Neural Circuits and Memory
The neuron is a cell surrounded by electrically charged particles called ions. Some of these ions have a net positive cost and some are negative. If you will find more negative ions inside the neuron, the neuron has a negative electrical charge; conversely, if there are better ions inside, then the neuron has a positive electrical charge. When the neuron is resting it has a negative electrical charge. However , when the neuron will get information, an electrical signal is spread through a network of neurons with a wave of positively charged neurons. Neurons in networks with numerous synapses and feedback loops constantly receive inputs from other neurons, incorporate them and generate electrical activity patterns in response. These complex connections allow neural circuits to procedure and encode information, support intellectual functions and control behavior. The neural circuits in our brain are similar to electrical circuits.
Canadian psychologist, Donald Hebb, explains memory as a reactivation of the same pattern of neurons that were activated at the time of the original encounter. Thinking of the Sahara desert activates one network of neurons, whilst thinking of rats fires up a completely different network. Over the years, some of the neurons die or are incorporated into circuits that represent different encounters. Repeated activity between any two neurons or a network of neurons, however , strengthen their connections as well as the memories they represent. When 1 neuron is activated it tends to activate the others, which collectively re-create the original pattern that was generated throughout an experience.

Individual neurons are involved in a variety of circuits and thus participate in many memories simultaneously. It is this connectivity that gives our brains the enormous capability to encode a vast amount of information.
Holographic Encoding in the Brain and Universe
Following Karl Lashley’s work, Karl Pribram, a neurophysiologist in Stanford, proposed that the brain shops information in the same way as interference patterns are encoded on holographic film. Every element in the original image is usually distributed over the entire film. Trillions of brain cells all help with a single memory by recording and combining all the signal patterns at once, including the sensory inputs into the human brain. It is the combined firing pattern and interference of trillions of tissue that defines a memory. This excellent way of storage allows the brain to recall in linear sequences and at the same time access multiple memories.
However it is not only the brain which encodes holographically. David Bohm, separately, recognized the universe itself appears to be a hologram – being projected from the border of the universe. This idea continues to be taken forward more recently by physicists Gerard t’ Hooft, Lee Smolin and others under the banner of “the holographic principle”. This is not the only house that the human brain shares with the world.
Neural Networking in the Cosmic Brain
According to the European Southern Observatory (ESO), “All recent computer-simulations of the early universe have one prediction in common: the very first large-scale structures to form in the youthful universe are long filaments linked at their ends in ‘nodes’. The particular models typically look like a three-dimensional spider’s web, and resemble the neural structure of a brain. ” At this point, astronomers have actually detected a “universal web” – vast filaments of hot gas tracing the internet have been “seen” in the current universe. Astronomers using NASA’s X-ray satellite observatory, Chandra, “viewed” the filaments stretching for millions of light years through space, with one passing through our own galaxy. Astronomers say that the particular filamentary structures are so hot that it would generally be invisible to optical, infrared, and radio telescopes. These invisible filaments are detected only because higher density normal matter tends to accumulate and reduce in them – generating radiation which may be measured by scientists to confirm their own existence in intergalactic space.
The particular visible galaxies in the universe aren’t isolated and disconnected but are usually interwoven by a filamentary web-like construction – which is the invisible dark matter scaffolding of the universe. The web-like structure is both the signature feature of invisible dark matter and magnetic plasma. The appearance of this web bears an uncanny resemblance to a cross-section of the mind. (Refer: Brain vs Universe)
But it is not only the morphology (i. electronic. structural aspects) of the large scale structure of the universe which is just like the human brain but also the physiology (i. e. the functions). These filaments carry currents of charged contaminants (ions) over large distances that generate magnetic fields – comparable to a nerve fiber. And they form circuits, just like the neural circuits within the brain.
