Article
Full-text available
Highly organized circuits of enteric neurons are required for the regulation of gastrointestinal functions, such as peristaltism or migrating motor complex. However, the factors and molecular mechanisms that regulate the connectivity of enteric neurons and their assembly into functional neuronal networks are largely unknown. A better understanding...
Article
Full-text available
Although many details remain unknown, several positive statements can be made about the laminar distribution of primate frontal eye field (FEF) neurons with different physiological properties. Most certainly, pyramidal neurons in the deep layer of FEF that project to the brainstem carry movement and fixation signals but clear evidence also support...

Lactation is a critical period during which maternal sub- or over-nutrition affect milk composition and offspring development that can have lasting health effects. The consequences of moderate high-fat, high-simple carbohydrate diet (WD) consumption by rat dams, during gestation and lactation, on milk composition and offspring blood lipidome and it...
Article
Full-text available
Fetal brain development is closely dependent on maternal nutrition and metabolic status. Maternal protein restriction (PR) is known to be associated with alterations in the structure and function of the hypothalamus, leading to impaired control of energy homeostasis and food intake. The objective of this study was to identify the cellular and molec...
Article
Objective: Maternal diet has consequences on many organs of the offspring, but salivary glands have received little attention despite the importance of the saliva secretory function in oral health and control of food intake. The objective of this work was therefore to document in rats the impact of maternal high-fat/high-sugar diet (Western Diet)...
Data
Total energy intake from corn oil containing bottle. (A) Calories intake from the corn oil bottle for 24 h at P25 in pups from western diet (WD) fed dams and pups from control diet (CD) fed dams. (B) Calories intake from the corn oil bottle for 24 h at P45 (the third day of bottle test). (C) Calories intake from the corn oil bottle for 24 h at P95...
Data
Representative photomicrographs of TH immunostaining in nucleus accumbens (NAc) and ventral tegmental area (VTA) at three different time points. (A) Photomicrograph of TH/NeuN immunostaining at the level of the VTA, −5.30 mm from Bregma. Red labeling is for NeuN, and green one for TH. The white arrow shows the exit of the third nerve. (B) Photomicr...
Data
Summary of published data concerning dopamine pathway transcripts expression. The red characters correspond to childhood period, the blue ones to adolescence, and the black ones to adult. =: corresponds to a similar transcript expression between groups, +: corresponds to a higher transcript expression in pups from high caloric diet [junk food, west...
Data
TaqMan low-density array gene list with the corresponding life technologies inventoried codes.
Article
Full-text available
Perinatal maternal consumption of energy dense food increases the risk of obesity in children. This is associated with an overconsumption of palatable food that is consumed for its hedonic property. The underlying mechanism that links perinatal maternal diet and offspring preference for fat is still poorly understood. In this study, we aim at study...
Article
Activity-dependent long-term potentiation (LTP) and depression (LTD) of synaptic strength underlie multiple forms of learning and memory. Spike-timing-dependent plasticity (STDP) has been described as a Hebbian synaptic learning rule that could account for experience-dependent changes in neural networks, but little is known about whether and how ST...
Article
Eating behavior is strongly regulated by intrinsic physiological factors and largely influenced by the individual and cultural environments. Excessive food intake and sedentary lifestyle are the main reasons for the global epidemic of obesity. The influence of family background on eating habits makes no doubt but the fact that the nutritional, meta...
Article
Full-text available
Synaptic plasticity, a main substrate for learning and memory, is commonly assessed with prolonged stimulations. Since learning can arise from few or even a single trial, synaptic strength is expected to adapt rapidly. However, it remains elusive whether synaptic plasticity occurs in response to limited event occurrences. To answer this question, w...
Article
Mycobacterium ulcerans, the etiological agent of Buruli ulcer, causes extensive skin lesions, which despite their severity are not accompanied by pain. It was previously thought that this remarkable analgesia is ensured by direct nerve cell destruction. We demonstrate here that M. ulcerans-induced hypoesthesia is instead achieved through a specific...
Article
Full-text available
The spike-timing-dependent plasticity (STDP), a synaptic learning rule for encoding learning and memory, relies on relative timing of neuronal activity on either side of the synapse. GABAergic signaling has been shown to control neuronal excitability and consequently the spike timing, but whether GABAergic circuits rule the STDP remained unknown. H...
Article
Full-text available
The aim of the present study was to evaluate the role of the nitric oxide/cyclic guanosine monophosphate pathway in corticostriatal long-term depression induction in a model of levodopa-induced dyskinesia in experimental parkinsonism. Moreover, we have also analysed the possibility of targeting striatal phosphodiesterases to reduce levodopa-induced...
Article
Full-text available
A correct interplay between dopamine (DA) and glutamate is essential for corticostriatal synaptic plasticity and motor activity. In an experimental model of Parkinson's disease (PD) obtained in rats, the complete depletion of striatal DA, mimicking advanced stages of the disease, results in the loss of both forms of striatal plasticity: long-term p...
Article
Corticostriatal projections constitute the main input to the basal ganglia, an ensemble of interconnected subcortical nuclei involved in procedural learning. Thus, long-term plasticity at corticostriatal synapses would provide a basic mechanism for the function of basal ganglia in learning and memory. We had previously reported the existence of a c...
Article
In both Parkinson disease and in animal models of Parkinson disease, there is a microglial reaction in addition to the loss of dopaminergic neurons in the ventral midbrain. To determine the pathological role of this microglial reaction, we analyzed the kinetics of microglial activation and dopaminergic cell death induced in rats with the neurotoxin...
Article
Recently, the striatum has been implicated in the spread of epileptic seizures. As the absence of functional scaffolding protein Bassoon in mutant mice is associated with the development of pronounced spontaneous seizures, we utilized this new genetic model of epilepsy to investigate seizure-induced changes in striatal synaptic plasticity. Mutant m...
Article
Corticostriatal projections constitute the major inputs to basal ganglia, an ensemble of sub-cortical nuclei involved in the learning of cognitive-motor sequences in response to environmental stimuli. Besides striatal output neurons (medium-sized spiny neurons, MSNs) in charge of the detection of cortical activity, three main classes of interneuron...
Article
The emergence of levodopa (l-DOPA)-induced dyskinesia and motor fluctuations represents a major clinical problem in Parkinson's disease (PD). While it has been suggested that the daily dose of l-DOPA can play a critical role, the mechanisms linking l-DOPA dosage to the occurrence of motor complications have not yet been explored. Using an experimen...
Article
Parkinson's disease (PD) is characterized by the bilateral degeneration of the midbrain dopamine-containing neurons with the most severe lesion in the posterolateral part of the substantia nigra pars compacta (SNpc). In humans, such lesions lead to specific motor abnormalities (i.e., akinesia, rigidity, and tremor) that are greatly improved by levo...
Article
The pathogenesis of the motor fluctuations and dyskinesias that complicate levodopa treatment for Parkinson's disease (PD) remains uncertain. To evaluate the relationship between the degree of dopamine neuron loss and the severity of dyskinesias in a rodent model of PD, Sprague-Dawley rats were lesioned unilaterally using different doses of 6-hydro...
Article
Inflammatory processes in the brain may trigger specific neuroprotective responses in glial cells. Here, we show that bacterial lipopolysaccharide strongly up-regulates glial derived neurotrophic factor (GDNF) mRNA while it down-regulates that of neurturin. Tumor necrosis factor alpha (TNFalpha) had different effects since it stimulated neurturin e...
