I am interested in the wiring of the brain, how neurons grow and form neural circuits and their functions. My research focuses on neural circuitry underlying complex behaviors such as learning, memory, reward related behavior and movement. Disturbances in the neural circuitry of these behaviours contribute to pathophysiology of several neurological disorders such as drug addiction, depression, Parkinson’s disease, Huntington’s disease and Multiple sclerosis. I apply unique and interdisciplinary research tools of molecular biology, optogenetics, chemogenetics and behavioral neuroscience.

My Research Activities
Gibson, G.D., Prasad, A.A., Jean-Richard-dit-Bressel, P., Yau, J.O., Millan, E.Z., Liu, S., Campbell, E.J., Marchant, N.J., Power, J.M., Lawrence, A.J., & McNally, G.P. Segregated accumbens shell output pathways promote versus prevent relapse to alcohol seeking, accepted, Neuron IF: 13.97
Significance: shows anatomical and functional segregation of AcbSh output pathways to ventral tegmental area pathway promotes relapse whereas whereas the lateral hypothalamus pathway prevents in relapse.
- Prasad, A.A., & McNally GP. Ventral pallidum output pathways in context-induced reinstatement of alcohol seeking. The Journal of Neuroscience, 2016 Nov 16;36(46):11716-11726. IF: 6.747
Significance: This paper showed that VP output pathways to the subthalamic nucleus and also to the ventral tegmental area are necessary for reinstatement of alcohol seeking.
- Khoo, S. Y., Gibson, G. D., Prasad, A. A., & McNally, G. P. (2016). How contexts promote and prevent relapse to drug seeking. Genes Brain Behavior doi:10.1111/gbb. 12328
Significance: Comprehensive review of the behavioural and brain mechanisms enabling contexts to promote and prevent relapse to drug seeking.
- Morello, F., Prasad, A.A., Vieira de Sa, R., Anton-Bolanus, N., Leyva-Diaz, E., Renberg, K., Adolfs, Y., Tissir, F., Lopez-Bendito, G., & Pasterkamp J (2015). Frizzled3 controls axonal polarity and intermediate target entry during striatal pathway development. The Journal of Neuroscience, 35, 14205-14219. IF: 6.747, Cover of The Journal of Neuroscience
Significance: Established the embryonic ontogeny of the two main striatal pathways and identified novel roles for the axon guidance receptor Frizzled3 in uncharacterized aspects of striatal pathway formation
- Khoo, A.T., Gibson, G.S., Prasad, A.A., & McNally, G.P. (2015). Role of the striatopallidal pathway in renewal and reacquisition of alcohol-seeking. Behavioral Neuroscience, 129, 2 - 7. IF: 2.728,
Significance: The first paper using optogenetics in freely moving animals published from Australia. It showed that the striatopallidal pathway, previously thought to be obligatory for all forms of relapse, does not mediate context-induced reinstatement. Instead, a different pallidal input must be important for this relapse.
- Prasad, A.A., & McNally GP. Effects of vivo morpholino knockdown of lateral hypothalamus orexin/hypocretin on renewal of alcohol seeking. PLoS One. 2014 9, e110385 IF: 3.534
Significance: Shows relevance of proteins other than orexin within the lateral hypothalamus that may contribute to drug seeking behaviour.

Significance: Shows multiple role of Wnt5a on the development of dopaminergic neurons.

The Journal of Neuroscience. 29, 12542-57. IF: 6.747
Significance: Describes the crucial role for Semaphorin 3F in development of dopaminergic circuitry.

My Research Supervision
Areas of supervision
Parkinson’s disease (PD) is a neurodegenerative disorder. Approximately 32 Australians are being diagnosed daily. Deep brain stimulation (DBS) is a current treatment for Parkinson's disease (PD). Yet little is known about the non-motor effects of DBS on behaviours, such as motivation, learning and memory. This project applies optogenetic technology in the rodent PD model to better understand the motor and non-motor symptoms of PD. Optogenetics technology allows neural manipulation with millisecond control in freely moving animals. Overall this project studies brain and behaviour with cutting edge technologies develop in strategies to alleviate disabling motor and non-motor symptoms of PD.
Students will be trained to use Optogenetics, chemogenetics, animal behaviour, human tissue analysis and imaging techniques.

Injecting drug use is a behaviour strongly associated with other highly marginalised characteristics such as imprisonment, blood borne virus infections, homelessness and mental illness. This Centre for Research Excellence is focussed on injecting drug use and draws together a number of innovative studies about injecting drug use, plus provides seed funds for new projects. The Centre provides a mechanism for research translation to key stakeholders including consumers, policy makers and practitioners.
