A Model for the Intracortical Origin of Orientation Preference and Tuning in Macaque Striate Cortex

by P. Adorjan, J. B. Levitt, J. S. Lund, K. Obermayer , 1998
"... We report results of numerical simulations for a model of generation of orientation selectivity in macaque striate cortex. In contrast to previous models, where the initial orientation bias is generated by convergent geniculate input to simple cells and subsequently sharpened by lateral circuits, ou ..."

suppression in the cat striate cortex

by John D. Allison, Kevin R. Smith, A. B. Bonds , 2001
"... A sinusoidal mask grating oriented orthogonally to and superimposed onto an optimally oriented base grating reduces a cortical neuron’s response amplitude. The spatial selectivity of cross-orientation suppression (XOR) has been described, so for this paper we investigated the temporal properties of ..."

extrastriate origin for the effect and could help explain the low-pass temporal-frequency response profile displayed by most striate cortical neurons.

Cone inputs to murine striate cortex

Background: We have recorded responses from single neurons in murine visual cortex to determine the effectiveness of the input from the two murine cone photoreceptor mechanisms ..."

Independent evolution of striated muscles in cnidarians and bilaterians

by Patrick R. H. Steinmetz, Johanna E. M. Kraus, Claire Larroux, Jörg U. Hammel, Evelyn Houliston, Gert Wörheide, Michael Nickel, Bernard M, Ulrich Technau - Nature , 2012
"... Striated muscles are present in bilaterian animals (e.g. vertebrates, insects, annelids) and some non-bilaterian eumetazoans (i.e. cnidarians and ctenophores). The striking ultrastructural similarity of striated muscles between these animal groups is thought to reflect a common evolutionary origin1, ..."

Contracture of Slow Striated Muscle during Calcium Deprivation

by Richard L. Irwin, Manfred M. Hein
"... ABSTRACT When deprived of calcium the slow striated muscle fibers of the frog develop reversible contractures in either hypertonic or isotonic solutions. While calcium deprivation continues because of a flowing calcium-free solution the muscles relax slowly and completely. Restoration of calcium dur ..."

concentrations of d-tubocurarine, procaine, or atropine. The experiments also indicate that the contractures do not originate from repetitive activity of muscle membranes. The findings are most simply explained by relating the outward movement of calcium as a link for initiating contraction in slow type striated

Electrophysiological correlates of rapid spatial orienting towards fearful faces

by Gilles Pourtois, Didier Gr, David S, Patrik Vuilleumier - Cereb. Cortex , 2004
"... We investigated the spatio-temporal dynamic of attentional bias towards fearful faces. Twelve participants performed a covert spatial orienting task while recording visual event-related brain potentials (VEPs). Each trial consisted of a pair of faces (one emotional and one neutral) briefly presented ..."
Abstract - Cited by 106 (6 self) - Add to MetaCart
-pair onset revealed a C1 component (~90 ms) that was greater for fearful than happy faces. Source localization (LORETA) confirmed an extrastriate origin of the P1 response showing a spatial validity effect, and a striate origin of the C1 response showing an emotional valence effect. These data suggest

THE INFLUENCE OF TEMPERATURE ON THE ACTION OF DIGITOXIN AND POTASSIUM ON STRIATED MUSCLE

by Samuel A. Gtjttman , 1943
"... Certain of the effects of the digitalis glycosides on the function of striated muscle resemble those resulting from an excess of potassium. As a result of studies on the action of ouabain on the energetics of contraction of the isolated frog’s sartorius muscle, Cattell (1) concluded that the charact ..."
