However, damage to neurons can have great impact. A piece of brain tissue the size of a grain of sand contains 100,000 neurons and 1 billion synapses.The cold creates a dilation and contraction of arteries, causing a rapid-onset headache. This pain occurs when cold hits the receptors in the outer covering of the brain, called the meninges. A brain freeze is really a sphenopalatine ganglioneuralgia.Men tend to have larger brains than women. (That’s about as much as a half-gallon of milk.) However, size does not always imply intelligence. (Yes, even when you are sleeping.) Neurologists confirm that your brain is always active. It’s a myth that you only use 10 percent of your brain.
In MS, the immune system attacks the protective layer that covers nerve fibers, causing communication problems between the brain and the body. Another disease that affects both the brain and the spinal cord is multiple sclerosis (MS). ALS, or amyotrophic lateral sclerosis, causes the neurons in the brain and spinal cord to die, impacting controlled muscle movement. The spinal cord is the main source of communication between the body and the brain.Your spinal cord, which consists of a bundle of nervous tissue and support cells, is responsible for sending messages from your brain throughout your body. On average, your spinal cord stops growing at 4 years old.A disruption in this regular processing can cause an epileptic seizure. When a neuron is stimulated, it generates an electrical impulse that travels from cell to cell. Brain information travels up to an impressive 268 miles per hour.However, in Alzheimer’s disease, for example, many neurons can become damaged and stop working, particularly affecting memory. Over time, these neurons can combine, increasing storage capacity. Each neuron forms connections to other neurons, which could add up to 1 quadrillion (1,000 trillion) connections. Research suggests the human brain consists of about 86 billion neurons. Your brain’s storage capacity is considered virtually unlimited.
Therefore, your frontal lobes, which control planning and reasoning, are the last to strengthen and structure connections. Brain development begins from the back of the brain and works its way to the front.
