Motor and Sensory Areas of the Cortex01:14

Motor and Sensory Areas of the Cortex

4.6K
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....

Somatosensory, Motor, and Association Cortex

902
The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...

Association Areas of the Cortex01:21

Association Areas of the Cortex

6.2K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Piaget's Stage 1 of Cognitive Development

772
The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

The Nativist Approach01:21

The Nativist Approach

127
The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to...

Role of Cerebellum and Prefrontal Cortex in Memory01:14

Role of Cerebellum and Prefrontal Cortex in Memory

570
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...

Area of Science:

  • Developmental neuroscience
  • Cognitive psychology
  • Visual perception

Background:

  • Object recognition is vital in infancy, but underlying neurophysiology is unclear.
  • Early visual experience shapes attentional prioritization.
  • Understanding infant brain development is key to cognitive science.

Purpose of the Study:

  • To investigate how training infants on novel objects affects visuocortical responses.
  • To test if object training creates a competitive advantage for processing trained stimuli.
  • To examine age-related changes in visual processing and attentional bias.

Main Methods:

  • Cross-sectional study of 51 infants (6, 9, 12 months) and parents.
  • Infants interacted with novel objects via books.
  • Electroencephalography (EEG) measured steady-state visual evoked potentials (ssVEPs) to trained vs. untrained objects.

Main Results:

  • Visuocortical responses showed age-dependent competition between trained and untrained objects.
  • Responses to trained objects increased, while responses to untrained objects decreased with age.
  • A bias favoring trained objects emerged by 9 months, strengthening at 12 months.

Conclusions:

  • Experience with objects drives selective prioritization of visuocortical resources in infants.
  • Competitive neural interactions support the development of object recognition.
  • Attentional biases are shaped by early object learning in the infant brain.
