Just like a road atlas faithfully maps real-word locations, our brain maps many aspects of our physical world: Sensory inputs from our fingers are mapped next to each other in the somatosensory cortex; the auditory system is organized by sound frequency; and the various tastes are signaled in different parts of the gustatory cortex.

New research may have discovered how memories are encoded in our brains
University of Alberta led research may have discovered how memories are encoded in our brains.
Aging brain gets stuck in time, researchers show
The aging brain loses its ability to recognize when it is time to move on to a new task, explaining why the elderly have difficulty multi-tasking, Yale University researchers report.
New research advances understanding of size perception
Neuroscientists from Western University have taken the all-important first step towards understanding the neural basis of size constancy or the ability to see an object as having the same size despite the fact that its image on the retina changes constantly with viewing distance.
Cracking brain memory code
(Medical Xpress) — Despite a century of research, memory encoding in the brain has remained mysterious. Neuronal synaptic connection strengths are involved, but synaptic components are short-lived while memories last lifetimes. This suggests synaptic information is encoded and hard-wired at a deeper, finer-grained molecular scale.
