The Hands to Say It
Issue 91, February 2008 www.proteinspotlight.org The hands to say it Vivienne Baillie Gerritsen When I was a little girl, I thought that my left-handed classmates were special. I envied their difference. And I used to marvel at the way they crouched over their desk, embracing something invisible as they did their best to avoid smudging ink all over their sheet of paper. Left-handedness is special. But so is right-handedness. Humans are not the only animals to make use of their hands – or claws, or paws, or hooves - but they are the only ones who show a marked preference for either the left one, or the right one. If this is so, there must be a reason for it. And not only must there be a reason but it must translate a certain structure of our brain: an asymmetry somewhere. Indeed, our brain is divided into two hemispheres which are dedicated to processing different activities. One side looks after our dreams, while the other is far more down to earth. LRRTM1 is the first protein to have been discovered which seems to be directly involved in this brain asymmetry. Consequently, it influences the handedness of a human-being and, more astonishingly, may also predispose individuals to psychotic troubles such as schizophrenia. don’t have a distinct preference for one hand over the other. The passing of roles from hand to mind expresses a particular brain structure. In turn, the progressive use of speech has continued to mould our brain into a shape peculiar to the human species. -

Symmetry and Beauty in the Living World I Thank the Governing Body and the Director of the G.B
SYMMETRY AND BEAUTY IN THE LIVING WORLD I thank the Governing Body and the Director of the G.B. Pant Institute of Himalayan Environment & Development for providing me this opportunity to deliver the 17th Govind Ballabh Pant Memorial Lecture. Pt. Pant, as I have understood, was amongst those who contributed in multiple ways to shape and nurture the nation in general and the Himalayan area in particular. Established to honour this great ‘Son of the Mountains’, the Institute carries enormous responsibilities and expectations from millions of people across the region and outside. Undoubtedly the multidisciplinary skills and interdisciplinary approach of the Institute and the zeal of its members to work in remote areas and harsh Himalayan conditions will succeed in achieving the long term vision of Pt. Pant for the overall development of the region. My talk ‘Symmetry and Beauty in the Living World’ attempts to discuss aspects of symmetry and beauty in nature and their evolutionary explanations. I shall explain how these elements have helped developmental and evolutionary biologists to frame and answer research questions. INTRODUCTION Symmetry is an objective feature of the living world and also of some non-living entities. It forms an essential element of the laws of nature; it is often sought by human beings when they create artefacts. Beauty has to do with a subjective assessment of the extent to which something or someone has a pleasing appearance. It is something that people aspire to, whether in ideas, creations or people. Evolutionary biology tells us that it is useful to look for an evolutionary explanation of anything to do with life. -

Crow Schizophrenic illnesses occur with approximately the same incidence in all human populations with a characteristic distribution (slightly earlier in males) of ages of onset.Given that the predisposition (which presumably is genetic) is associated with a procreative disadvantage why do such illnesses persist? Here it is suggested that these conditions are a manifestation of genetic diversity in the evolution of the specifically human characteristic of language, an innovation that has occurred by a process of progressive hemispheric specialization – the establishment of dominance for some critical component of language in one or the other hemisphere. -

A Cinch for the Brain
A Cinch for the Brain Our bodies, our behavior and even our brains are anything but symmetrical. And this seems to be an important factor in the seamless functioning of our thought, speech and motor faculties. Researchers at the Max Planck Institute for Psycholinguistics in Nijmegen are currently searching for genetic clues to this phenomenon. They want to decode the fundamental molecular biological mechanisms that contribute to asymmetry in the brain, and to identify possible causes for neurological disorders.

Manual Asymmetry and Handedness (Trophi Nteclon/Smt Symme-A Try) DALE PURVES*, LEONARD E
Proc. Natd. Acad. Sci. USA Vol. 91, pp. 5030-5032, May 1994 Neurobiology Manual asymmetry and handedness (trophI nteclon/smt symme-a try) DALE PURVES*, LEONARD E. WHITE, AND TIMOTHY J. ANDREWS Duke University Medical Center, Department of Neurobiology, Durham, NC 27710 Contributed by Dale Purves, February 2, 1994 ABSTRACT Volumtric mnasurements show that right- handed Individuals have lager right hands than left hands. In contrst, the hands of left-handers are much more nearly symmetrical. Based on what Is known about tophic interac- dons between neurons and targets, these fings predict a c d aSymmetr of the relevant parts of the sensori- motor system in right-handers. The lack of an opposite-hand asymmy among left-handers further implies that right- and left-handed phenotypes do not arise according to the same developmental rules. Nerve cells and their targets are linked by long-term trophic interactions that coordinate somatic and neural growth (see ref. 1 and below). If one hand is generally larger than the other-as some earlier studies of the human metacarpals suggest (2, 3)-then this asymmetry should be reflected in the size of the related neural structures. As a first step in exploring this neurosomatic relationship, we have measured the volume of the two hands among right- and left-handers. We solicited 52 adult volunteers (students, faculty, and staff from Duke University) who described themselves as right-handers and 50 who considered themselves left-handers (Table 1). The volumes of the two hands were measured for FIG. 1. Diagram ofapparatus used to measure hand size by water each subject by a simple water displacement technique (Fig. -

Right Vs. Left
High Touch High Tech® Science Experiences That Come To You Right vs. Left Ingredients & Supplies: • pencil • paper • scissors • ball, small (ex. tennis ball, baseball) • ball, large (ex. soccer ball) • coin • paper towel tube • phone • stairs • cup of water Instructions: If you use your right hand to write and draw, you are right-handed. If you use your left, you are left-handed. This is your dominant hand. Most people are right-handed. In fact, only 10% of the population uses their left hand to write. Scientists are unsure why most people favor one hand. Perhaps it is genetic, health-related, or environmental. The left- hand minority remains a mystery. But, this isn’t the only way to determine your “sidedness.” You also have a dominant ear, eye, and foot. Usually if someone is right-hand dominant, he favors the right side of his body. But, this is not true for everyone. Sometimes, a person may write with his right hand, but throw a baseball with his left hand. This is called “mixed-handedness” or cross- dominance. If a soccer player favors her right foot, but draws with her right hand, this is also cross-dominance. When someone can use both sides of the body equally well, he or she is ambidextrous. This is a rare form of cross-dominance (about 1% of the population) because the person can write, throw, and kick with either the right or left side with skill. Now you can experiment to find out which side is dominant for you, your friends, and your family! Everyone knows immediately if they are right-handed or left-handed. -

Box 1346 Ann Arbor, Ml 48106- 1346 ii PREFACE Lack of knowledge concerning left-handedness springs from the multiplicity of studies and contradictory nature of the findings on the various aspects of laterality, father than any insufficiency of material on the subject. The absence of any single authoritative work and extensiveness of existing material make necessary for a full appreciation of the problem a study more prolonged than the average interested person is willing or able to make. The present work, presenting as it does both an attempt at critical evaluation of previous investigations and an original study of laterality characteristics in a group of normal children, will it is hoped satisfy a need for a comprehensive report on the subject. The practical problems confronting teachers and parents dealing with left-handed children have been kept in the forefront through out, in the hope that the information contained herein may make some contribution towards a better understanding of left-handedness and may even lead to a more tolerant attitude towards the * sinister minority*, to which the author herself belongs.
