Doctoral Research Seminar on: "Investigating single neuron activity from humans during naturalistic, continuous stimulation", by Alana Irene Darcher, Tamara Müller, Chair for Computational Neuroengineering/ TUM

Abstract: There is a growing body of evidence that single neurons reliably code for discrete concepts, such as a person’s face or a type of landmark. A large portion of this work has been done using presentations of isolated stimuli, and it is unclear how neural populations handle conceptual information in a naturalistic setting. To address this question, we analyzed a dataset of single unit recordings from the medial temporal lobe (MTL) of human patients with intractable epilepsy as they watched a full-length commercial film. We developed a data processing pipeline and performed a series of exploratory analyses to investigate the emergence of conceptual information in the MTL. We examined the sensitivity of neural activity to raw visual signals, and the changes in firing patterns concurrent with features isolated from the movie presentation and the consistency of such changes across time and feature presentations.
