From what I know of my study of the human brain, the amygdala, thalamus, hypothalamus, periaqueductal gray (PAG), prefrontal cortex (PFC), and dorsal vagal complex (DVC) all take part in processing fear, anger, and aggression. The five senses of the body, touch, smell, hearing, seeing, provide input to the brain. The amygdala processes the stimuli which are primarily responsible for creating flight or fight, starting with the instinct to freeze.

The amygdala is the part of the brain, close to the brain stem, that is responsible for Flight or Fight. It comprises several substructures, notably the central amygdala (CeA), centrolateral amygdala (CeL), centromedial amygdala (CeM), basolateral amygdala (BLA), and the bed nucleus of the stria terminalis (BNST). I have closely approximated these brain structures with the artificial neural network and they seem to work in conjunction with one another to produce the required instincts.

Today I had a breakthrough in the lab as I tried an extra coupling measure to join the BNST circuitry to the nervous system. The earlier arrangement amongst neural connections to the specimen’s nervous system was inappropriate… It always led to critical failure when the specimen became overexcited with fear. Instead of leading to the automatic reflexes kicking in as I activated the flight or fight circuitry, half the ‘nerve’ endings would fry, resulting in critical failure.

The problem stems from too much of an inrush of positronic energy when the stimuli are extreme. It should initiate an anxiety-like response similar to adrenaline being released into the human body, but so far it just overloads the neural network and the connections fail. The problem seems to occur in the robotic equivalent of the BNST.

It’s apparent that the energy buildup is sudden… Too sudden too effectively dissipate the energy. At first the positronic neural pathways as I have designed seemed to work as the specimen would temporarily freeze, like expected. Increasing the stimuli results in the flow of positrons accordingly until a certain point and then flash over of the circuit conductors happen as the conductors saturate and cannot hold anymore energy. I tried micro insulation of each conductor with positive results, but flash over still occurs.

I have one novel being edited, 5 more flushed out, 56 short stories, and 530 poems. Please take the time to explore and get to know me through my writing.
