Gurney Introduction Neural Networks

Characterizing Deep Brain Stimulation effects in
computationally efficient neural network models.
neural network model Background:
Recent studies on the medical treatment of Parkinson's disease (PD) led to the introduction of the so called Deep Brain Stimulation (DBS) technique. This particular therapy allows to contrast actively the pathological activity of various Deep Brain structures, responsible for the well known PD symptoms. This technique, frequently joined to dopaminergic drugs administration, replaces the surgical interventions implemented to contrast the activity of specific brain nuclei, called Basal Ganglia (BG). This clinical protocol gave the possibility to analyse and inspect signals measured from the electrodes implanted into the deep brain regions. The analysis of these signals led to the possibility to study the PD as a specific case of dynamical synchronization in biological neural networks, with the advantage to apply the theoretical analysis developed in such scientific field to find efficient treatments to face with this important disease. Experimental results in fact show that the PD neurological diseases are characterized by a pathological signal synchronization in BG. Parkinsonian tremor, for example, is ascribed to be caused by neuron populations of the Thalamic and Striatal structures that undergo an abnormal synchronization. On the contrary, in normal conditions,

The residual effects of the Enron (ENE) debacle are slowly, but surely, beginning to PERMEATE the investment landscape. In many instances it is hard to know whether the secondary problems are critically severe, or just a case of paranoid investors overreacting to ghosts. In 1997, ENE was a rather ordinary gas distribution company trading at $20/share. In the 1998-2000 period, the stock rocketed to nearly $85/share, because of celebrious views about their on-line commodity trading capabilities, an 18,000-mile fiber-optic cable and ultimately, the perceived 'rewards' from the California electricity crisis. Management gradually succumbed to the temptation to artificially inflate earnings with artful 'financial engineering' techniques and, all the while, they piled up debt and preferred...

-The last day for suspicious trading on American and United Airlines. Today, three years ago, the Chicago Exchange sees the purchase of 4,516 put options on American to only 748 call - 60 times above normal. On the Pacific Exchange, the trading ratio on United is 25 times greater than normal. Later, investigators can't help but notice that no other airlines saw such trading in their put options. Analyst John Kinnucanone, quoted by the San Francisco Chronicle, said "I saw put-call numbers higher than I've ever seen in 10 years of following the markets, particularly the options market."
-The last day for suspicious trading on Morgan Stanley, one of the World Trade Center's largest tenants. Between Sept. 7 and Sept. 10, the company experiences an increase of 27 times in the purchase...

Secrets of Alleged Oil Price Manipulation Exposed
Source: CNBC/NYT
Its superfast, supersecret oil trading software was called the Hammer.
And if the Commodity Futures Trading Commission is right, the name fit well with an intricate scheme that allowed commodity traders in Chicago working for Optiver, a little-known company based in Amsterdam, to put their orders first in line and subtly manipulate the price of oil to the company’s advantage.
Oil Barrels
Transcripts and taped conversations of actions that took place in 2007, included in the commission’s case, reveal the secretive workings of high-frequency trading, a fast-growing Wall Street business that is suddenly drawing scrutiny in Washington. Critics say this high-speed form of computerized...
