Sensory Modalities

Sensory Modalities

Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

Introduction to Special Senses

Introduction to Special Senses

Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive functions.

Generalization, Discrimination, and Extinction

Generalization, Discrimination, and Extinction

Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

Sensory Perception: Organization of the Somatosensory System

Sensory Perception: Organization of the Somatosensory System

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 stimulus...

Synesthesia

Synesthesia

Synesthesia is a remarkable condition where stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. People with synesthesia experience a blending or crossing of their senses, such as sight and sound, leading to cross-modal sensations. In this condition, the stimulation of one sense, such as hearing a number or musical note, triggers an experience of another sense, like sensing a specific color, taste, or smell. People...

Neuroplasticity

Neuroplasticity

Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Summary

Neglect, a disorder of conscious awareness, can affect multiple senses, not just vision. Examining neglect across all sensory modalities offers deeper insights into its mechanisms and potential rehabilitation.

Area of Science:

Neuroscience
Cognitive Science
Psychology

Background:

Human conscious awareness is a key area of research.
Neglect is a striking disorder characterized by an acquired lack of conscious experience of space.
Neglect syndromes often result from unilateral brain damage, impacting conscious stimulus perception despite intact primary sensory areas.

Purpose of the Study:

To investigate the phenomenon of neglect across various sensory modalities.
To advocate for a comprehensive perspective on neglect that includes parallel examination of all sensory modalities.
To explore the implications of multi-sensory neglect for understanding conscious awareness.

Main Methods:

A critical review of existing literature on neglect within and across sensory modalities.
Analysis of studies investigating neglect in tactile, auditory, and chemical senses.
Examination of research on extinction and its relationship to neglect.

Main Results:

Neglect manifestations are observed in tactile, auditory, and chemical senses, occurring individually or concurrently.
Extinction, a related deficit, demonstrates significant interactions between sensory modalities in conscious perception and spatial representation.
Evidence supports the widespread nature of neglect across different sensory systems.

Conclusions:

A parallel examination of neglect and extinction across all sensory modalities enhances comprehension of neglect syndrome mechanisms.
Considering multi-sensory evidence may lead to more effective, multi-sensory based rehabilitation approaches for neglect.
Understanding neglect beyond the visual domain is crucial for a complete picture of conscious awareness.
