In this opinion article we discuss how the temporal response properties of neurons in auditory cortex, as well as their patterns of connectivity, may give rise to functional distinctions in auditory processing.

Perception involves integration of multiple dimensions that often serve overlapping, redundant functions, e.g. pitch, duration and amplitude in speech and music. Individuals tend to prioritize these dimensions differently using stable, individualized perceptual strategies. Here we show that these strategies are related to perceptual abilities.

We use a novel fMRI paradigm to examine neural activity during naturalistic, real-time face-to-face spoken interactions and resting state, in participants with autism and matched controls. We also discuss the study in our recent review.

Using a novel fMRI paradigm in which two people talk together in real-time, we show that joint speech (as in group chants and prayers) recruits additional right hemisphere regions outside the classic speech production network. Additionally, we found that a neural marker of self-produced speech, suppression of sensory cortices, did not occur during joint synchronized speech, suggesting that joint synchronized behavior may alter self-other distinctions in sensory processing.

Here we show that native speakers of Mandarin—a language where pitch is very important—rely heavily on pitch to process other kinds of sounds: They weight pitch highly when processing (second language) English speech, when processing music, and they even struggle to ignore pitch when asked to attend to something else. The results demonstrate a new way that characteristics of one's native language influence perception.

Congenital amusia is characterized by unreliable pitch perception. Amusics perceive speech well, but they use an atypical strategy—they downweight pitch cues to adjust for their deficit. Here we demonstrate a possible neural basis: reduced functional connectivity between right hemisphere pitch-related regions and left hemisphere language-associated regions.

We review the autism resting state fMRI literature, highlight the potential role of the thalamus and striatum in autism, and emphasize the need for studies that directly compare scanning during multiple cognitive states in addition to the resting-state.

We outline the exciting ways virtual reality can be used to study language, as well as the pitfalls.

We used fMRI to show that whether or not someone is looking at your when they're talking (their gaze direction) affects brain activity in left hemisphere areas that process speech.

By measuring frequency following responses with EEG, we show that difficulty learning a second language in adulthood may be partly due to auditory perception problems.

We find, using 7T fMRI, that reading sentences with social-emotional words activates regions across the 'social brain' network. Reading sentences with inanimate object words activates object/scene recognition regions. We suggest it is important to take semantic content into account when studying reading.

We show that, through associations between left-right space and emotion, the hands we use to type words on a keyboard may slowly shape the emotional associations of those words.

English uses front-back spatial metaphors to talk about time. Do English speakers think about this time way? Here we use evidence from hand gestures to show that English speakers use the front-back axis to gesture about time deliberately, but prefer a left-right axis when gesturing spontaneously.

Speakers associate positive messages more strongly with dominant hand gestures and negative messages with non-dominant hand gestures, revealing a hidden link between action and emotion.

My PhD was completed jointly at the National Institute of Mental Health (NIMH/NIH) and the UCL Institute of Cognitive Neuroscience.
Now I work at Birkbeck University of London, funded by an Early Career Fellowship from the Leverhulme Trust with ongoing honorary appointments at UCL and NIMH. A portion of my research is also funded by the Society for Education, Music and Psychology Research (SEMPRE).
