Love this one!! Is Facebook making us smarter? Or do smart people understand Facebook more? New research shows that there is a correlation between people with large, online social networks and intelligence.
"[...] When you look at a Neural Network, you'll find that it is also an Asymmetric Network. Neurons have their axons that allow them to connect to other neurons, at the same time, other neurons have the freedom to connect their own axons back to the neurons connecting to them or choose other not connected neurons to hook up with.
It seems like Twitter is imitating nature's success in implementing this type of social network architecture. The most common neurons in the brain (called multipolar neurons) process their in-coming and out-coming connections separately. On a neuron, dendrites are receptors for in-coming connections and the axon branches out-coming connections. [...]"
The Internet revolution is the fastest economic change humans have experienced, and it is accelerating. Two billion people are online today, he noted; he predicts that number will double over the next decade.

The Augmented Mind is the active personal and collective cognitive environment that electronic technologies have weaved in and around us via the Internet in particular and electricity in general. It functions both as an extended memory and a processing intelligence for each one of the users of electronic technologies from the telegraph to “cloud computing” and Twitter. It brings people together instead of separating them as the alphabet did and it allows for any number of individual entries in a fluid information space definable for individual as well as collective and collective needs. It can take many forms whether pooling individual resources in services such as Wikipedia or externalizing and objectifying our imaginary processes in fictional but live environments such as Second Life.
An article published in Science Magazine in June provides evidence that the Internet has become an “external part” of our memory systems. Rather than remembering information, we seem to have “outsourced” this effortful task to an entity other than ourselves.
On the face of it, this is not an astounding finding in that psychologists have demonstrated for over 30 years that we use outside sources, such as family or team members, to supplement our less-than-perfect memories.
Although graph theory has been around since the eighteenth century, the field of network science is more recent and continues to gain popularity, particularly in the field of neuroimaging. The field was propelled forward when Watts and Strogatz introduced their small-world network model, which described a network that provided regional specialization with efficient global information transfer. This model is appealing to the study of brain connectivity as the brain can be viewed as a system with various interacting regions that produce complex behaviors. In practice, graph metrics such as clustering coefficient, path length and efficiency measures are often used to characterize system properties. Centrality metrics such as degree, betweenness, closeness, and eigenvector centrality determine critical areas within the network. Community structure is also essential for understanding network organization and topology...
La cultura digital es la fase cognitiva de la electricidad. Del mismo modo que damos por superada la fase muscular (calor, luz y energía), restamos importancia a esta nueva fase. La mayoría de la gente sólo se preocupa de su cuerpo cuando tiene dolor de espalda, o de su coche cuando tienen que llevarlo al taller. E incluso entonces, no quieren saber. Pero hay razones para la esperanza. Seguramente la transformación se está produciendo con la inevitabilidad e inconsciencia que se dieron cuando, en la época del Concilio de Trento, los sabios pretendieron imponer un nuevo orden en una religión socavada a una velocidad cada vez mayor por una concepción del ser humano totalmente nueva. Al igual que entonces, hoy asistimos, sin plantearnos dudas, a la implantación del estado conectado y globalizado de la humanidad.
