the strength of memory-directed behavior is...

Hunger promotes the behavioural expression of food-seeking memories. A recent study from the Waddell lab in Neuron discovered the neural circuit mechanism that provides this control. Hunger-state modulation increases the activity of a pair of inhibitory interneurons of the mushroom body so that odours more strongly drive mushroom body output pathways that favour approach behaviour. Surprisingly aversive learning promotes odour avoidance...

Memories are stored in the fan-out fan-in neural architectures of the mammalian cerebellum and hippocampus and the insect mushroom bodies. However, whereas key plasticity occurs at glutamatergic synapses in mammals, the neurochemistry of the memory-storing mushroom body Kenyon cell output synapses has been debated for decades. A recent study from the Waddell lab in Neuron shows acetylcholine is a Kenyon cell neurotransmitter in...

Finding locations in the brain where memories are formed, and understanding how memories are retrieved to instruct behaviour, are major goals of neuroscience. A recent study from the Waddell lab in Neuron localised memories to specific pathways in the output network of the fruit fly mushroom bodies. Surprisingly, reward and punishment learning altered odour-driven-activity of this connection in opposite directions. Moreover, it was...

Scott Waddell has received the Liliane Bettencourt Prize for Life Sciences 2014. Each year, the Bettencourt Schueller Foundation awards the Prize to a young researcher (under 45), recognized in the scientific community for the quality of his or her international publications. In addition to the recipient’s scientific recognition, the award-winning researcher must conduct a research project that is particularly promising and be able to...

Drinking water is innately rewarding to thirsty animals. A recent study from the Waddell lab in Nature Neuroscience demonstrated that neural circuit mechanisms of water wanting, learning and liking can be distinguished by their requirements for dopaminergic neurons in the brain of thirsty flies. The full paper can be viewed Lin et al. (2014). Suewei Lin...

CNCB team shows that the neural reward system of flies is more similar to that of mammals than previously thought. A team led by Scott Waddell of the Centre for Neural Circuits and Behaviour shows that the fruit fly brain contains an evaluation system that is more similar to mammals than previously recognised. The research, published in Nature this month, demonstrates that the neurotransmitter dopamine, which is synonymous...
