A key issue in understanding the neural code for an ensemble of neurons is the nature and
strength of correlations between neurons and how these correlations are related to the …

Decoding the activity of a population of neurons is a fundamental problem in neuroscience.
A key aspect of this problem is determining whether correlations in the activity, ie, noise …

Neurons in the brain represent information in their collective activity. The fidelity of this
neural population code depends on whether and how variability in the response of one …

Highlights•Correlations re-distribute the noise in the neural population-
response.•Information is limited when signal and correlated noise overlap.•Heterogeneity …

In many cortical and subcortical areas, neurons are known to modulate their average firing
rate in response to certain external stimulus features. It is widely believed that information …

Response variability is often correlated across populations of neurons, and these noise
correlations may play a role in information coding. In previous studies, this possibility has …

How the brain encodes information in population activity, and how it combines and
manipulates that activity as it carries out computations, are questions that lie at the heart of …

The manner in which groups of neurons represent events in the external world is a central
question in neuroscience. Estimation of the information encoded by small groups of neurons …

Understanding how populations of neurons encode information is the challenge faced by
researchers in the field of neural coding. Focusing on the many mysteries and marvels of the …

We have used a combination of theory and experiment to assess how information is
represented in a realistic cortical population response, examining how motion direction and …
