Unlike in Hubel and Wiesel's animals, whose visual deficits were locked in once adulthood arrived, the visual systems of mice with abnormal or missing perineuronal nets retained the ability to be sculpted, Fawcett and colleagues have found.

La tendencia no significativa a la acidez a nivel del yeyuno en comparacion con el ileon (Cuadro 2) fue confirmada por Hubel (1969), quien demostro que los dipeptidos y aminoacidos neutros se absorben mejor a nivel de yeyuno, ya que necesitan una mayor acidez para su absorcion por usar un cotransportador que permite el ingreso de dipeptidos ante la mayor presencia de H+ (Ganapathy y Leibach, 1983; Ganapathy et al.
Shown first in the newborn cat, specificity of input to ocular columns is achieved by an activity-dependent elimination of many of the original terminal connections from one or the other eye (Wiesel and Hubel, 1965).
These inequalities are propagated further along the visual system, with relatively larger regions of lateral geniculate nucleus (LGN) and visual cortex being devoted to foveal vision than to peripheral vision which is named cortical magnification or scaling factor (Connolly & Van Essen, 1984; Daniel & Whitteridge, 1961; Hubel & Wiesel, 1974; for a review see Battista, Kalloniatis, & Metha, 2005).
The study of our perceptual processes as linked to cognition has continued in many directions, from psychology to biology to social factors (Caelli, 1981; Bruce, Green, and Georgeson, 1996; Schwartz, 2004; Hubel and Wiesel, 2005).
The book has been very well received in the scientific and neurobiological circles and as an example here is a comment from the Nobel Prize winner David Hubel on the cover: "It had been widely thought that an adult, crass-eyed since infancy, could never acquire stereovision, but to everyone's surprise Barry succeeded.
The articles are thoughtfully selected and presented to reflect the development of the field as well as its controversies, with many articles included that report on early research that was widely influential and both drew attention to a field of study and prepared the foundation for that field, among them, the work of Hubel and Wiesel on perception, Posner and Keele on object recognition, and P.
Muitas pesquisas, desde os estudos pioneiros de Hubel e Wiesel na decada de 60 (1962, 1965, 1968), relatam que a privagao sensorial parcial ou total de um sistema sensitivo pode alterar a resposta do sistema privado de estimulagao e/ou de outros sistemas sensoriais.
