Summary
This study proposes a cognitive model for external auditory hallucinations, suggesting they arise from a heightened sensitivity to detect absent sounds, especially in noisy environments. This phenomenon is termed hypervigilance hallucination.
Area of Science:
- Cognitive Psychology
- Clinical Psychiatry
Background:
- Investigates the formation of external auditory hallucinations.
- Integrates cognitive psychology principles and clinical observations.
Observation:
- Focuses on experiences in noisy environments.
- Proposes a model for detecting absent auditory stimuli (false positives).
Findings:
- Highlights cognitive processes leading to false positive detection.
- Suggests false positives are a byproduct of a threat-detection system.
- Introduces the term 'hypervigilance hallucination'.
Implications:
- Discusses the clinical relevance of the proposed model.
- Offers insights into the mechanisms of auditory hallucinations.

01:13The Cochlea
52.4K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

01:26Positive Symptoms Schizophrenia: Hallucinations and Delusions
927
Schizophrenia is a complex psychiatric disorder characterized by a range of symptoms that significantly impact cognition, behavior, and emotional regulation. Among these, the positive symptoms stand out as they involve the addition or exaggeration of normal mental functions, deviating markedly from typical behavior and perception. Hallucinations and delusions are prominent positive symptoms, each profoundly affecting the individual's experience of reality.

01:15Auditory Pathway
8.7K
Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.

13.3K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

01:17Auditory Perception
1.4K
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
