Genetic and non-genetic determinants of aggression in combat sports
Human aggression/impulsivity-related traits are influenced by complex genetic and non-genetic factors. The aggression/anxiety relationship is controlled by highly conserved brain regions including the amygdala, hypothalamus and periaqueductal gray of the

A Molecularly Defined Midbrain Circuit Mechanism for Sound‐Driven Defensive Behavior and Anxiety
Schematic diagram showing the Cbln2+ ICx–dPAG circuit for sound‐driven defensive and anxiety‐like behaviors. ABSTRACT The innate defense behaviors in response to threatening sounds play a fundamental role in survival. However, the neural circuits that detect threat‐relevant auditory cues and transform them into defensive behaviors remain poorly defined.

Interactions between the lateral hypothalamus and the periaqueductal gray [PDF]
Anatomical and physiological experiments were conducted to characterize the interactions between the lateral hypothalamus (LH) and the periaqueductal gray (PAG) and to determine the role of neurotensin in their interaction. Anatomical studies using injection of Phaseolus vulgaris leucoagglutinin into the LH showed an extensive projection to the ...

Sexual behavior is suppressed by various types of stressors. We previously demonstrated that an alarm pheromone released by stressed male Wistar rats is a stressor to other rats, increases the number of mounts needed for ejaculation, and decreases the ...

Functional organization of the midbrain periaqueductal gray for regulating aversive memory formation
Innately aversive experiences produce rapid defensive responses and powerful emotional memories. The midbrain periaqueductal gray (PAG) drives defensive behaviors through projections to brainstem motor control centers, but the PAG has also been ...

RCI is associated with functional suppression of oxytocinergic neurons in the PVN. Reduced PVNOXT neuronal activity contributes to altered sympathetic regulation involving the IML–sympathetic chain pathway, accompanied by changes in norepinephrine signaling at the BTI.

Enkephalinergic Neurons in the Periaqueductal Gray and Morphine Withdrawal
The effects of opioid (e.g., morphine) withdrawal on levels of endogenous opioid peptides and their mRNA in the various brain regions have been studied. However, the role of this opioidergic mechanism in the mediation of opioid withdrawal is not fully understood.

ABSTRACT Dengue virus (DENV) poses a serious global health challenge, particularly in cases of dengue hemorrhagic fever (DHF). Patients with preexisting mitochondrial disorders may be at increased risk for complications due to the specific impact of DENV on mitochondrial‐dependent cellular processes and immune function.

Cell type-specific modulation of sensory and affective components of itch in the periaqueductal gray
The supraspinal mechanisms involved in itch specific sensation are not well understood. Here the authors identify a subpopulation of neurons in the periaqueductal gray that modulate chronic itch in ...

COX14 Variants Are Associated With Mitochondrial Complex IV Deficiency Nuclear Type 10 (MC4DN10)
ABSTRACT COX14 encodes a transmembrane protein essential for cytochrome c oxidase (COX) complex assembly. A homozygous missense variant in COX14 was reported in three siblings from a single consanguineous family with severe, fatal infantile mitochondrial complex IV deficiency nuclear type 10 (MC4DN10; MIM# 619053).
