Eric Halgren mostly deals with Neuroscience, Temporal lobe, Electroencephalography, Magnetoencephalography and Functional magnetic resonance imaging. His Electroencephalography study incorporates themes from Frontal lobe, Premovement neuronal activity, Brain mapping and Epilepsy. In Magnetoencephalography, Eric Halgren works on issues like Repetition priming, which are connected to Modality and Primary sensory areas. He has included themes like Temporal cortex, Semantic memory and Cognitive neuroscience of visual object recognition in his Functional magnetic resonance imaging study. His Visual cortex research is multidisciplinary, incorporating elements of Orbitofrontal cortex and Human brain. His Statistical parametric mapping research integrates issues from Artificial intelligence and Pattern recognition.
