What does Medial Frontal Cortex Signal During Behavior? Insights from Behavioral Neurophysiology, Volume 158 addresses and highlights a question that has remained central to cognitive and systems neuroscience since its inception, namely, what does the medial frontal cortex do? With insights from 17 of the fields leading teams of scientists, this volume attempts to address this question covering several topics with chapters including What do single unit responses in dorsal anterior cingulate cortex mean?, Social Processing by the Primate Medial Frontal Cortex, Medial frontal cortex and the temporal control of action, The midcingulate cortex and temporal integration, and more. Additional chapters cover The anterior cingulate cortex and event-based modulation of autonomic states, Integration of value and action in medial prefrontal neural systems, Secondary motor cortex: broadcasting and biasing animal's decisions through long-range circuits, The prefrontal cortex in social cognition, Representing task strategies in the medial prefrontal cortex, Prefrontal contributions to action control in rodents, From affective to cognitive processings: functional organization of the medial frontal cortex, and much more.
