“…One lesson we are learning is that the solitons and instantons are no less holographic [ 16 ] than black holes. Our observations indicate that saturation of the entropy bound and its area‐form go well beyond gravity and are defined by fundamental aspects of quantum field theory such as unitarity and asymptotic freedom.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…This is a satisfying conclusion because the naive picture of two dimensional string theory appears to violate Bekenstein's entropy bound. There is no longer an obvious counterargument to the claim that string theory is a holographic theory [6].…”

“…The application of Bekenstein's bound to sufficiently small regions of the Universe can be found in [23][24][25][26][27][28][29]. Moreover, Fischler and Susskind have proposed a bound [24] which can formulate the holographic principle [30][31][32]. They have carefully exposed the difficulties that arise when such bounds are pushed beyond their range of validity [24,25,28].…”
