The ventrolateral orbital cortex (VLO) is part of an endogenous analgesic system, consisting of the spinal cord-thalamic nucleus submedius-VLO periaqueductal gray (PAG)-spinal cord loop. The present study examined morphological connections of GABAergic (gamma-aminobutyric acidergic) neurons and serotonergic projection terminals from the dorsal raphe nucleus (DR), as well as the relationship between GABAergic terminals and VLO neurons projecting to the PAG, by using anterograde and retrograde… 

Structural basis for serotonergic regulation of neural circuits in the mouse olfactory bulb

The present study strongly implicates the involvement of brain regions such as the DRN in regulation of the elaborate mechanisms of olfactory processing and provides a structure basis of the network for coordinating or linkingOlfactory encoding with other neural systems, with special attention to serotonergic regulation.

“Subpial Fan Cell” — A Class of Calretinin Neuron in Layer 1 of Adult Monkey Prefrontal Cortex

The distribution and connectivity of SPF cells suggest they act as integrative hubs in upper layer 1 during postnatal maturation, and likely provides a transminicolumnar excitatory influence across swathes of apical dendritic tufts — thus affecting information processing in discrete patches of layer 1 in adult monkey PFC.

Descending Modulation of Laryngeal Vagal Sensory Processing in the Brainstem Orchestrated by the Submedius Thalamic Nucleus

A novel and functionally relevant example of intersection between vagal and somatosensory processing in the brain is demonstrated, suggesting an intersection betweenvagal sensory pathways and the endogenous analgesia system, potentially important for understanding vagal sensory processing in health and mechanisms of hypersensitivity in disease.

GABAergic neurons express μ-opioid receptors in the ventrolateral orbital cortex of the rat

The afferent and efferent connections of the nucleus submedius in the rat

The afferent and efferent connections of the nucleus submedius (Sm) in the medial thalamus of the rat were examined and retrogradely labeled neurons were observed primarily in the deep layers of VLO and the dorsal peduncular cortex.

Trigeminal projections to the nucleus submedius of the thalamus in the rat

Results suggest that the Sm of the rat receives its orofacial afferent inputs from brainstem neurons that are localized to the caudal interpolaris and rostral caudalis in the central processing of pain.

Expression of serotonin1A and serotonin2A receptors in pyramidal and GABAergic neurons of the rat prefrontal cortex.

The role of 5-HT in prefrontal circuits is clarified and new light is shed to the cellular elements involved in the action of atypical antipsychotic drugs.

Retrograde tracing of projections between the nucleus submedius, the ventrolateral orbital cortex, and the midbrain in the rat

Findings suggest that the nucleus submedius might be part of a neural circuit involved in the activation of endogenous analgesia, and that regions within the ventrolateral periaqueductal gray and raphe nuclei project to the Ventrolateral orbital cortex.

Immunocytochemical localization of serotonin1A receptors in the rat central nervous system

The highest density of immunostaining was found in limbic areas (lateral septum, CA1 area of Ammon's horn and dentate gyrus in the hippocampus, and frontal and entorhinal cortices), in agreement with previous autoradiographic studies with selective radioligands showing the enrichment of these regions in serotonin1A receptor binding sites.

Presynaptic serotonergic inhibition of GABAergic synaptic transmission in mechanically dissociated rat basolateral amygdala neurons

5‐HT inhibits GABAergic mIPSCs by inactivating the AC‐cAMP signal transduction pathway via a G‐protein‐coupled 5‐HT1A receptor and this intracellular pathway directly acts on the GABA‐releasing process independent of K+ and Ca2+ channels in the presynaptic nerve terminals.
