Probabilistic association learning



We are recruiting healthy adults between 18 and 45 years of age to take part in a study of the relationship among probabilistic association learning (a type of non-conscious learning), schizotypal personality traits (involving odd behaviours and/or beliefs in some people), striatal function (an area deep inside the brain shown to be important for this type of non-conscious learning) and genes important to striatal function.

All participants will be asked to complete (within two hours) three questionnaires, a computerized learning test, six brief “pencil and paper” cognitive tests and to provide a blood sample for genetic analysis. Some participants (based on their questionnaire scores) will be asked to come back to receive a functional magnetic resonance image scan of the brain.

Reimbursement of $20.00 per visit will be provided for your time and for out-of-pocket expenses.

If you have any questions or are interested in participating, please feel free to contact the research team.

See what’s going on at NeuRA


The cold case of schizophrenia - broken wide open!

‘It is like they were miraculously healed!’’ Schizophrenia is diagnosed by clinical observation of behaviour and speech. This is why NeuRA researchers are working hard to understand the biological basis of the illness. Through hours of work and in collaboration with doctors and scientists here and around the world, NeuRA has made an amazing breakthrough. For the first time, researchers have discovered the presence of antibodies in the brains of people who lived with schizophrenia. Having found these antibodies, it has led NeuRA researchers to ask two questions. What are they doing there? What should we do about the antibodies– help or remove them? This is a key breakthrough. Imagine if we are treating schizophrenia all wrong! It is early days, but can you imagine the treatment implications if we’ve identified a new biological basis for the disease? It could completely change the way schizophrenia is managed, creating new treatments that will protect the brain. More than this, could we be on the verge of discovering a ‘curable’ form of schizophrenia? How you can help We are so grateful for your loyal support of schizophrenia research in Australia, and today I ask if you will consider a gift today. Or, to provide greater confidence, consider becoming a Discovery Partner by making a monthly commitment. We believe there is great potential to explore these findings. Will you help move today’s breakthrough into tomorrow’s cure? To read more about this breakthrough, click ‘read the full story’ below.
