Building Atlases of the Brain

BUILDING AtLASES OF THE BRAIN Mike Hawrylycz With Chinh Dang, Christof Koch, and Hongkui Zeng A Very Brief History of Brain Atlases The earliest known significant works on human anatomy were collected by the Greek physician Claudius Galen around 200 BCE. This ancient corpus remained the dominant viewpoint through the Middle Ages until the classic work De humani corporis fabrica (On the Fabric of the Human Body) by Andreas Vesalius of Padua (1514–1564), the first mod- ern anatomist. Even today many of Vesalius’s drawings are astonishing to study and are largely accurate. For nearly two centuries scholars have recognized that the brain is compartmentalized into distinct regions, and this organization is preserved throughout mammals in general. However, comprehending the structural organization and function of the nervous system remains one of the primary challenges in neuro- science. To analyze and record their findings neuroanatomists develop atlases or maps of the brain similar to those cartographers produce. The state of our understanding today of an integrated plan of brain function remains incomplete. Rather than indicating a lack of effort, this observation highlights the profound complexity and interconnec- tivity of all but the simplest neural structures. Laying the foundation of cellular neuroscience, Santiago Ramón y Cajal (1852– 1934) drew and classified many types of neurons and speculated that the brain consists of an interconnected network of distinct neurons, as opposed to a more continuous web. -

The Complications After Keratoplasty
7 The Complications After Keratoplasty Patricia Durán Ospina Fundación Universitaria del Área Andina Seccional Pereira Colombia 1. Introduction Keratoplasty is the medical term that refers to a cornea transplant. There are some differences between the definitions of keratoplasty, commonly it is mentioned for corneal transplant, Lamellar Keratoplasty, which is a partial thickness corneal grafting and penetrating keratoplasty: is a full-thickness corneal grafting. The indications for keratoplasty include: optical (to improve visual acuity by replacing the opaque host tissue by a healthy donor or pesudophakic bullous keratopathy), tectonic (in patients with stromal thinning and descemetoceles, to preserves corneal anatomy ant integrity), therapeutic (removal of inflamed corneal tissue refractive to treatment by antibiotics or antiviral drugs) or cosmetic (in patients with corneal scars giving a whitish opaque hue to the cornea. The most frequent causes of corneal alterations leading to keratoplasty are keratoconus, bacterial infections, poor hygienic contact lens wear (Buehler et al. 1992, Chalupa, 1987, Holden, 2003) or trauma. Among microbial infections, bacterial infections are the most frequent and are mainly caused by Staphylococcus sp., Streptococcus sp. or Pseudomona sp. Some side effects of keratoplasty can be infection (keratitis on the new transplanted cornea or endophthalmitis), transplant rejection, vision fluctuation, glaucoma and bleeding, among others less reported. Infection is one of the most frequent complications after keratoplasty, which can cause endophthalmitis. Infection after keratoplasty, can result from inapropiate healing or like a complication during the transplant (Confino and Brown, 1985 and Dana, 1995). even though the area around the eye is completely sterilized the day of the surgery and the face is covered with sterile drapes. -

Cortical Blindness: Etiology, Diagnosis, and Prognosis
Cortical Blindness: Etiology, Diagnosis, and Prognosis Michael S. Aldrich, MD," Anthony G. Alessi, MD," Roy W. Beck, MD,$ and Sid Gilman, MDI We examined 15 patients with cortical blindness, reviewed the records of 10 others, and compared these 25 patients to those in previous studies of cortical blindness. Although cerebrovascular disease was the most common cause in ow series, surgery, particularly cardiac surgery, and cerebral angiography were also major causes. Only 3 patients denied their blindness, although 4 others were unaware of their visual loss. Electroencephalograms (EEGs) were performed during the period of blindness in 20 patients and all recordings were abnormal, with absent alpha rhythm. Visual evoked potentials recorded during blindness were abnormal in 15 of 19 patients, but did not correlate with the severity of visual loss or with outcome. Bioccipital lucencies were found in computed tomographic (CT) scans of 14 patients; none of the 14 regained good vision. Recovery of vision was poor in all 8 patients who had a spontaneous stroke, but fair or good in 11 of the other 17 patients. Prognosis was best in patients under the age of 40 years, in those without a history of hypertension or diabetes mellitus, and in those without associated cognitive, language, or memory impair- ments. We conclude that (1) the prognosis in cortical blindness is poor when caused by stroke; (2) EEGs are more useful than visual evoked potentials for diagnosis; and (3) bioccipital abnormalities shown on CT scan are associated with a poor prognosis.

Module Specification
MODULE SPECIFICATION KEY FACTS Module name Principles of Therapeutics Module code OVM050 School School of Health Sciences Department or equivalent Division of Optometry and Visual Science UK credits 15 ECTS 7.5 Level 7 MODULE SUMMARY Module outline and aims Information for Clinical Optometry students The Department of Optometry and Visual Science at City University has been providing modular postgraduate training in ocular therapeutics for over 15 years. The purpose of this training has been to provide the theoretical knowledge and clinical skills to enable optometrists to manage ocular disease within the context of the legal and regulatory framework provided by the Opticians Act and relevant medicines legislation. Candidates entering the full independent prescribing (IP) programme will complete a three module scheme (module 1 - Principles of Therapeutics, module 2 - Principles of Prescribing and module 3 - IP) and complete the requisite clinical placement days. Candidates may opt to exit after modules 1 and 2 (following completion of a clinical placement) and qualify as an Additional Supply (AS) optometrist by taking the College of Optometrists’ Common Final Assessment (CFA) in AS. Alternatively, modules can be taken as stand-alone modules as part of the postgraduate programme in Clinical Optometry. Each University module constitutes 15 M level academic credits and will be integrated into our modular postgraduate programme in clinical optometry. An APEL arrangement will be used to import postgraduate credits from the clinical placement aspect of the CFA to allow students qualifying in IP to be awarded a Postgraduate Certificate in Therapeutic Prescribing (PGCTP). Completion of this module (Principles of Therapeutics - module 1 of the AS/IP programme) in addition to modules 2 (Principles of Prescribing) and 3 (IP) will enable optometrists to be entered onto a specialist optometry GOC register for therapeutic prescribing. -
