Over the past decade fMRI researchers have developed increasingly sensitive techniques
for analyzing the information represented in BOLD activity. The most popular of these …

Response reliability is complementary to more conventional measurements of response
amplitudes, and can reveal phenomena that response amplitudes do not. Here we review …

A neuronal population encodes information most efficiently when its stimulus responses are
high-dimensional and uncorrelated, and most robustly when they are lower-dimensional …

Understanding how brains process sensory signals in natural environments is one of the key
goals of twenty-first century neuroscience. While brain imaging and invasive …

Humans can see and name thousands of distinct object and action categories, so it is
unlikely that each category is represented in a distinct brain area. A more efficient scheme …

Speech comprehension requires that the brain extract semantic meaning from the spectral
features represented at the cochlea. To investigate this process, we performed an fMRI …

A fundamental challenge for systems neuroscience is to quantitatively relate its three major
branches of research: brain-activity measurement, behavioral measurement, and …

How the human auditory system extracts perceptually relevant acoustic features of speech is
unknown. To address this question, we used intracranial recordings from nonprimary …

Little is known about how attention changes the cortical representation of sensory
information in humans. On the basis of neurophysiological evidence, we hypothesized that …

Recent studies have used fMRI signals from early visual areas to reconstruct simple
geometric patterns. Here, we demonstrate a new Bayesian decoder that uses fMRI signals …
