Lateralization of phonetic and pitch discrimination in speech processing.
TLDR
Processing changes in pitch produced activation of the right prefrontal cortex, consistent with the importance of right-hemisphere mechanisms in pitch perception.
Distributed processing of pain and vibration by the human brain
TLDR
Comparisons of pain and vibrotactile stimulation revealed that both stimuli produced activation in similar regions of SI and SII, regions long thought to be involved in basic somatosensory processing, which reflects the complex nature of pain.
Functional activation of the human frontal cortex during the performance of verbal working memory tasks.
TLDR
Evidence is provided regarding the role of the mid-dorsolateral frontal cortex in mnemonic processing that are in agreement with recent findings from work with non-human primates.
Neural mechanisms underlying melodic perception and memory for pitch
TLDR
It is concluded that specialized neural systems in the right superior temporal cortex participate in perceptual analysis of melodies; pitch comparisons are effected via a neural network that includes right prefrontal cortex, but active retention of pitch involves the interaction of right temporal and frontal cortices.
Multiple representations of pain in human cerebral cortex.
TLDR
It has now been demonstrated that painful heat causes significant activation of the contralateral anterior cingulate, secondary somatosensory, and primary somatoensory cortices.
Dissociation of human mid-dorsolateral from posterior dorsolateral frontal cortex in memory processing.
TLDR
These findings provide direct evidence that, just as the monkey brain, the human lateral frontal cortex is functionally heterogeneous and that comparable anatomical areas underlie similar functions in the two species.
Role of the human anterior cingulate cortex in the control of oculomotor, manual, and speech responses: a positron emission tomography study.
TLDR
The localization of output-specific rCBF changes within the human ACC is consistent with the known somatotopic organization of the cingulate cortex in the monkey, and it is tentatively proposed that the ACC participates in motor control by facilitating the execution of the appropriate responses and/or suppressing the Execution of the inappropriate ones.
The neural substrates underlying word generation: a bilingual functional-imaging study.
TLDR
The results suggest that common neural substrates are involved in within- and across-language searches and that the left inferior frontal region is activated irrespective of whether the search is guided by phonological or semantic cues.
PET studies of phonetic processing of speech: review, replication, and reanalysis.
TLDR
The findings support a model whereby articulatory processes involving a portion of Broca's area are important when phonetic segments must be extracted and manipulated, whereas left posterior temporal cortex is involved in perceptual analysis of speech.
Functional localization and lateralization of human olfactory cortex
TLDR
Significant cerebral blood flow increases at the junction of the inferior frontal and temporal lobes bilaterally, corresponding to the piriform cortex, and unilaterally, in the right orbitofrontal cortex are reported, indicating that a functional asymmetry exists in the human brain favouring the right Orbitofrontal area in olfaction.
