Why hearts flutter: Distorted dim motions.
When a display of red spots or hearts on a blue surround is moved around under dim light, the spots appear to wobble or flutter relative to the surround (the "fluttering hearts" effect). We explain this as follows: Rods and cones both respond to the hearts. Rods are more sluggish than cones, with a latency of ∼50 ms, and they are also much more sensitive to blue than to red (the Purkinje shift;...
متن کاملWhy is binocular visual space distorted compared to physical space ?
We propose the independent scalar learning elements summation (ISLES) model, a neural network model for the developmental learning of binocular visual space. When applied to the phenomena of Hering’s horopter and the locus of perceived egocentric equidistance, this model provides a better qualitative explanation than the Luneburg theory. This model provides physical explanations for the di2eren...
متن کاملJNK bond regulation: why do mammalian hearts invest in connexin43?
Large numbers of gap junctions interconnect working myocytes in the ventricle of adult humans.1–5 Until recently, it was assumed that the reason for the abundance of these clusters of intercellular channels was straightforward. This phenomenon was thought to be principally a matter of ensuring that action potentials were conducted efficiently from myocyte to myocyte.6–8 However, it has long bee...
متن کاملMechanism and location of atrial flutter in transplanted hearts: observations during transient entrainment from distant sites.
OBJECTIVES This study was designed to elucidate the location and mechanism of typical atrial flutter in the transplanted heart. BACKGROUND Although the F wave morphology in atrial flutter is similar in nontransplanted and transplanted hearts, the surgical incision needed for the atrial anastomosis may create a distinct electrophysiologic substrate of atrial flutter. METHODS Entrainment from...
متن کاملHearts of darkness: ‘perpetrator history’ and why there is no why
Three theories contend as explanations of perpetrator behavior in the Holocaust as well as other cases of genocide: structural, intentional, and situational. Structural explanations emphasize the sense in which no single individual or choice accounts for the course of events. In opposition, intentional/cutltural accounts insist upon the genocides as intended outcomes, for how can one explain si...
