Attention and stochastic dynamics

Show Summary Details


Recent observations from a number of cognitive neuroscience experiments led to an alternative account of attention termed the ‘biased competition hypothesis’, which aims to explain the computational algorithms governing visual attention and their implementation in the brain's neural circuits and neural systems. This chapter shows how biased competition can operate as a dynamical process in a precise computational framework that enables multiple interacting brain systems with bottom-up and top-down effects to be analysed, and shows how noise can affect the stability of these attentional processes.

Keywords: cognitive neuroscience; biased competition hypothesis; visual attention; noise
