Motor and Sensory Areas of the Cortex01:14

Motor and Sensory Areas of the Cortex

The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex.
Vision01:24

Vision

Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.
Relative Motion Analysis using Rotating Axes01:25

Relative Motion Analysis using Rotating Axes

Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame.
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it instrumental in...

Curvilinear Motion: Rectangular Components

Curvilinear motion characterizes the movement of a particle or object along a curved path, notably evident when envisioning a car navigating a winding road. If the car starts at point A, its position vector is established within a fixed frame of reference, where the ratio of the position vector to its magnitude signifies the unit vector pointing in the position vector's direction.
As the car advances, its position evolves over time. Quantifying the car's velocity involves computing the time...

Absolute Motion Analysis- General Plane Motion

Visualize a drone, with its propellers spinning rapidly, hovering mid-air. The fascinating movements and operations of this drone can be comprehended by applying the principle of general plane motion.
As the drone's propellers rotate, an upward force is generated that counteracts the force of gravity, enabling the drone to lift off from the ground. This initial movement of the drone is along a straight path, representing a form of translational motion. In this phase, every point on the drone...

Relative Motion Analysis using Rotating Axes-Problem Solving

Consider a crane whose telescopic boom rotates with an angular velocity of 0.04 rad/s and angular acceleration of 0.02 rad/s2. Along with the rotation, the boom also extends linearly with a uniform speed of 5 m/s. The extension of the boom is measured at point D, which is measured with respect to the fixed point C on the other end of the boom. For the given instant, the distance between points C and D is 60 meters.
Here, in order to determine the magnitude of velocity and acceleration for point...

Summary

Infant visual processing of motion develops significantly between 2 and 5 months. Early visual pathways bypass the primary visual cortex in young infants, as shown by electroencephalography (EEG) event-related potentials (ERPs).

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Visual Neuroscience

Background:

  • Cortical processing of visual stimuli is crucial for infant development.
  • Understanding the maturation of visual pathways provides insights into early cognitive abilities.

Purpose of the Study:

  • To investigate the developmental trajectory of cortical visual processing in infants.
  • To examine the electrophysiological responses to a rotating visual pattern across different infant age groups and adults.

Main Methods:

  • High-density electroencephalography (EEG) was employed.
  • Event-related potentials (ERPs) were recorded in response to a rotating visual pattern.
  • Participants included 2-, 3-, and 5-month-old infants and adults.

Main Results:

  • Motion-induced ERPs were observed in the parietal and occipitotemporal (OT) regions at all ages.
  • ERPs were discernible in 2-month-olds, unilateral in 3-month-olds, and bilateral in 5-month-olds and adults.
  • Primary visual cortex (V1) ERPs were absent in 2-month-olds and delayed in 3-month-olds compared to OT regions.

Conclusions:

  • Infant visual processing of motion shows significant developmental changes within the first 5 months of life.
  • Evidence suggests a V1 bypass pathway may supply information to the OT regions in younger infants.
  • Findings align with existing behavioral and psychophysical data on infant visual perception.
