TLDR
The results support the notion that self-related processes are not necessarily engaged during sensory perception and can be actually suppressed, and show a complete segregation between the two patterns of activity.About:

Brain system for mental orientation in space, time, and person.
TL;DR: Using high-resolution functional MRI scanning in individual subjects, it is shown that mental orientation in space, time, and person produces a sequential posterior–anterior pattern of activity in each participant’s brain, highlighting the relation betweenmental orientation in these domains.

fMRI reveals reciprocal inhibition between social and physical cognitive domains
Anthony I. Jack,Abigail J. Dawson,Katelyn L. Begany,Regina L. Leckie,Kevin P. Barry,Angela Hein Ciccia,Abraham Z. Snyder +6 more
TL;DR: There is a physiological constraint on the ability to simultaneously engage two distinct cognitive modes, and two types of problem-solving task are identified: tasks requiring social cognition and tasks requiring physical cognition, i.e., reasoning about the causal/mechanical properties of inanimate objects.

Data-driven clustering reveals a fundamental subdivision of the human cortex into two global systems
TL;DR: A hypothesis-free, unsupervised two-class clustering algorithm (k-means) was applied to a large set of fMRI data and confirmed that the intrinsic-extrinsic subdivision constitutes a fundamental cortical divide.
Journal ArticleDOI
Motor imagery: a window into the mechanisms and alterations of the motor system.
TL;DR: How motor imagery research has advanced knowledge of behavioral and neural aspects of action control, both in healthy subjects and clinical populations is reviewed and how motor imagery can provide new insights in a poorly understood psychopathological condition: conversion paralysis is illustrated.

Abnormal network connectivity in frontotemporal dementia: Evidence for prefrontal isolation

TL;DR: The present findings support a theory of FTD as a disorder of frontolimbic disconnection leading to unconstrained prefrontal connectivity, and suggest prefrontal hyperconnectivity may represent a compensatory response to the absence of affective feedback during the planning and execution of behavior.

The Principles of Psychology
TL;DR: For instance, the authors discusses the multiplicity of the consciousness of self in the form of the stream of thought and the perception of space in the human brain, which is the basis for our work.

A default mode of brain function.
Marcus E. Raichle,Ann Mary MacLeod,Abraham Z. Snyder,William J. Powers,Debra A. Gusnard,Gordon L. Shulman +5 more
TL;DR: A baseline state of the normal adult human brain in terms of the brain oxygen extraction fraction or OEF is identified, suggesting the existence of an organized, baseline default mode of brain function that is suspended during specific goal-directed behaviors.

Descartes' Error: Emotion, Reason, and the Human Brain
TL;DR: The authors argued that rational decisions are not the product of logic alone - they require the support of emotion and feeling, drawing on his experience with neurological patients affected with brain damage, Dr Damasio showed how absence of emotions and feelings can break down rationality.
