“…However, numerous human voices (friends, celebrities) were also effective inducers. Voice-selective cortical areas have been documented in superior temporal cortex (Belin, Lafaille, Ahad, & Pike, 2000;Petkov et al, 2008) and insular cortex (Remedios, Logothetis, & Kayser, 2009). These areas may show an increased connectivity to gustatory Lexical-gustatory synesthesia 13 cortex in PS independently of the hyperconnectivity between language cortex and gustatory cortex.…”

In developmental lexical-gustatory synesthesia, specific words (inducers) can trigger taste perceptions (concurrents) and these synesthetic associations are generally stable. We describe a case of multilingual lexical-gustatory synesthesia for whom some synesthesias were bidirectional as some tastes also triggered auditory word associations. Evoked concurrents could be gustatory but also tactile sensations. In addition to words and pseudowords, many voices were effective inducers, suggesting increased connections between cortical taste areas and both voice-selective and language-selective areas. Lasting changes in some evoked tastes occurred during childhood suggesting that some plasticity can be present after the initial learning of associations. Inducers were often linked to taste concurrents phonologically or semantically, but also through identifiable childhood episodes (persons or events). Several inducers were phonologically linked to episodic inducers suggesting a process of secondary acquisition for many inducers. Implications of these observations are discussed.

“…Recent findings, however, suggest that there are voice-specific areas in the human (Belin et al 2000) and macaque (Poremba 2006;Petkov et al 2008) brain and that these areas are organized in an asymmetrical way. The different types of vocal information are processed in partially dissociated functional pathways and the parameters of voice, such as pitch, loudness, spectral content, amplitude envelope, formants, prosody, and accent seem to have specific neural modules dedicated to their analysis which are often lateralized.…”

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 recent studies in nonhuman primate neurophysiology, inspired by work on primate vocalizations, demonstrate the value of a research programme that tests for language-like processing in primates and other animals (e.g. Ghazanfar & Santos 2004;Gifford et al 2005;Belin 2006;Ghazanfar et al 2008;Petkov et al 2008).…”

The central importance of information in studies of animal communication

Keywords:animal communication animal signal information information transmission language meaningThe concept of information plays a central role in studies of animal communication. Animals' responses to the calls of different individuals, to food calls, alarm calls, and to signals that predict behaviour, all suggest that recipients acquire information from signals and that this information affects their response. Some scientists, however, want to replace the concept of information with one based on the 'manipulation' of recipients by signallers through the induction of nervous-system responses. Here we review both theory and data that argue against hypotheses based exclusively on manipulation or on a fixed, obligatory link between a signal's physical features and the responses it elicits. Results from dozens of studies indicate that calls with 'arousing' or 'aversive' features may also contain information that affects receivers' responses; that acoustically similar calls can elicit different responses; acoustically different calls can elicit similar responses; and 'eavesdropping' animals respond to the relationship instantiated by signal sequences. Animal signals encode a surprisingly rich amount of information. The content of this information can be studied scientifically.
