Neuroanatomical characteristics and speech perception in noise in older adults
Objectives: Previous research has attributed older adults' difficulty with perceiving speech in
noise to peripheral hearing loss. However, recent studies have suggested a more complex …

Multisensory decision-making in rats and humans
We report a novel multisensory decision task designed to encourage subjects to combine
information across both time and sensory modalities. We presented subjects, humans and rats, …

Posterior parietal cortex guides visual decisions in rats
Neurons in putative decision-making structures can reflect both sensory and decision
signals, making their causal role in decisions unclear. Here, we tested whether rat posterior …
