Infra‐slow modulation of fast beta/gamma oscillations in the mouse visual system

Abstract: Key points Neurophysiological activity in the subcortical visual system fluctuates in both infra‐slow and fast oscillatory ranges, but the level of co‐occurrence and potential functional interaction of these rhythms is unknown. Analysing dark‐adapted spontaneous activity in the mouse subcortical visual system, we find that these two types of oscillation interact uniquely through a population of neurons expressing both rhythms. Genetic ablation of rod/cone signalling potentiates infra‐slow and abolishes fast b… Show more

“…This stimulation pattern was designed to mimic the natural arrival of retinal excitatory postsynaptic currents seen in vivo where the retinothalamic pathway is intact and the LGN activity follows the retinal infra-slow oscillation, with a period of about 2 min (Blasiak & Lewandowski, 2013;Chrobok et al, 2018;Lewandowski & Błasiak, 2004;Orlowska-Feuer et al, 2021). High-frequency (beta/ gamma) oscillations are also imposed by the retina on the LGN activity in vivo (Chrobok et al, 2018;Orlowska-Feuer et al, 2021;Saleem et al, 2017;Storchi et al, 2017); here we used lower frequency train stimulation (10 Hz), due to its highest fidelity in the slice preparation (Chrobok, Jeczmien-Lazur, Pradel, et al, 2021). Indeed, our optogenetic protocol was sufficient to excite LGN neurons throughout the whole 30-min long stimulation (Figure 6C).…”

“…This was reflected as an increase in amplitude of the fast oscillations at the acrophase of the slower rhythm; and vice versa -a decrease or diminution in amplitude of the fast oscillation at the nadir of a slower rhythm. Similarly, in the SVS, infra-slow oscillations were found to gate the amplitude of gamma rhythms (Chrobok et al, 2018;Orlowska-Feuer et al, 2021). This is possible due to a bimodal distribution in firing rate at the intra-slow firing rhythm.…”

“…The other well-described retinal rhythm which is reflected in the neuronal activity of the SVS occurs in the infra-slow frequency band (<0.01 Hz). Several research groups have recorded this oscillation within the SVS structures which encompasses all three parts of the LGN (Lewandowski and Błasiak, 2004;Filippov and Frolov, 2005;Chrobok et al, 2018;Orlowska-Feuer et al, 2021), the SCN (Miller and Fuller, 1992;Tsuji et al, 2016), OPN (Szkudlarek et al, 2008(Szkudlarek et al, , 2012Chrobok et al, 2018;Orlowska-Feuer et al, 2021) and SC (Drwiega and Blasiak, unpublished observations; Figure 2). Due to its presence in the OPN, infra-slow oscillation is also measured in rhythmic changes of pupil size .…”
