All manuscripts must be submitted directly to Frontiers in Neuroanatomy, where they are peer-reviewed by the Associate and Review Editors of the specialty journal. PLOS Biology covers a broad range of biomedical research topics and has the highest impact factor among open-source biomedical journals. 7(46)2014.PubMed/NCBI View Article: Google Scholar. Also, the selective connectivity between many cortical neuron types has been studied in great detail. First, the PC-CC axonal field distributes in the neuropil of layers II and III and candlesticks are in close apposition to the initial axonal segment of the pyramidal cell, although somatic interactions cannot be rule out. Dendrites of pyramidal-like cells (P-L) organize into a single bundle that ascends avoiding the AOB to resolve in a trigone bounded by the edge of the OL, the AOB and the dorsal part of the anterior olfactory nucleus. No generic function for the minicolumn - i.e., one that would apply equally well to all cortical areas and species - has yet been proposed. In this study, we examined the expression patterns of neuronal maturation markers in the brain of a mouse model of dementia with Lewy body-linked mutant β-synuclein (βS), especially in the … Here, we first establish that mouse retinal ganglion cell types can be as precise about distributing their arbor volumes across the inner plexiform layer as they are about distributing the skeletons of the arbors. Finally, we have mapped our results on a recent model which considers the hypothalamus as a transverse region with alar and basal portions. 5, PMID: 21647212.]. Dendritic spines are the receptive contacts at most excitatory synapses in the central nervous system. In both Parkinsonian patients and several animal models of Parkinson's disease, the lesion of dopamine neurons produces a prolonged elevation of Gαolf levels. Behavioral data from female mouse, ferret, and human are reviewed that implicate the main olfactory system, in some cases interacting with the accessory olfactory system, in mate recognition. Here we review the current knowledge of the different sensory neuron subtypes in the mouse, the markers used to study them, and the neurogenetic strategies used to define their anatomical projections and functional roles. Recently, however, several experiments revealed that neuronal nitric oxide synthase (nNOS)-positive GABAergic neurons project cortico-cortically with long axons. This assay highlights two fundamental contributions of Rafael Lorente de Nó to neurobiology: the intrinsic organization of the mammalian cerebral cortex and the basic physiology of the neuron processes. Here we asked if particular combinations of Gli2 and Gli3 and of GliA and GliR functions contribute to the variety of hypothalamic regions, i.e., we wanted to approach the question of a possible hypothalamic version of the Shh-Gli code. 7(46)2014.PubMed/NCBI View Article: Google Scholar. Brain Struct Funct Jan 2015;220(1):351-360. doi: 10.1007/s00429-013-0659-7. Our previous study demonstrated that TBR1, a causative gene of ASD, controls axonal projection and neuronal activation of amygdala and regulates social interaction and vocal communication in a mouse model. Impact Factor. Congratulations to our authors, reviewers and editors across all Neuroscience journals – for pushing boundaries, accelerating new solutions, and helping all of us to live healthy lives on a healthy planet. While this idea was born out of experiments that cleverly combined electrophysiological recordings with anatomy, no one has 'seen' the anatomy of a column. Front Med (Lausanne). Potential implications of these findings for topics including cortical structure-function relationships, multisensory integration, functional imaging, and cortical parcellation are discussed. Although carefully collected, accuracy cannot be guaranteed. Differences in the distribution of the fibers were noted for each system. email@example.com, Tel +41(0)21 510 17 10
The use of classical and modern techniques and approaches include axonal transport methods to track the connections between brain regions; electron microscopy to obtain a more quantitative understanding of the sub-cellular and connectivity anatomy; immunocytochemistry to map protein expression patterns; in situ hybridization to map gene expression patterns; and many other powerful techniques used to examine the organization of the nervous system. On cytoarchitectual grounds the OL is divided from rostral to caudal into three distinct components: a stripe of glomerular-free cortex or preolfactory area (PA), a second or necklace glomerular area, and a wedge-shaped or interstitial area (INA) crowned by the so-called modified glomeruli that appear to belong to the anterior AOB. I sketch an approach to relate DDFs in general to their underlying potential connectivity schemes. Epub 2013 Oct 31. Editors. More recently, by capitalizing on advances in molecular techniques, researchers have identified specific ion channels and sensory receptors expressed in subsets of sensory neurons. Cholinergic fibers (CHAT) densely filled the peduncle, followed in order by serotonergic, noradrenergic, histaminergic, and orexinergic processes. This period of postnatal development is precisely the time during which Bergmann glia initiate differentiation. Image quality and powerful illustrations will be a major emphasis of Frontiers in Neuroanatomy. 19 Llorens-Martín M, Blazquez-Llorca L, Benavides-Piccione R, Rabano A, Hernandez F, Avila J and DeFelipe J: Selective alterations of neurons and circuits related to early memory loss in Alzheimer's disease. Here, we have taken an important first step towards understanding this process by triple immunostaining mouse visual cortex with a panel of antibodies, which has been used extensively for classifying developing interneurons. These two different approaches confirm that not only nNOS-positive GABAergic neurons but also other subtypes of GABAergic neurons project long axons in the cerebral cortex and are in a position to be involved in information processing. This study describes the microscopic organization of a wedge-shaped area at the intersection of the main (MOB) and accessory olfactory bulbs (AOBs), or olfactory limbus (OL), and an additional component of the anterior olfactory nucleus or alpha AON that lies underneath of the AOB. One of the most robust neuropathological findings in post-mortem human FXS and Fmr1 KO mice is the abnormal increase in dendritic spine densities, with the majority of spines showing an elongated immature … Journal Citation Reports (Clarivate Analytics, 2020) 5-Year Impact Factor: 3.908 ℹ Five-Year Impact Factor: 2019: 3.908 Asia. Until recently it was widely believed that the ability of female mammals (with the likely exception of women) to identify and seek out a male breeding partner relied on the detection of non-volatile male pheromones by the female's vomeronasal organ (VNO) and their subsequent processing by a neural circuit that includes the accessory olfactory bulb (AOB), vomeronasal amygdala, and hypothalamus.
