The human brain can be divided into six (6) distinct areas; each with its' own
primary functions. Generally, most limit it to four (4) or five (5), neglecting the 'brain stem' &
'cerebellum', though these are vital to those functions that are 'essential to basic life', not
merely higher cognitive functioning.
Damage to any
of these areas can have the resultant effect of disturbances to their primary functions. This damage &
consequential 'malfunction' can take the form of 'physical' changes'; 'structural
changes'; 'atrophy'; 'neurotransmitter deficiencies',
'anomolies', 'imbalances' and so on.
Below is a brief outline as to these specific 'lobes' & the
associated areas of influence & 'responsibility'.
There are two (2) lobes (left & right)
Primarily responsible for 'sensations' or the 'senses' &
described as the 'Primary Sensory Cortex'
Touch, pressure, taste, temperature
Control of 'fine sensations' & the capacity for.....
Judgment of weight, size, texture, shape etc.
Also responsible for language functions
As with the 'Parietal Lobe', there are two (2) Temporal Lobes
(left & right)
Involved in 'visual memory' (right side)
Sense & capacity for differentiation in smells
Involved in 'short term memory'
Verbal memory &/or comprehension of vocabulary, words, phrases,
names etc. (left side)
Involved in the processing of visual information receiving information
& signals (via electrical neurotransmission) via the eyes & optic nerve
Also integral in the visual recognition of shapes, colours &
Responsible for the concept & co-ordination of balance
Movement - both fine motor & gross motor
Muscle movement & posture
Also believed to be linked to thinking & emotions
The lower part of the brain, where it connects to the 'spinal
Its' functions are vital for basic human survival
In the earliest stages of embryonic & foetal development, this part
of the brain is that which develops initially
Controls or regulates breathing or respirations
Heart rate regulation
Level of alertness or wakefulness
The 'Brainstem' is the conduit or pathway for all perpheral
nerves & spinal cord/nerves, both ascending & descending (transmitting & receiving), and
connecting to the higher parts of the brain itself itself; the cerbral cortex.
The Brain is made up of 78% water, 10% fat & 8% protein. It
contains billions of neurons held together by cells called 'Glial Cells'. Given that neurons consitute
approximately 10% of brain cells and Glial Cells the remainder, this equates to about 1,000 billion in our
The 'Glial Cells' not only hold & support the growing
brain and its neurons, but also provide the necessary nutrients, chemicals (food) etc. required by the neuronal
cells. There is evidence to suggest that the greater number of Glial Cells in a particular area, the greater the
ability for the functions of that area to be maximised. Albert Einstein's brain, when examined by scientists,
showed a huge number of Glial Cells in a specific region of the brain; significantly more than seen in
Other essential areas of regions of the brain are as
controls body temperature, emotions, thirst, appetite, hunger, sleep & digestion
The Hypothalamus, Amyglada & Hippocampus
comprise a structure known as the 'Limbic System', being linked by massess of densely packed neurons &
