La dependencia física de la morfina no se desarrolla durante el estado de hibernación
Science (New York, N.Y.)
|June 26, 1981
Resumen
Los hibernadores de mamíferos, Citellus lateralis, desarrollan dependencia física de la morfina cuando están activos, pero no durante la hibernación. La exposición a opiáceos durante la hibernación muestra una respuesta parcial del sistema nervioso central.
Área de la Ciencia:
- La neurociencia es la neurociencia.
- Farmacología Farmacología.
- La hibernación de los mamíferos
Sus antecedentes:
- La dependencia física de los opioides es una preocupación clínica significativa.
- La hibernación de los mamíferos representa un estado fisiológico único con funciones metabólicas y neurológicas alteradas.
- Comprender las interacciones opioides durante la hibernación es crucial para las posibles aplicaciones terapéuticas.
Objetivo del estudio:
- Para investigar el desarrollo de la dependencia física de la morfina en el hibernador de mamíferos, Citellus lateralis.
- Para determinar si la exposición a la morfina durante la hibernación afecta el desarrollo de la dependencia física.
- Para evaluar la capacidad de respuesta del sistema nervioso central a los opioides durante el estado de hibernación.
Principales métodos:
- Administración de morfina a Citellus lateralis. activo y en hibernación.
- Evaluación de la dependencia física utilizando criterios farmacológicos estándar.
- Observación de las respuestas conductuales a la morfina durante la hibernación.
Principales resultados:
- La dependencia física de la morfina se desarrolló típicamente en Citellus lateralis. activo.
- No se observó dependencia física de la morfina cuando la exposición se limitó al estado de hibernación.
- La administración de morfina durante la hibernación indujo comportamientos estereotipados, lo que indica una respuesta parcial al opioide del sistema nervioso central.
Conclusiones:
- El estado de hibernación en Citellus lateralis previene el desarrollo típico de la dependencia física de la morfina.
- El sistema nervioso central conserva una respuesta parcial a los opioides durante la hibernación.
- La hibernación altera significativamente la farmacodinámica de los opiáceos y la responsabilidad de la dependencia.

01:24Sleep-Wake Cycles
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

01:18Metabolic States of the Body: The Postabsorptive State
The postabsorptive state usually starts about four hours after a meal and lasts until the next meal is eaten. During this time, the digestive system stops absorbing nutrients, and the body uses stored energy reserves to maintain stable blood glucose levels.
Initially, glycogen stored in the liver is broken down to release glucose into the bloodstream, while glycogen in the muscles is broken down to supply glucose for energy directly within the muscle cells. As glycogen stores diminish,...

01:24Metabolic States of the Body: Fasting and Starvation
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...
01:15Subconsciousness and No Awareness
The concept of subconscious awareness refers to the processing of information below the level of conscious thought, which significantly influences both behaviors and decisions. It is also known as waking subconscious awareness. This complex level of cognition operates without the direct awareness of the individual, facilitating rapid and simultaneous handling of multiple information streams.

01:13Insufficient Sleep and Sleep Deprivation
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

01:22Stages of Sleep
Sleep progresses through distinct stages, each characterized by specific brain wave patterns and physiological responses ranging from wakefulness to stages of non-rapid eye movement, known as non-REM, to rapid eye movement, referred to as REM. Understanding these stages helps in recognizing how sleep supports various bodily and cognitive functions.
Before sleep begins, in wakefulness, the brain exhibits primarily beta waves, which are high in frequency and low in amplitude, indicating alertness...
