In an astonishing new study, scientists at the National Institutes of Health (NIH), have imaged human and monkey brains and found… well, the image above says it all. It turns out that the pathways in your brain — the connections between neurons — are almost perfectly grid-like.

It’s rather weird: If you’ve ever seen a computer ribbon cable — a flat, 2D ribbon of wires stuck together, such as an IDE hard drive cable — the brain is basically just a huge collection of these ribbons, traveling parallel or perpendicular to each other. There are almost zero diagonals, nor single neurons that stray from the neuronal highways. The human brain is just one big grid of neurons — a lot like the streets of Manhattan, minus Broadway, and then projected into three dimensions.

A neuron (also known as a nerve cell) is an
electrically excitable cell
that processes and transmits information through
electrical and chemical signals
. Neurons are the core components of the brain and spinal cord of the central nervous system (CNS), and of the ganglia of the peripheral nervous system (PNS). Specialized types of neurons include:
sensory

neurons
which respond to touch, sound, light and all other stimuli;
motor neurons
that receive signals from the brain and spinal cord to cause muscle contractions; and
interneurons
which connect neurons to other neurons within the same region of the brain or spinal cord.
TO-DELT
Close your eyes and imagine walking along a sandy beach and then gazing over the horizon as the Sun rises. How clear is the image that springs to mind?

Most people can readily conjure images inside their head - known as their mind's eye.
But this year scientists have described a condition, aphantasia, in which some people are unable to visualise mental images.
