Functional relevance of cross-modal plasticity in blind humans
1997
Functional imaging studies of people who were blind from an early age have revealed that their primary visual cortex can be activated by Braille reading and other tactile discrimination tasks1. Other studies have also shown that visual cortical areas can be activated by somatosensory input in blind subjects but not those with sight2,3,4,5,6,7. The significance of this cross-modal plasticity is unclear, however, as it is not known whether the visual cortex can process somatosensory information in a functionally relevant way. To address this issue, we used transcranial magnetic stimulation to disrupt the function of different cortical areas in people who were blind from an early age as they i…
Does viotin activate violin more than viocin? On the use of visual cues during visual-word recognition.
2013
The vast majority of neural and computational models of visual-word recognition assume that lexical access is achieved via the activation of abstract letter identities. Thus, a word’s overall shape should play no role in this process. In the present lexical decision experiment, we compared word-like pseudowords like viotín (same shape as its base word: violín) vs. viocín (different shape) in mature (college-aged skilled readers), immature (normally reading children), and immature/impaired (young readers with developmental dyslexia) word-recognition systems. Results revealed similar response times (and error rates) to consistent-shape and inconsistent-shape pseudowords for both adult skille…
Somatosensory amplification - An old construct from a new perspective.
2017
The paper reviews and summarizes the history and the development of somatosensory amplification, a construct that plays a substantial role in symptom reports. Although the association with negative affect has been supported by empirical findings, another key elements of the original concept (i.e. body hypervigilance and the tendency of focusing on mild body sensations) have never been appropriately addressed. Recent findings indicate that somatosensory amplification is connected with phenomena that do not necessarily include symptoms (e.g. modern health worries, or expectations of symptoms and medication side effects), and also with the perception of external threats. In conclusion, somatos…
Hearing loss in Fabry disease: data from the Fabry Outcome Survey
2006
Hearing loss is a common symptom in Fabry disease, but neither its natural course nor its aetiology has been defined precisely. The aim of this study was to provide a detailed epidemiological description of hearing impairment in patients in the Fabry Outcome Survey (FOS), which is the largest available database of Fabry patients. Questionnaires were completed by 566 Fabry patients, of whom 316 reported ear-related symptoms. Pure-tone audiograms from 86 patients, performed before starting enzyme replacement therapy, were analysed and compared with age- and sex-specific normal values (International Organization for Standardization, ISO 7029). When compared to an age-matched population (ISO 70…
Long-term functional results of digital replantation: A survey of 28 patients
2019
We sought to evaluate the long-term quality of life and functional outcome of patients who underwent digital replantation after amputation. A retrospective single-center study was conducted of patients treated between January 2010 to May 2016. Twenty-eight patients who underwent successful replantation after single or multiple digital amputation were reviewed in person after at least 2years' follow-up (mean 4.6years). Total active range of motion, grip and pinch strength were assessed. Functional outcomes were evaluated using the SF-36 and DASH questionnaires. The patients' occupational status and daily activities were reported. Mean total active range of motion was 42% of the contralateral…
Effects of a three-month active rehabilitation program on psychomotor performance of lower limbs in subjects with low back pain: a controlled study w…
1998
Proper psychomotor performance is needed in work and in activities of daily living, but among subjects with low back pain this area has been studied Little. The present purpose was to evaluate the effect and permanence of a 3-mo. physical exercise program on the psychomotor performance of lower limbs in subjects with low back pain. The associations between psychomotor performance and intensity of low back pain and subjective disability were also evaluated. 90 subjects with nonspecific, subacute low back pain were assigned to one of the three groups: one given three months intensive training, one home exercise, or the control group. Four measurement sessions were made during the 1-yr. study…
Incidence of savant syndrome in Finland
2000
The general incidence of Savant Syndrome was assessed in Finland. First, a survey was made of all 583 facilities which served people with mental retardation. Second, letters asking for information regarding people with Savant Syndrome were published in two key Finnish journals of the field. We received reports of 45 cases of Savant Syndrome. This makes an incidence rate of 1.4 per 1,000 people with mental retardation. The most common form of exceptional skills was calendar calculation, followed by feats of memory.
Combined EEG and MEG analysis of early somatosensory evoked activity in children and adolescents with focal epilepsies
2006
Abstract Objective The study aimed to evaluate differences between EEG and MEG analysis of early somatosensory evoked activity in patients with focal epilepsies in localizing eloquent areas of the somatosensory cortex. Methods Twenty-five patients (12 male, 13 female; age 4–25 years, mean 11.7 years) were included. Syndromes were classified as symptomatic in 17, idiopathic in 2 and cryptogenic in 6 cases. 10 patients presented with malformations of cortical development (MCD). 122 channel MEG and simultaneous 33-channel EEG were recorded during tactile stimulation of the thumb (sampling rate 769 Hz, band-pass 0.3–260 Hz). Forty-four hemispheres were analyzed. Hemispheres were classified as t…
Sensory-specific satiety with simple foods in humans: no influence of BMI?
2007
Olfacto-gustatory sensory-specific satiety plays an important role in the termination of food ingestion. A defect in this mechanism, by increasing food intake, could be a factor in development of overweight. The present study was conducted to explore whether sensory-specific satiety in the overweight may be different from that in normal-weight subjects. 144 subjects (half men, half women; age range: 17–62 years; BMI range: 17–39 kg m−2). Olfactory pleasure (OP) and flavor pleasure (FP) were evaluated before and after ingestion of a single chosen food. Six foods from three classes were offered: cucumber and tomato, pineapple and banana, and peanut and pistachio. According to the subjects' pr…
Sensory profiles and immune-related expression patterns of patients with and without neuropathic pain after peripheral nerve lesion
2019
In this multicenter cross-sectional study, we determined sensory profiles of patients with (NL-1) and without neuropathic pain (NL-0) after nerve lesion and assessed immune-related systemic gene expression. Patients and matched healthy controls filled in questionnaires and underwent neurological examination, neurophysiological studies, quantitative sensory testing, and blood withdrawal. Neuropathic pain was present in 67/95 (71%) patients (NL-1). Tactile hyperalgesia was the most prominent clinical sign in NL-1 patients (P < 0.05). Questionnaires showed an association between neuropathic pain and the presence of depression, anxiety, and catastrophizing (P < 0.05 to P < 0.01). Neuropathic pa…
