Thalamic Network Oscillations Synchronize Ontogenetic Columns in the Newborn Rat Barrel Cortex

2013

Neocortical areas are organized in columns, which form the basic structural and functional modules of intracortical information processing. Using voltage-sensitive dye imaging and simultaneous multi-channel extracellular recordings in the barrel cortex of newborn rats in vivo, we found that spontaneously occurring and whisker stimulation-induced gamma bursts followed by longer lasting spindle bursts were topographically organized in functional cortical columns already at the day of birth. Gamma bursts synchronized a cortical network of 300-400 µm in diameter and were coherent with gamma activity recorded simultaneously in the thalamic ventral posterior medial (VPM) nucleus. Cortical gamma b…

Psychiatric Disorders in Otoneurology Patients

2005

Nearly half the patients who are in specialized otoneurologic units exhibit psychiatric disorders. The disorders are most significant in patients who have the chief symptoms of dizziness, complex forms of tinnitus, or sudden and relapsing sensorineural hearing loss. If not properly diagnosed, these disorders can lead to improper treatment, particularly when the illness is a somatoform otoneurologic disorder. Patients who have comorbid symptoms, such as reactive anxiety or depressive disorders, may experience difficulties in coping with the illness. In many instances, reactive psychologic disorders can lead to severe impairment of daily life and work activities.

Up and Down States During Slow Oscillations in Slow-Wave Sleep and Different Levels of Anesthesia

2021

Slow oscillations are a pattern of synchronized network activity generated by the cerebral cortex. They consist of Up and Down states, which are periods of activity interspersed with periods of silence, respectively. However, even when this is a unique dynamic regime of transitions between Up and Down states, this pattern is not constant: there is a range of oscillatory frequencies (0.1–4 Hz), and the duration of Up vs. Down states during the cycles is variable. This opens many questions. Is there a constant relationship between the duration of Up and Down states? How much do they vary across conditions and oscillatory frequencies? Are there different sub regimes within the slow oscillation…

Control empresarial del uso de dispositivos digitales en el ámbito laboral desde la perspectiva del derecho a la protección de datos y a la intimidad

2020

Los avances tecnológicos no sólo han permitido una evolución en los procesos productivos o en la forma organizativa y de trabajar de las empresas, sino que también han posibilitado que éstas escojan nuevas formas y métodos de supervisión de la actividad laboral más invasivos, que, en ocasiones, entran en colisión con los derechos fundamentales de los trabajadores, entre ellos, el derecho a la protección de datos y el derecho a la intimidad. La vigente Ley de Protección de Datos destina algunos preceptos a regular el control y acceso por parte de la empresa a los dispositivos digitales facilitados al trabajador. El presente trabajo analiza estos preceptos y los rasgos más destacados de su ré…

Comparison of spike parameters from optically identified GABAergic and glutamatergic neurons in sparse cortical cultures

2015

We are pleased to note that our publication “Comparison of spike parameters from optically identified GABAergic and glutamatergic neurons in sparse cortical cultures” by Weir et al. (2015) raised some discussion on the feasibility of solely electrophysiological discrimination of distinct neuronal subpopulations in vitro. We agree with Becchetti and Wanke (2015) that their report and our study on the same question were conducted with different technical approaches and that this may explain the observed differences between both studies. Although we obviously recorded a reduced spontaneous neuronal activity under our sparse culture conditions, these conditions were necessary to enable the uneq…

Self-organization of repetitive spike patterns in developing neuronal networks in vitro

2010

The appearance of spontaneous correlated activity is a fundamental feature of developing neuronal networks in vivo and in vitro. To elucidate whether the ontogeny of correlated activity is paralleled by the appearance of specific spike patterns we used a template-matching algorithm to detect repetitive spike patterns in multi-electrode array recordings from cultures of dissociated mouse neocortical neurons between 6 and 15 days in vitro (div). These experiments demonstrated that the number of spiking neurons increased significantly between 6 and 15 div, while a significantly synchronized network activity appeared at 9 div and became the main discharge pattern in the subsequent div. Repetiti…

Plasticity-Related Gene 1 Affects Mouse Barrel Cortex Function via Strengthening of Glutamatergic Thalamocortical Transmission

2016

Plasticity-related gene-1 (PRG-1) is a brain-specific protein that modulates glutamatergic synaptic transmission. Here we investigated the functional role of PRG-1 in adolescent and adult mouse barrel cortex both in vitro and in vivo. Compared with wild-type (WT) animals, PRG-1-deficient (KO) mice showed specific behavioral deficits in tests assessing sensorimotor integration and whisker-based sensory discrimination as shown in the beam balance/walking test and sandpaper tactile discrimination test, respectively. At P25-31, spontaneous network activity in the barrel cortex in vivo was higher in KO mice compared with WT littermates, but not at P16-19. At P16-19, sensory evoked cortical respo…

Inguinal hernia and certain risk factors

1992

There are several studies on inguinal hernias that give some clues about the association between this type of hernia and certain risk factors. This association was suspected long ago but had not been demonstrated. The present study tries to correlate the origin of inguinal hernias and the physical effort of the subjects in accordance with their work activity. The results of this study show that physical effort, as a risk factor, is closely related to the appearance of inguinal hernias. A person whose work involves lifting or other strenuous exertion has a higher risk than those whose jobs are less strenuous (p less than 0.05). This conclusion was reached after taking into account not only t…

The love of money and work‐related attitudes

2004

This study examines the love of money and work‐related attitudes and identifies four money profiles based on a sample of citizens in the Republic of Macedonia. Achieving Money Worshipers (the highest scores on Factors Success, Motivator, and Budget and the lowest on Evil) had the highest active involvement in work activities. Careless Money Admirers (the lowest score on Factor Budget) had the highest external locus of control, the highest involvement, and lowest success avoidance. Apathetic Money Managers (the lowest scores on Factors Success and Motivator) had the highest internal locus of control and the lowest involvement. Money Repellent Individuals (the highest score on Factor Evil) ha…
