Distinct classes of low frequency ultrasonic vocalizations in rats during sexual interactions relate to different emotional states

Michal Bialy/ Martyna Podobinska/ Jaroslaw Barski/ Wiktor Bogacki-Rychlik/ Elzbieta M. Sajdel-Sulkowska

This study examined low-frequency ultrasonic vocalizations (lUSVs) in rats during two types of sexual interactions: postejaculatory interval (PEI) and barrier – noncontact (NC) test. We report distinct classes of lUSVs that can be assigned to different emotional states; relaxation vs. frustration. Totally flat, 22-kHz calls (Class A), were observed during the relaxation state following ejaculation; characterized by immobilization or grooming during the PEI. On the other hand, two-three component(..)

Antidepressant and anxiolytic efficacy of single, chronic and concomitant use of vortioxetine, dapoxetine and fluoxetine in prenatally stressed rats

Piotr Ratajczak/ Krzysztof Kus/ Tomasz Zaprutko/ Mikołaj Szczepański/ Sandra Rusowicz/ Elżbieta Nowakowska

Depression is a highly prevalent social disease. Despite significant medical progress, therapeutic solutions for optimising treatment of this disease are still being sought. The aim of this study was to assess, using the forced swimming test, locomotor activity test and two compartment exploratory test, for a reduction in immobility time (a measure of anti-depressant efficacy), locomotor activity and anxiolytic effectiveness after single, repeated, and combined administration of vortioxetine (2.(..)

Differences in spatio-temporal distribution of the visual P3b event-related potential between young men and women

Karina Maciejewska/ Zofia Drzazga

Here, we evaluated the P3b potential evoked in a visual two-stimulus oddball paradigm. The experiment was conducted in 20 healthy students (23.1±1.1 years, 10 women), using a 32 channel electroencephalography (EEG) montage system. The paradigm included geometric figures; a black square on a white background as a target and a white circle on a black background as a standard stimulus. We examined the maximal amplitude and latency of the P3b component at 18 electrode sites, as well as, temporal cha(..)

The filled-space illusion induced by a single-dot distractor

Aleksandr Bulatov/ Vilius Marma/ Natalija Bulatova/ Lina Mickienė

In the present study, we tested the ability of our computational model of the filled-space illusion to account for data collected in experiments with stimuli comprising single-dot distractors. In three sets of experiments, we investigated this illusory effect as a function of distance between the distractor and lateral terminator of the reference spatial interval of the three-dot stimulus. We found that the model calculations properly predicted all of the observed changes in magnitude of the ill(..)

Pain catastrophizing is associated with altered EEG effective connectivity during pain-related mental imagery

Magdalena A. Ferdek/ Agnieszka K. Adamczyk/ Clementina M. van Rijn/ Joukje M. Oosterman/ Miroslaw Wyczesany

Pain catastrophizing – defined as a tendency to exaggerate the threat value or seriousness of experienced pain - has been shown to be a risk factor for pain chronification. However, the neural basis of pain catastrophizing remains unclear and requires thorough investigation. This study aimed to explore the relationship between pain catastrophizing and effective connectivity of the pain systems in healthy participants. EEG data were collected during an induced state of pain-related negative, depr(..)

Neuroprotective effects of lipopolysaccharide and naltrexone co-preconditioning in the photothrombotic model of unilateral selective hippocampal ischemia in rat

Sayed Masoud Hosseini/ Alireza Golaghaei/ Ehsan Nassireslami/ Nima Naderi/ Hamid Gholami Pourbadie/ Milad Rahimzadegan/ Saeid Mohammadi

Preconditioning with lipopolysaccharide (LPS) or opioid antagonists has a neuroprotective effect in ischemic insults. However, the co-preconditioning effect of toll-like receptor ligands and opioid antagonists has not been investigated. In this study we examined the neuroprotective effect of LPS and naltrexone (NTX) preconditioning and co-preconditioning in unilateral selective hippocampal ischemia in rats to assess for possible synergistic protective effects. LPS and NTX were injected unilatera(..)

Protective effects of M8-B, a TRPM8 antagonist, on febrile- and pentylenetetrazol-induced seizures

Nazanin Zandi/ Nosaibeh Riahi Zaniani/ Ali Moghimi/ Ali Roohbakhsh

Epilepsy is a life-threatening disorder that is marked by recurrent seizures. Febrile seizure is a common neurological disorder observed in neonates. In many cases, reducing body temperature can prevent febrile seizure. Transient receptor potential cation channel subfamily M member 8 (TRPM8) is a cation channel that is involved in body thermoregulation. It was reported that M8-B, a TRPM8 antagonist, can reduce body temperature. Thus, we aimed to investigate the effect of M8-B on different experi(..)

Selective neuronal death following exposure to methylenedioxypyrovalerone is accompanied by an inhibition of NMDA receptor NR2B subunit expression

László István Gerecsei/ Tamás Balázsa/ Diego Echevarría/ Ágota Ádám/ Gergely Zachar/ András Csillag

In a previous study, methylenedioxypyrovalerone (MDPV), a designer drug of the cathinone family, caused selective enhancement of Caspase3 immunoreactive (Casp3+) apoptotic cells in the nucleus accumbens (NAc) of 7-day-old mice. To further elaborate on the mechanism underlying MDPV-elicited apoptosis, here, we investigated the appearance of Casp3+ cells in developing neural tube explants of E12.5 mice, following MDPV treatment in vitro. Apoptotic cells appeared in large number in the pallium as r(..)

Increased short-term food intake after external lateral parabrachial subnucleus lesions in rats

Antonio D.R. Agüera/ María A. Zafra/ Filomena Molina/ Amadeo Puerto

The vagus nerve and several brainstem nuclei to which it projects have been closely associated with food intake. The aim of this study was to determine the degree to which the same or different information on food intake is processed by this nerve and by one of these nuclei, the external lateral parabrachial subnucleus (LPbNe). For this purpose, we analyzed the solid and liquid food intake of Wistar rats subjected to vagal deafferentation with capsaicin or lesions of the LPbNe. Vagotomized anima(..)
