“…When babies were awake, the right prefrontal cortex was additionally activated. These areas are similar to those activated in adults, and interestingly the prefrontal cortex is activated in adult subjects who are retrieving verbal information from memory (Shallice et al, 1994).…”

Recent advances in cognitive neuroscience have allowed us to begin investigating the development of both structure and function in the infant brain. However, despite the rapid evolution of technology, surprisingly few studies have examined the intersection between brain and behaviour over the first years of life. Even fewer have done so in the context of a particular research question. This paper aims to provide an overview of four domains that have been studied using techniques amenable to elucidating the brain/behaviour interface: language, face processing, object permanence, and joint attention, with particular emphasis on studies focusing on early development. The importance of the unique role of development and the interplay between structure and function is stressed throughout. It is hoped that this review will serve as a catalyst for further thinking about the substantial gaps in our understanding of the relationship between brain and behaviour across development. Further, our aim is to provide ideas about candidate brain areas that are likely to be implicated in particular behaviours or cognitive domains.

“…The 8 years old group did not differ from the younger or older groups, suggesting that this is probably an age where the change is occurring in a more evident way or in most children, or both. The change in rate of learning at this time of life might be, at least in part, effect of the central executive development, and so of a progressively more strategic encoding of new information 24,25 . Also, it is possible to conceive that the enlargement of vocabulary as the child gets older, makes easier to encode and recall the lists: the memory nodes for the words being already in long-term memory, encoding is much more a matter of elevation of activation level, than that of formation of new nodes of memory 24 .…”

-The Rey Auditory Verbal Learning paradigm is worldwide used in clinical and research settings. There is consensus about its psychometric robustessness and that its various scores provide relevant information about different aspects of memory and learning. However, there are only a few studies in Brazil employing this paradigm and none of them with children. This paper describes the performance of 119 Brazilian children in a version of Rey´s paradigm. The correlations between scores showed the internal consistency of this version. Also, the pattern of results observed was very similar to that observed in foreign studies with adults and children. There was correlation between age in months and recall scores, showing that age affects the rhythm of learning. These results were discussed based on the information processing theory.KEY WORDS: memory, child, Rey auditory verbal learning, cognitive science, neuropsychology. desempenho de crianças brasileiras no paradigma de aprendizagem auditivo-verbal de reyResumo -O paradigma de aprendizagem auditivo-verbal de Rey é utilizado em todo o mundo, tanto em pesquisa quanto na clínica. Há consenso sobre sua robustez psicométrica e de que seus vários escores fornecem informações relevantes sobre diferentes aspectos da memória e da aprendizagem. No entanto, existem apenas alguns poucos estudos no Brasil envolvendo este paradigma e nenhum deles com crianças. Este artigo descreve o desempenho de 119 crianças brasileiras em uma versão do paradigma de Rey. As correlações entre escores mostraram a consistência interna desta versão. Além disso, o padrão de resultados encontrado foi muito similar àquele observado em estudos estrangeiros com adultos e crianças. Verificou-se correlação entre idade em meses e os escores de evocação, mostrando que a idade afeta o ritmo de aprendizagem. Estes resultados foram discutidos a partir da teoria do processamento da informação.

“…PET activation studies in normal subjects did not systematically show involvement of the hippocampus in episodic memory tasks. 68 69 The implication of the hippocampus in episodic memory is probably much more complex than previously thought and may not be systematically required. 70 It is worth recalling in this context that a typical PAS may develop despite an intact hippocampus if the lesion aVects other parts of the episodic memory (limbic) network-for example, the diencephalic area.…”

Objectives-To assess explicit memory and two components of implicit memory-that is, perceptual-verbal skill learning and lexical-semantic priming eVects-as well as resting cerebral blood flow (CBF) and oxygen metabolism (CMRO 2 ) during the acute phase of transient global amnesia. Methods-In a 59 year old woman, whose amnestic episode fulfilled all current criteria for transient global amnesia, a neuropsychological protocol was administered, including word learning, story recall, categorical fluency, mirror reading, and word stem completion tasks. PET was performed using the 15 O steady state inhalation method, while the patient still exhibited severe anterograde amnesia and was interleaved with the cognitive tests. Results-There was a clear cut dissociation between impaired long term episodic memory and preserved implicit memory for its two components. Categorical fluency was significantly altered, suggesting word retrieval strategy-rather than semantic memory-impairment. The PET study disclosed a reduced CMRO 2 with relatively or fully preserved CBF in the left prefrontotemporal cortex and lentiform nucleus, and the reverse pattern over the left occipital cortex. Conclusions-The PET alterations with patchy CBF-CMRO 2 uncoupling would be compatible with a migraine-like phenomenon and indicate that the isolated assessment of perfusion in transient global amnesia may be misleading. The pattern of metabolic depression, with sparing of the hippocampal area, is one among the distinct patterns of brain dysfunction that underlie the (apparently) uniform clinical presentation of transient global amnesia. The finding of a left prefrontal hypometabolism in the face of impaired episodic memory and altered verbal fluency would fit present day concepts from PET activation studies about the role of this area in episodic and semantic memory encoding/ retrieval. Likewise, the changes aVecting the lenticular nucleus but sparing the caudate would be consistent with the normal performance in perceptual-verbal skill learning. Finally, unaltered lexicalsemantic priming eVects, despite left temporal cortex hypometabolism, suggest that these processes are subserved by a more distributed neocortical network.
