Communication is not restricted to human language: indeed, most primates use vocal and facial expressions for social interactions and survival. Like humans, nonhuman primates are able to extract and interpret vocal features to gain knowledge about the speaker, such as its species, identity, body size and emotional state. Functional magnetic resonance imaging (fMRI) studies have identified brain areas dedicated to processing species-specific vocal signals (‘voice’ areas) in the anterior temporal lobe, and researchers have started to establish homologies between how the brains of primates process communication signals.

 

Nevertheless, it remains unclear how voices  are represented at the neuronal level. My research applies extracellular electrophysiology targeting the ‘voice’ area to investigate the encoding of vocal features at the resolution of single neurons.

 

I study the neural representation of voices by: (a) evaluating the organization and auditory encoding properties of neurons in the ‘voice’ area and (b) investigating the multisensory influence of face information on voice processing in the context of audiovisual communication. These complementary approaches will provide an integrated perspective on the neuronal representation of voices in a dedicated auditory area, and extend our understanding of how the primate brain processes vocal communication signals.

 

 

Research interests:

- Electrophysiology

- Auditory and sensory processing

- Neuronal coding

- Communication signals

- Neural networks and microcircuits

- Autism

 

Neuronal selectivity for conspecific voices in an fMRI voice-sensitive cluster

 

- There are specialized voice cells in the primate brain, that seem to have developed a different stimulus encoding strategy than face cells in the visual system

- A press release about our study

- Our publication featured by Faculty of 1000

 

Encoding of higher-level vocal features

 

- Neurons in the voice area represent many vocal features, and a distinct neuronal subpopulation is sensitive to caller identity

 

Multisensory interactions between voices and faces in the voice area

 

- Faces influence the auditory processing by voice area neurons, but sensitivity to voice/face congruency only emerges at the next sensory processing level

 

Encoding of acoustic components of vocalizations
