“…Here (Figure 3), as in previous work (Gambino et al, 2014), we show that plateau potentials in the barrel cortex depend in part on activity of the POm division of the thalamus. POm neurons send dense axonal projections to L1 in S1 (Ohno et al, 2012;Wimmer et al, 2010b), where they spread out over multiple barrel columns and make synaptic contacts with apical dendrites of numerous L2/3 pyramidal neurons (Bureau et al, 2006;Feldmeyer, 2012;Gambino et al, 2014;Jones, 2000;Jouhanneau et al, 2014;Ohno et al, 2012;Petreanu et al, 2009;Sermet et al, 2019;Zhang and Bruno, 2019). Interestingly, neurons located in this higher-order thalamic nucleus have large receptive fields (Diamond et al, 1992;Jouhanneau et al, 2014;Masri et al, 2008), and the POm input-recipient L2/3 neurons are characterized by large and short-latency responses to multiple whisker deflections (Jouhanneau et al, 2014).…”
