Journal KeSimpulan.com - mathematical pattern serial killers. Firing activity of brain neurons treated with mathematics to explain the pattern of a serial killer.
On 20 November 1990, Andrei Chikatilo was arrested in Rostov, Russia''s border with Ukraine. After 9 days in custody, Chikatilo admitted 36 murders of women and children during the period of 12 years.
The next trial he admitted to 20 killings. So he''s one of the most prolific serial killers of modern history.
Now, Mikhail Simkin and Roychowdhury Vwani from the University of California Los Angeles, describes a mathematical analysis of the behavior patterns of Chikatilo.
Quantitative mathematical pattern follows the law exactly what happened on Chikatilo behavior caused by the firing of neurons in the brain.
When neurons fire, the fire extinguished until he no longer recharge, a time known as the refractory period. Each neuron is connected to thousands of others. Other neurons are also getting into the fire that was triggered by the first neuron.
Neurons in turn connect more and so on so it is easy to see how a chain reaction throughout the brain sweep if the conditions are ripe. But this by itself is not able to explain the behavior of serial killers.
"We can not expect the murderer committed the murder at the right time when the neural excitation reaches a certain threshold. He needs time to plan and prepare for the crime," said Simkin and Roychowdhury.
In contrast, Simkin and Roychowdhury suggest a serial killer just committed a murder after a threshold is exceeded at a particular time period. Murder has a calming effect on neuronal activity of the killer that falls below the threshold.
Simkin and Roychowdhury use period of 2 milliseconds as a basic step that is part-time real neuron firing. And simulation of the steps a few times 100 billion, equivalent to 12 years or more. This active period Chikatilo!
"The model introduces the success rate of murders occur with a certain probability. If not, he repeats his efforts on the next day and beyond," said Simkin and Roychowdhury.
Chikatilo eventually convicted of 52 murders and executed with shots to the head in 1994.Stochastic modeling of a serial killer
