The human brain is the command center of the neurological system, receiving input and sending output. It contains around 100 billion neurons that can form up to 10 trillion connections, allowing memories and information to be stored in complex networks. While fully developed by age 11, some higher functions continue developing into the mid-20s. The brain's exact memory storage is difficult to calculate due to variable memory sizes and loss of unused information over time.

2. The human brain is the command center
for the human neurological system. It
receives input from the neurological body
parts and sends output to the muscle
tissues. Memories and information are
stored in the brain via a network of cells
called neurons.

3. :
 The human brain structure is almost fully
developed by age 11, though some higher self-
management brain functions continue to develop
into the mid 20’s.
 The diameter of an individual brain neuron is 4
microns, meaning 30,000 could fit on the head of
a pin.
 The human brain has 100 billion neurons, making
it the most powerful learning tool in the world.
 Each single brain neuron has from 1,000 to
10,000 connections with other neurons, making
up to 10 trillion neuron connections possible.
 The same part of the brain interprets both your
physical and emotional pain.

4. The brain’s exact storage capacity for memories is
difficult to calculate. First, we do not know how to
measure the size of a memory. Second, certain
memories involve more details and thus take up more
space; other memories are forgotten and thus free up
space. Additionally, some information is just not worth
remembering in the first place.

5. The memory storage capacity of the human brain is so large
because information is most likely stored in connections between
the cells.
