Connection weights taken in the tactile and visual mapsto the bimodal
Connection weights taken from the tactile and visual mapsto the bimodal map. The weights are uniformly distributed for the two modalities in blue and green with in average an equal quantity of weak connections (low values) and of sturdy connections (higher values). Nonetheless, for the neurons obtaining necessarily powerful links from each modalities (the red histogram), their quantity considerably diminishes. For these neurons, only eight on the neurons population (i.e eighteen neurons) have their synaptic weights above 0:4 in the two unimodal populations. For neurons obtaining their synaptic weights above 0:five, their number decreases to 8 in the neurons population (i.e eight neurons). While the international nework isn’t fully recurrent, the probability distribution describes a logcurve distribution really equivalent to smallworld and to complicated networks [82]. Complex networks are wellknown structures for efficient details processing, locally inside the subparts and globally more than the whole method [83].PLOS One particular plosone.orgSensory Alignment in SC for a Social MindPD 151746 Figure 3. Efficiency Tests for distinct configurational patterns. We execute several experiments around the three dots test, the results around the sensitivity with the bimodal neurons are averaged on twenty experiments. Within a the efficiency with the network around the black background and the three white dots, in B on the eyes only, in C on the mouth only, in D on a pitch black pattern, in E on a random pattern and in F around the reverse pattern. Bimodal neurons show a maximum intensity for the pattern A, exactly where the 3 dots match the spatial location of the eyes and of the mouth. In comparison, its constitutive patterns presented separately towards the network in B and in C generate a much reduce activity, whereas The full back pattern in D plus the random pattern in E reach an averaged activity level inside the network along with the reversed pattern in F, its lowest level. This final performance is because of the contrast polarity sensitivity on the rankorder coding neurons, which is a characteristic comparable with all the capacities of the visual program [65], but right here the method learns light elements against dark background but not dark components against light background as observed in infants [84]. doi:0.37journal.pone.0069474.gThe histogram in C draws a similar probability distribution for the spatial congruence among the visual mapping and the tactile mapping. This histogram displays the spatial error among the associated receptive fields taken from their respective barycentre (e.g Fig. 0) and normalized among It shows that the unimodal receptive fields linked by the intermediate neurons overlap mainly their spatial location with 0 error only. Apart from, the spatial distance decreases drastically above this value. As a result, most of the neurons from the two maps (90 ) are in spatial registry. Figure plots the spatial alignment amongst the visual and the tactile neurons, resp. above and below, relative to their place on PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/26846680 their respective map. The hyperlinks in between the neurons are mainly vertical and parallel and only handful of of them cross other spatial regions around the other map. So as to mark out the aligned links, we color in dark grey the links that have a little spatial displacement involving the two maps: the darker the link, the much more aligned would be the neurons.Figure 4.
