In 2014, Google bought AI company DeepMind for a reported $500m, augmenting its own AI efforts which had been bundled together into the Google Brain unit.
This concurs nicely with the evidence from genomic imprinting that neocortex size (broadly considered to be the brain unit most relevant to sociality) is inherited maternally, but the limbic system (perhaps most closely involved in male responsiveness in agonistic contexts) is paternally inherited [ 15].
Only two functioning Bird Brain units remain--one at the Edgewater Packing Company, in Monterey, and the other at the Black Hills Reptile Gardens, near Rapid City, Dakota.
Thus different brain units have responded to different selection pressures.
Lindenfors and colleagues (BMC Biology 5 20) add significantly to our appreciation of this process by showing that there are striking differences between the two sexes in the social mechanisms and brain units involved.
However, based on a larger analysis of the different brain units, they conclude that these findings cannot be regarded as evidence against the interrelation between the ADHD symptomatology and frontal-striatal networks.
In the present case, Lindenfors et al demonstrate, with appropriate controls for phylogenetic relatedness (always a problem in comparative analyses), that the number of females in a primate group correlates positively only with the relative size of the telencephalon (controlling for total brain volume), and especially with neocortex volume, and not with the volume of other major brain units.
Instead, Lindenfors et al make the novel suggestion that we might gain some insights by asking whether simple indices of the costs of sociality (typical number of females in a group) and sexual selection (number of males) correlate differentially with different brain units.
At this time, however, we are of the opinion that given the factors (chronic oxidative stress, neuroinflammation, presence of nanosize particles in critical brain units and anatomical regions) potentially accounting for the aggregation of tau, tau phosphorylation could represent an early sensor of oxidative stress with all the subsequent detrimental effects if the exposure persist.
In the present study, we propose a bundled microwire array design which is capable of long-term recording of the trigeminal ganglion and deep-brain units.
And the wondernerds at Popular Science's PopSci blog have put together a contest where they're giving away a BUGBase brain-unit as well as the first four modules (GPS, digicam, touchscreen, accelerometer).
