Contact-dependent Signaling01:19

Contact-dependent Signaling

40.2K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

Gap Junctions

48.1K
Multicellular organisms employ a variety of ways for cells to communicate with each other. Gap junctions are specialized proteins that form pores between neighboring cells in animals, connecting the cytoplasm between the two, and allowing for the exchange of molecules and ions. They are found in a wide range of invertebrate and vertebrate species, mediate numerous functions including cell differentiation and development, and are associated with numerous human diseases, including cardiac and...

Electrical Synapses

10.1K
Electrical synapses found in all nervous systems play important and unique roles. In these synapses, the presynaptic and postsynaptic membranes are very close together (3.5 nm) and are actually physically connected by channel proteins forming gap junctions.
Gap junctions allow the current to pass directly from one cell to the next. In contrast, in the chemical synapse, the neurotransmitters carry the information through the synaptic cleft from one neuron to the next. They consist of two...

Control Systems: Applications

1.2K
Electrical engineering plays a pivotal role in our daily lives, with control systems at the heart of many applications, from home appliances to sophisticated space shuttles. Control systems manage and regulate the behavior of devices and processes, ensuring they function safely, correctly, and efficiently.
In modern vehicles, control systems manage various functions to enhance performance and safety. The steering wheel and accelerator are primary inputs in a car's control system. The...

State Space Representation01:27

State Space Representation

785
The frequency-domain technique, commonly used in analyzing and designing feedback control systems, is effective for linear, time-invariant systems. However, it falls short when dealing with nonlinear, time-varying, and multiple-input multiple-output systems. The time-domain or state-space approach addresses these limitations by utilizing state variables to construct simultaneous, first-order differential equations, known as state equations, for an nth-order system.
Consider an RLC circuit, a...

Neuronal Communication01:28

Neuronal Communication

5.5K
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...

Área de la Ciencia:

  • Neurociencia
  • Ciencia de Redes
  • Biología Computacional

Sus antecedentes:

  • El cerebro humano exhibe una actividad dinámica continua, transitando entre varios estados cerebrales.
  • La teoría de control de redes ofrece un marco para analizar los costos energéticos de estas transiciones de estado.
  • Los modelos tradicionales asumen entradas de nodos independientes, ignorando la continuidad espacial del cerebro y la especificidad limitada de la estimulación.

Objetivo del estudio:

  • Adaptar los modelos de control de redes para incorporar entradas espacialmente extendidas.
  • Investigar cómo las estrategias de entrada realistas afectan la energía requerida para las transiciones de estado cerebral.
  • Identificar estrategias de control eficientes y sus correlatos neurobiológicos.

Principales métodos:

  • Se adaptaron modelos de control de redes para incluir entradas con influencia que decae exponencialmente con la distancia.
  • Se analizó el impacto de las entradas espacialmente extendidas en los requisitos de energía para las transiciones de estado.
  • Se identificaron estrategias de control casi óptimas y se mapeó la densidad de sitios de entrada.

Principales resultados:

  • Las entradas espacialmente extendidas reducen sustancialmente la energía necesaria para las transiciones de estado cerebral.
  • Las estrategias de control casi óptimas disminuyen significativamente el número de entradas requeridas (hasta dos órdenes de magnitud).
  • Los mapas de densidad de sitios de entrada óptimos se alinean con mapas funcionales, metabólicos, genéticos y neuroquímicos independientes.

Conclusiones:

  • La incorporación de entradas espacialmente extendidas proporciona un marco más realista y energéticamente eficiente para el control cerebral.
  • Este enfoque aprovecha las dependencias espaciales en la conectividad y la actividad cerebral.
  • Los hallazgos ofrecen un método con base neurobiológica para comprender y controlar la dinámica cerebral.
