Parkinson's disease (PD) is associated with procedural learning deficits. Nonetheless, studies have demonstrated that reward-related learning is comparable between patients with PD and controls (Bódi et al., Brain, 132(9), 2385-2395, 2009; Frank, Seeberger, & O'Reilly, Science, 306(5703), 1940-1943, 2004; Palminteri et al., Proceedings of the National Academy of Sciences of the United States of America, 106(45), 19179-19184, 2009). However, because these studies do not separate the effect of reward from the effect of practice, it is difficult to determine whether the effect of reward on learning is distinct from the effect of corrective feedback on learning...

INTRODUCTION: Malignant hyperthermia (MH) is an inherited hypermetabolic condition characterized by uncontrolled calcium release from the sarcoplasmic reticulum of skeletal muscle, usually from exposure to inhaled general anesthetics and/or the depolarizing neuromuscular blocking agent succinylcholine. Multiple case reports now reveal that crises may be precipitated by environmental factors such as exercise or high ambient temperatures. Common signs of an MH crisis include life-threatening hyperthermia, metabolic acidosis, muscle rigidity, and tachycardia...

Genetic chimerism is rarely considered in the analysis of population genetics data, because assumed to be an exceptionally rare, mostly benign, developmental accident. An unappreciated source of chimerism is transmissible cancer, when malignant cells have become independent parasites and can infect other individuals. Parasitic cancers were thought to be rare exceptions, only reported in dogs (Murgia et al., Cell, 2006, 126, 477; Rebbeck et al., Evolution, 2009, 63, 2340), Tasmanian devils (Pearse and Swift, Nature, 2006, 439, 549; Pye et al...

Scott D Slotnick
Analysis of functional magnetic resonance imaging (fMRI) data typically involves over one hundred thousand independent statistical tests; therefore, it is necessary to correct for multiple comparisons to control familywise error. In a recent paper, Eklund, Nichols, and Knutsson used resting-state fMRI data to evaluate commonly employed methods to correct for multiple comparisons and reported unacceptable rates of familywise error. Eklund et al.'s analysis was based on the assumption that resting-state fMRI data reflect null data; however, their 'null data' actually reflected default network activity that inflated familywise error...

In a recent study published in the Proceedings of the National Academy of Sciences of the U.S.A., Jau-Song Yu et al reported of their generated four-protein biomarker panel consisting of MMP1, KNG1, ANXA2, and HSPA5, as based on a risk-score scheme they established (Yu et al, 2016). This panel showed high sensitivity (87.5%) and specificity (80.5%) values in a test set to distinguish OSCC patients' saliva samples from non-OSCC patients' saliva samples. The risk score >0.4 detected 84% of the stage I OSCCs and a significant portion (42%) of the high-risk, visible, oral potentially-malignant disorders (OPMDs)...

REVIEW
Erik D Thiessen
Statistical learning has been studied in a variety of different tasks, including word segmentation, object identification, category learning, artificial grammar learning and serial reaction time tasks (e.g. Saffran et al. 1996 Science 274: , 1926-1928; Orban et al. 2008 Proceedings of the National Academy of Sciences 105: , 2745-2750; Thiessen & Yee 2010 Child Development 81: , 1287-1303; Saffran 2002 Journal of Memory and Language 47: , 172-196; Misyak & Christiansen 2012 Language Learning 62: , 302-331). The difference among these tasks raises questions about whether they all depend on the same kinds of underlying processes and computations, or whether they are tapping into different underlying mechanisms...

Generating words according to a given rule relies on retrieval-related search and postretrieval control processes. Using fMRI, we recently characterized neural patterns of word generation in response to episodic, semantic, and phonemic cues by comparing free recall of wordlists, category fluency, and letter fluency [Shapira-Lichter, I., Oren, N., Jacob, Y., Gruberger, M., & Hendler, T.

REVIEW

BACKGROUND: Lower respiratory tract infections (LRTIs) in young children account for 1.4 million deaths annually worldwide. Antibiotics could be beneficial in preventing LRTIs in high-risk children, and may also help prevent school absenteeism and work days missed by children and/or carers. While it is well documented that the efficacy of antibiotic prophylaxis for RTIs decreases over time, there are no reviews that describe the use of antibiotic prophylaxis to prevent LRTIs in high-risk children aged 12 years and under...

A number of recent studies have highlighted the exceptional capacity and fidelity of visual long-term memory. For instance, Brady, Konkle, Alvarez, and Oliva (Proceedings of the National Academy of Sciences, 105, 14325-14329, 2008) presented participants with thousands of images for nearly 6 h and then tested their memory in a two-alternative forced choice (2AFC) task. Participants were 87% accurate, even when the foil was extremely similar to the target (e.g., when the same object was presented in a different state)...

Karen B Schloss, Daniel Hawthorne-Madell, Stephen E Palmer
How can the large, systematic differences that exist between individuals' color preferences be explained? The ecological valence theory (Palmer & Schloss, Proceedings of the National Academy of Sciences 107:8877-8882, 2010) posits that an individual's preference for each particular color is determined largely by his or her preferences for all correspondingly colored objects. Therefore, individuals should differ in their color preferences to the extent that they have different preferences for the same color-associated objects or that they experience different objects...

Neural oscillations can enhance feature recognition (Azouz and Gray Proceedings of the National Academy of Sciences of the United States of America, 97, 8110-8115 2000), modulate interactions between neurons (Womelsdorf et al. Science, 316, 1609-01612 2007), and improve learning and memory (Markowska et al. The Journal of Neuroscience, 15, 2063-2073 1995). Numerical studies have shown that coherent spiking can give rise to windows in time during which information transfer can be enhanced in neuronal networks (Abeles Israel Journal of Medical Sciences, 18, 83-92 1982; Lisman and Idiart Science, 267, 1512-1515 1995, Salinas and Sejnowski Nature Reviews...

We respond to commentaries from the American Academy of Nursing, the American Association of Colleges of Nursing, and the National Institute of Nursing Research on our thoughts about integrating emerging areas of science into nursing PhD programs. We identify areas of agreement and focus our response on cross-cutting issues arising from cautions about the unique focus of nursing science and how best to proceed with incorporation of emerging areas of science into nursing PhD programs.

RANDOMIZED CONTROLLED TRIAL
Sage E P Boettcher, Jeremy M Wolfe
In "hybrid search" (Wolfe Psychological Science, 23(7), 698-703, 2012), observers search through visual space for any of multiple targets held in memory. With photorealistic objects as the stimuli, response times (RTs) increase linearly with the visual set size and logarithmically with the memory set size, even when over 100 items are committed to memory. It is well-established that pictures of objects are particularly easy to memorize (Brady, Konkle, Alvarez, & Oliva Proceedings of the National Academy of Sciences, 105, 14325-14329, 2008)...

I A Kuznetsov, A V Kuznetsov
We developed a mathematical model for simulating neuropeptide transport inside dense core vesicles (DCVs) in axon terminals containing en passant boutons. The motivation for this research is a recent experimental study by Levitan and colleagues (Bulgari et al., 2014) which described DCV transport in nerve terminals of type Ib and type III as well as in nerve terminals of type Ib with the transcription factor DIMM. The goal of our modeling is validating the proposition put forward by Levitan and colleagues that the dramatic difference in DCV number in type Ib and type III terminals can be explained by the difference in DCV capture in type Ib and type III boutons rather than by differences in DCV anterograde transport and half-life of resident DCVs...
