Serotonergic retinopetal projections from the dorsal raphe nucleus in the mouse demonstrated by combined [(3)H] 5-HT retrograde tracing and immunolabeling of endogenous 5-HT.

, 2000
The present study demonstrated a direct serotonergic retinopetal projection in the mouse stemming from the lateral portion of the dorsal raphe nucleus bilaterally.

Reward probability and timing uncertainty alter the effect of dorsal raphe serotonin neurons on patience

Nature Communications, 2018
Activation of serotonin neurons in the dorsal raphe nucleus promotes patience in waiting for future rewards. Here the authors show that this effect is maximal for high probability reward or high temporal reward uncertainty suggesting that it boosts the ...

Real‐Time Neurochemical Sensing in Zebrafish: Electrochemical and Fluorescent Approaches

Analysis &Sensing, Volume 6, Issue 6, November 2026.
The use of zebrafish has emerged as a powerful approach for real‐time neurochemical measurements. This review highlights recent advances in electrochemical and fluorescent sensing strategies that enable dynamic measurements in live preparations of this complex vertebrate. These complementary approaches provide new insights into neurochemical signaling,

Pressor response to electrical and chemical stimulation of nucleus raphe dorsalis in the cat.

, 1985
The dorsal raphe nucleus was stimulated electrically and chemically in 57 cats with blood pressure being measured by an arterial catheter. Blood pressure rose by a mean of 119.5 +/- 8.9% on stimulation of the dorsal raphe nucleus at a frequency of 200 ...

Distinct Long‐Range Inhibitory and Excitatory Projections From the Mouse Superior Colliculus

Journal of Comparative Neurology, Volume 534, Issue 11, November 2026.
Transgenic mouse lines facilitated viral tracing of superior colliculus inhibitory (vGAT+; orange) and excitatory (vGlut2+; blue) neuronal projections throughout the brain. Example efferent targets are shown for diencephalon and midbrain coronal sections.

Increased electrical and metabolic activity in the dorsal raphe nucleus of Parkinsonian rats.

, 2008
Serotonin (5-HT) containing neurons in the dorsal raphe nucleus (DRN) may play important roles in Parkinson's disease (PD). This study investigated neural and metabolic activity of the DRN in animal PD models based on dopamine depletion.

THE CHANGES OF OPIATE RECEPTOR BINDING IN RAT BRAIN UNDER ELECTROACUPUNCTURE TOLERANCE CONDITION

针刺研究, 1987
The changes of opiate receptor binding under electroacupuncture tolerance were studied in rat brain by autoradiography. Comparing with the results of electroacupuncture analgesia,the opiate re- ceptor binding was reduced significantly in rat brain after ...

In vivo serotonin 1A receptor distribution in treatment-resistant depression

Translational Psychiatry
Major depressive disorder (MDD) ranks among the leading causes of disability worldwide. An additional burden arises from treatment-resistance, defined by a lack of response to two or more adequate pharmacotherapeutic treatment trials.

tDCS cranial nerve Co-stimulation: Unveiling brainstem pathways involved in trigeminal nerve direct current stimulation in rats

Brain Stimulation
Background: The effects of transcranial direct current stimulation (tDCS) are generally thought to result from the polarization of cortical neurons by the weak electric fields it creates.

Influence of early stress on social abilities and serotonergic functions across generations in mice.

PLoS ONE, 2011
Exposure to adverse environments during early development is a known risk factor for several psychiatric conditions including antisocial behavior and personality disorders.
