BACKGROUND Anatomical Aspects
Physiological AspectsANATOMICAL ASPECTSPre natal period
Just before birth
Post natal periodFACTORS AFFECTING Genetic & Molecular control
Onset of electrical activity
Receptive fields
Chemical mediators & Neuromodulatory transmittersGenetic & Molecular controlNormal structure development
Peripheral retinal development
Contour integrationELECTRICAL ACTIVITY Purpose
 LTP & LTD
Cells that fire together wire together
Two distinct pathwaysRECEPTIVE FIELDSFurther refinement under influence of visual experience
Group of cells behave in a similar manner
On – center & Off – center cells
Receptive fields in cortexChemical mediators & Neuromodulatory TransmittersControls circular receptive fields of retinal cells
 Influence the visual cortex via modulatory pathways from other sites within cerebral cortex
 Critical period, Plastic period & Amblyopia Correlation with visual function development Visual Acuity
Contrast Sensitivity
Orientation Specificity & Motion Selectivity
