The dominance of imaginative and prescient is so powerful in sighted people who contact is typically regarded as a minor perceptual modality. even if, contact is a strong device which contributes considerably to our wisdom on area and gadgets. Its in depth use by means of blind humans permits them to succeed in an analogous degrees of information and cognition as their sighted friends. during this e-book, really expert researchers current the hot country of information in regards to the cognitive functioning of contact. After an research of the neurophysiology and neuropsychology of contact, exploratory handbook behaviours, intramodal haptic (tactual-kinesthetic) skills and cross-modal visual-tactual coordination are tested in babies, childrens and adults, and in non-human primates. those reports trouble either sighted and blind individuals with the intention to understand even if early visible deprivation modifies the modes of processing house and items. The final part is dedicated to the technical units favouring the college and social integration of the younger blind: Braille interpreting, use of raised maps and drawings, "sensory substitution" monitors, and new applied sciences of conversation tailored for the blind.

Описание: В 1966 году в Национальной библиотеке в Мадриде были обнаружены два манускрипта, написанные Леонардо. Когда-то они не были учтены при каталогизации, и об их существовании не было известно. Этим двум манускриптам дали условные названия «Мадридский кодекс I» и «Мадридский кодекс II».
«Мадридский кодекс I» состоит из 192 листов 1490—1499 годов написания, содержащих изображения различных механизмов и изложения теории механики. Хотя работа и посвящена механике, в ней есть заметки по астрономии и по оптике.
«Мадридский кодекс II» был создан Леонардо в 1503—1505 гг. и состоит из 158 листов. Он собрал исследования в области геометрии, такие, например, как «квадратуры круга». Кроме этого, в нём содержатся работы по перспективе и оптике. В книге можно найти эскизы морских и топографических карт, рассматриваются проблемы военной техники и архитектуры. Самое интересное в этом кодексе — неосуществлённый проект изменения русла реки Арно, эскизы фрески «Битва при Ангиари» и конного памятника Франческо Сфорца.

Example text

We have long known that cortical organization is characterized by great plasticity (for a review, cf. Buonomano & Merzenich 1998). Hebb (1949) had already proposed a form of plasticity in synaptic connections: “Neurons which discharge together will link together”. In addition, if the transmission of sensory information between one part of the body and its   Edouard Gentaz and Maryse Badan cortical representation is interrupted, the corresponding cortical zone does not remain inert, but reorganizes, letting itself be invaded by the adjacent cortical zone.

Dehaene 1997; Posner & Raichle 1998). We know that the neural mechanisms underlying cognitive and sensory-motor activities give rise to a continuous and considerable metabolic requirement. This demand for energy is principally met by the use of glucose. As the brain has very limited reserves, it is dependent on a continuous supply of oxygen and glucose, and the regional variations correspond fairly exactly to the actual metabolic needs. So, by measuring regional blood deficits or the cerebral consumption of oxygen and glucose, one can estimate the metabolic activity linked to the synaptic activity underlying cognitive and sensory-motor tasks.
