Modular subdivisions of dolphin insular cortex: does evolutionary history repeat itself?
March 1, 1998... INTRODUCTION The notion that the neocortex is divided into functional parts was popularized almost a century ago by Brodmann (1909). Architectonic analysis of cerebral cortex in a variety of mammals led Brodmann to divide the neocortex into...

Contribution of human prefrontal cortex to delay performance.
March 1, 1998... INTRODUCTION One of the main functions of the attentional system is to enable cognitive processing to focus on significant stimulus attributes while ignoring or inhibiting irrelevant aspects of the stimulus. The inability to accomplish this...

Toward a functional analysis of the basal ganglia.
March 1, 1998... INTRODUCTION Because motor disability is the cardinal clinical feature of basal ganglia disease, the basal ganglia have long been thought of as part of the motor system. Neuroanatomical data over the last decade and more have indicated,...

Self-organization of binocular disparity tuning by reciprocal corticogeniculate interactions.
March 1, 1998... INTRODUCTION The rapid processing of binocular disparity information requires highly tuned disparity-selective neural responses, yet at birth infants show only a coarse level of stereopsis (Birch, Gwiazda, & Held, 1983; Blakemore, Hawken, &...

Neural site of the redundant target effect: electrophysiological evidence.
March 1, 1998... INTRODUCTION It is well established that button-press responses are faster for redundant signals than for similar single signals. Evidence for this phenomenon, known as the RTE, comes from experiments using both bimodal (visual-acoustic) and...

Cortical-hippocampal auditory processing identified by magnetoencephalography.
March 1, 1998... INTRODUCTION Event-related potentials (ERPs) have been extensively investigated in an effort to elucidate the brain mechanism underlying cognitive processing (Desmedt, Debrecker, & Manil, 1965; Sutton, Braren, Zubin, & John, 1965; Walter,...

Encapsulation of implicit and explicit memory in sequence learning.
March 1, 1998... INTRODUCTION Memory is not a single faculty but is composed of multiple separate abilities (Schacter, 1987; Squire, 1992; Tulring, 1985; Weiskrantz, 1990). One major distinction contrasts declarative (explicit) memory, which supports conscious...

Event-related brain potentials and case information in syntactic ambiguities.
March 1, 1998... INTRODUCTION Parsing and Garden-Path Sentences In order to successfully understand spoken or written language, different types of information, linguistic as well as nonlinguistic, have to be combined to derive the message that an utterance...

The neurology of empty categories: aphasics' failure to detect ungrammaticality.
March 1, 1998... INTRODUCTION Current neurological modeling of language perception has syntax located anteriorly in the left cerebral hemisphere, and semantics and the lexicon are posteriorly represented - located temporo-parietally around the Sylvian fissure...
