Clinical Neuropsychology What Is Clinical Neuropsychology?
Clinical Neuropsychology What is Clinical Neuropsychology? A Neuropsychologist is a licensed psychologist trained to examine the link between a patient’s brain and behavior. A Neuropsychologist will assess neurological, medical, and genetic disorders, psychiatric illness and behavior problems, developmental disabilities, and complex learning issues. UNC PM&R’s Neuropsychologists work with children, adolescents, and adults. The primary goal of this service is to utilize results of the evaluation to collaborate with the patient and develop a treatment plan and recommendations that best fit the patient’s needs. Patients who may benefit from a Neuropsychological Evaluation include those with: • A neurological disorder such as epilepsy, hydrocephalus, Parkinson’s disease, Alzheimer’s disease and other dementias, multiple sclerosis, or hydrocephalus • An acquired brain injury from concussion or more severe head trauma, stroke, hydrocephalus, lack of oxygen, brain infection, brain tumor, or other cancers • Other medical conditions that may affect brain functioning, such as chronic heart, lung, kidney, or liver problems, diabetes, breathing issues, lupus, or other autoimmune diseases • A neurodevelopmental disorder such as cerebral palsy, spina bifida, intellectual disabilities, learning difficulties, ADHD disorder, or autism spectrum disorder • Problems with or changes in thinking, memory, or behavior with no clear known cause What is the evaluation like? The evaluation will be tailored to The evaluation may last between 3-6 address the patient’s specific concerns hours and typically includes: about functioning, and can address 1.

Introduction to Neuroimaging
Introduction to Neuroimaging Janaina Mourao-Miranda • Neuroimaging techniques have changed the way neuroscientists address questions about functional anatomy, especially in relation to behavior and clinical disorders. • Neuroimaging includes the use of various techniques to either directly or indirectly image the structure or function of the brain. • Structural neuroimaging deals with the structure of the brain (e.g. shows contrast between different tissues: cerebrospinal fluid, grey matter, white matter). • Functional neuroimaging is used to indirectly measure brain functions (e.g. neural activity) • Example of Neuroimaging techniques: – Computed Tomography (CT), – Positron Emission Tomography (PET), – Single Photon Emission Computed Tomography (SPECT), – Magnetic Resonance Imaging (MRI), – Functional Magnetic Resonance Imaging (fMRI). • Among other imaging modalities MRI/fMRI became largely used due to its low invasiveness, lack of radiation exposure, and relatively wide availability. • Magnetic Resonance Imaging (MRI) was developed by researchers including Peter Mansfield and Paul Lauterbur, who were awarded the Nobel Prize for Physiology or Medicine in 2003. • MRI uses magnetic fields and radio waves to produce high quality 2D or 3D images of brain structures/functions without use of ionizing radiation (X- rays) or radioactive tracers. • By selecting specific MRI sequence parameters different MR signal can be obtained from different tissue types (structural MRI) or from metabolic changes (functional MRI).

The Creation of Neuroscience
The Creation of Neuroscience The Society for Neuroscience and the Quest for Disciplinary Unity 1969-1995 Introduction rom the molecular biology of a single neuron to the breathtakingly complex circuitry of the entire human nervous system, our understanding of the brain and how it works has undergone radical F changes over the past century. These advances have brought us tantalizingly closer to genu- inely mechanistic and scientifically rigorous explanations of how the brain’s roughly 100 billion neurons, interacting through trillions of synaptic connections, function both as single units and as larger ensem- bles. The professional field of neuroscience, in keeping pace with these important scientific develop- ments, has dramatically reshaped the organization of biological sciences across the globe over the last 50 years. Much like physics during its dominant era in the 1950s and 1960s, neuroscience has become the leading scientific discipline with regard to funding, numbers of scientists, and numbers of trainees. Furthermore, neuroscience as fact, explanation, and myth has just as dramatically redrawn our cultural landscape and redefined how Western popular culture understands who we are as individuals. In the 1950s, especially in the United States, Freud and his successors stood at the center of all cultural expla- nations for psychological suffering. In the new millennium, we perceive such suffering as erupting no longer from a repressed unconscious but, instead, from a pathophysiology rooted in and caused by brain abnormalities and dysfunctions. Indeed, the normal as well as the pathological have become thoroughly neurobiological in the last several decades. In the process, entirely new vistas have opened up in fields ranging from neuroeconomics and neurophilosophy to consumer products, as exemplified by an entire line of soft drinks advertised as offering “neuro” benefits. -
Strategies for Social Skills for Students with Autism Spectrum Disorder
National Association of Special Education Teachers AUTISM SPECTRUM DISORDER SERIES Strategies for Social Skills for Students with Autism Spectrum Disorder Introduction One of the most important areas for intervention for children with autism will be in the area of social skills development. Most students with ASD would like to be part of the social world around them. They have a need to interact socially and be involved with others. However, one of the defining characteristics of ASD is impairment in social interactions and social skills. Students with ASD have not automatically learned the rules of interaction with others, and they are unable to follow these unwritten rules of social behavior. This article will focus on this very important and relevant issue. Most students with ASD would like to be part of the social world around them. They have a need to interact socially and be involved with others. However, one of the defining characteristics of ASD is impairment in social interactions and social skills. Students with ASD have not automatically learned the rules of interaction with others, and they are unable to follow these unwritten rules of social behavior. Many people with ASD are operating on false perceptions that are rigid or overly literal. Recognizing these false perceptions can be very helpful in understanding the behavior and needs of these students in social situations. The misperceptions include: • rules apply in only a single situation • everything someone says must be true • when you do not know what to do, do nothing. Imagine how overly literal misconceptions could seriously limit social interaction. -

Empathy, Mirror Neurons and SYNC
Mind Soc (2016) 15:1–25 DOI 10.1007/s11299-014-0160-x Empathy, mirror neurons and SYNC Ryszard Praszkier Received: 5 March 2014 / Accepted: 25 November 2014 / Published online: 14 December 2014 Ó The Author(s) 2014. This article is published with open access at Springerlink.com Abstract This article explains how people synchronize their thoughts through empathetic relationships and points out the elementary neuronal mechanisms orchestrating this process. The many dimensions of empathy are discussed, as is the manner by which empathy affects health and disorders. A case study of teaching children empathy, with positive results, is presented. Mirror neurons, the recently discovered mechanism underlying empathy, are characterized, followed by a theory of brain-to-brain coupling. This neuro-tuning, seen as a kind of synchronization (SYNC) between brains and between individuals, takes various forms, including frequency aspects of language use and the understanding that develops regardless of the difference in spoken tongues. Going beyond individual- to-individual empathy and SYNC, the article explores the phenomenon of syn- chronization in groups and points out how synchronization increases group cooperation and performance. Keywords Empathy Á Mirror neurons Á Synchronization Á Social SYNC Á Embodied simulation Á Neuro-synchronization 1 Introduction We sometimes feel as if we just resonate with something or someone, and this feeling seems far beyond mere intellectual cognition. It happens in various situations, for example while watching a movie or connecting with people or groups. What is the mechanism of this ‘‘resonance’’? Let’s take the example of watching and feeling a film, as movies can affect us deeply, far more than we might realize at the time. -
Neuropsychology of Facial Expressions. the Role of Consciousness in Processing Emotional Faces
Neuropsychology of facial expressions. The role of consciousness in processing emotional faces Michela Balconi Department of Psychology, Catholic University of the Sacred Heart, Milano, Italy [email protected] Abstract Neuropsychological studies have underlined the significant presence of distinct brain correlates deputed to analyze facial expression of emotion. It was observed that some cerebral circuits were considered as specific for emotional face comprehension as a func- tion of conscious vs. unconscious processing of emotional information. Moreover, the emotional content of faces (i.e. positive vs. negative; more or less arousing) may have an effect in activating specific cortical networks. Between the others, recent studies have explained the contribution of hemispheres in comprehending face, as a function of type of emotions (mainly related to the distinction positive vs. negative) and of specific tasks (comprehending vs. producing facial expressions). Specifically, ERPs (event-related potentials) analysis overview is proposed in order to comprehend how face may be processed by an observer and how he can make face a meaningful construct even in absence of awareness. Finally, brain oscillations is considered in order to explain the synchronization of neural populations in response to emotional faces when a conscious vs. unconscious processing is activated. Keywords: Face; Consciousness; Brain; Brain oscillations; ERPs 1. Face and consciousness Rapid detection of emotional information is highly adaptive, since it pro- vides critical elements on environment and on the attitude of the other people (Darwin, 1872; Eimer & Holmes, 2007).
