Connections between neurons can be mapped by acquiring and analysing electron microscopic brain images. In recent years, this approach has been applied to chunks of brains to reconstruct local connectivity maps that are highly informative1–6, but nevert

This paper focuses on the problem of human authentication in Body Area Sensor Network using retina. In this proposed method, Voronoi Diagram (VD), a well known technique in computational geometry, is generated from the topological structure of the bifurcation points, considered as vertices, obtained...
A catalogue of neuronal cell types has often been called a ‘parts list’ of the brain1, and regarded as a prerequisite for understanding brain function2,3. In the optic lobe of Drosophila, rules of connectivity between cell types have already proven to
Predictions of Dm3 receptive fields The receptive field of a visual neuron was classically defined as “the region of the retina which must be illuminated in order to obtain a response”28. I predict Dm3 receptive fields by mapping their input connections from Tm1, a cell type that is in ...
Working of the Eye When we look at an object, then light rays coming from the object enter the pupil of the eye and fall on the eye-lens. The eye-lens is a convex lens, so it converges the light rays and produces a real and inverted image of the object on the retina. The retina...

A fundamental question is how the neural coding properties of a circuit relate to its connectivity structure. Recent connectomic efforts have enabled the generation of wiring diagrams in the fly and in vertebrate circuits like the retina1,2, utricular system3,4, olfactory bulb5, visual thalamus6,...
