How many hearts does a squid have? Where are the ventricles located in the heart? How many platelets are in the human body? How many neurons are in the human body? How many nerves are in the human body? How many systems are there in human body?
So if you put something in your brain that replaces a brain function, your brain deletes that aspect of its biology, the synapses collapse, the neurons disappear. So, if you’re in the transhumanist movement, you’re actually going to have a smaller brain. 'If you're in the transhu...
You often hear people comparing the human brain and the electronic computer and, on the face of it, they do have things in common.A typical brain contains something like 100 billion minuscule cells called neurons (no-one knows exactly how many there are and estimates go from about 50 ...
"We can measure the activity of individual brain cells in the hippocampus while the patient performs a task," says Matthew Self. "In the hippocampus, there are cells that respond to a specific person, so-called 'concept cells.' A well-known example is the 'Jennifer Aniston cell,' which b...
Olfactory receptor cells are neurons with knob-shaped tips called dendrites. Olfactory hairs that bind with odorants cover the dendrites. When an odorant stimulates a receptor cell, the cell sends an electrical impulse to the olfactory bulb through the axon at its base. Supporting cells provide st...
In the last decade a revolution has occurred in the way that scientists think about the brain. We now know that the decisions humans make can be traced to the firing patterns of neurons in specific parts of the brain. These discoveries have led to the field known asneuroeconomics, which stu...
There are no reliable statistics on how many people have CIPA at this time, but the condition is quite rare. It does not seem to affect one gender more than another. So how does not feeling pain work? First, let's learn a little bit more about the nervous system. Your nervous system...
The current world gradually looks and feels worse, as does the past. The hippocampus is worn down, and memories harder to retain. Cortisol further suppresses new neurons in the hippocampus. Too much SNS-HPAA has negative impacts on the gastrointestinal system (more ulcers, inflammatory bowel ...
We're learning more about the craving that fuels self-defeating habits—and how new discoveries can help us kick the habit.
This strong surge in blood glucose levels caused by the OGTT may therefore result in an inhibition of the wake-promoting neurons in the hypothalamus30, and this loss of hypothalamic drive may ultimately lead to reduced alertness. The third non-mutually exclusive explanation for why the pure ...
