“…The ECRFs of most area 17 (Akasaki et al 2002;Bardy et al 2006Bardy et al , 2009Naito et al 2007;Nelson and Frost 1978;Sengpiel et al 1997;Sun et al 2004; see for review Seriès et al 2003) and area 18 neurons (present study) exhibited some degree of orientation tuning, and in most of those, the suppression of the sRF-induced spike responses was strongest when the gratings in the sRF and ECRF were iso-oriented. However, orientation tunings of ECRFs of areas 17 (Akasaki et al 2002;Bardy et al 2006Bardy et al , 2009Naito et al 2007;Sengpiel et al 1997; see for reviews Seriès et al 2003) and area 18 neurons (present study; cf. Sun et al 2004) are invariably substantially broader than those of their sRFs.…”

“…Putative mechanisms underlying the silent surround suppression in area 17 neurons of cats and macaques include 1) intrinsic intracortical excitation and inhibition and 2) intrinsic inhibition driven by the feedback from the "higher order" extrastriate areas, as well as 3) a reduction in the strength of feedforward excitatory drive from the LGNd (see for reviews Angelucci and Bressloff 2006;Bardy et al 2009;Ishikawa et al 2010;Seriès et al 2003;Walker et al 2000;Webb et al 2005).…”

Romo PA, Wang C, Zeater N, Solomon SG, Dreher B. Phase sensitivities, excitatory summation fields, and silent suppressive receptive fields of single neurons in the parastriate cortex of the cat. J Neurophysiol 106: 1688 -1712, 2011. First published June 29, 2011 doi:10.1152/jn.00894.2010We have recorded single-neuron activity from cytoarchitectonic area 18 of anesthetized (0.4 -0.7% isoflurane in 65% N 2 O-35% O 2 gaseous mixture) domestic cats. Neurons were identified as simple or complex on the basis of the ratios between the phase-variant (F1) component and the mean firing rate (F0) of spike responses to optimized (orientation, direction, spatial and temporal frequencies, size) high-contrast, luminance-modulated, sinewave drifting gratings (simple: F1/F0 spike-response ratios Ͼ 1; complex: F1/F0 spike-response ratios Ͻ 1). The predominance (ϳ80%) of simple cells among the neurons recorded from the principal thalamorecipient layers supports the idea that most simple cells in area 18 might constitute a putative early stage in the visual information processing. Apart from the "spike-generating" regions (the classical receptive fields, CRFs), the receptive fields of threequarters of area 18 neurons contain silent, extraclassical suppressive regions (ECRFs). The spatial extent of summation areas of excitatory responses was negatively correlated with the strength of the ECRFinduced suppression of spike responses. Lowering the stimulus contrast resulted in an expansion of the summation areas of excitatory responses accompanied by a reduction in the strength of the ECRFinduced suppression. The spatial and temporal frequency and orientation tunings of the ECRFs were much broader than those of the CRFs. Hence, the ECRFs of area 18 neurons appear to be largely "inherited" from their dorsal thalamic inputs. In most area 18 cells, costimulation of CRFs and ECRFs resulted in significant increases in F1/F0 spike-response ratios, and thus there was a contextually modulated functional continuum between the simple and complex cells. luminance-modulated gratings; simple and complex cells; spatial and temporal properties; classical and extraclassical receptive fields; primary visual cortex HUBEL AND WIESEL (1965) postulated that in the domestic cat, the so-called parastriate cortex (cytoarchitectonic area 18 of Gurewitsch and Chatschaturian 1928; cf. Otsuka and Hässler 1962) constitutes a "higher order" visual cortical area (Fig.

“…24,39 Conversely, all other conditions result in less local excitation, either through lower feedforward drive or by engaging longer range cortical circuits involved in surround suppression. 32,35,36,37,[43][44][45][46][47][48] Therefore, tuning width differences between pinwheel and domain neurons are likely generated through more local circuits and overcome through recruitment of long-range cortical circuits.…”

Differences in orientation tuning between pinwheel and domain neurons in primary visual cortex depend on contrast and size

, "Differences in orientation tuning between pinwheel and domain neurons in primary visual cortex depend on contrast and size," Neurophoton. 4(3), 031209 (2017), doi: 10.1117/1.NPh.4.3.031209. Abstract. Intrinsic signal optical imaging reveals a highly modular map of orientation preference in the primary visual cortex (V1) of several species. This orientation map is characterized by domains and pinwheels where local circuitry is either more or less orientation selective, respectively. It has now been repeatedly demonstrated that neurons in pinwheels tend to be more broadly tuned to orientation, likely due to the broad range of orientation preference of the neighboring neurons forming pinwheels. However, certain stimulus conditions, such as a decrease in contrast or an increase in size, significantly sharpen tuning widths of V1 neurons. Here, we find that pinwheel neuron tuning widths are broader than domain neurons only for high contrast, optimally sized stimuli, conditions that maximize excitation through feedforward, and local cortical processing. When contrast was lowered or size increased, orientation tuning width sharpened and became equal. These latter conditions are conducive to less local excitation either through lower feedforward drive or by surround suppression arising from long-range cortical circuits. Tuning width differences between pinwheel and domain neurons likely arise through more local circuitry and are overcome through recruitment of longer-range cortical circuits.

“…The surround orientation tuning can be independent of the tuning of the center (DeAngelis et al, 1994;Sillito et al, 1995;Sengpiel et al, 1997;Cavanaugh et al, 2002a;Hashemi-Nezhad and Lyon, 2012), and the resulting center-surround interactions are thought to be critical for figure ground segregation, forming the building blocks of form perception and optical illusions such as illusory contours and perceptual filling-in (Sillito et al, 1995;Zipser et al, 1996;Gilbert, 1998;Vinje and Gallant, 2000;Series et al, 2003). The surround is likely mediated through a combination of feedforward afferents (Nolt et al, 2004;Webb et al, 2005;Sceniak et al, 2006;Alitto and Usrey, 2008;Ozeki et al, 2009), feedback from higher visual areas (Salin et al, 1992;Angelucci et al, 2002;Cavanaugh et al, 2002b;Bardy et al, 2009), and long-range lateral connections within V1 (see below; Ts'o et al, 1986;Gilbert and Wiesel, 1989;Hirsch and Gilbert, 1991;Malach et al, 1993;Weliky et al, 1995;Toth et al, 1996;Dragoi and Sur, 2000;Somers et al, 2002;Brown et al, 2003;Series et al, 2003). However, the role each of these circuits play in the orientation tuning of the surround remains unclear.…”
