|October 3, 2014
Summary
This study explores using cerebral cortex capillary changes to determine biological age in humans. These findings could aid in forensic identification by analyzing brain capillaries.
Area of Science:
- Neuroscience
- Histology
- Biochemistry
Context:
- Investigates postnatal human development from 1 month to 83 years.
- Focuses on the cerebral cortex's capillary bed.
- Utilizes histological and histochemical analysis techniques.
Purpose:
- To determine biological age in humans.
- To assess structural and functional changes in brain capillaries.
- To evaluate the utility of capillary analysis for forensic identification.
Summary:
- The study examined capillary beds in the human cerebral cortex across postnatal development.
- Histological and histochemical methods revealed age-related structural and functional capillary alterations.
- These capillary changes in the olfactory brain regions show potential for forensic identification.
Impact:
- Provides a novel method for biological age estimation.
- Offers insights into age-related neurovascular changes.
- Suggests a new tool for forensic medical expertise and personality identification.

4
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this...

01:30Neuron Structure
17.4K
Neurons are the main type of cell in the nervous system that generate and transmit electrochemical signals. They primarily communicate with each other using neurotransmitters at specific junctions called synapses. Neurons come in many shapes that often relate to their function, but most share three main structures: an axon and dendrites that extend out from a cell body.

01:30Cognitive Development During Adulthood
1.4K
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...
