Abstract

Internal brain states affect sensory perception, cognition, and learning. Many neocortical areas exhibit changes in the pattern and synchrony of neuronal activity during quiet versus active behaviors. Active behaviors are typically associated with desynchronized cortical dynamics. Increased thalamic firing contributes importantly to desynchronize mouse barrel cortex during active whisker sensing. However, a whisking-related cortical state change persists after thalamic inactivation, which is mediated at least in part by acetylcholine, as we show here by using whole-cell recordings, local pharmacology, axonal calcium imaging, and optogenetic stimulation. During whisking, we find prominent cholinergic signals in the barrel cortex, which suppress spontaneous cortical activity. The desynchronized state of barrel cortex during whisking is therefore driven by at least two distinct signals with opposing functions: increased thalamic activity driving glutamatergic excitation of the cortex and increased cholinergic input suppressing spontaneous cortical activity.

  • Both cholinergic and serotoninergic systems can activate kinetically fast excitatory postsynaptic potentials in postsynaptic targets through nicotinic and 5HT3A receptors, respectively, and the discharges of both cholinergic and serotonergic neurons are strongly modulated by movement.

    “Both cholinergic and serotoninergic systems can activate kinetically fast excitatory postsynaptic potentials in postsynaptic targets through nicotinic and 5HT3A receptors, respectively, and the discharges of both cholinergic (e.g. Figure 9C) and serotonergic neurons are strongly modulated by movement (Eggermann et al., 2014; Jacobs and Fornal, 1993) (Reimer, McGinley, McCormick, Tolias, unpub”

  • Pharmacological block of both cholinergic and noradrenergic receptors locally in the cortex is associated with a strong reduction of the ability of locomotion to modulate cortical state.

    “Pharmacological block of both cholinergic and noradrenergic receptors locally in the cortex is associated with a strong reduction of the ability of locomotion to modulate cortical state (Eggermann et al., 2014; Polack et al., 2013), suggesting that movement may reduce low frequency, and promote higher frequency, rhythms largely through its association with arousal.”

  • The high correlation between movement and basal forebrain cholinergic activity, and neurons in the region of the brainstem cholinergic nuclei, suggests that there may also be a high correlation between pupil diameter and the activity of these neurons.

    “The high correlation between movement and basal forebrain cholinergic activity (Eggermann et al., 2014), and neurons in the region of the brainstem cholinergic nuclei (Lee et al., 2014) suggests that there may also be a high correlation between pupil diameter and the activity of these neurons.”

  • Both basal forebrain cholinergic and locus coeruleus noradrenergic neurons increase their discharge in relation to increased attention to external stimuli, arousal, and locomotion, in both a graded and transient manner.

    “Both basal forebrain cholinergic and locus coeruleus noradrenergic neurons increase their discharge in relation to increased attention to external stimuli, arousal, and locomotion, in both a graded and transient manner (Figure 9) (Aston-Jones and Cohen, 2005; Eggermann et al., 2014; Steriade and McCarley, 2005).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
