The frontal lobes
The largest lobe is the one that is coloured in blue. It covers the front two thirds of the surface and it is called the frontal lobe. This is the one that is most commonly injured because the eyes are right in front of it.
Connection between the occipital lobe and vision
As shown here the occipital lobe is the part of the brain connected to the eyes because it allows you to see. The eyes are more like holes that let light in. The occipital lobe processes the image and lets you know what you saw.
What happens if your occipital lobe to eye pathway malfunctions
If it didn’t work, you could still see, technically, but you would not know what you saw. You define the would not know what it means, which is mostly what you are doing when you are reading.
Occipital lobe transitions to
The parietal lobe
But while sight is the main sense controlled here, almost all the other senses are controlled by the area right in front of the occipital lobe, termed the parietal lobe.
The parietal lobe transitions to
The frontal and temporal
Concluding sentence on overview
The area covered by it and the rest of the lobes are shown here but they’re also shown on the other slides do don’t worry about remembering them all.
Intro the lobes
In the brain, different areas control different things that you do. These areas are grouped into four major sections called lobes. On the left is what you would see if you looked at the brain from the front, but you would only see all these lobes if you looked at it from the bottom right.
Parietal transition to frontal
But most of the information is sent to the frontal lobe.
Parietal to occipital connection
The signals sent back to the occipital lobe combine vision with proprioception to create spatial navigation, which allows you to get to places because it tells you where they are.
Sensory areas found in parietal lobe
Here you can find many other sensory areas, like those for Taste, hearing, touch, smell and even temperature, pressure, vibrations, pain and proprioception, which is how you know where things are even if you dont see them.
Specific things the frontal lobe does
It is the seat of our personality and voluntary behaviour. It also controls your judgement, movements, self-control, memory, attention span, and inhibitions, which tell you what NOT to do. It allows you to learn new things, make decisions, and use logic
Intro the frontal
It receives a lot of information because it is responsible for the most difficult tasks, the ones that require the most energy and skill.
Cross reference the frontal
That is why it is the only thing visible in the angled view shown on the top left. It had grown more than any other lobe.
Specific things the parietal lobe does
The signals sent here include anything about most senses, especially your sense of sound or smell. Certain parts of it store your memories, allow you to produce language, process your emotions and even aid in your sense of sight.
