Orientation columns exist in the primary visual cortex (V1) of cat and primates but not mouse.
Intriguingly, some recent studies reported the presence of orientation and direction columns …

Whether general principles can explain the layouts of cortical maps remains unresolved. In
primary visual cortex of ferret, the relationships between the maps of visual space and …

In early visual cortex different stimulus parameters are represented in overlaid feature maps.
Such functioning was extensively explored by the use of drifting gratings characterized by …

Within the visual cortex of several mammalian species, more circuitry is devoted to the
representation of vertical and horizontal orientations than oblique orientations. The …

In the earliest cortical stages of visual processing, a scene is represented in different
functional domains selective for specific features. Maps of orientation and spatial frequency …

Visual scenes can be readily decomposed into a variety of oriented components, the
processing of which is vital for object segregation and recognition. In primate V1 and V2 …

In this chapter, which was the North American plenary address at the 2009 Bion in Boston
conference, Grotstein masterfully compares and contrasts Bion's theory of dreaming with that …

Wide-field voltage imaging is unique in its capability to capture snapshots of activity—across
the full gradient of average changes in membrane potentials from subthreshold to …

A fundamental question in neuroscience is how sensory information is represented in the
brain. In particular, what principles guide the spatial organization of neurons with regard to …

46 Fifty years ago, neurons in primary visual cortex were discovered 47 to have local
receptive fields that are selective for stimulus orientation 48 (Hubel and Wiesel, 1959) …
