The hybrid nature of task-evoked activity: Inside-out neural dynamics in intracranial EEG and Deep Learning

Abstract: A.AbstractThe standard approach in neuroscience research infers from the external stimulus (outside) to the brain (inside) through stimulus-evoked activity. Recently challenged by Buzsáki, he advocates the reverse; an inside-out approach inferring from the brain’s activity to the neural effects of the stimulus. If so, stimulus-evoked activity should be a hybrid of internal and external components. Providing direct evidence for this hybrid nature, we measured human intracranial stereo-electroencephalography (sE… Show more

“…Further lines of evidence include: (iv) the rest of the brain's "dark energy" (80-90%) may, by itself, not necessarily or always be accompanied by specific cognitive functions including internally-oriented cognition (Raichle and others., 2001;Raichle and Menon, 2006;Raichle, 2015a and b); (v) involvement of the DMN in externally-oriented cognition like attention to external stimuli (Andrews-Hanna, 2012;Raichle and others., 2001) and complex external naturalistic stimuli others., 2015, 2017;Simony and others., 2016);(vi) DMN and both internally-and externally-oriented cognition in various psychiatric disorders (Anticevic and others., 2012;Northoff and Gomez-Pilar, 2020;Scalabrini and others., 2020).…”

“…Psychiatric disorders like schizophrenia, bipolar disorder (BD), and major depressive disorder (MDD) can be characterized by abnormal shifts in the balance of internally-and externally-oriented cognition. For instance, internally-oriented cognition dominates in schizophrenia delusion and hallucination where it is confused with externally-oriented cognition (Northoff and Gomez-Pilar, 2020). Investigation of GS demonstrated abnormal decreases in GS topography in specifically sensory and motor cortex in schizophrenia while it was abnormally increased in association cortex like prefrontal cortex (Yang and others., 2017) -this may reflect the abnormal shift towards internally-oriented cognition and its confusion with externallyoriented cognition in these patients.…”
