Hypothalamus

The hypothalamus is a small brain region that coordinates homeostasis by linking the nervous and endocrine systems, making it essential for maintaining stable internal conditions. It receives neural and hormonal signals about variables such as body temperature, energy balance, fluid status, and stress, then regulates autonomic responses and pituitary hormone release to adjust organ function. Clinically, hypothalamic dysfunction can disrupt appetite, sleep, thirst, reproduction, growth, and temperature control, while lesions or tumors may affect endocrine regulation and behavior. Understanding these pathways supports the diagnosis and treatment of disorders involving hormonal imbalance, obesity, diabetes insipidus, and stress-related conditions.

2013

Despite the functional and medical importance of the hypothalamus, in utero genetic manipulation of its development has rarely been attempted. We show a detailed procedure for in utero electroporation into the mouse hypothalamus and show representative results of total and partial (regional) hypothalamic transfection.

The hypothalamus is a small yet highly complex and essential brain region that plays a crucial role in regulating various bodily functions. Anatomically, it is located at the base of the brain, just above the brainstem and below the thalamus, forming part of the limbic system. The hypothalamus interacts with other brain regions, including the pituitary gland, through a direct physical connection called the hypothalamic-pituitary axis. The hypothalamus receives somatic and visceral inputs and...

This protocol describes in detail how to specifically transfect different regions in the C57BL/6 central nervous system via in utero electroporation. Included in this protocol are detailed instructions for transfections of regions that develop into the cortex, hippocampus, thalamus, hypothalamus, lateral septal nucleus and striatum.

The activity of single neurons from adult-aged mice can be studied by dissociating neurons from specific brain regions and using fluorescent membrane potential dye imaging. By testing responses to changes in glucose, this technique can be used to study the glucose sensitivity of adult ventromedial hypothalamic neurons.

The function of adult-born mammalian neurons remains an active area of investigation. Ionizing radiation inhibits the birth of new neurons. Using computer tomography-guided focal irradiation (CFIR), three-dimensional anatomical targeting of specific neural progenitor populations can now be used to assess the functional role of adult neurogenesis.
