Intrinsic neuronal diversity as a substrate for cortical area specialization in primate vision

M. Feyerabend, S. Pommer, Samuel A. Mestern, M. S. Jimenez-Sosa et autres

In primates, primary visual cortex (V1) circuits support early visual processing, whereas in the lateral prefrontal cortex (LPFC), they support higher-order computations. Here, we characterized the intrinsic electrophysiological (e)-properties and morphology of excitatory (EXC), fast-spiking inhibitory (FSI), and non-fast-spiking inhibitory (NFSI) neurons …

Perceptual rhythms by phase-aligned perceptual performance peaks across trials

Tobias Schoeberl, Stefan Treue

Perceptual processing may rhythmically alternate. There is a line of evidence from dense sampling psychophysics supporting this claim: In such studies, performance in visual target detection or discrimination is repeatedly tested at various fine-grained time intervals relative to a reference event. This …

Multivariate Transfer Entropy Quantifies Information Transfer Between Dyadic Partners During Real-Time Perceptual Decision-Making

Juan Pablo Fiorenza, Vera Gnass, Felix Schneider, Alexander Gail et autres

1 Abstract Many social behaviours unfold continuously in time, yet most studies of social influence rely on discrete, trial-based paradigms. To quantify how humans actually integrate sensory and social signals during ongoing perceptual decision-making we here apply an information-theoretic analysis to data …

Temporal concentration and phase synchronization in phase-amplitude coupling

Marjan Nosouhi, Stefan Treue, Moein Esghaei

Introduction Neural oscillations are rhythmic patterns of electrical activity generated by groups of neurons. These oscillations occur at different frequencies, ranging from slow rhythms, such as theta (4–8 Hz) to faster rhythms, like gamma (30–200 Hz). Phase-amplitude coupling (PAC) is a fundamental …

Advancing preference testing in humans and animals

Dana Pfefferle, Steven Roger Talbot, Pia Kahnau, Lauren C. Cassidy et autres

Preference tests help to determine how highly individuals value different options to choose from. During preference testing, two or more options are presented simultaneously, and options are ranked based on the choices made. Presented options, however, influence each other, where the amount …

Dyadic Interaction Platform: A novel tool to study transparent social interactions

Sebastian Isbaner, Raymundo Báez-Mendoza, Ricarda Bothe, Anna Fischer et autres

Studies of social cognition examine how organisms process and act on the presence, intentions, actions, and behavioural outcomes of others in social contexts. Many real-life social interactions unfold during direct face-to-face contact and rely on immediate, time-continuous feedback about mutual behaviour and …

Spike frequency adaptation in primate lateral prefrontal cortex neurons results from interplay between intrinsic properties and circuit dynamics

Nils A. Koch, Benjamin W. Corrigan, Michael Feyerabend, Roberto A. Gulli et autres

Cortical neurons in brain slices display intrinsic spike frequency adaptation (I-SFA) to constant current inputs, while extracellular recordings show extrinsic SFA (E-SFA) during sustained visual stimulation. Inferring how I-SFA contributes to E-SFA during behavior is challenging due to the isolated nature of …

Bilateral Field Advantage of Spatial Attention in Macaque Lateral Prefrontal Cortex

Maryam Nouri Kadijani, Theda Backen, Kaustubh Manchanda, Sandeep K. Mody et autres

Allocating visual attention to behaviorally relevant stimuli is easier when distractors are in the opposite visual hemifield relative to when they are in the same hemifield. The neural mechanisms underlying this bilateral field advantage remains unclear. We documented this effect in two …

Single neuron diversity supports area functional specialization along the visual cortical pathways

Michael Feyerabend, Stefan Pommer, MS Jimenez-Sosa, Jenifer Rachel et autres

Abstract Humans and other primates have specialized visual pathways composed of interconnected cortical areas. The input area V1 contains neurons that encode basic visual features, whereas downstream in the lateral prefrontal cortex (LPFC) neurons acquire tuning for novel complex feature associations. It …
