Logical Symbolic Thinking

How is logical symbolic thought and language encoded in the brain? A possibility is that the language centers in the STS (superior temporal sulcus), parietal association cortex, and dorsolateral prefrontal cortex communicate with one another during logical brain operations involving symbolic thought. The superior tempral sulcus, both anterior and posterior, plays some roles in social cognition and self concept. It also helps process speech and reading signals. It clearly plays a role in human language. The inferior frontal gyrus or Broca’s area has a use in motor plans of speech. The Wernicke area in the anterior inferior gyrus of the parietal lobe is involved in sensory reception of speech, ie. Speech processing. The latter is related
This schematic is one, two, and three step logical thinking. The Premises can be anything such as steps in a logical sequence scheme or those in a three step mathematical problem. Roger Carpenter sets this up as a summary of Wittgenstein’s thinking in the final chapter of his book Neurophysiology 4th edition. Carpenter points out that the PQR cluster of 3 neurons, 3 columns, or 3 modules is involved in 3 step processing or three step thinking. It is possible in thinking, deduction, neurotransmission in 3 or more cell net points to end up back at the origin or original command/integrator neurons. The PQR schematic has a logic space in the form of a
They can also be unrelated in logic space. PQR leads to S under a connectedness or unity of purpose. PQR may not yield a conclusion depending upon the relatedness of the premises or statements. Relationships between premises are either true, false, lead to a number, lead to or be an equation. Take for instance Planck’s Law E(energy in joules)= h(Planck’s constant 3.626 X 10 -34 Joules-seconds) or v( c or the speed of light/λ (the wavelength). Planck’s Law has stood the test of time. The same holds true for many of the other Laws of Physics or Laws of the Physical Universe. Planck’s formula however is based upon involved scientific experiments, not knowledge a priori or conclusions from logic space. Relatedness suggests statements can be linked in logical
