Summary
Adolescent resilience is linked to stronger brain connections between the prefrontal cortex and hippocampus. These structural and molecular adaptations in brain circuits may help manage traumatic memories and promote well-being.
Area of Science:
- Neuroscience
- Developmental Psychology
- Brain Imaging
Background:
- Prefrontal-hippocampal pathways are crucial for memory suppression and adaptive responses to trauma.
- The role of these circuits in adolescent resilience is not well understood.
Purpose of the Study:
- To investigate the relationship between structural similarity in prefrontal-hippocampal networks and resilience in adolescents.
- To identify molecular adaptations associated with resilience within these circuits.
Main Methods:
- Structural similarity analysis of MRI-based gray matter volume (GMV) was used to map hippocampal connectivity networks.
- Spatial correlation analyses were performed between resilience-related networks and neurotransmitter distribution maps.
Main Results:
- Higher resilience correlated with stronger structural similarity between prefrontal regions (middle frontal gyrus, orbitofrontal cortex) and the hippocampus.
- The serotonergic neurotransmitter system was associated with resilience, modulating prefrontal-hippocampal pathways.
Conclusions:
- Structural and molecular adaptations in prefrontal-hippocampal circuits, involved in memory suppression, may promote resilience in adolescents.
- Findings highlight neurobiological markers for resilience, informing potential therapeutic interventions.

01:06Multipotency and Niche of Bulge Stem Cell
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...
01:16Accessory Structures of the Skin: Hair and Hair Follicles
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

01:20Accessory Structures of the Skin: Hair Growth and Types
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...
01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:12The Hyoid Bone
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...
01:27Signs of Puberty
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...
