Spontaneous brain activity is characterized by bursts and avalanche-like dynamics, with scale-free features typical of critical behaviour. The stochastic version the celebrated Wilson-Cowan model has been widely studied as a system spiking neurons reproducing non-trivial neural activity, from avalanche dynamics to oscillatory behaviours. However, what extent such phenomena are related presence ...
Differential adhesion between migrating neurons and transient radial glial fibers enables the deployment of neurons into appropriate layers in the developing cerebral cortex. The identity of radial glial signals that regulate the termination of migration remains unclear. Here, we identified a radial glial surface antigen, SPARC (secreted protein acidic and rich in cysteine)-like 1, distributed ...
Altered thyroid statuses are associated with autonomic disorders. Thyrotropin-releasing hormone (TRH) in medullary nuclei regulates vagal efferent activity. Induction of Fos-like immunoreactivity (IR) in medullary TRH-synthesizing neurons was investigated in 24-h fasted rats with different thyroid statuses. Hypo- and hyperthyroidism were induced by 6- N-propyl-2-thiouracil (PTU) in drinking wat...
Although nicotinic agonists can modulate sensory transmission, particularly nociceptive signaling, remarkably little is known about the functional expression of nicotinic acetylcholine receptors (nAChRs) on primary sensory neurons. We have utilized molecular and electrophysiological techniques to characterize the functional diversity of nAChR expression on mammalian dorsal root ganglion (DRG) n...
Substantia nigra pars reticulata (SNr) is a key basal ganglia output nucleus critical for movement control. Its GABA-containing projection neurons intermingle with nigral dopamine (DA) neuron dendrites. Here we show that SNr GABA neurons coexpress dopamine D(1) and D(5) receptor mRNAs and also mRNA for TRPC3 channels. Dopamine induced an inward current in these neurons and increased their firin...
Binge eating afflicts approximately 5% of US adults, though effective treatments are limited. Here, we showed that estrogen replacement substantially suppresses binge-like eating behavior in ovariectomized female mice. Estrogen-dependent inhibition of binge-like eating was blocked in female mice specifically lacking estrogen receptor-α (ERα) in serotonin (5-HT) neurons in the dorsal raphe nucle...
In this study, the use of artificial neural networks in classification a superalloys whose chemical analysis is performed quality process investigated. general, spectro method alone not sufficient to determine which class steel belongs to. addition method, tests such as tensile test, hardness test or notch impact are applied. The both take time and destroy material. fact that an algorithm class...
Pachygyria or incomplete lissencephaly is a developmental condition due to abnormal migration of neurons. The association of seizures in this condition warrants investigation like electroencephalogram (EEG) and magnetic resonance imaging (MRI). 18F-flurodeoxyglucose positron emission topography computed topography (18F-FDG PET/CT) has a potential role in commenting of wide...
(Matter 1, 560–562, September 4, 2019) The affiliation of the single author Preview “Nanowires Pin Neurons: a Nano ‘Moon Landing,’” Xingcai Zhang, was incorrectly published as his prior postdoctoral position with Harvard University. At time publication, Dr. Zhang full Scientific Editor at Matter under employment Cell Press. and contact email has been revised accordingly. Editorial team apologiz...
