Interlacing one’s fingers can cause misperception of finger positions. Observer’s (O’s) fingers were interlaced in six different ways and experimenter (E) tapped two adjacent fingers in quick succession (e.g., tapping the right middle finger then the left ring finger). O had to state the perceived direction in which the tapping occurred, and errors were recorded. When hands were well separated, touching two adjacent fingers of one hand gave error rates of only 2.4%, and touching a finger on one hand then the other gave error rates of only 3.4%. Interlacing the fingers as if in prayer increased error rates to 9%. When hands were superimposed with finger pointing away from O’s body, error rates rose further to 30%. Observers knew which fingers were which, but they were confused about exactly where their fingers were. Thus, somatotopic was greatly superior to spatiotopic localization.

1. A Wolf, a Goat, and a Cabbage A man finds himself on a riverbank with a wolf, a goat, and a head of cabbage. He needs to transport all three to the other side of the river in his boat. However, the boat has room for only the man himself and one other item (either the wolf, the goat, or the cabbage). In his absence, the wolf would eat the goat, and the goat would eat the cabbage. Show how the man can get all these “passengers” to the other side. 2. Glove Selection There are 20 gloves in a drawer: 5 pairs of black gloves, 3 pairs of brown, and 2 pairs of gray. You select the gloves in the dark and can check them only after a selection has been made. What is the smallest number of gloves you need to select to guarantee getting the following? (a) At least one matching pair (b) At least one matching pair of each color 3. Rectangle Dissection Find all values of n > 1 for which one can dissect a rectangle into n right triangles, and outline an algorithm for doing such a dissection. 4. Ferrying Soldiers A detachment of 25 soldiers must cross a wide and deep river with no bridge in sight. They notice two 12-year-old boys playing in a rowboat by the shore. The boat is so tiny, however, that it can only hold two boys or one soldier. How can the soldiers get across the river and leave the boys in joint possession of the boat? How many times does the boat pass from shore to shore in your algorithm? 5. Row and Column Exchanges Can one transform the left table in Figure 2.1 into the right table by exchanging its rows and columns? 6. Predicting a Finger Count A little girl counts from 1 to 1000 using the fingers of her left hand as follows. She starts by calling her thumb 1, the first finger 2, middle finger 3, ring finger 4, and little finger 5.

Palm Of The Hand

The communications between the median and ulnar innervated territories on the palm of the hand have been studied anatomically and microscopically. A communicating branch is well appreciated but its description has had little emphasis in anatomical or surgical literature. 50 cadaveric palms were dissected in both sexes and an anastomotic branch was found in 45 hands. In 43 of them it originated proximally from the ulnar nerve and proceeded distally to enter the third common digital nerve; in the other two hands it left the median nerve to reach the fourth common digital nerve. By microscopic dissection we have seen that the ulnar fibres of the anastomotic branch which join the median nerve may contribute to the sensory innervation of the radial half of the ring finger and ulnar side of the middle finger on its palmar surface. We have therefore described a cutaneous area on the palm where care must be taken to avoid surgical damage to this branch.

Hand Length

Stature determination aids the person identification during forensic investigation. The human hand research is the current topic of interest among forensic scientist, forensic medicine experts and anthropologists. Based on sample size analysis, the study involved consented 60 males and 60 females, age ranged from 18 to 55 years old. Stature and hand lengths measurements were made with Stadiometer and Vernier Calipers for analysis.  From each participant, ten hand length measurements, five from left and five from right hands were taken. The five length measurements in left hand are the inter-distance between the distal traverse crease of the wrist (LH) and tip of thumb (T), index finger (I), middle finger (M), ring finger (R) & little finger (L), as abbreviated LHT, LHI, LHM, LHR and LHL. Similarly, the right hand lengths indicated as RHT, RHI, RHM, RHR, and RHL.  The data were statistically analyzed by using SPSS software, version 23 and column chart. The information about age, gender, name, and place of origin of the participants was coded for easy reference. This study finally developed regression equations to determine stature from hand anthropometry among Ilocano population in Philippines for person identification

Objective: The aim of this study was to identify the main diseases related to trigger finger. Methods: A retrospective, observational study was performed with data obtained through a computerized record of 75 patients with trigger finger diagnosis between July 2011 and October 2015. The diagnosis of metabolic syndrome was performed following National Cholesterol Education Program Adult Treatment Panel III (2001). Results: Patients’ ages ranged from 50 to 84 years, with a mean age of 63 years. The ring finger was the most affected, followed by the middle finger, index finger, and little finger. Most had a grade 2 trigger finger classified by Green; the right hand involvement was more prevalent, as was the dominant hand. The incidence in women was twice as high as in men. Arterial hypertension, diabetes mellitus, and dyslipidemia were shown to be important associated diseases, but metabolic syndrome was the main association found. Conclusions: Metabolic syndrome in the group of patients studied in this scientific article seems to be the main associated disease.

A fascinating book, entitled The Ladies Dictionary, was published in 1694 in London. The author, who identified himself only by the initials N. H., stated in his preface that he wrote the book "for the use of the Fair-Sex to serve them as a Secret Oracle to consult in all difficult cases." The book is filled with advice and "information" about many intimate topics which women of that period would have probably been too embarrassed to have asked their husbands or physicians. Many answers to questions that N. H. felt women of that period would have wished to have asked the "Learned Men" are fallacious. The following is an excellent example of the untruths offered to the readers of this book: We come now to a nicer Point which we should be difficulty brought to undertake were we not warranted by divers Learned Men who have given their Opinions about it. They tell as if it be a Male Child, that when it is come to some Perfection in the Womb, the Right-Eye of the mother would to appearance move swifter and sparkle more than the other.

Her right cheek will often glow and colour more than the other, and she a livelier Blush on all Occasions, than at another time, and is more brisk and free from sadness than if she conceiv'd a Female.

Choice Reaction Times

To investigate human motor programming, choice reaction times were measured on tasks for which subjects made choices between two alternative finger-tapping-movement sequences. The total-number-of-responses and the hierarchical editor models were tested. In Exp. 1 the choice was carried on the situations with the same total numbers of possible responses and different structural relations between alternative sequences. The right-hand reaction times in mirror choice (e.g., subject chose between the middle, index, and ring finger sequences of the left or right hand) were shorter than those in nonmirror choice (e.g., subject chose between the middle, index, and ring finger sequence on one hand and the middle, ring, and index finger sequence on the other hand); the total-number-of-responses model was not supported. In Exp. 2 two conditions had the same operation numbers of the hierarchical editor model. In Condition 1 subjects chose between the index finger of the right hand and the ring, index, and middle finger sequence of the left hand. In Condition 2 subjects chose between the index, ring, and middle finger sequences of the left or right hand. The reaction time in the former condition was shorter than that in the latter condition. Exp. 2 exhibited a counterexample of the hierarchical editor model that had been fairly robust in previous studies.

The article describes the movement of natural parenting and its confrontational ideology. The authors sought to provide a general understanding of the movement natural parenting and describe its confrontational ideology. Speaking in terms of sociology, sling parents form the imagined community and this particular ideology is the focus of the presents study. The hypothesis of the study lies in the assumption that discourse analysis of natural parenting is to discover traits of propaganda discourse. The subject of the analyzed discourse is set critically in relation to the modern practice of consumption, declares the personal position free from stereotypes and willingness to confront the dictatorial influence of consumer values on the style of parenting. The subject is prone to reflection and the generation of ideological texts. Despite the fact that natural parenting has positioned itself as anti-consumer-orientated, it creates a consumer niche of the “right” products for children. Being against some commodities, natural parenting creates demand for the other ones. Sling clothing for Moms (sling jackets), accessories and the like become the accompanying sling commodities. Natural parenting has positioned itself as focused on the child’s needs. The traditional educational discourse is marked as providing the convenience for a mother who does not love her child. Many of the arguments of the sling discourse are based on fear to fail to meet a child’s needs (or to cause harm to his\her health, to threaten his\her life), which relates it with the mainstream advertising discourse.

Abstract Background Hodgkin’s lymphoma presenting with digital ischemia and gangrene is a rare manifestation. Paraneoplastic manifestations are rare in Hodgkin’s lymphoma but can occur in the form of paraneoplastic cerebellar degeneration (PCD) and dermatomyositis/polymyositis. This case report adds an exceptional presentation of Hodgkin's lymphoma as digital ischemia and gangrene. Case presentation We report a case of a 60-year-old male patient who presented with fever, cough, shortness of breath, the pain in the right middle finger. On examination bluish-black discoloration of the right middle finger, left middle finger, ring finger, and generalized lymphadenopathy was noted. On further evaluation, he was found to have anemia, eosinophilia, and severe thrombocytopenia with a normal coagulation profile and negative rheumatological workup. Arterial Doppler of both upper limbs showed the normal study. He was diagnosed to have Hodgkin’s lymphoma on the lymph node and bone marrow biopsy. He was started on chemotherapy with partial improvement in symptoms and was lost to follow-up after 2 cycles. Conclusions Digital ischemia can be a rare paraneoplastic manifestation of Hodgkin’s lymphoma.

Experience-dependent reorganisation of functional maps in the cerebral cortex is well described in the primary sensory cortices. However, there is relatively little evidence for such cortical reorganisation over the short-term. Using human somatosensory cortex as a model, we investigated the effects of a 24 hr gluing manipulation in which the right index and right middle fingers (digits 2 and 3) were adjoined with surgical glue. Somatotopic representations, assessed with two 7 tesla fMRI protocols, revealed rapid off-target reorganisation in the non-manipulated fingers following gluing, with the representation of the ring finger (digit 4) shifted towards the little finger (digit 5) and away from the middle finger (digit 3). These shifts were also evident in two behavioural tasks conducted in an independent cohort, showing reduced sensitivity for discriminating the temporal order of stimuli to the ring and little fingers, and increased substitution errors across this pair on a speeded reaction time task.

AbstractA 2-year-old male child sustained injury to middle and ring fingers of the right hand following a road traffic accident. He had mutilated fingers with loss of middle phalanx along with proximal interphalangeal (PIP) joint, distal interphalangeal joint of middle finger, and loss of part of middle phalanx and PIP joint of the ring finger. There was dorsal tissue loss of both the fingers. With staged reconstructive strategy, we could salvage the fingers. In the initial part, the soft tissue reconstruction was done using pedicled groin flap. In the later stage, free PIP joint transfer from the second toes of both feet was used to reconstruct the bone and PIP joint of the ring and middle finger. A year following the joint transfer, the child had good functional outcome.
