Time dependent sensitization (TDS) - phenomenon described originally by Chiodo and Antelman (1980) in context of dopamine receptors, refers to cascade of events that continue to develop in the organism, after the initiating stimulus is no longer available. Treatment could be recognized as such a initiating stimulus (in case of depression, example of electroconvulsive therapy would be obvious, but some aspects of pharmacotherapy too). The process leads to improvement, but, on the other hand, phenomena of kindling in recurrent depression is well known (more relapses and therapies make heavier and longer lasting subsequent episodes)...

Targeting neuropeptide systems is important for future advancements in treatment of neurological and psychiatric illnesses. However, many of the peptides and their analogs do not cross the blood-brain barrier (BBB) efficiently. Nanoparticles such as iron oxide can cross the BBB, and here we describe a novel method for the conjugation of a peptide antisauvagine-30 (ASV-30) to iron oxide nanoparticles. Previous research has shown that direct infusion of ASV-30 into the brain reduces anxiety-like behavior in animal models via actions on corticotropin releasing factor type 2 (CRF2) receptors...

OBJECTIVE: Besides seizures, patients with epilepsy are affected by a variety of cognitive and psychiatric comorbidities that further impair their quality of life. The present study provides an in-depth characterization of the behavioral alterations induced by 6 Hz corneal kindling. Furthermore, we correlate these behavioral changes to alterations in c-Fos protein expression throughout the brain following kindling. METHODS: Adolescent male Naval Medical Research Institute (NMRI) mice were kindled via repetitive subconvulsive 6 Hz corneal stimulations until they reached the fully kindled state (defined as 10 consecutive generalized seizures)...

The field of social work seeks to enhance human well-being by addressing the needs of people living in poverty. Three billion people around the world use the internet daily, and 65% of them use social media. This article qualitatively identifies emergent themes about the lived experiences of poverty from people who reported either being poor or having have been poor, using selected social media posts (N = 1,495) on the website Reddit. We found that the experiences of poverty bring arduousness and hardship, which necessitates an arsenal of survival strategies and skills...

Drug-resistant epilepsy with uncontrolled severe seizures despite state-of-the-art medical treatment continues to be a major clinical problem. Pregnancy is a state where drug pharmacokinetic changes are more pronounced and more rapid than any other period of life. The current study investigated the effect of zonisamide (ZNS) on refractory epilepsy during pregnancy in lamotrigine-resistant kindled rats. Fifty-six lamotrigine (LTG)-resistant kindled Wistar rats were divided into five experimental (four pregnant and one non-pregnant) and 2 positive controls (pregnant and non-pregnant) groups and eight intact Wistar rats were put in the negative pregnant control group...

OBJECTIVE: Homeostatic synaptic plasticity (HSP) serves as a gain control mechanism at central nervous system (CNS) synapses, including those between the dentate gyrus (DG) and CA3. Improper circuit control of DG-CA3 synapses is hypothesized to underlie epileptogenesis. Here, we sought to (1) identify compounds that preferentially modulate DG-CA3 synapses in primary neuronal culture and (2) determine if these compounds would delay or prevent epileptogenesis in vivo. METHODS: We previously developed and validated an in vitro assay to visualize the behavior of DG-CA3 synapses and predict functional changes...

Anxiety is one of the most common comorbidities of epilepsy, which has major detrimental effects on the quality of life. Generalized anxiety disorder (GAD) associated with epilepsy has been receiving most attention. However, several other forms of anxiety reportedly present in patients with epilepsy, including panic disorder (PD). In this study, using an animal model of limbic epilepsy, we examined the interplay between epilepsy and panic-like behavior (PLB). Further, considering the high degree of comorbidity between depression on the one hand, and both epilepsy and PD on the other hand, we studied whether and how the presence of PLB in animals with epilepsy would affect their performance in depression-relevant tests...

Antiepileptic drugs are the backbone for epilepsy management. Epilepsy may be accompanied by decreased pain threshold. Thus, anticonvulsant agents with antinociceptive properties are of great importance. This study investigated the possible anticonvulsant and antinociceptive effects of calcitonin in combination with either valproic acid or pregabalin and whether these effects might occur through γ-aminobutyric acid (GABA) modulation. Eighty-four male Balb/C mice were divided into 7 groups: control-naïve, pentylenetetrazole (PTZ)-induced seizures, PTZ-calcitonin, PTZ-valproic acid, PTZ-pregabalin, PTZ-calcitonin-valproic acid (PCV) combination, and PTZ-calcitonin-pregabalin (PCP) combination...

Epilepsy is a chronic brain disease characterized by repeated unprovoked seizures. Currently, no drug therapy exists for curing epilepsy or disease-modification in people at risk. Despite several emerging mechanisms, there have been few studies of epigenetic signaling in epileptogenesis, the process whereby a normal brain becomes progressively epileptic because of precipitating factors. Here, we report a novel role of histone deacetylation as critical epigenetic mechanism in epileptogenesis. Experiments were conducted using the histone deacetylase (HDAC) inhibitor sodium butyrate in the hippocampus kindling model of temporal lobe epilepsy (TLE), a classic model heavily used to approve drugs for treatment of epilepsy...

Extracellular matrix protein-integrin interaction on neurons plays an important role in the development of neuroplasticity in the brain. However, the role of fibronectin-integrin signaling in epilepsy is elusive. Here, we examined the functional role of fibronectin-integrin signaling by utilizing a combination approach involving atomic force microscopy (AFM), immunocytochemistry, and pharmacology in epileptic mouse dentate gyrus granule cells (DGGCs). There was marked increase in the fibronectin receptor α5β1-integrin staining intensity in DGGCs in epileptic mice...

Epilepsy is a chronic neurological disease which is usually associated with psychiatric comorbidities. Depsression and cognition impairment are considered to be the most common psychiatric comorbidities in epilepsy patients. However, the specific contribution of epilepsy made to these psychiatric comorbidities remains largely unknown. Here we use pentylenetetrazole (PTZ) kindling, a chronic epilepsy model, to identify neuronal nitric oxide synthase (nNOS) as a signaling molecule triggering PTZ kindling-induced cognitive impairment and depressive-like behavior...

6-[(1S)-1-[1-[5-(2-hydroxyethoxy)-2-pyridyl]pyrazol-3-yl]ethyl]-3H-1,3-benzothiazol-2-one (LY3130481 or CERC-611) is a selective antagonist of AMPA receptors containing transmembrane AMPA receptor regulatory protein (TARP) g-8 that is under development for epilepsy. The present study provided a broad inquiry into its anticonvulsant properties. LY3130481 was anticonvulsant in multiple acute seizure provocation models in mice and rats. In addition, LY3130481 was effective against absence seizures in the GAERS genetic model and in the Frings mouse model...

The present study investigated whether dietary turmeric (Curcuma longa L.) can improve rabbit reproduction, ovarian function, growth, or viability. Female New Zealand White rabbits were either fed a standard diet (n=15) or a diet enriched with 5 g (group E1) or 20 g (group E2) turmeric powder per 100 kg feed mixture (n=16 or 15, respectively). After 295 days, weight gain, conception and kindling rates, pup and mother viability, ovarian macro- and micro-morphometric indices, release of leptin in response to the addition LH, and the release of progesterone, testosterone and leptin by isolated ovarian fragments were analyzed...

Autophagy alterations have been observed in a variety of neurological disorders, however, very few studies have focused on autophagy alterations in epilepsy. The ketogenic diet (KD) likely ameliorates neuronal loss in several seizure models. However, whether this neuroprotective function occurs via starvation-induced autophagy and its prevalence in chronic kindled seizures remains unknown. The aim of this study was to determine the role of autophagy following seizure under KD, and the potential mechanism involved...

Epilepsies affect about 4% of the population and are frequently characterized by a prolonged "silent" period before the onset of spontaneous seizures. Most current animal models of epilepsy either involve acute seizure induction or kindling protocols that induce repetitive seizures. We have developed a rat model of epilepsy that is characterized by a slowly progressing series of behavioral abnormalities prior to the onset of behavioral seizures. In the current study, we further describe an accompanying progression of cytoarchitectural changes in the hippocampal formation...

REVIEW
Yorgos Dimitriadis
This article aims to define the conceptual field of jouissance in Lacanian theory, and put forth the hypothesis of a relationship between certain neurophysiological mechanisms and specific clinical phenomena where jouissance is "kindled" and outside the control of the symbolic process. First, the author briefly introduces Lacan's notion of jouissance and the way it draws on Freud's theorization, and describes the preliminary stages of this conceptual field in Lacan's work. Then, the jouissance related to two other concepts: repetition, with its Freudian and Lacanian nuances, as well as the-exclusively-Lacanian concept of the object petit a...

We describe here a simple, cost-effective apparatus for continuous tethered electroencephalographic (EEG) monitoring of spontaneous recurrent seizures in mice. We used a small, low torque slip ring as an EEG commutator, mounted the slip ring onto a standard mouse cage and connected rotary wires of the slip ring directly to animal's implanted headset. Modifications were made in the cage to allow for a convenient installation of the slip ring and accommodation of animal ambient activity. We tested the apparatus for hippocampal EEG recordings in adult C57 black mice...
