|November 10, 1961
Summary
Researchers developed a new probe for creating reversible brain lesions. Cooling the third nerve nucleus in cats caused temporary pupil dilation, demonstrating the probe
Area of Science:
- Neuroscience
- Surgical Technology
Background:
- Accurate lesion creation in the central nervous system is crucial for research.
- Reversible methods offer advantages for studying neural function dynamics.
Purpose of the Study:
- To describe a novel slender refrigeration probe for creating reversible lesions.
- To evaluate the probe's efficacy in a feline model.
Main Methods:
- A slender refrigeration probe was designed and utilized.
- The probe was applied to the third nerve nucleus region in cats.
- Temperature changes and pupillary response were monitored.
Main Results:
- The probe successfully produced discrete, reversible lesions.
- Cooling the third nerve nucleus induced pupillary dilatation.
- The pupillary response was rapidly reversible upon temperature normalization.
Conclusions:
- The refrigeration probe is effective for reversible lesion production in the central nervous system.
- This method allows for dynamic study of neural pathway functions, such as pupillary control.

01:05Long-term Depression
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.
01:43Thermosensation
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

01:29Decreased Body Temperature
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
01:23Diencephalon: Hypothalamus and Coordination
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...

01:26Thermoregulation
The human body has a sophisticated thermoregulation system that employs negative feedback mechanisms to maintain an optimal core temperature. When the core temperature drops, peripheral and central thermoreceptors send signals to the hypothalamus, activating the heat-promoting center. This center triggers several responses aimed at increasing the core temperature. First, vasoconstriction reduces the flow of warm blood from internal organs to the skin so that the heat is not lost from the skin,...
