Journal ArticleDOI
Parallel Evolution of Cortical Areas Involved in Skilled Hand Use
Jeffrey Padberg,João G. Franca,Dylan F. Cooke,Juliana G. M. Soares,Marcello G. P. Rosa,Mario Fiorani,Ricardo Gattass,Leah Krubitzer +7 more
TL;DR: The similarity of these fields in cebus monkeys and distantly related macaque monkeys with similar manual abilities indicates that the range of cortical organizations that can emerge in primates is constrained, and those that emerge are the result of highly conserved developmental mechanisms that shape the boundaries and topographic organizations of cortical areas.
Journal ArticleDOI
Visual response properties of pretectal units in the nucleus of the optic tract of the opossum
Eliane Volchan,C. E. Rocha-Miranda,Cristovam W. Picanço-Diniz,B. Zinsmeisser,R. F. Bernardes,João G. Franca +5 more
TL;DR: Single-units recorded from the nucleus of the optic tract showed excitation in response to random check patterns presented on a tangent screen to the contralateral eye, moving in a temporal to nasal direction and/or inhibition in the opposite direction.
Journal ArticleDOI
The organization of somatosensory cortex in the short-tailed opossum ( Monodelphis domestica )
TL;DR: The organization of neocortex in the short-tailed opossum was explored with multiunit microelectrode recordings from middle layers of cortex, revealing the presence of at least two systematic representations of the contralateral body surface located in a continuous strip of cortex running from the rhinal sulcus to the medial wall.
Journal ArticleDOI
A morphometric study of the progressive changes on NADPH diaphorase activity in the developing rat's barrel field.
Marco Aurelio M. Freire,Walace Gomes-Leal,Walther Augusto de Carvalho,Joanilson S. Guimarães,João G. Franca,Cristovam W. Picanço-Diniz,Antonio Pereira +6 more
TL;DR: Both high neuropil reactivity and differential distribution of NADPH-d neurons during SI development suggest a role for nitric oxide throughout barrel field maturation.
Journal ArticleDOI
Morphometric variability of nicotinamide adenine dinucleotide phosphate diaphorase neurons in the primary sensory areas of the rat.
Marco Aurelio M. Freire,Jean Faber,Cristovam W. Picanço-Diniz,João G. Franca,Antonio Pereira +4 more
TL;DR: The results suggest that the nitrergic cortical circuitry of primary sensory areas of the rat is differentially specialized, probably reflecting peculiarities of both habit and behavior of the species.
