Temporal dynamics of chromatic tuning in macaque primary visual cortex
Article Abstract:
Cortical neurons respond in different ways to stimuli where there are chromatic shifts, and the responsibity changes over time. The visual system is faced with a difficult computational challenge in trying to distinguish intensity variations from color. This is so due to the way that all light wavelengths are absorbed by each cone photoreceptor type. The primary visual cortex of the macaque combines outputs of the geniculate cell types.

Feature-based attention influences motion processing gain in macaque visual cortex
Article Abstract:
The influence of attention on sensory selectivity of neurons in visual cortex has been studied. Middle temporal visual area (MT) neurons have been linked to psychophysical performance in motion tasks. MT neurons of two macaque monkeys were recorded during displays of coherently moving random dot patterns (RDP). Attention was found to increase the gain of direction-selective neurons without narrowing the direction-tuning curves.

Orofacial somatomotor responses in the macaque monkey homologue of Broca's area
Article Abstract:
A distinct cortical area that is architectonically comparable to human area 44 is a monkey area 44 that is involved with the orofacial musculature. It is suggested that area 44 might have evolved originally as an area exercising high-level control over orofacial actions, including those related to communicative acts, and that, in the human brain, area 44 eventually also came to control certain aspects of the speech act.
