Rich-club organization in effective connectivity among cortical neurons

... The performance of complex networks depends crucially on how they route their traffic, whether it is passengers, supplies, or phone calls (Barrat et al., 2008). Despite the importance of this, we have only a few clues about how information is distributed in local cortical networks, consisting of sev ...

This shows that the motor representation of a meaningful action performed by another can be generated internally in the premotor cortex of the observer (Umiltà, Kohler, Gallese, Fogassi, Keysers & Rizzolati, 2001). In addition, researchers found that mirror neuron activity was also present when a so ...

It has been proposed that the increased level of cytosolic cathepsin D in the aged rat brain is due to the age-depen ...

Although the precise mechanism of delayed neuronal degeneration in the SNR following MCA occlusion is not known, there is increasing evidence that the excessive excitation induced by a loss of an inhibitory GABAergic input from the neostriatum and/or the globus pallidus plays a major role. The delay ...

Artificial general intelligence

Artificial general intelligence (AGI) is the intelligence of a (hypothetical) machine that could successfully perform any intellectual task that a human being can. It is a primary goal of artificial intelligence research and an important topic for science fiction writers and futurists. Artificial general intelligence is also referred to as ""strong AI"", ""full AI"" or as the ability to perform ""general intelligent action"".Some references emphasize a distinction between strong AI and ""applied AI"" (also called ""narrow AI"" or ""weak AI""): the use of software to study or accomplish specific problem solving or reasoning tasks. Weak AI, in contrast to strong AI, does not attempt to perform the full range of human cognitive abilities.
