Circuits and mechanisms for surround modulation in visual cortex
Surround modulation (SM) is a fundamental property of sensory neurons in many species and
sensory modalities. SM is the ability of stimuli in the surround of a neuron's receptive field (…

[HTML][HTML] Top-down feedback controls spatial summation and response amplitude in primate visual cortex
Sensory information travels along feedforward connections through a hierarchy of cortical
areas, which, in turn, send feedback connections to lower-order areas. Feedback has been …

[PDF][PDF] An open resource for non-human primate optogenetics
Optogenetics has revolutionized neuroscience in small laboratory animals, but its effect on
animal models more closely related to humans, such as non-human primates (NHPs), has …

[HTML][HTML] A direct interareal feedback-to-feedforward circuit in primate visual cortex
The mammalian sensory neocortex consists of hierarchically organized areas reciprocally
connected via feedforward (FF) and feedback (FB) circuits. Several theories of hierarchical …

Four projection streams from primate V1 to the cytochrome oxidase stripes of V2
F Federer, JM Ichida, J Jeffs, I Schiessl… - Journal of …, 2009 - Soc Neuroscience
In the primate visual system, areas V1 and V2 distribute information they receive from the
retina to all higher cortical areas, sorting this information into dorsal and ventral streams. …

The influence of complex action knowledge on representations of novel graspable objects: evidence from functional magnetic resonance imaging
The influence of action knowledge associated with novel objects was investigated using
functional magnetic resonance imaging. Participants were trained on complex actions …

Two projection streams from macaque V1 to the pale cytochrome oxidase stripes of V2
In the primate visual cortex, areas V1 and V2 distribute information they receive from the retina
to virtually all extrastriate cortex, parsing this information into dorsal and ventral streams. …
