The properties of retrograde amnesia after damage to the hippocampus have been explicated with some success using a rat model of human medial temporal lobe amnesia. We review the results of this experimental work with rats focusing on several areas of consensus in this growing literature. We evaluate the theoretically significant hypothesis that…

It has been hypothesized that cerebral lateralization of function enhances cognitive performance. Evidence was found in birds and fish. However, recent research in humans did not support this hypothesis. We aimed to replicate and extend these findings for single- and dual-task performance in an ecologically relevant task. We combined a word…

Prior studies have indicated brain abnormalities underlying social processing in autism, but no fMRI study has specifically addressed the differential processing of direct and averted gaze, a critical social cue. Fifteen adolescents and adults with autism and 14 typically developing comparison participants viewed dynamic virtual-reality videos…

Concussions are a major public health concern in the United States, especially among children and adolescents. Although there is a growing body of literature regarding the underlying physiologic processes that occur after a concussion, there is no consensus regarding the risk factors for a concussion or the reasons for significant differences in…

Intracranial surgery means any surgery performed inside the skull to treat problems in the brain and surrounding structures. Aim: Evaluate the impact of nursing educational program on reducing or preventing postoperative complications for patients after intracranial surgery. Subjects and methods: Sixty adult patients had intracranial surgery (burr…

Cranial nerve (CN) knowledge is essential for students in health professions. Gestures and body movements (e.g., mime) have been shown to improve cognition and satisfaction with anatomy teaching. The aim of this pilot study was to compare the effectiveness of didactic lecturing with that of miming lecturing for student learning of the CNs. The…

We study the dynamics in an educational partnership between a university and a developing region. We examine how the university achieves its goals to improve and advertise its offerings while recruiting a cohort of students from the developing region and maintaining a sustainable relationship with the region and its students. We show that mutually…

Increased ADHD symptomology and lower IQ have been reported in internationally adopted (IA) children compared to non-adopted peers (Hostinar, Stellern, Schaefer, Carlson & Gunnar, 2012; Kreppner, O'Connor & Rutter, 2001). However, it is unclear whether these outcomes are due to institutional deprivation specifically or to co-occurring…

The purpose of the proposed study is to add to the literature regarding the assessment of effort and malingering in the field of neuropsychology using the Rey Complex Figure Test (RCFT). The majority of the literature on this measure has been in the specific areas for which the instrument was developed, namely those of visual spatial and…

The objective of this study is to examine the effect of gravity compensation training on reaching and underlying changes in muscle activation. In this clinical trial, eight chronic stroke patients with limited arm function received 18 sessions (30 min) of gravity-compensated reach training (during 6 weeks) in combination with a rehabilitation…

Several empirical lines of investigation support the idea that syllable-sized units may be involved in visual word recognition processes. In this perspective, the present study aimed at investigating further the nature of the process that causes syllabic effects in reading. To do so, the syllable frequency effect was investigated in French using…

Localist models of spreading activation (SA) and models assuming distributed representations offer very different takes on semantic priming, a widely investigated paradigm in word recognition and semantic memory research. In this study, we implemented SA in an attractor neural network model with distributed representations and created a unified…

To understand the neural basis of human speech control, extensive research has been done using a variety of methodologies in a range of experimental models. Nevertheless, several critical questions about learned vocal motor control still remain open. One of them is the mechanism(s) by which neurotransmitters, such as dopamine, modulate speech and…

Electroencephalographic recordings (EEG) were used to assess age-associated differences in nonlinear brain dynamics during both rest and auditory oddball performance in children aged 9.0-12.8 years, younger adults, and older adults. We computed nonlinear coupling dynamics and dimensional complexity, and also determined spectral alpha power as an…

Perspective-taking has become a main focus of studies on moral judgments. Recent fMRI studies have demonstrated that individual differences in brain activation predict moral decision making. In particular, pharmacological studies highlighted the crucial role for the neuropeptide oxytocin in social behavior and emotional perception. In the present…
