Neural Circuits01:25

Neural Circuits

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...
Propagation of Action Potentials01:23

Propagation of Action Potentials

The propagation of an action potential refers to the process by which a nerve impulse, or "action potential," travels along a neuron.
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...
Virtual Work for a System of Connected Rigid Bodies01:06

Virtual Work for a System of Connected Rigid Bodies

Virtual work is a powerful method used to solve problems involving several connected rigid bodies. When the system is in equilibrium, virtual work is zero. This allows the calculation of the resulting forces when a system undergoes a virtual displacement. When attempting to analyze such a system, first, use a free-body diagram, where an independent coordinate represents the configuration of the links, and mark its deflected position resulting from the positive virtual displacement.
Next,...
Planar Rigid-Body Motion01:22

Planar Rigid-Body Motion

Understanding the movement of a rigid body in planar motion involves recognizing that every particle within this body is traversing a path that maintains a consistent distance from a specific plane. This concept is fundamental in the study of physics and mechanical engineering, and it allows us to comprehend better how objects move in space.
Planar motion is typically divided into three distinct categories. The first is rectilinear translation, demonstrated by a subway train that moves along...
Plasticity00:58

Plasticity

Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...
Neural Regulation01:37

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.

Area of Science:

  • Cognitive Neuroscience
  • Neuroimaging
  • Visual Perception

Background:

  • Objects are perceived as continuous despite temporary visual obstruction in daily life.
  • Understanding the neural basis of object permanence is crucial for cognitive science.

Purpose of the Study:

  • To investigate the neural mechanisms underlying the perception of continuous objects during dynamic occlusion.
  • To identify brain regions involved in maintaining object representations when visual input is missing.

Main Methods:

  • Functional magnetic resonance imaging (fMRI) was employed.
  • An attentive tracking paradigm was utilized to monitor object perception during occlusion.
  • Brain activity was analyzed during periods of object visibility versus occlusion.

Main Results:

  • Specific cortical regions exhibited heightened activity during object occlusion compared to full visibility.
  • These activated regions are hypothesized to support the active maintenance of an object's spatiotemporal properties.
  • Evidence suggests a neural basis for the continuous perception of occluded objects.

Conclusions:

  • The brain actively fills perceptual gaps to maintain object continuity.
  • Neural substrates identified may underpin the phenomenon of object permanence.
  • Findings contribute to understanding visual tracking and cognitive persistence.
