Barrow scientists make headlines for their research on fixational eye movements
July 25, 2007Susana Martinez-Conde, Ph.D., director of the Laboratory of Visual Neuroscience, and Stephen Macknik, Ph.D., director of the Laboratory of Behavioral Neurophysiology at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center, are featured on the cover of the August issue of Scientific American for their research on fixational eye movements. The pair was also featured in a recent issue of the Wall Street Journal.
"Scientific American is considered by many to be the Rolling Stone magazine of science," says Dr. Macknik. "It is a honor in our career to be featured in such a prestigious publication."
Drs. Martinez-Conde and Macknik authored an article describing the history of fixational eye movement research and the investigations they have conducted at Barrow. For decades, researchers have debated the purpose of fixational eye movements and particularly of microsaccades, the largest and fastest of fixational eye movements. Recent research conducted by Dr. Martinez-Conde and her team at Barrow has shown that microsaccades produce visibility when a person's gaze is fixed on an object. Microsaccades may also help reveal a person's subliminal thoughts. Fixational eye movements are responsible for driving most of our visual experience and without them humans would become blind to stationary objects.
"We are thrilled to have our research highlighted in Scientific American," says Dr. Martinez-Conde. "Fixational eye movements have long been debated and our research has proven that they do serve a very important purpose."

Researchers at the Center for Molecular and Behavioral Neuroscience (CMBN) at Rutgers University in Newark have identified the need to develop a new framework for understanding "perceptual stability" and how we see the world with their discovery that visual input obtained during eye movements is being processed by the brain but blocked from awareness.
LSUHSC research shows fish oil protects against diseases like Parkinson's
Dr. Nicolas Bazan, Director of the Neuroscience Center of Excellence, Boyd Professor, and Ernest C. and Yvette C. Villere Chair of Retinal Degenerative Diseases Research at LSU Health Sciences Center New Orleans, will present new research findings showing that an omega three fatty acid in the diet protects brain cells by preventing the misfolding of a protein resulting from a gene mutation in neurodegenerative diseases like Parkinson's and Huntington's.

The Neurology of Eye Movements: Book-and-DVD Package (Contemporary Neurology Series, 70) by R. John Leigh M.D. (Author), David S. Zee M.D. (Author) This new edition of Neurology of Eye Movements is a major revision providing clinicians with a synthesis of current and new scientific information that can be applied to the diagnosis and treatment of disorders of ocular motility. Basic scientists will also benefit from descriptions of how data from anatomic, electrophysiologic, pharmacologic, and imaging studies can be directly applied to the study of disease. By critically reviewing such basic studies, Drs. Leigh and Zee build a conceptual framework that can be applied to the interpretation of abnormal ocular motor behavior at the bedside. These syntheses are summarized in boxes, figures, schematics, and tables. Insights and techniques from current research, case examples, bedside and laboratory studies, and thousands of references are... |
