    • ...Although there is ample evidence for the existence of such gating systems – almost all sensory information, for example, is thought to be gated in the thalamic nuclei on its way to the forebrain [35] – this is a mere assumption in the case of magnetic information...

    • ...Rt may also regulate activity, not only in specific thalatoo-cortical relay nuclei (Singer 1979), but in several "non-specific" thalamic nuclei...
    • ...Brainstem connections of Rt have received less attention, although in the cat physiological and anatomical studies indicate some pathways that project to Rt (Singer 1979; Steriade and Deschenes 1984; Steriade et al. 1986; Pare et al. 1988)...
    • ...The brainstem reticular formation is known to be involved in the regulation of different stages of cortical activity via pathways which, in some cases, include Rt (see Steriade and Deschenes 1984 for review) and specific influences on defined aspects of visual functions via visual Rt have been suggested (Singer 1979)...

    • ...Singer (1979) proposed that acetylcholine (ACh) might act as a "permissive agent" to facilitate changes in other, non-cholinergic synapses...

    • ...This is in line with the idea that substances like ACh act as "permissive agents" that permit other pathways to change without being changed themselves (Singer 1979)...

    • ...For instance, an ocular dominance (OD) shift in area 17 after monocular deprivation (MD) seems to require that the animal attends to visual stimuli and uses vision to guide behavior (Singer 1979; Singer et al. 1982; Singer 1982)...
    • ...of the visual cortex depend upon the presence of extra-retinal "gating,' signals which convey information about the behavioral state of the animal (Singer 1979)...
    • ...This was unexpected, since tonic discharges of intralaminar neurons are commonly believed to increase the responsiveness of cortical neurons to sensory stimuli (Singer 1979)...
    • ...The polysynaptic components of the evoked potential, believed to be modulated by the "non-specific" cortical projections (Singer et al. 1976; Singer 1979), were facilitated on both sides...
