Neural organization for the long-term memory of paired associates
MOST of our long-term memories of episodes or objects are organized so that we can retrieve them by association. Clinical neuropsychologists assess human memory by the paired-associate learning test,… Expand

A syntactic specialization for Broca's area.
Despite numerous aphasia and functional imaging studies, the exact correlation between cortical language areas and subcomponents of the linguistic system has not been established. Here, we used… Expand

  • 4 November 2005
Language acquisition is one of the most fundamental human traits, and it is obviously the brain that undergoes the developmental changes. During the years of language acquisition, the brain not only… Expand

Brain activations during conscious self‐monitoring of speech production with delayed auditory feedback: An fMRI study
When a speaker's voice returns to one's own ears with a 200‐ms delay, the delay causes the speaker to speak less fluently. This phenomenon is called a delayed auditory feedback (DAF) effect. To… Expand

Learning Letters in Adulthood Direct Visualization of Cortical Plasticity for Forming a New Link between Orthography and Phonology
To identify which brain regions in adults show plasticity for learning letters, Hangul letters were experimentally associated with either speech sounds (HS condition) or nonspeech sounds (HN… Expand

From Perception to Sentence Comprehension: The Convergence of Auditory and Visual Information of Language in the Left Inferior Frontal Cortex
TLDR
We used functional magnetic resonance imaging to characterize cortical activation associated with sentence processing, thereby elucidating where in the brain auditory and visual inputs of words converge during sentence comprehension. Expand

Language-Related Activations in the Left Prefrontal Regions Are Differentially Modulated by Age, Proficiency, and Task Demands
It remains to be elucidated how cortical activations are modulated by factors of age, proficiency, and language task demands when mastering first language (L1) and a second language (L2). Using… Expand

Neural correlates of noncanonical syntactic processing revealed by a picture‐sentence matching task
It remains controversial whether the left inferior frontal gyrus subserves syntactic processing or short‐term memory demands. Here we devised a novel picture‐sentence matching task involving Japanese… Expand

Localization of D-aspartic acid in elongate spermatids in rat testis.
In the current study, localization of D-aspartic acid (D-Asp) in rat testis was studied by immunohistochemical and biochemical techniques. Immunohistochemical staining of this tissue using specific… Expand

Specialization in the Left Prefrontal Cortex for Sentence Comprehension
Using functional magnetic resonance imaging (fMRI), we examined cortical activation under syntactic decision tasks and a short-term memory task for sentences, focusing on essential properties of… Expand
