Sex Stratified Neuronal Cultures to Study Ischemic Cell Death Pathways
Published on: December 9, 2013
Summary
The brain develops as female unless exposed to gonadal hormones during a critical developmental period. This hormonal exposure, even after birth in some animals, shapes neural pathways for pituitary activity and sexual behavior in the hypothalamus.
Area of Science:
- Neuroendocrinology
- Developmental Neuroscience
- Behavioral Neuroscience
Background:
- The brain's developmental trajectory is influenced by hormonal signaling.
- Understanding sex differences in the brain is crucial for reproductive health.
Purpose of the Study:
- To investigate the role of gonadal hormones in brain development and sexual differentiation.
- To identify the specific brain regions involved in hormone-mediated neural development.
Main Methods:
- Studies were conducted on animals with post-natal hormonal exposure.
- Focused on the differentiation of neural substrates regulating pituitary activity and sexual behavior.
Main Results:
- The brain's default developmental state is female.
- Gonadal hormone exposure at critical stages is necessary for sex-specific brain differentiation.
- Specific hypothalamic regions are implicated in this process.
Conclusions:
- Hormonal influences during development are critical for establishing sex-specific neural circuits.
- The hypothalamus plays a key role in mediating the effects of gonadal hormones on behavior and pituitary function.

02:19The Y Chromosome Determines Maleness
The Y chromosome is a sex chromosome found in several vertebrates and mammals, including humans. In addition to 22 pairs of autosomes, the human males have one X chromosome and one Y chromosome. In these organisms, the presence or absence of the Y chromosome determines the development of male traits.
Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size. Today,...

01:20Anatomy of the Brain: Major Regions
The brain is the most complex organ in the human body. It consists of four main parts: the cerebrum, diencephalon, cerebellum, and brainstem.
The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect various areas...

01:18Anatomy of the Brain: Ventricles
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
01:15Development of the Sexual Organs in the Embryo and Fetus
Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the male...

01:05Cerebral Hemispheres
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...
01:28Lateralization
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.
