Sensory Perception: Organization of the Somatosensory System01:11

Sensory Perception: Organization of the Somatosensory System

12.5K
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...

Somatosensation01:33

Somatosensation

45.6K
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.

Spinal Cord: Information Processing01:10

Spinal Cord: Information Processing

4.3K
The spinal cord is an integral hub for motor and sensory information that enables the brain to communicate with the peripheral nervous system (PNS). This communication consists of relaying sensory data and transmission of motor commands.
Sensory Information Processing
Sensory information processing begins at the sensory receptors located in the skin and other tissues, which detect somatic sensory stimuli such as touch, temperature, or pain. These receptors function as catalysts, initiating...

Nociception01:44

Nociception

34.8K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Parasympathetic Signaling01:30

Parasympathetic Signaling

4.1K
Parasympathetic signaling plays a crucial role in regulating various physiological processes. It involves the release of acetylcholine (ACh) by parasympathetic neurons, which can have localized and short-lived effects. The majority of ACh released is rapidly inactivated at the synapse by the enzyme acetylcholinesterase (AChE), which hydrolyzes Ach into choline and acetate. Additionally, the tissue cholinesterase deactivates any ACh diffusing into the surrounding tissues.

What is a Sensory System?01:31

What is a Sensory System?

102.9K
Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position.

Area of Science:

  • Neuroscience
  • Psychology
  • Psychophysiology

Background:

  • The body-mind interaction is a complex field with ongoing debate on how physiological arousal influences mental states.
  • Autonomically-mediated physiological arousal is recognized in emotional, social, and motivational behaviors, but mechanisms remain unclear.

Purpose of the Study:

  • To investigate how feedback from autonomic arousal states shapes human cognition and emotion.
  • To explore the role of visceral afferent signals in body-mind interaction.

Main Methods:

  • Utilizing neuroimaging techniques to correlate autonomic changes with neural activity.
  • Examining central consequences of clinical autonomic perturbations.
  • Probing the integration of peripheral autonomic state fluctuations with cognitive and emotional processes.
  • Exploiting arterial baroreceptor signals to study their contribution to emotional stimuli processing.

Main Results:

  • Autonomic arousal influences cognition and emotion through visceral afferent signals.
  • Arterial baroreceptor activation differentially affects emotional stimuli processing.
  • Facilitation of fear and threat processing observed, contrasting with inhibition of pain processing.

Conclusions:

  • Visceral afferent signals, particularly from arterial baroreceptors, play a crucial role in shaping emotional and cognitive processing.
  • Understanding the body-brain-mind axis offers insights into mental health and behavior.
