Sensory function is mediated by interactions between external stimuli and intrinsic cortical
dynamics that are evident in the modulation of evoked responses by cortical state. A number …

To understand the strategies used by the brain to analyze complex environments, we must
first characterize how the features of sensory stimuli are encoded in the spiking of neuronal …

Recordings of single neurons have yielded great insights into the way acoustic stimuli are
represented in auditory cortex. However, any one neuron functions as part of a population …

The present study explores the issue of cortical coding by spike count and timing using
statistical and information theoretic methods. We have shown in previous studies that …

Spontaneous activity plays an important role in the function of neural circuits. Although many
similarities between spontaneous and sensory-evoked neocortical activity have been …

In the auditory system, early neural stations such as brain stem are characterized by strict
tonotopy, which is used to deconstruct sounds to their basic frequencies. But higher along …

How does auditory cortex represent auditory stimuli, and how do these representations
contribute to behavior? Recent experimental evidence suggests that activity in auditory …

An important question in sensory neuroscience is what coding strategies and mechanisms
are used by the brain to detect and discriminate among behaviorally relevant stimuli. There …

Neural representations of even temporally unstructured stimuli can show complex temporal
dynamics. In many systems, neuronal population codes show 'progressive differentiation' …

The activity of neural populations is determined not only by sensory inputs but also by
internally generated patterns. During quiet wakefulness, the brain produces spontaneous …
