abstract = {The neuromodulator adenosine is widely considered to be a
key regulator of sleep homeostasis and an indicator of sleep
need. Although the effect of adenosine on subcortical areas
has been previously described, the effects on cortical
neurons have not been addressed systematically to date. To
that purpose, we performed in vitro whole-cell patch-clamp
recordings and biocytin staining of pyramidal neurons and
interneurons throughout all layers of rat prefrontal and
somatosensory cortex, followed by morphological analysis. We
found that adenosine, via the A1 receptor, exerts
differential effects depending on neuronal cell type and
laminar location. Interneurons and pyramidal neurons in
layer 2 and a subpopulation of layer 3 pyramidal neurons
that displayed regular spiking were insensitive to adenosine
application, whereas other pyramidal cells in layers 3–6
were hyperpolarized (range 1.2–10.8 mV). Broad tufted
pyramidal neurons with little spike adaptation showed a
small adenosine response, whereas slender tufted pyramidal
neurons with substantial adaptation showed a bigger
response. These studies of the action of adenosine at the
postsynaptic level may contribute to the understanding of
the changes in cortical circuit functioning that take place
between sleep and awakening.},
