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...

Collisions in Multiple Dimensions: Problem Solving

5.6K
In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.
A small car of mass 1,200 kg traveling east at 60 km/h collides at an intersection with a truck of mass 3,000 kg traveling due north at 40 km/h. The two vehicles are locked together. What is the...

Parallel Processing

809
The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...

Multi-input and Multi-variable systems

Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.
In the absence of...

Collisions in Multiple Dimensions: Introduction

7.1K
It is far more common for collisions to occur in two dimensions; that is, the initial velocity vectors are neither parallel nor antiparallel to each other. Let's see what complications arise from this. The first idea is that momentum is a vector. Like all vectors, it can be expressed as a sum of perpendicular components (usually, though not always, an x-component and a y-component, and a z-component if necessary). Thus, when the statement of conservation of momentum is written for a...

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.

Sus antecedentes:

  • El conflicto cognitivo es común, pero su base neuronal es debatida.
  • Las teorías incluyen mecanismos de dominio general, módulos específicos o mecanismos superpuestos.

Objetivo del estudio:

  • Investigar los mecanismos neuronales del procesamiento de conflictos cognitivos.
  • Diferenciar entre modelos de dominio general, específicos de tarea y superpuestos.

Principales métodos:

  • Se analizaron datos de electroencefalograma (EEG) de 507 adultos sanos.
  • Se utilizó decodificación multivariante para identificar la actividad neuronal relacionada con el conflicto.
  • Se emplearon tres tareas de conflicto distintas: Detección de Cambios, Simon y Stroop.

Principales resultados:

  • Se observó una decodificación robusta del conflicto dentro de cada tarea.
  • La decodificación entre tareas reveló representaciones compartidas solo entre pares de tareas específicos.
