Somatosensation01:33

Somatosensation

42.8K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Working Memory01:24

Working Memory

729
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Sensory Perception: Organization of the Somatosensory System

10.9K
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...

Chunking and Rehearsal in Sensory Memory

513
Improving short-term memory can be achieved through techniques like chunking and rehearsal. Chunking involves organizing information into larger, more manageable units. This technique is particularly useful for information that exceeds the typical memory span of between five and nine items. For instance, logging into an online account with a password like "ta89vq0179gz" involves grouping letters and numbers into three chunks—ta89, vq01, and 79gz. It makes large amounts of...

Area of Science:

  • Cognitive Neuroscience
  • Neuroimaging

Background:

  • The approximate number system (ANS) processes numerical estimations, similar to continuous magnitudes.
  • The ANS involves a right-lateralized frontoparietal network, including the lateral prefrontal cortex (LPFC) and intraparietal sulcus.
  • Mechanisms of working memory (WM) for estimated numerosities remain unclear.

Purpose of the Study:

  • Investigate brain regions responsible for retaining approximate numerosity information in working memory.
  • Clarify the neural basis of abstract quantity working memory.

Main Methods:

  • Functional magnetic resonance imaging (fMRI) with multivariate pattern analysis.
  • A delayed match-to-numerosity task was employed.

Main Results:

  • Numerosity-specific working memory representations were identified in the right LPFC.
  • Additional representations were found in the supplementary motor area and left premotor cortex, extending into the superior frontal gyrus.

Conclusions:

  • The right LPFC plays a key role in maintaining estimated numerosities in working memory.
  • These findings contribute to understanding the neural basis of abstract quantity working memory, bridging existing literature gaps.
