- Overview
-
Dr. Herdman’s research program focuses on understanding the brain dynamics that underlie psychological phenomena involved in auditory and visual perceptions, audiovisual integration, attention, and language. He uses behavioural and electrophysiological (EEG & MEG) measures to study fundamental principles of these systems and how they develop. Dr. Herdman’s former and current research projects include evaluating the validity and utility of clinical electrophysiological methods for assessing infant and adult hearing. Another major research area is on advancing and validating neuroimaging methods for EEG and MEG. Dr. Herdman is particularly fascinated by how a human brain functions and communicates across multiple dimensions (space, time, and frequency) and how such communication is altered by experience as a brain develops its abundant abilities.

Central Auditory Processing
A new line of research in the BRANE lab is investigating the use of electrophysiological responses in assessing central auditory processing. One specific aim is to evaluate the accuracy and precision of using cortical auditory evoked potentials (CAEPs) to estimate behavioural gap-detection thresholds (McDonald & Herdman, in revision; Angel & Herdman, in revision). This will help determine if we can use CAEPs as an objective estimate of auditory temporal resolution. These studies are needed to lay the foundation in order to proceed to evaluate the validity of using CAEPs in testing individuals with central auditory processing disorders.Auditory Evoked Potentials
This research investigates auditory evoked potentials (AEPs) from the brainstem to the cortex in the pediatric population. Our main objectives are to fill in the gaps in our understanding of brainstem AEPs in infants and children in order to improve current clinical assessment tools and protocols, and to evaluate the reliability of using cortical AEPs to assess hearing in infants and children. Results from these studies will improve the accuracy of diagnostic assessment of hearing capacity to help inform intervention and treatment decisions in a timely fashion.Auditory Selective Attention
Our work on children’s selective attention has provided insights into the neural underpinnings of how socioeconomic gradients can alter the developing brain (D’Angiulli, Herdman, Stapells, and Hertzman, Neuropsychology, 2008). Our results demonstrated that children from low-socioeconomic families recruit a more frontally-mediated system to perform auditory selective attention, whereas children from high-socioeconomic families use more of an auditory-dependent network. Follow-up research showed that selective attention appears to mature from higher-to-lower stages of information processing (Herdman, Brain Topography, 2011). This could have potential implications for understanding neural development of children’s selective attention.Neuroimaging Methodology (EEG/MEG)
In addition to our work in perceptual and cognitive areas, we also work as methodologists in electrophysiology and neuroimaging. We develop neuroimaging tools to help answer research questions from multiple disciplines (Moiseev et al., 2011; Moiseev & Herdman, 2013; Herdman et al., 2018). We also use functional connectivity analyses to capture the exciting changes in neural dynamics. Such methods used to study these networks are now being applied to neuroimaging data to provide deeper insights into unlocking the neural codes for perception and cognition. We are excited to be working in this area, which is rapidly receiving scientific interest from many researchers around the world.Visual Experience
One main objective of BRANE lab’s basic scientific research is to investigate the normal brain functions related to visual expertise. We use reading as a model of visual expertise and have shown that brain responses to unfamiliar pseudoletters are delayed in an object processing network with additional findings of greater gamma-band activity and delayed functional communication within this network for pseudoletter as compare to letters (Herdman, J.Clin.NeuroPhys. 2011; Herdman & Takai, Frontiers Human Neuroscience 2013; Bann & Herdman, Frontiers Human Neuroscience, 2016). Collectively, we interpreted these results as indicators that experience with letters modifies the visual network by shifting it to be a faster, more holistic processor for letters than for pseudoletters in a similar manner to that shown to be used for processing faces as compared to inverted faces.GrantsKids Brain Health Network (2018-2024), “Intelligent solutions for atypical auditory processing in children with neurodevelopmental disorders.” [PI = E.
