Keeping it simple: the consultation as a journey
Roger Neighbour in The Inner Consultation, 2018
This chapter is the first step in reducing the complexities of the consultation to manageable proportions. The key concepts of some important models of the consultation can be condensed into a simple metaphor of 'the consultation as a journey'. The consultation becomes no longer a checklist of things to do and points to cover, but rather a short series of places to get to, one after the other, and in the practitioner’s own way. The chapter shows a way of thinking about the consultation which is powerful enough to give the practitioner a sense of purpose and direction, but at the same time simple enough to be unobtrusive. It presents it simultaneously in two forms – in language that the analytical Organiser in the left hemisphere can readily learn, and in a metaphor which the Responder can intuitively recognise with the right hemisphere.
Introduction
Robert Miller in Axonal Conduction Time and Human Cerebral Laterality, 2019
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book explores the manner in which such temporal structure might be represented in the activity of neural tissue. It describes the empirical evidence relating to psychological predictions and deals with a variety of other lateralized functions, at a higher level than immediate perception or programs for immediate motor performance. The book presents a summary of the entire argument, set out as a numbered set of main points. Expressed in terms of basic physical variables language is not a single function, and so it need not be lateralized monolithically to the left hemisphere. All longer strings of spoken language can therefore be analysed as a temporal chain of events, whose essential characteristics cannot be grasped unless temporal resolution at precise temporal structure on the time scale is possible.
The Problem and Clinical Methodology
Aleksandr R. Luria, Lubov S. Tsvetkova in The Neuropsychological Analysis of Problem Solving, 2017
Intellectual activity, which has been thoroughly studied by psychology, has its own peculiar structure and consists of a number of clearly distinguishable phases. The methods used to study conceptual thinking are inappropriate since they establish only the level of abstract codes mastered by the subject which are not indicative of the dynamics of intellectual processes. An injury to the premotor sections of the brain impairs the highest automatisms, hinders the transition from one element of a complex movement to another and impairs the performance of complex motor skills. If the lesion covers the premotor area of the left hemisphere and extends to the area of the second and the third frontal convolutions, it affects verbal processes with the ensuing distortions in the automatization of speech and verbal thinking. The methods of research which are adequate for analyzing so-called nonverbal intellectual operations cannot be applied to study the system of verbal thinking or its dynamics.

Aiming movements are part of daily activities but the brain hemispheres’ role in targeted aiming sequential movements is not fully clear. Start and execution of discrete and sequential tasks toward targets were analyzed in 10 individuals with left-hemisphere damage, 10 right-hemisphere–damaged, and 10 healthy ones. Arm movements were performed over a digitizing tablet, following stimuli on a monitor, from initial position toward right and left-positioned targets. Poststroke individuals used their ipsilesional arm and healthy individuals, both arms. Right-hemisphere–damaged individuals showed higher reaction time and left-hemisphere–damaged individuals, lower smoothness. Due to spatial demand of tasks, the right hemisphere played a major role in movement planning, while the left, in movement execution.
Cerebral processing of proper and common nouns: Perception and production following left hemisphere damage

The goal of this study was to further investigate hemispheric specialization for proper and common nouns by examining the ability of individuals with left hemisphere damage (LHD) to perceive and verbally reproduce famous names and matched common names compared with the performance of matched healthy controls (HC). Ten individuals with LHD due to stroke and 16 age- and education-matched HC completed recognition and production tasks of famous proper and common nouns. All tasks were designed as split-visual field experiments, modelled after the study done by Ohnesorge and Van Lancker. Results contribute to a better understanding of hemispheric roles in perception and production of famous proper nouns, suggesting that (1) both hemispheres can recognize famous proper nouns, possibly due to a right hemisphere role in personal relevance and (2) production of proper nouns as well as common nouns is associated with left hemisphere.
Allometry and Asymmetry in the Dog Brain: The Right Hemisphere is Heavier Regardless of Paw Preference
Published in International Journal of Neuroscience, 1987
The allometric relationship between brain and body size and asymmetry in the weight of the cerebral hemispheres were studied in dogs. A regression analysis of the brain versus body weight revealed an allometric relationship according to the power function Y=kXα. The right cerebral hemisphere was found to be significantly neavier than the left. This finding was not associated with paw preference. In accordance with previous studies, it was concluded that the right-biased asymmetry in the weight of the cerebral hemispheres may be a common feature of the mammalian brain. Functional implications of the results were discussed with regard to the right hemisphere specializations.
