Representational untangling by the firing rate nonlinearity in V1 simple cells
Recall of facial expressions and simple orientations reveals competition for resources at multiple levels of the visual hierarchy.
Many studies of visual working memory have tested humans' ability to reproduce primary visual features of simple objects, such as the orientation of a grating or the hue of a color patch, following a delay. A consistent finding...

Learning and experience are critical for translating ambiguous sensory information from our environments to perceptual decisions. Yet evidence on how training molds the adult human brain remains controversial, as fMRI at...

Efficient Coding in Visual Working Memory Accounts for Stimulus-Specific Variations in Recall.
Recall of visual features from working memory varies in both bias and precision depending on stimulus parameters. Whereas a number of models can approximate the average distribution of recall error across target stimuli...

Phonotactic steering and representation of directional information in the ascending auditory pathway of a cricket.
Directional hearing is crucial for animals depending on acoustic signals to locate a mate. We focused on crickets to explore the reliability of directional information forwarded to the brain by the ascending auditory interneuron...
