In this episode I chat with Dr Barry O'Neill,  Senior Specialist in Neurocognition at the Nestle Brain Health Department.  Barry articulates exactly what neuroscience actually is and we discuss why it's used in research, how it is measured and what it can tell us about brain performance.  We chat through Barry's vast array of neuroscience application spanning clinical trials, to sports performance, to infant development and also why understanding your cognitive state can benefit your performance at work.  Caffeine, work patterns, sleep, exercise and wellbeing are all covered off in this fantastic insight into the world of neuroscience and cognition.
