Now that the final book in The Cybernetic Theory of Mind series is released, the entire eBook series is available on Amazon all in one place!
This is a 5-book set on the ultimate nature of reality, consciousness, physics of time, computational physics, philosophy of mind, foundations of quantum physics, technological singularity, transhumanism, impending phase transition of humanity, simulation hypothesis, economic theory, extended Gaia theory, transcendental metaphysics and God, all of which is combined into one elegant Theory of Everything.
If you’re eager to familiarize with probably the most advanced ontological framework to date or if you’re already familiar with the Syntellect Hypothesis which, with this series, is now presented to you as the full-fledged Cybernetic Theory of Mind, then this series will surely present to you some newly-introduced and updated material if compared with the originally published version and can be read as a stand-alone work just like any book of the series: https://www.amazon.com/dp/B08R2K7ZK2?tag=lifeboatfound-20

Human Neurons Found to be Surprisingly Different From Other Mammals
Ion channels are crucial for neural communication; they control the flow and gradient of charged particles, creating electrical signals. Recent work report | Neuroscience.
In this study, the researchers assessed how dense ion channels were packed in the membranes of neuronal cells from ten species of mammals, including mice, rats, rabbits, ferrets, macaques, marmosets, macaques, humans, and one of the smallest known mammals, an animal called the Etruscan shrew. The team focused on a type of excitatory neuron typically found in the cortex of the brain, and three ion channels that are in the membranes of those cells; two are voltage-gated ion channels that control the movement of potassium, another is called the HCN channel and both potassium and sodium ions can flow through it.
Studies have suggested that the human brain is built like the brains of other mammals, said first study author Lou Beaulieu-Laroche, a former MIT graduate student. It was once thought that in mammals, these channels would be present at about the same density from one species to another.
Instead, the researchers determined that as the neurons got bigger, the density of ion channels increased. That was a notable finding, because as that density increases, more energy needed to move ions in and out of neurons, explained senior study author Mark Harnett, an associate professor of brain and cognitive sciences at MIT.
How Grief Rewires The Brain
Grief can be overwhelming. Here’s what’s going on in the brain when you’re heartsick.

But having strong relationships also means the possibility of experiencing loss. Grief is one of the hardest things people go through in life. Those who have lost a loved one know the feeling of overwhelming sadness and heartache that seems to well up from the very depths of the body.
Dendrites may help neurons perform complicated calculations
Within the human brain, neurons perform complex calculations on information they receive. Researchers at MIT have now demonstrated how dendrites—branch-like extensions that protrude from neurons—help to perform those computations.
The researchers found that within a single neuron, different types of dendrites receive input from distinct parts of the brain, and process it in different ways. These differences may help neurons to integrate a variety of inputs and generate an appropriate response, the researchers say.
In the neurons that the researchers examined in this study, it appears that this dendritic processing helps cells to take in visual information and combine it with motor feedback, in a circuit that is involved in navigation and planning movement.
Temperature and reproduction link holds promise for insect control
Scientists have uncovered a set of neurons in fruit flies that shut down in cold temperatures and slow reproduction, a system conserved in many insects, including mosquitoes, which could provide a target for pest control.
Their study, published Feb. 16 in the journal Current Biology, takes a step toward understanding how a fly’s brain contributes to sensing the cold and limiting reproduction. Insects and animals, including many mammals, curb reproduction in the winter to protect their newborns from being exposed to harsh winter conditions.
The study has public health and agricultural implications, as tapping into environmentally-dependent mechanisms that influence reproduction in mosquitoes and crop pests may offer new control strategies. Mosquitoes act as reservoirs for the malaria-causing Plasmodium falciparum parasite, which spend the winter inside them.
