FRONTAL LOBE PATHOLOGY, PAROXYSMAL DISORDERS, and the EVILS OF POSITIVE FEEDBACK SU, 09/08/2011 JEFFREY A. CARMEN, PH.D. PRIVATE PRACTICE MANLIUS, NY
FRONTAL LOBE PATHOLOGY – recent evolutionary development – more software bugs PAROXYSMAL DISORDERS – (things that come on suddenly, have a strong presentation, and then leave) including migraine headaches, seizures, sudden onset violent behavior, other POSITIVE FEEDBACK – bad stuff – generally bad psychology – very bad for electronic and biological circuits – negative feedback is better
NEW YORK STATE LOTTERY The tv advertisement with the howling microphone is an example of positive feedback.
HUMAN FRONTAL LOBES THIS IS THE PART OF THE BRAIN RESPONSIBLE FOR MANAGEMENT OF THE REST OF THE BRAIN, INCLUDING EMOTIONS, SOCIAL RELATIONSIPS, AND GENERAL INHIBITION
HUMAN FRONTAL LOBES This is the most recent evolutionary development. It is easily injured. It has the most software bugs. It is supposed to shut down easily during emergencies.
FRONTAL LOBE FUNCTION LEFT FRONTAL, LEFT TEMPORAL –FUNCTIONS AND PROBLEMS RIGHT FRONTAL, RIGHT TEMPORAL –FUNCTIONS AND PROBLEMS
50,000 YEARS!!! THE HUMAN BRAIN WAS DESIGNED FOR AN ENVIRONMENT THAT EXISTED 50,000 YEARS AGO ADAPTATION TO MODERN LIFE IS ACCIDENTAL
FOUR PRIMARY DRIVES ( by KARL PRIBRAM) FEEDING

FOUR PRIMARY DRIVES THESE ARE SURVIVAL MECHANISMS THEY ARE GENERALLY INCOMPATIBLE WITH EACH OTHER THEY ARE GENERALLY INCOMPATIBLE WITH LESSER DRIVES AND EMOTIONS
PSYCHOPATHOLOGY A mismatch between a primary drive or strong habitual behavior and the internal or external environment.
ANXIETY Anxiety is one of those emotions that tends to be incompatible with other emotions. It also tends to impair activity. It shuts down the prefrontal cortex. Sexual arousal can shut down anxiety (and anxiety can shut down sexual arousal). Assertive/aggressive behavior can shut down anxiety. Most purposeful actions can shut down anxiety. Activating the prefrontal cortex can shut down anxiety.
AGGRESSION Incompatible with anxiety Rage is self reinforcing (it feels a lot better than anxiety, and there is a tension release when it is over).
DEPRESSION As a brain mechanism it is a little bit unique. In terms of brain activity, depression localizes itself as low level of activity in the left prefrontal cortex in right handed left lateralized individual.
RECIPROCITY Planning and thinking inhibit emotions. Emotions inhibit planning and thinking. One goes up, the other goes down.
HUMAN FRONTAL LOBES Chopping off a chickens head. Human frontal lobe is to the rest of the human brain as the chickens brain is to the rest of the chickens body.
DSM-IV This is the bible for classification of mental conditions. About 50% of the conditions listed represent the following: EXCESSIVE RATE AND MAGNITUDE RESPONSES TO RELATIVELY MINOR STIMULI If you remember nothing else today, remember this
DISORDERS OF RATE AND MAGNITUDE OF RESPONSE RELATED TO FRONTAL LOBE DYSFUNCTION ADHD MIGRAINE ANGER ANXIETY DEPRESSION
MIGRAINES Can mimic any other mental disorder, especially if there is an aura. Aura: progresses in a wave at 2mm to 6mm per minute, usually from back of the brain to front, ending in a headache (tsunami effect). Called CSD (cortical spreading depression). Wherever this wave passes, the brain malfunctions.
TYPICAL AND LESS TYPICAL MIGRAINE AURA GHOSTS AUDITORY HALLUCINATIONS PANIC PSYCHOTIC EPISODE SMELLS APHASIA (receptive / expressive)
