Human prefrontal cortex: evolution, development, and pathology.
The prefrontal cortex is critical to many cognitive abilities that are considered particularly human, and forms a large part of a neural system crucial for normal socio-emotional and executive functioning in humans and other primates. In this chapter, we survey the literature regarding prefrontal development and pathology in humans as well as comparative studies of the region in humans and clos...
متن کاملPrenatal development of parvalbumin immunoreactivity in the human striate cortex.
In human primary visual cortex, parvalbumin (PV) is expressed by Cajal-Retzius cells in layer I by 20 weeks of gestation (20W), but its immunoreactivity is mostly lost by term. PV immunoreactivity in layers II-VI mainly develops later, from 26 to 34W, following an approximately 'inside-outside' sequence in a series of bands. PR-positive perikarya appear in layer V by 20W, but only in small numb...
متن کاملDevelopment of Relative Disparity Sensitivity in Human Visual Cortex.
Stereopsis is the primary cue underlying our ability to make fine depth judgments. In adults, depth discriminations are supported largely by relative rather than absolute binocular disparity, and depth is perceived primarily for horizontal rather than vertical disparities. Although human infants begin to exhibit disparity-specific responses between 3 and 5 months of age, it is not known how rel...
متن کاملDevelopment of local circuits in human visual cortex.
How we see the world largely depends on the organization of neuronal circuits in visual cortex. Physiological recordings in mammals indicate that circuits develop over a period that extends well into early postnatal ages (LeVay et al., 1980; Albus and Wolf, 1984). Our understanding of how these circuits are assembled during development is still fragmentary (Katz and Callaway, 1992). Here we des...
متن کاملHeterogeneous and nonlinear development of human posterior parietal cortex function
Human cognitive problem solving skills undergo complex experience-dependent changes from childhood to adulthood, yet most neurodevelopmental research has focused on linear changes with age. Here we challenge this limited view, and investigate spatially heterogeneous and nonlinear neurodevelopmental profiles between childhood, adolescence, and young adulthood, focusing on three cytoarchitectonic...
