Neural Circuits01:25

Neural Circuits

3.0K
Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

The Role of Ion Channels in Neuronal Computation

4.0K
A postsynaptic neuron usually receives numerous impulses from several other presynaptic neurons. The axon hillock of the postsynaptic neuron integrates all these signals and determines the likelihood of firing an action potential.
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....

Fusion of Secretory Vesicles with the Plasma Membrane01:26

Fusion of Secretory Vesicles with the Plasma Membrane

19.1K
Proteins and neurotransmitters in secretory vesicles can be released from a cell upon vesicle docking, priming, and fusion with the plasma membrane. Vesicles are docked and primed in preparation for the quick exocytosis of their contents in response to a stimulus. The fusion process is mainly carried out by a SNAP Receptor or SNARE complex, consisting of synaptobrevin, syntaxin-1, and SNAP-25.
In 1993, Jim Rothman proposed that the antiparallel pairing of vesicular and transmembrane SNAREs, or...

Functional Brain Systems: Limbic System01:15

Functional Brain Systems: Limbic System

8.1K
The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

Diencephalon: Anatomical Regions

6.0K
The diencephalon, etymologically translated as 'through brain,' plays an integral role as the conduit between the cerebrum and the vast extent of the nervous system. However, the olfactory system is an exception, as it interfaces directly with the cerebrum. The diencephalon, deeply ensconced beneath the cerebrum, primarily consists of three paired structures — the thalamus, hypothalamus, and epithelamus. It also includes accessory structures such as the subthalamus, which houses the...

Overview of Secretory Vesicles01:33

Overview of Secretory Vesicles

9.7K
Secretory vesicles, also known as dense core vesicles (DCVs), are membrane-bound vesicles that transport secretory proteins, such as hormones or neurotransmitters. Regulated secretory vesicles transport proteins from the trans-Golgi network to the exterior of the cell. Proteins present in regulated secretory vesicles are required to be rapidly exocytosed in large amounts upon a specific stimulus.
Various proteins regulate the aggregation of molecules inside the secretory vesicles. Chromogranins...

  • Neurociencia Cognitiva

Sus antecedentes:

  • El subiculum es una región hipocampal clave interconectada con regiones talámicas, corticales y otras subregiones hipocampales.
  • Estas regiones interconectadas forman una red vital para la cognición espacial, el aprendizaje y la memoria.

Objetivo del estudio:

  • Revisar y reconceptualizar el papel del subiculum dentro de la red hipocampal.
  • Explorar cómo las aferencias subiculares contribuyen a la diversa sintonización espacial y direccional.

Principales métodos:

  • Revisión de literatura de descubrimientos recientes en la circuitería y dinámica neuronal del subiculum.
  • Análisis de las conexiones aferentes al subiculum desde el hipocampo, el tálamo y las cortezas.
  • Discusión de las conexiones "no canónicas" y sus implicaciones.

Principales resultados:

  • El subiculum actúa como un sitio de integración, recibiendo y redistribuyendo salidas de múltiples regiones cerebrales.
  • La diversa sintonización espacial y direccional en el subiculum (ubicación, límites, eje de viaje, orientación de la cabeza) se explica por sus conexiones aferentes.
  • Las conexiones no canónicas sugieren roles adicionales en el refinamiento del procesamiento hipocampal.

Conclusiones:

  • El papel del subiculum se extiende más allá de ser una simple región de salida; es un centro de integración crítico.
  • Se justifica una reconceptualización de la función del subiculum en la cognición espacial y la memoria.
  • La comprensión de la integración subicular es clave para comprender las funciones de las redes talámicas, corticales e hipocampales.
