"Throughout these lectures I have delighted in showing
you that the price of gaining such an accurate theory has
been the erosion of our common sense. We must accept
some very bizarre behavior: the amplification and suppres-
sion of probabilities, light reflecting from all parts of a
mirror, light travelling in paths other than a straight line,
photons going faster or slower than the conventional speed
of light, electrons going backwards in time, photons sud-
denly disintegrating into a positron-electron pair, and so
on. That we must do, in order to appreciate what Nature
is really doing underneath nearly all the phenomena we
see in the world."
The biology of aphids is bizarre: they can be born pregnant and males sometimes lack mouths, causing them to die not long after mating. In an addition to their list of anomalies, work published this week indicates that they may also capture sunlight and use the energy for metabolic purposes...
Well, at least something is recursive, which is suitable for generative art forms, fractals and evolving geometric species. Check out this long neuroscience article...
"...the primary (but certainly not the sole) adaptive value of recursive conscious processing is energy efficiency."
ABSTRACT
At the phenomenal level, consciousness can be described as a singular, unified field of recursive self-awareness, consistently coherent in a particular way; that of a subject located both spatially and temporally in an egocentrically-extended domain, such that conscious self-awareness is explicitly characterized by I-ness, now-ness and here-ness. The psychological mechanism underwriting this spatiotemporal self-locatedness and its recursive processing style involves an evolutionary elaboration of the basic orientative reference frame which consistently structures ongoing spatiotemporal self-location computations as i-here-now. Cognition computes action-output in the midst of ongoing movement, and consequently requires a constant self-locating spatiotemporal reference frame as basis for these computations. Over time, constant evolutionary pressures for energy efficiency have encouraged both the proliferation of anticipative feedforward processing mechansims, and the elaboration, at the apex of the sensorimotor processing hierarchy, of self-activating, highly attenuated recursively-feedforward circuitry processing the basic orientational schema independent of external action output. As the primary reference frame of active waking cognition, this recursive i-here-now processing generates a zone of subjective self-awareness in terms of which it feels like something to be oneself here and now. This is consciousness.
The neural mechanisms responsible for triggering visual hallucinations are poorly understood. Here, we report a unique patient whose hallucinations consist exclusively of faces, and which could be reliably precipitated by looking at trees. Using functional Magnetic Resonance Imaging (fMRI), we found that, while face hallucinations was associated with increased neural activity in a number of cortical regions, including low-level visual areas, there was significant decreased activity in the right fusiform face area, a region that is empirically defined by increase activity during veridical perception of faces. These findings indicate key differences in how hallucinatory and veridical perceptions lead to the same phenomenological experience of seeing faces, and are consistent with the hypothesis that hallucinations may be generated by decreased inhibitory inputs to key cortical regions, in contrast to the excitatory synaptic inputs underlying veridical perception. http://precedings.nature.com/documents/1827/version/1/files/npre20081827-1.pdf
