“…Precuneus activation has also been reported for auditory imagery (Yoo et al, 2001) and for the recognition of familiar sounds (Maeder et al, 2001) and voices (Nakamura et al, 2001)-as well as for recognition memory in general (Henson et al, 2000;Herath et al, 2001). Precuneal activity in the present study, thus, might alternatively be taken to suggest that earlier learned words elicit a greater recognition response in the brain.…”

Recently there has been a renewed interest in cognitive psychology on the effects of the age of word acquisition (AoA) on lexical processing. In particular, it is currently unclear whether AoA or word frequency are better predictors of word recognition. To date no study has investigated the neural bases of the AoA effect or attempted to dissociate it from word frequency. We report a visual and an auditory event-related fMRI experiment investigating the influence of AoA and word frequency on neural activity, and show that AoA modulates brain areas that are not influenced by word frequency. The precuneus was activated for early learned words across auditory and visual presentation modalities. Additional activity in the auditory cortex was observed specifically for the reading of early acquired words. Late learned words, in contrast, led to a selective activation increase in lateral inferior frontal areas. These findings support models that suggest that early and late learned words are represented differently in the brain. They further allow to specify the nature of the represenational differences, namely that early learned words are represented in the brain in a more sensory manner than late learned words.

“…They found that, in both hemispheres, the anterior temporal lobes were more active during speaker identification than during emotion identification. In a subsequent study (Nakamura et al 2001), the same group scanned normal volunteers with PET while they performed a familiar/unfamiliar decision task on voices from unknown persons and from their friends and relatives. A comparison task consisted of deciding whether the first phoneme of sentences pronounced by unfamiliar speakers was a vowel or a consonant.…”

Structural and functional asymmetries are present in many regions of the human brain responsible for motor control, sensory and cognitive functions and communication. Here, we focus on hemispheric asymmetries underlying the domain of social perception, broadly conceived as the analysis of information about other individuals based on acoustic, visual and chemical signals. By means of these cues the brain establishes the border between 'self ' and 'other', and interprets the surrounding social world in terms of the physical and behavioural characteristics of conspecifics essential for impression formation and for creating bonds and relationships. We show that, considered from the standpoint of single-and multi-modal sensory analysis, the neural substrates of the perception of voices, faces, gestures, smells and pheromones, as evidenced by modern neuroimaging techniques, are characterized by a general pattern of right-hemispheric functional asymmetry that might benefit from other aspects of hemispheric lateralization rather than constituting a true specialization for social information.

“…Several cortical regions, including the enthorinal cortex and the anterior part of the right temporal lobe, were found to be more active during the voice familiarity task. Moreover, cerebral blood flow in the right anterior temporal pole was correlated with the subjects' performance at a speaker identification task administered after scanning (Nakamura et al 2001). Belin & Zatorre (2003) used fMRI and a paradigm based on neuronal adaptation to investigate a putative representation of vocal signature in human auditory cortex.…”

Humans share with non-human primates a number of voice perception abilities of crucial importance in social interactions, such as the ability to identify a conspecific individual from its vocalizations. Speech perception is likely to have evolved in our ancestors on the basis of pre-existing neural mechanisms involved in extracting behaviourally relevant information from conspecific vocalizations (CVs). Studying the neural bases of voice perception in primates thus not only has the potential to shed light on cerebral mechanisms that may be-unlike those involved in speech perception-directly homologous between species, but also has direct implications for our understanding of how speech appeared in humans. In this comparative review, we focus on behavioural and neurobiological evidence relative to two issues central to voice perception in human and non-human primates: (i) are CVs 'special', i.e. are they analysed using dedicated cerebral mechanisms not used for other sound categories, and (ii) to what extent and using what neural mechanisms do primates identify conspecific individuals from their vocalizations?
