Evolution of cooperation and competition can appear when multiple adaptive agents share a biological, social, or technological niche. In the present work we study how emerge between autonomous that learn by reinforcement while using only their raw visual input as state representation. particular, extend Deep Q-Learning framework to multiagent environments investigate interaction two learning in well-known video game Pong. By manipulating classical rewarding scheme Pong show competitive...
One fundamental feature of consciousness is that the contents depend on state consciousness. Here, we propose an answer to why this so: both and activity cortical layer 5 pyramidal (L5p) neurons. These neurons affect thalamic processing, hence coupling cortico-cortical thalamo-cortical loops with each other. Functionally corresponds between Together form a broadcasting system, where L5p cells are central elements. This perspective makes one quite specific prediction: processing does not...
How is conscious experience related to material brain processes? A variety of theories aiming answer this age-old question have emerged from the recent surge in consciousness research, and some are now hotly debated. Although most researchers so far focused on development validation their preferred theory relative isolation, article, written by a group scientists representing different theories, takes an alternative approach. Noting that various often try explain aspects or mechanistic...
ABSTRACT Artificial intelligence (AI) systems capable of generating creative outputs are reshaping our understanding creativity. This shift presents an opportunity for creativity researchers to reevaluate the key components process. In particular, advanced capabilities AI underscore importance studying internal processes paper explores neurobiological machinery that underlies these and describes experiential component It is concluded although products artificial human can be similar,...
Recent findings have implicated thalamic alpha oscillations in the phasic modulation of cortical activity. However, precise relationship between and neocortical activity remains unclear. Here we show a large sample healthy human participants ( n = 45) using spatial filtering techniques measures phase amplitude coupling that gamma-band posterior medial parietal cortex is modulated by during eyes-closed resting-state recordings. In addition, our visual was not but coupled to strong To overcome...
Recent advances in the field of artificial intelligence have revealed principles about neural processing, particular vision. Previous work demonstrated a direct correspondence between hierarchy human visual areas and layers deep convolutional networks (DCNN) trained on object recognition. We use DCNN to investigate which frequency bands correlate with feature transformations increasing complexity along ventral pathway. By capitalizing intracranial depth recordings from 100 patients we assess...
Understanding the neurobiological mechanisms underlying consciousness remains a significant challenge. Recent evidence suggests that coupling between distal–apical and basal–somatic dendrites in thick-tufted layer 5 pyramidal neurons (L5 PN ), regulated by nonspecific-projecting thalamus, is crucial for consciousness. Yet, it uncertain whether this thalamocortical mechanism can support emergent signatures of consciousness, such as integrated information. To address question, we constructed...
Which neural processes underlie our conscious experience? One theoretical view argues that the correlates of consciousness (NCC) reside in local activity sensory cortices. Accordingly, category-specific gamma band responses visual cortex correlate with perception. However, as most studies manipulated perception by altering amount evidence, it is possible they reflect prerequisites or consequences rather than actual NCC. Here we directly address this issue developing a new experimental...
Constructive theories of brain function such as predictive coding posit that prior knowledge affects our experience the world quickly and directly. However, it is yet unknown how swiftly impacts neural processes giving rise to conscious experience. Here we used an experimental paradigm where augmented perception measured timing this effect with magnetoencephalography (MEG). By correlating perceptual benefits MEG activity, found took in time-window 80-95 ms after stimulus onset, thus...
The idea that the thalamo-cortical system is crucial constituent of neurobiological mechanisms consciousness has a long history. For last few decades, however, research to large extent overlooked interplay between cortex and thalamus. Here we revive an integrated view neurobiology by presenting discussing several recent major findings about role thalamocortical interactions in consciousness. Based on these propose specific cellular mechanism how thalamic nuclei modulate integration different...
Previous studies have observed different onset times for the neural markers of conscious perception. This variability could be attributed to procedural differences between studies. Here we show that visual perception can strongly vary even within a single study. A heterogeneous stimulus set was presented at threshold contrast. Trials with and without were contrasted on 100 balanced subsets data. Importantly, stimuli did not differ in content, but only regard specific trials used. approach...
Studies have demonstrated that social media use, as well problematic smartphone use (PSU), are associated with psychopathology variables, such depression and anxiety. However, it has not been studied how Instagram frequency is depression, anxiety, PSU. The aim of this study was to investigate whether related these variables. Three hundred five active users ( M age = 23.61, SD 5.33; 82.2% female) comprised the effective sample in study. They responded an online survey included questionnaires...
