Respiration-entrained brain rhythms are global but often overlooked

ABL Tort, J Brankačk, A Draguhn - Trends in neurosciences, 2018 - cell.com
We revisit recent evidence showing that nasal respiration entrains oscillations at the same
frequency as breathing in several regions of the rodent brain. Moreover, respiration …

[HTML][HTML] Synaptic plasticity, engrams, and network oscillations in amygdala circuits for storage and retrieval of emotional memories

M Bocchio, S Nabavi, M Capogna - Neuron, 2017 - cell.com
