Neural computations underlying cognition and behavior rely on the coordination of neural
activity across multiple brain areas. Understanding how brain areas interact to process …

The drift-diffusion model (DDM) is an important decision-making model in cognitive
neuroscience. However, innovations in model form have been limited by methodological …

The brain represents sensory variables in the coordinated activity of neural populations, in
which tuning curves of single neurons define the geometry of the population code. Whether …

Accumulating evidence to make decisions is a core cognitive function. Previous studies
have tended to estimate accumulation using either neural or behavioral data alone. Here we …

The gradual accumulation of noisy evidence for or against options is the main step in the
perceptual decision-making process. Using brain-wide electrophysiological recording in …

Decision-making based on noisy sensory stimuli is a fundamental part of everyday life. In
this thesis, we present three studies that seek to advance the understanding of the …

The question of how the collective activity of neural populations in the brain gives rise to
complex behaviour is fundamental to neuroscience. At the core of this question lie …
