The human brain’s temporal lobe is the lower lateral lobe structure of each hemisphere. Functions include: general memory, the retrieval of long-term memory, some generation of emotion, and some visual and auditory involvement. Damage to this lobe can cause aphasia.
The human brain’s occipital lobe is the posterior lobe structure for each hemisphere. Functions include: interpretation of vision and some speech.
The human brain’s parietal lobe is a structure at the end of the brain hemispheres below the parietal bone. Functions include: interpretation of sensory input and some control over bodily movement.
The human brain’s frontal lobe is in front, largest, and most anterior structure of the cerebral hemispheres. Functions include: thinking, speech, problem solving, decision-making, some mood involvement, and some motor (movement) involvement. The frontal lobe is the most cognitive part of our brain and doesn’t fully develop until ages 21-22. It is our frontal lobe that allows us to ask deep questions and to deeply think.
The Neocortex encompasses most of the two brain hemispheres14 along with subcortical brain tissue. The 2-hemispheres make up that convoluted outer tissue of many brain folds. The folds somewhat resemble the wrinkles of a walnut and if the folds were rolled out they would be about the size of a large pizza. The Neocortex is our think- ing cap that contain 4 lobe structures.15 Neocortical brain functions depend on brain structure.
Our brain is an exceptional interpretive engine. It attempts to interpret emotional and thinking patterns and associations presented to it so situations and problems can be solved. The Neocortex is a working-brain that has two crucial functions: 1.) analysis = interprets input by cutting information into smaller chunks to make sense out of the parts, and 2.) synthesis = puts chunks and parts together to make sense out of the whole. The brains patterns and associations are mainly deciphered by parts or wholes. However, what I find most fascinating is the working-brains ability to have analysis and synthesis combine, interact, and complement each other and thus allow our brain to have deeper levels of awareness and comprehension. It appears that our brain is usually more proficient at either analysis or synthesis. I have discovered that my working-brain has synthesis as a more pronounced feature. I must work harder to strengthen my analysis brain function and the interaction between synthesis and analysis.
Our Neocortex is the energy-matter that truly distinguishes us from all other creatures in the Animal Kingdom. It is the energy-matter of our new brain, cerebral cortex, and our dianoetic brain. The Neocortex is about 30-40,000 years old and continues to ever so slowly evolve. Brain development starts with childhood sensory input: i. e. to see, hear, smell, taste, and touch. Limbic Brain emotional development starts in early childhood and continues into puberty. Concrete cognitive development happens in mid-childhood and into puberty. It isn’t until the ages of 16-22 that pre-frontal lobe critical cognitive development enters the brains repertoire. It is true that the beginnings of Neocortex structural development starts around three years of age, but this developmental process doesn’t reach full synaptic maturity until the ages of 21-22. The frontal lobe cortical development is only completed in the early 20’s –—> this helps explain why I was still doing some crazy things in my early 20’s. Both synaptic pruning (elimination of excess synapses), and myelination (electrical insulation of axons) continues into ate adolescence and into the early 20’s. Closing of cranial fissures is also completed in the early 20’s. Pruning and myelination increases our ability to learn new things. After the early 20’s the frontal lobe of the Neocortex allows us, if we choose (a big if), to have the ability to critically think and to think about thinking: i. e. meta-cognition.
