Receptive fields of neurons in cortical area V4 are large enough to fit multiple stimuli, making V4 the ideal place to study the effects of selective attention at the single-neuron level. Experiments have revealed evidence for stimulus competition and have characterized the effect thereon of spatial and feature-based attention. We developed a biophysical model with spiking neurons and conductan...

Fatal familial insomnia (FFI) is an autosomal dominant prion disease clinically characterized by rapidly progressive insomnia, prominent autonomic alterations and behavioral disturbance. The D178N mutation of the prion protein gene (PRNP) on chromosome 20 in conjunction with methionine at codon 129 is a molecular feature. Although the neuropatholo...

BACKGROUND In absence of a positive family history, the diagnosis of fatal familial insomnia (FFI) might be difficult because of atypical clinical features and low sensitivity of diagnostic tests. FFI patients usually do not fulfil the established classification criteria for Creutzfeldt-Jakob disease (CJD); therefore, a prion disease is not always suspected. OBJECTIVE To propose an update of ...

Goldberg s (2001) IPIP Big-Five personality factor markers currently lack validating evidence. The structure of the 50-item IPIP was examined in three different adult samples (total N = 906), in each case justifying a 5-factor solution, with only minor discrepancies. Age differences were comparable to previous findings using other inventories. One sample (N = 207) also completed two further per...

Focus on form has received considerable attention as researchers and theorists have enthusiastically embraced an integration of meaning-focused and form-focused instruction in the L2 classroom. Therefore, the present paper is an attempt to delve deeply into elucidating different taxonomies subsumed under the specious polarization of Focus on Form (FoF) and Focus on Forms (FoFs). It then offers ...

This study examines the relation of language arts instruction to students’ letter-word reading skill growth from the beginning of 1st grade to the end of 2nd grade using cross-classified random effects models. Amounts of teacher-managed, code-focused instruction in 1st and 2nd grade each uniquely predicted students’ letter-word reading skill growth; plus, there were child-by-instruction interac...

Do developing countries derive benefits from foreign financial investment (FFI) in the same way as they do from FDI? Through analyses in a stylized framework of foreign investment, this paper concludes that due to the lack of well functioning financial markets and the lack of technology, FFI flows may not be allocated and utilized as efficiently in developing countries as FDI. The frequently cl...
