Action

…together with subtle perception and action in competitive games, provide concrete settings for examining those perspectives.

Rajesh Rao revisits predictive coding and its extension from sensory inference to action, including proposed roles for cortical layers. He also describes brain-to-brain interfaces and neural co-processors that use artificial networks to restore or augment function, before discussing his separate work on the undeciphered Indus script.

Working memory is about the past but for the future. Adopting such a future-focused perspective shifts the narrative of working memory as a limited-capacity storage system to working memory as an anticipatory buffer that helps us prepare for potential and sequential upcoming behaviour. In my talk, I will present a series of our recent studies that have started to reveal emerging principles of a working memory that looks forward – highlighting, amongst others, how selective attention plays a vital role in prioritising internal contents for behaviour, and the bi-directional links between visual

…and of the consequences of its actions in that environment. While such representations—e.g. of head direction and value—have been extensively studied, how they are combined to guide behavior is not well understood. I will discuss how we are exploring these questions using a classical visual learning paradigm for the fly. I’ll begin by describing a simple policy that, when tethered to an internal representation of heading, captures structured behavioral variability in t

Neuroscientists believe that perception, action and cognition arise from brain’s activity. A major challenge in neuroscience is to understand how brain’s complex circuits give rise to activity patterns that support these different functions. I will discuss different ways of mapping neural circuits in the brain, and how we can relate the structure of neural circuits to the computations that take place within them, with an emphasis on the visual system.
