Background: Humans exhibit a remarkable ability to synchronize their actions with external auditory stimuli through a process called auditory–motor or rhythmic entrainment. Positive effects of rhythmic entrainment have been demonstrated in adults with neurological movement disorders, yet the neural substrates supporting the transformation of auditory input into timed rhythmic motor outputs are not fully understood. We aimed to systematically map and synthesize the research on the neural correlates of auditory–motor entrainment and synchronization. Methods: Following the PRISMA-ScR guidelines for scoping reviews, a systematic search was conducted across four databases (MEDLINE, Embase, PsycInfo, and Scopus) for articles published between 2013 and 2023. Results: From an initial return of 1430 records, 22 studies met the inclusion criteria and were synthesized based on the neuroimaging modality. There is converging evidence that auditory–motor synchronization engages bilateral cortical and subcortical networks, including the supplementary motor area, premotor cortex, ventrolateral prefrontal cortex, basal ganglia, and cerebellum. Specifically, the supplementary motor area and the basal ganglia are essential for beat-based timing and internally guided rhythmic movements, while the cerebellum plays an important role in tracking and processing complex rhythmic patterns and synchronizing to the external beat. Self-paced tapping is associated with additional activations in the prefrontal cortex and the basal ganglia, suggesting that tapping in the absence of auditory cues requires more neural resources. Lastly, existing studies indicate that movement rate and the type of music further modulate the EEG power in the alpha and beta frequency bands. Conclusions: These findings are discussed in the context of clinical implications and rhythm-based therapies. Full article

This essay explores the relationship between the U.S.-based Beat literary movement and the Hungry Generation literary movement centered in and around Calcutta, India, in the early 1960s. It discusses a trip Allen Ginsberg and Peter Orlovsky took to India in 1962, where they met writers associated with the Hungry Generation. It further explains how Lawrence Ferlinghetti, owner of City Lights Books in San Francisco, was inspired to start a new literary magazine, City Lights Journal, by Ginsberg’s letters from India, which included work by Hungry Generation writers. The essay shows how City Lights Journal packaged the Hungry Generation writers as the Indian wing of the Beat movement, and focuses in particular on the work of Malay Roy Choudhury, the founder of the Hungry Generation who had been prosecuted for obscenity for his poem “Stark Electric Jesus”. The essay emphasizes in particular the close relationship between aesthetics and politics in Hungry Generation writing, and suggests that Ginsberg’s own mid-1960s turn to political activism via the imagination is reminiscent of strategies employed by Hungry Generation writers.
