Summary
This review examines disorders of body awareness, including Pathological Embodiment (PE) and related syndromes. It explores common features and differences to understand the neural basis of body representation.
Area of Science:
- Neuropsychology
- Cognitive Neuroscience
Background:
- Disorders of body awareness have been extensively studied.
- Pathological embodiment and disembodiment conditions present unique challenges to understanding body representation.
Purpose of the Study:
- To review neuropsychological evidence of pathological embodiment/disembodiment.
- To describe common and complementary features of these conditions.
- To propose insights into the structure and function of shared body representation.
Main Methods:
- Review of experimental studies on Pathological Embodiment (PE).
- Analysis of complementary syndromes: somatoparaphrenia and xenomelia (Body Integrity Identity Disorders).
- Discussion of behavioral similarities and differences.
Main Results:
- Pathological Embodiment involves patients claiming ownership of another's body part.
- Somatoparaphrenia and xenomelia represent opposite disturbances in body ownership.
- Comparing these conditions reveals shared and distinct characteristics.
Conclusions:
- These disorders offer valuable insights into the neural underpinnings of body representation.
- Understanding pathological embodiment and disembodiment can refine models of body ownership.
- Further research is needed to fully elucidate the shared body representation system.

01:33Somatosensation
42.4K
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.

Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.

01:21Mechanistic Models: Overview of Compartment Models
271
Mechanistic models, a category encompassing both physiological and compartmental modeling, differ from empirical models' approaches to incorporating known factors about the systems being modeled. Empirical models describe data with minimal assumptions, while mechanistic models aim to provide a robust description of available data by specifying assumptions and integrating known factors about the system. Compartmental analysis is a key example of a mechanistic model in pharmacokinetics and...

01:09Clearance Models: Physiological Models
199
Drug clearance is a critical pharmacokinetic process involving the irreversible removal of drugs from the body through various organs over a specified time period. Physiological models are indispensable in determining organ-specific clearance, defined by the proportion of the drug eliminated per unit of time from the organ's blood volume.
The organ's clearance rate depends on the blood flow to the organ and the extraction ratio (E). The extraction ratio describes the organ's...

Physiological and compartmental models are valuable tools used in studying biological systems. These models rely on differential equations to maintain mass balance within the system, ensuring an accurate representation of the dynamic processes at play.
Physiological models take a detailed approach by considering specific molecular processes. They can predict drug distribution, metabolism, and elimination changes, providing a comprehensive understanding of how drugs interact with the body.

01:24Overview of Anatomy and Physiology
31.1K
Human anatomy is the scientific study of the body's structures. Some of these structures are very small and can only be observed and analyzed with the assistance of a microscope. Other larger structures can readily be seen, manipulated, measured, and weighed. The word "anatomy" comes from a Greek root that means "to cut apart." Human anatomy was first studied by observing the body's exterior and the wounds of soldiers and other injuries. Later, physicians were allowed to...
