Different cortical dynamics in face and body perception: an MEG study. [PDF]
Evidence from functional neuroimaging indicates that visual perception of human faces and bodies is carried out by distributed networks of face and body-sensitive areas in the occipito-temporal cortex.

The Derivation of Direction Selectivity in the Striate Cortex [PDF]
In the central visual pathway of binocular animals, the property of directional selectivity (DS) is first exhibited in striate cortex. In this study, we sought to determine the neural circuitry underlying the transformation from non-DS neurons to DS cortical cells.

A simpler primate brain: the visual system of the marmoset monkey
Humans are diurnal primates with high visual acuity at the centre of gaze. Although primates share many similarities in the organisation of their visual centres with other mammals, and even other species of vertebrates, their visual pathways also show ...

Pyramidal cells are characterised by markedly different sized dendritic trees, branching patterns and spine density across the cortical mantle. Moreover, pyramidal cells have been shown to differ in structure among homologous cortical areas in different ...

Does Corticothalamic Feedback Control Cortical Velocity Tuning? [PDF]
The thalamus is the major gate to the cortex and its contribution to cortical receptive field properties is well established. Cortical feedback to the thalamus is, in turn, the anatomically dominant input to relay cells, yet its influence on thalamic ...

Orientation Selectivity and the Arrangement of Horizontal Connections in Tree Shrew Striate Cortex
Horizontal connections, formed primarily by the axon collaterals of pyramidal neurons in layer 2/3 of visual cortex, extend for millimeters parallel to the cortical surface and form patchy terminations.

The functional organization of area V2, I: Specialization across stripes and layers [PDF]
We used qualitative tests to assess the sensitivity of 1043 V2 neurons (predominantly multiunits) in anesthetised macaque monkeys to direction, length. orientation. and color of moving bar stimuli.

Cortical blood flow can be modulated by local activity across a range of species; from barrel-specific blood flow in the rodent somatosensory cortex to the human cortex, where BOLD-fMRI reveals numerous functional borders.

In principle, the development of sensory receptive fields in cortex could arise from experience-independent mechanisms that have been acquired through evolution, or through an online analysis of the sensory experience of the individual animal.
