Genetic counselling in ALS: facts, uncertainties and clinical suggestions

2013

The clinical approach to patients with amyotrophic lateral sclerosis (ALS) has been largely modified by the identification of novel genes, the detection of gene mutations in apparently sporadic patients, and the discovery of the strict genetic and clinical relation between ALS and frontotemporal dementia (FTD). As a consequence, clinicians are increasingly facing the dilemma on how to handle genetic counselling and testing both for ALS patients and their relatives. On the basis of existing literature on genetics of ALS and of other late-onset life-threatening disorders, we propose clinical suggestions to enable neurologists to provide optimal clinical and genetic counselling to patients and…

Detrimental noise effects on brain's speech functions.

2009

Background noise has become part of our everyday life in modern societies. Its presence affects both the ability to concentrate and communicate. Some individuals, like children, the elderly, and non-native speakers have pronounced problems in noisy environments. Here we review evidence suggesting that background noise has both transient and Sustained detrimental effects on central speech processing. Studies on the effects of noise on neural processes have demonstrated hemispheric reorganization in speech processing in adult individuals during background noise. During noise, the well-known left hemisphere dominance in speech discrimination became right hemisphere preponderant. Furthermore, l…

Contribution of area 19 to the foreground-background-interaction of the cat: an analysis based on single cell recordings and behavioural experiments.

1990

The contribution of area 19 to pattern discrimination in the cat was studied by single cell recordings in this area and by behavioural experiments before and after bilateral lesions. In order to make quantitative comparisons between behavioural performance and that of cell systems, we introduced a new parameter that characterizes visual neurons by their signal-to-noise (S/N) thresholds. A structured visual background made up of Gaussian visual broadband noise which could be moved was superimposed on the signal (moving bars or outline patterns) and the S/N characteristics of the response were determined by varying the signal intensity. The detection performance of cats after bilateral lesion…

Color-discrimination threshold determination using pseudoisochromatic test plates

2014

We produced a set of pseudoisochromatic plates for determining individual color-difference thresholds to assess test performance and test properties, and analyzed the results. We report a high test validity and classification ability for the deficiency type and severity level [comparable to that of the fourth edition of the Hardy–Rand–Rittler (HRR) test]. We discuss changes of the acceptable chromatic shifts from the protan and deutan confusion lines along the CIE xy diagram, and the high correlation of individual color-difference thresholds and the red–green discrimination index. Color vision was tested using an Oculus HMC anomaloscope, a Farnsworth D15, and an HRR test on 273 schoolchildr…

A Unified Theory of Psychophysical Laws in Auditory Intensity Perception.

2020

Psychophysical laws quantitatively relate perceptual magnitude to stimulus intensity. While most people have accepted Stevens's power function as the psychophysical law, few believe in Fechner's original idea using just-noticeable-differences (jnd) as a constant perceptual unit to educe psychophysical laws. Here I present a unified theory in hearing, starting with a general form of Zwislocki's loudness function (1965) to derive a general form of Brentano's law. I will arrive at a general form of the loudness-jnd relationship that unifies previous loudness-jnd theories. Specifically, the "slope," "proportional-jnd," and "equal-loudness, equal-jnd" theories, are three additive terms in the ne…

Coppie miste in Italia e in Spagna. Uno studio sui fattori che favoriscono il senso di comunità dei partner stranieri

2013

Lo scopo del presente contributo è stato quello di analizzare come l’identificazione etnica (ingroup ed outgroup) e la discriminazione percepita (come straniero o come partner di coppia mista) siano legati al senso di comunità (SdC) dei partner stranieri delle famiglie interculturali residenti in Spagna e in Italia. I risultati mostrano che in entrambi i gruppi l’identificazione con il proprio gruppo etnico-culturale non è associata al SdC. Inoltre, l’aumento della discriminazione percepita come coppia mista porta ad una diminuzione del senso di comunità e della soddisfazione di vita. The aim of this paper was to analyze how ethnic identification (ingroup and outgroup) and perceived discrim…

Zasada pozytywnej dyskryminacji mniejszości narodowych w ujęciu teoretycznym i praktyce ustrojowej

2018

CEL NAUKOWY: Celem artykułu jest zbadanie teoretycznych aspektów zasady pozytywnej dyskryminacji, ustrojowych uwarunkowań jej zastosowania w odniesieniu do mniejszości narodowych w Polsce oraz dziedzin, w których może być realizowana. PROBLEM I METODY BADAWCZE: Zagadnienie pozytywnej dyskryminacji znajduje się w obrębie zainteresowania przedstawicieli wielu nauk i idealnie wpasowuje się w koncepcję demokracji ujmowanej jako wartości, procedury i w sensie substancjalnym. Nie jest ona przy tym ochroną antydyskryminacyjną, lecz jej wsparciem, promotorem równości formalnej i faktycznej. W Polsce, choć odsetek mniejszości narodowych jest nikły, pozytywna dyskryminacja ma rangę zasady w Konstytuc…

Numerical Magnitude Affects Accuracy but Not Precision of Temporal Judgments

2021

A Theory of Magnitude (ATOM) suggests that space, time, and quantities are processed through a generalized magnitude system. ATOM posits that task-irrelevant magnitudes interfere with the processing of task-relevant magnitudes as all the magnitudes are processed by a common system. Many behavioral and neuroimaging studies have found support in favor of a common magnitude processing system. However, it is largely unknown whether such cross-domain monotonic mapping arises from a change in the accuracy of the magnitude judgments or results from changes in precision of the processing of magnitude. Therefore, in the present study, we examined whether large numerical magnitude affects temporal ac…
