Abstract

In light of evidence implicating dopamine in the pathophysiology of attention deficit disorder and schizophrenia, diseases involving attentional or sensory processing abnormalities, it was of interest to determine whether and how dopamine neurons in the ventral tegmental area respond to sensory stimuli. The single-unit responses of ventral tegmental dopamine neurons were recorded in freely-moving cats during the presentation of brief, non-conditioned auditory and visual stimuli. Both auditory and visual stimuli produced neuronal excitation, involving a greater than 5-fold increase in the probability of burst firing followed by a period of burst inhibition. The burst nature of the single-unit response suggests that sensory-induced dopamine release at target sites was disproportionally large relative to the discharge frequency. While characteristics of the dopaminergic sensory response were similar for auditory and visual stimuli, the response latency was longer for visual stimuli. The results demonstrate that dopamine neurons in the ventral tegmental area, the site of origin for mesolimbocortical dopamine neurons, are reliably activated by non-conditioned auditory and visual stimuli.

  • It is unclear how NAc dopamine release encodes the properties and/or emotional valence of arousing visual stimuli, such as visual threats.

    “While many previous studies have reported phasic firing of dopaminergic neurons in response to light flashes in laboratory animals (Horvitz et al., 1997; Comoli et al., 2003; Dommett et al., 2005), it is unclear how NAc dopamine release encodes the properties and/or emotional valence of arousing visual stimuli, such as visual threats.”
  • Recognition of the two-component structure of phasic dopamine responses may resolve earlier controversies that suggested an attentional rather than rewarding role of the dopamine prediction-error signal.

    “Recognition of the two-component structure of phasic dopamine responses may also resolve earlier controversies, which suggested an attentional rather than rewarding role of the dopamine prediction-error signal64,65 on the basis of activations following exposure to physically salient stimuli16,20 and punishers24.”
  • Patients with schizophrenia exhibit abnormally high levels of neural activity to self-generated sensory stimuli.

    “Evidence for this theory has been provided by studies showing that patients with schizophrenia exhibit abnormally high levels of neural activity to self-generated sensory stimuli.[56][57][58][59]”

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.
