Mirror Neurons and Their Reflections
Open Access Library Journal Mirror Neurons and Their Reflections Mehmet Tugrul Cabioglu1, Sevgin Ozlem Iseri2 1Department of Physiology, Faculty of Medicine, Baskent University, Ankara, Turkey 2Department of Clinical Biochemistry, Faculty of Medicine, Hacettepe University, Ankara, Turkey Received 23 October 2015; accepted 7 November 2015; published 12 November 2015 Copyright © 2015 by authors and OALib. This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Human mirror neuron system is believed to provide the basic mechanism for social cognition. Mirror neurons were first discovered in 1990s in the premotor area (F5) of macaque monkeys. Besides the premotor area, mirror neuron systems, having different functions depending on their locations, are found in various cortical areas. In addition, the importance of cingulate cortex in mother-infant relationship is clearly emphasized in the literature. Functional magnetic resonance imaging, electroencephalography, transcortical magnetic stimulation are the modalities used to evaluate the, activity of mirror neurons; for instance, mu wave suppression in electroencephalo- graphy recordings is considered as an evidence of mirror neuron activity. Mirror neurons have very important functions such as language processing, comprehension, learning, social interaction and empathy. For example, autistic individuals have less mirror neuron activity; therefore, it is thought that they have less ability of empathy. Responses of mirror neurons to object-directed and non-object directed actions are different and non-object directed action is required for the activa- tion of mirror neurons. Previous researchers find significantly more suppression during the ob- servation of object-directed movements as compared to mimed actions. -
Clinical Neurophysiology (CNP) Section Resident Core Curriculum
American Academy of Neurology Clinical Neurophysiology (CNP) Section Resident Core Curriculum 9/7/01 Definition of the Subspecialty of Clinical Neurophysiology The subspecialty of Clinical Neurophysiology involves the assessment of function of the central and peripheral nervous system for the purpose of diagnosing and treatment of neurologic disorders. The CNP procedures commonly used include EEG, EMG, evoked potentials, polysomnography, epilepsy monitoring, intraoperative monitoring, evaluation of movement disorders, and autonomic nervous system testing. The use of CNP procedures requires an understanding of neurophysiology, clinical neurology, and the findings that can occur in various neurologic disorders. The following are the recommended CORE curriculum for residents re CNP. Basic Neurophysiology: Membrane properties of nerve and muscle potentials (resting, action, synaptic, generator), ion channels, synaptic transmission, physiologic basis of EEG, EMG, evoked potentials, sleep mechanisms, autonomic disorders, epilepsy, neuromuscular diseases, and movement disorders Anatomic Substrates of EEG, EMG, evoked potentials, sleep and autonomic activity Indications: Know the indications for and the interpretation of the various CNP tests in the context of the clinical problem.

The Neural Basis of the Dynamic Unconscious
Neuropsychoanalysis, 2011, 13 (1) 5 The Neural Basis of the Dynamic Unconscious Heather A. Berlin (New York) A great deal of complex cognitive processing occurs at the unconscious level and affects how humans behave, think, and feel. Sci- entists are only now beginning to understand how this occurs on the neural level. Understanding the neural basis of consciousness requires an account of the neural mechanisms that underlie both conscious and unconscious thought, and their dynamic interac- tion. For example, how do conscious impulses, thoughts, or desires become unconscious (e.g., repression) or, conversely, how do unconscious impulses, desires, or motives become conscious (e.g., Freudian slips)? Research taking advantage of advances in technologies, like functional magnetic resonance imaging, has led to a revival and re-conceptualization of some of the key concepts of psychoanalytic theory, but steps toward understanding their neural basis have only just commenced. According to psychoanalytic theory, unconscious dynamic processes defensively remove anxiety-provoking thoughts and impulses from consciousness in re- sponse to one’s conflicting attitudes. The processes that keep unwanted thoughts from entering consciousness include repression, suppression, and dissociation. In this literature review, studies from psychology and cognitive neuroscience in both healthy and patient populations that are beginning to elucidate the neural basis of these phenomena are discussed and organized within a con- ceptual framework. Further studies in this emerging field at the intersection of psychoanalytic theory and neuroscience are needed. Keywords: unconscious; psychodynamic; repression; suppression; dissociation; neural “Nothing is so difficult as not deceiving oneself.” 1998a). Early psychodynamic theorists attempted to Ludwig Wittgenstein [1889–1951] explain phenomena observed in the clinic, but lat- er cognitive scientists used computational models of the mind to explain empirical data. -

What looks like an oversized walnut made of soft, grayish-pink cheese but contains the equivalent of 100 trillion tiny calculators (Restak, Brain 27)? What, according to James Watson, co-discoverer of the helical structure of DNA, is "the most complex thing we have yet discovered in our universe" (qtd. in Begley 66)? To all four of these intriguing questions there is but one surprising answer: the human brain. This miraculous organ is remarkable in its structure, its function, and its chemical Doe 2 composition. What is the brain? According to Richard Restak, the human brain is the master control center of the body. The brain constantly receives information from the senses about conditions both inside the body and outside it. The brain rapidly analyzes this information and then sends out messages that control body functions and actions. ("Brain" 561) According to Tether, the brain is divided into three main parts: the cerebrum, the cerebellum, and the brain stem (421).
