JOHNSON, J. D. AND M. S. GAZZANIGA. Reversal behavior in split-brain monkeys. PHYSIOL. BEHAV. 6 (6) 707--709, 1971.Using split-brain monkeys, reversal behavior was observed under two conditions. In the first both hemispheres viewed the discrimination cues. Previous to this one hemisphere had been taught to respond to one cue and the other hemisphere had learned the opposite response. The task w...

Two split-brain patients who differ in their right hemisphere language capacity were tested on a variety of simple cognitive tasks. Both isolated right hemispheres performed poorly on most tests. The results suggest that the presence of language in the right hemisphere, a brain system that ordinarily does not possess such competence, need not necessarily confer the full complement of cognitive ...

The effects of emotionality and length on lateralized lexical decision of abstract nouns were investigated in 41 normal and three commissurotomized subjects. Emotionality had the same effect in both visual fields: Emotional words were responded to more accurately than neutral words. Length had different effects in the two visual fields: The accuracy of lexical decisions in the left visual field...

We used the Fsp technique to quantify the influence of changing stages of consciousness on the signal-to-noise ratio of the middle latency response (MLR). The MLR and polysomnographic activity were obtained from 10 subjects during a continuous 6-hour period. The Fsp statistic was applied to the MLR data in order to determine the number of scores above a specified criterion in each stage of cons...

the set of all non-increasing non-negative integer sequences $pi=(d_1‎, ‎d_2,ldots,d_n)$ is denoted by $ns_n$‎. ‎a sequence $piin ns_{n}$ is said to be graphic if it is the degree sequence of a simple graph $g$ on $n$ vertices‎, ‎and such a graph $g$ is called a realization of $pi$‎. ‎the set of all graphic sequences in $ns_{n}$ is denoted by $gs_{n}$‎. ‎the complete product split graph on $l‎ ...

Cross-linguistic studies of the recent decades have discovered a variety of split case marking systems, which mix nominative-accusative (S=A vs. P) and ergative-absolutive (A vs. S=P) groupings of core participant roles. The range of factors known to condition such splits in different languages includes the semantic nature of NP, its actual semantic role in the situation, tense/aspect/mood, and...

Automated nuclear segmentation is essential in the analysis of most microscopy images. This paper presents a novel concavitybased method for the separation of clusters of nuclei in binary images. A heuristic rule, based on object size, is used to infer the existence of merged regions. Concavity extrema detected along the merged-cluster boundary are used to guide the separation of overlapping re...

Recent evaluation of Neanderthal and modern human ontogeny suggests that taxon-specific features arose very early in development in both lineages, with early, possibly prenatal, morphological divergence followed by parallel postnatal developmental patterns. Here we use morphometric techniques to compare hominoid facial growth patterns, and show that this developmental phenomenon is, in fact, no...
