The tactic of this paper is therefore initially to concentrate on attention and only afterwards explore how consciousness might arise from inside the resulting neural model of attention. We will be able to use the qualitative features of consciousness, mentioned under the first th ...

... J1 = 6.38, A0 = 0 and A1 = 0.5. With this choice of parameters tuning curves in the second layer have approximately the same tuning width than receptive fields in the recurrent model, and are ~3.5 times larger than first-layer RFs. Notice also that by choosing T = 0 and S0 = 0, neurons in the first lay ...

... Verghese 2001, Wolfe et al. 1989). Like any information-processing system, the visual cortex is limited in the quantity of information it can process at each moment in time. A typical visual scene contains a great deal more information than we can process in a single glimpse. Therefore, neural mecha ...

This finding suggests that the processing or the signalling of a sensory change is more efficient when it is handled by an area that is engaged in enhanced gamma-band synchronization [6]. Importantly, the influence of local synchronization of behavioural responses was spatiall ...

In particular, if the same dimension remains relevant after the change, then re ...

Theories of early word learning either posit that developmental changes occur through automatic attention driven by bottom-up processing (Sloutsky & Fisher, 2005) or voluntary attention that is applied in a conscious and deliberate manner (Gelman & Medin, 1993).
