BRAIN FUNCTIONING
How does the brain work?
What are the main parts of the brain and what is the connection with the rest of the body?
Does exercise affect Brain functioning?
How important is movement in improving brain functioning?
This and other questions will be answered in this newsletter
I will walk you through this exciting journey. First let’s give a few brain facts:
%Brain of total body weight (150lbs human)= 2%
The brain weighs approx 3 lbs.
We have around 100 bn neurons
Out of the 100 bn neurons, 50 bn of them are located in the Cerebellum (see picture above).
Number of synapses per neuron: (1,000 to 10,000)
“Exercise might strengthen pre synaptic connections”

DIFFERENT PARTS OF THE BRAIN:
The Cerebellum:
The cerebellum is the brain’s headquarters for balance, coordination and cognitive learning, among other functions. However, the cerebellum accounts for just 10% of total brain mass.
Therefore, this part of the brain is crucial to children’s attention span, and also to adult, especially people interested in retarding the aging process.
According to professor Anthony Goodman (Montana State University) he explains, “The cerebellum function as the part of the brain the coordinates input from sensory organs of proprioception (eyes and ears unquote) and ensures that intention and actual movement are the same. It makes possible coordinated complex motor function such as dancing or playing the piano”.
There are four different lobes: |
| |
| The Frontal Lobe: |
It is responsible for reasoning, emotions, reasoning, speech and voluntary movement. Teenagers and adults have a significance difference in the frontal lobe development. It is necessary to activate other parts of the brain to improve decision-making. |
| Temporal Lobe: |
Here is where different processes occur such as: auditory, memory or speech. |
| Parietal Lobe: |
Activities such as movement, orientation and face recognition. |
| Occipital Lobe: |
Visual processing, analyzing |
| Limbic System: |
| Here is where most activity regarding stress, fear, memory, and learning occurs. The different parts of the Limbic System are: |
| Hypothalamus: |
is responsible of homeostasis (brings the brain to its original state) |
| Hippocampus: |
is responsible for learning and memory. Here is where most of the memories storage happens. |
| Amygdala: |
: Is responsible for fear and sexual responses |
|
|
|
| |
Brain Stem: it regulates the breathing, heartbeat or blood pressure.

The intention if this section it was to give you an outlook of the different brain’s parts. There are parts that have not been mentioned such as medulla oblongata, spinal cord and many more. We will keep updating with new articles explaining this fascinating process.
