NeuroReport 5, 2381-2384 (1994) WHEN two concurrent sensorimotor tasks require separate responses, selection of the first response generally delays selection of the second. Dual-task performance was examined in four patients who had undergone surgical transection of the forebrain commissures including the corpus callosum. One light flash was presented to each visual field in succession, and pat...

Humans are the most adaptable species on this planet, able to live in vastly different environments on Earth. Space represents the ultimate frontier and a true challenge to human adaptive capabilities. As a group, astronauts and cosmonauts are selected for their ability to work in the highly perilous environment of space, giving their best. Terrestrial research has shown that human cognitive an...

Whether the neuronal encoding of number is linear or logarithmic divides cognitive neuroscientists working on mathematical cognition. Recordings from the prefrontal cortex of the monkey support the logarithmic hypothesis. Similarities between number and the coding of other quantities are also beginning to become apparent.

The neural basis of auditory perception can be investigated non-invasively by recording event-related brain potentials (ERPs) during auditory stimulation.1 ERPs can be conceptualized as a sequence of components each with its own set of neural generators and reflecting different psychological functions.2 The ERP component termed the mismatch negativity (MMN) reflects a pre-attentive auditory dev...

In event-related potentials (ERPs) studies, recognition memory is associated with two positivities: one over parietal regions, and one over frontal regions. With nameable neutral stimuli, such as words or common objects, the parietal effect is usually left lateralized, and the frontal effect is usually right lateralized. We investigated the lateralization of these effects for nonnameable emotio...

We outline a framework of multilevel neurocognitive mechanisms that 1 incorporates representation and computation.We argue that paradigmatic explanations 2 in cognitive neuroscience fit this framework and thus that cognitive neuroscience con3 stitutes a revolutionary break from traditional cognitive science. Whereas traditional 4 cognitive scientific explanations were supposed to be distinct an...

Cognitive neuropsychiatry (C.N.P) embodies a logical and hypothetically driven method to justify scientific(i.e., clinical) psychopathologies regarding discrepancies usual mental—mind mechanisms. An involvement through neuronal (neuronic) substrates-of-impaired cognitive processes connects CNP the fundamental-neuroscience. The advent of C.N.P.3 decades ago(~1990) demonstrates increasing reconci...

A major issue in cognitive science concerns how phonological, lexical and conceptual knowledge about words is represented in the human brain. Clues for the relevant linguistic categories have been sought in patients with brain lesions and in processing differences for various word categories using positron emission tomography (PET) and electrical brain activity. One useful tool in the physiolog...

It is with a sense of excitement that we launch this new ournal. This feeling reflects not only an excitement about he field—the rapidly expanding body of knowledge about rain development—but also an enthusiastic anticipation bout the opportunities for this journal to contribute to the rowth and maturation of the rapidly emerging field. At the most straightforward level, the journal can proide ...
