My Name is Tom and I am the survivor of an ABI.
In the last post, I covered the injuries to the brain that I suffered (as I understand them in layman’s terms). In this post, I will be looking at the different sections of the brain, what they do (again, as I understand it), and that will lead us on to the next few weeks where I will discuss the problems I had when waking from my induced coma. Trust me, I am doing my best to get away from the medical stuff, the neurology, and move quickly on to my experiences and the real meat of this blog.
From the research I did through my medical notes, it seems that most of the damage was done to the temporal lobe, the occipital lobe, and some minor damage to the frontal lobes (and I’m sure other places suffered some minor damage due to the midline shift/increased ICP). Now, finding out the function of the different parts (or lobes) of the brain has been interesting to me as it has allowed me to put the after effects I still suffer from in some kind of context. I had done little to no research prior to this blog on what effect the damage to different parts of my brain has had on me. It is much easier to not address it: to live in denial of something is a lot easier than accepting it and taking steps to address and overcome it. After all, it is only really in the last year to eighteen months where I have started to truly accept my ABI and what it has done to me.
Now, the different lobes of the brain and what they do. This is how I understand it and the picture below should give some clarity on the locations of the different lobes.
The main section of the brain is called the cerebrum and provides the tools for thinking that we use in every day life. It is divided into right and left hemispheres: The left hemisphere is responsible for the logical side of thinking, numbers, words, lists, logic, sequence, linearity etc. and controls the right side of your body. Whereas the right hemisphere controls the left side of your body and is responsible for the more creative endeavors such as rhythm, spatial awareness, colour, imagination and daydreaming. The cerebrum is then split into four different lobes, each of which has a different function.
- The Frontal Lobe – The frontal lobe controls so many different aspects of what we do and what our brain does. To include just a few, it controls creative thought, problem solving, intellect, judgement, behaviour, attention, physical reactions, muscle movements, smell and personality.
- The Parietal Lobe – The Parietal Lobe mainly focuses on comprehension, monitoring things such as language, reading, visual functions, internal stimuli and sensory comprehension. It is also home to the Sensory Cortex and the Motor Cortex. The Sensory Cortex receives information from the spinal cord regarding the position of our many body parts and how we are moving those body parts. The Motor Cortex helps to check and control the movement of the body.
- The Temporal Lobe – The Temporal Lobe controls our visual and audio memories. Located here are sections that help us with speech and language as well as hearing. It also has an effect on some of our behavioural factors. The Temporal Lobe also houses Wernicke’s Area. Little is known about this area by even the best doctors but it is known to help us formulate/understand speech.
- The Occipital Lobe – located at the back of the head, it helps to control vision. The Occipital Lobe also houses Broca’s Area, the area of the brain that controls the facial neurons as well as our understanding of speech and language.
So theses are the four main lobes of the brain. I promise you, that that should be that on the science jargon. But I felt it to be important to include some of the scientific/neurology stuff as it places my future experiences in a proper context. So I hope to see you here again. Would love it if I could get a few more followers on Twitter (follow me @ABIblogger) and maybe follow my blog while you’re here. I assure you I am doing this with the main aim of helping people. Any feedback I can get would be amazing! Thank you so much everyone. Stay strong!
