Spontaneous and driven cortical activity: implications for computation
DL Ringach - Current opinion in neurobiology, 2009 - Elsevier
The traditional view of spontaneous neural activity as 'noise'has been challenged by recent
findings suggesting that:(a) spontaneous activity in cortical populations is highly structured …

Linearity and normalization in simple cells of the macaque primary visual cortex
Simple cells in the primary visual cortex often appear to compute a weighted sum of the light
intensity distribution of the visual stimuli that fall on their receptive fields. A linear model of …

Orientation selectivity in macaque V1: diversity and laminar dependence
DL Ringach, RM Shapley, MJ Hawken - Journal of neuroscience, 2002 - Soc Neuroscience
We studied the steady-state orientation selectivity of single neurons in macaque primary
visual cortex (V1). To analyze the data, two measures of orientation tuning selectivity …
