Resumen
Los monos también son monos.
Área de la Ciencia:
- La neurociencia es la neurociencia.
- Teoría de la decisión Teoría de la decisión.
- Comportamiento de los primates.
Sus antecedentes:
- La teoría de la decisión sugiere que las elecciones se basan en el valor evaluado de las respuestas potenciales.
- El valor de respuesta está influenciado por la probabilidad y magnitud de ganancia esperada.
Objetivo del estudio:
- Para investigar cómo la recompensa esperada influye en la actividad neuronal en el cerebro de los primates.
- Explorar el papel del área intraparietal lateral en la toma de decisiones.
Principales métodos:
- Actividad neuronal registrada en el área intraparietal lateral de monos.
- Los monos realizaron tareas de movimiento ocular con diferentes probabilidades y magnitudes de recompensa.
- Analizó las respuestas neuronales en relación con las ganancias esperadas y las elecciones de animales.
Principales resultados:
- La actividad neuronal en el área intraparietal lateral modulada por la magnitud de la recompensa esperada.
- La actividad neuronal fue sensible a la probabilidad de lograr una ganancia.
- Tanto las elecciones de los monos como la activación neuronal se correlacionaron con las ganancias esperadas relativas.
Conclusiones:
- El área intraparietal lateral juega un papel clave en la integración de la información de recompensa para la selección de la acción.
- La teoría de la decisión proporciona un marco valioso para comprender las bases neuronales de la elección.
- Los hallazgos ofrecen información sobre los mecanismos neuronales que vinculan la percepción a la acción.

Neural Regulation
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
The Spinal Cord
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.
Spinal Cord: Information Processing
The spinal cord is an integral hub for motor and sensory information that enables the brain to communicate with the peripheral nervous system (PNS). This communication consists of relaying sensory data and transmission of motor commands.
Sensory Information Processing
Sensory information processing begins at the sensory receptors located in the skin and other tissues, which detect somatic sensory stimuli such as touch, temperature, or pain. These receptors function as catalysts, initiating...

Neuronal Communication
Neurons, the fundamental units of the brain and nervous system, communicate through complex electrochemical signals that underpin all cognitive and bodily functions. This communication is primarily facilitated by a process involving the generation and propagation of an action potential along the axon of the neuron. When the internal electrical charge of a neuron surpasses a certain threshold, an action potential is triggered. This rapid change in voltage travels swiftly along the axon to the...
Neuroplasticity
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.
Organization of the Brain
The brain is an integral component of the nervous system and serves as the center for processing sensory inputs, making decisions, and directing bodily actions. This complex organ is organized into three primary sections: the hindbrain, midbrain, and forebrain, each responsible for a range of vital functions.
Hindbrain
The hindbrain, located at the base of the brain, plays a vital role in regulating automatic processes that sustain life. It includes the medulla oblongata, which is essential for...
