Görme: Sistemsel Sinirbilimi Bakış Açısı
H Kafalıgönül
Bilkent Üniversitesi, Ankara
Görsel sistem korteksin en çok incelenen parçasıdır.Bu durum görsel sistemin sadece görmenin temelindeki sinirsel işlemler hakkında değil beynin genel çalışma prensiblerini anlamaya dayalı bir temel teşkil etmesinden kaynaklanmaktadır. Şu ana kadar farklı görsel özelliklere (örneğin şekil, yüzey aydınlığı, renk, hareket) duyarlı sinirsel yapıları anlamaya yönelik çok önemli ilerleme kaydedilmiştir. Bu makalede, görsel özelliklere duyarlı temel sinirsel yapılar and işlevsel yollar gözden geçirilmiştir. Herhangi bir işlevsel yoldaki fonksiyonel bozukluk farklı görsel özelliklerin algısında eksikliklere yol açmaktadır. Son yıllarda, görsel bilimdeki bilgi birikimini nörolojik bozukluklarda rastlanan sinirsel yapı değişikliği ve buna dayalı anormal algısal işlemleri anlamada kullanmaya yönelik artan bir ilgi bulunmaktadır. Bu yönde gerçekleştirilmiş kilit konular ve klinik çalışmalar da görsel özellik işlemesi bağlamında tartışılmaktadır.
Vision: A Systems Neuroscience Perspective 
The visual system is the most studied part of the cortex, providing a basis for understanding not only visual processing per se but also the fundamental operations of the brain in general. Significant progress has been made in understanding neural structures sensitive to different visual attributes such as form, surface brightness, color and motion. Here, the basic neural structures and processing pathways for these visual features are reviewed. Dysfunctions in these processing pathways lead to deficits in the perception of different aspects of a visual object. In recent years, there is a growing interest in applying accumulated knowledge in vision science to investigate altered neural structures and abnormal perceptual processing observed in neurological disorders. Key issues and clinical studies are also discussed within the context of visual feature processing.
