Fine structure of myelinated mechanical nociceptor endings in cat hairy skin
Journal of Comparative Neurology - Tập 198 Số 1 - Trang 137-154 - 1981
Lawrence Kruger, Edward R. Perl, Mathius J. Sedivec
AbstractHigh‐threshold mechanoreceptors (mechanical nociceptors) with myelinated axons were electrophysiologically identified in hairy skin of the cat as described by Burgess and Perl ('67). Such elements possess receptive fields consisting of a number of punctate areas from which maximal firing can be elicited by intense (skin‐damaging) mechanical stimuli. The spots of the receptive field are sep... hiện toàn bộ
Periadolescent maturation of the prefrontal cortex is sex‐specific and is disrupted by prenatal stress
Journal of Comparative Neurology - Tập 521 Số 8 - Trang 1828-1843 - 2013
Julie A. Markham, Sylvina E. Mullins, James I. Koenig
AbstractThe prefrontal cortex (PFC) undergoes dramatic, sex‐specific maturation during adolescence. Adolescence is a vulnerable window for developing mental illnesses that show significant sexual dimorphisms. Gestational stress is associated with increased risk for both schizophrenia, which is more common among men, and cognitive deficits. We have shown that male, but not female, rats exposed to p... hiện toàn bộ
Cell death in the development of the posterior cortex in male and female rats
Journal of Comparative Neurology - Tập 436 Số 1 - Trang 32-41 - 2001
Joseph L. Nuñez, David M. Lauschke, Janice M. Juraska
AbstractWork from our laboratory has shown that adult male rats have 19% more neurons than female rats in the binocular region and 18% more in the monocular region of the primary visual cortex (Reid and Juraska [1992] J Comp Neurol 321:448–455; Nuñez et al., [1999] Soc Neurosci Abstr 25:229). In the current experiment, we investigated whether cell death in male and female rats (postnatal days 2–35... hiện toàn bộ
Cholinergic innervation of the monkey amygdala: An immunohistochemical analysis with antisera to choline acetyltransferase
Journal of Comparative Neurology - Tập 281 Số 3 - Trang 337-361 - 1989
David G. Amaral, Julia L. Bassett
AbstractThe organization of the cholinergic innervation of the macaque monkey amygdaloid complex was investigated by means of immunohistochemical techniques and either a polyclonal antiserum or a monoclonal antibody directed against the specific synthetic enzyme choline acetyltransferase (ChAT). Adjacent series of sections were processed histochemically for the demonstration of the degradative enz... hiện toàn bộ
Connections between the central nucleus of the amygdala and the midbrain periaqueductal gray: Topography and reciprocity
Journal of Comparative Neurology - Tập 303 Số 1 - Trang 121-131 - 1991
Tilat A. Rizvi, Matthew Ennis, Michael M. Behbehani, Michael T. Shipley
AbstractPrevious reports indicate that the midbrain periaqueductal gray and the central nucleus of the amygdala are interconnected but the organization of these projections has not been characterized. We have analyzed this reciprocal circuitry using anterograde and retrograde tracing methods and image analysis. Our findings reveal that innervation of periaqueductal gray from the central nucleus of... hiện toàn bộ
Postnatal development of the hippocampal formation: A stereological study in macaque monkeys
Journal of Comparative Neurology - Tập 519 Số 6 - Trang 1051-1070 - 2011
Adeline Jabès, Pamela Banta Lavenex, David G. Amaral, Pierre Lavenex
Expression analysis of cadherins in the songbird brain: Relationship to vocal system development
Journal of Comparative Neurology - Tập 508 Số 2 - Trang 329-342 - 2008
Eiji Matsunaga, Kazuo Okanoya
AbstractSongbirds learn their songs as juveniles. The brains of songbirds have a series of nuclei and neural circuits called the song system, which is indispensable for vocal learning and production. In the present study we analyzed the expression patterns of cell adhesion molecules, cadherins, in the Bengalese finch (Lonchura striata var. domestica) to investigate their potential involvement in s... hiện toàn bộ
Localized brain activation specific to auditory memory in a female songbird
Journal of Comparative Neurology - Tập 494 Số 5 - Trang 784-791 - 2006
Nienke J. Terpstra, Johan J. Bolhuis, Katharina Riebel, Jorien M.M. van der Burg, Ardie M. den Boer‐Visser
AbstractSong acquisition in songbird males is a prominent model system for the study of the brain mechanisms of memory. Male zebra finches (Taeniopygia guttata) learn their songs from an adult conspecific tutor early in life. Previous work has shown that exposure of males to their tutor song leads to increased expression of immediate early genes (IEGs) in the caudomedial nidopallium (NCM) and in t... hiện toàn bộ
Brain distribution and evidence for both central and neurohormonal actions of cocaine‐ and amphetamine‐regulated transcript peptide in Xenopus laevis
Journal of Comparative Neurology - Tập 507 Số 4 - Trang 1622-1638 - 2008
Eric W. Roubos, G Lázár, Marinella Calle, Henk Barendregt, Balázs Gaszner, Tamás Kozicz
AbstractWe tested the hypothesis that, in the amphibian Xenopus laevis, cocaine‐ and amphetamine‐regulated transcript peptide (CARTp) not only has widespread actions in the brain but also acts as a local factor in endocrine pituitary cells and/or is neurohemally secreted into the circulation to control peripheral targets. CARTp‐immunoreactive cells occur in the olfactory bulb, nucleus accumbens, a... hiện toàn bộ
Targets of horizontal connections in macaque primary visual cortex
Journal of Comparative Neurology - Tập 305 Số 3 - Trang 370-392 - 1991
B A McGuire, Charles D. Gilbert, Patricia K. Rivlin, TN Wiesel
AbstractPyramidal neurons within the cerebral cortex are known to make long‐range horizontal connections via an extensive axonal collateral system. The synaptic characteristics and specificities of these connections were studied at the ultrastructural level. Two superficial layer pyramidal cells in the primate striate cortex were labeled by intracellular injections with horseradish peroxidase (HRP... hiện toàn bộ
