Sensory maps and brain development the midbrain auditory nucleus had receptive fields independent of nature and intensity of the sound. Roger Sperry proposed a chemical gradient model for eye rotation and for neuronal wiring diagram. Retinal neurons and target cells had identification tags in the form of chemical gradients so that the projection of neurons would be orderly. For a topographic map of the visual world, the map first forms during neural development via molecular signals, such as chemospecific matching between molecular gradients. The molecular basis of sensory maps and brain development is a field that is being actively explored. The most recent work has
Brain Electrical Oscillation Signature Profiling information associated with a prior experience. Brain Electrical Oscillation Signature Profiling Brain Electrical Oscillation Signature Profiling (BEOSP or BEOS) is a technique by which a suspect's participation in a crime is detected by eliciting electrophysiological impulses. It is a non-invasive, scientific technique with a great degree of sensitivity and a neuro-psychological method of interrogation which is sometimes also referred to as ‘brain fingerprinting’. The methodology was developed by Champadi Raman Mukundan (C. R. Mukundan), a Neuroscientist, former Professor & Head of Clinical Psychology at the National Institute of Mental Health and Neurosciences (Bangalore, India), while he worked as a Research
