0:05 Orbitofrontal cortex. The orbitofrontal cortex (OFC) is a prefrontal cortex region in the frontal lobes in the brain which is involved in the cognitive processing of decision-making.
In non-human primates it consists of the association cortex areas Brodmann area 11, 12 and 13; in humans it consists of Brodmann area 10, 11 and 47[1] 0:04 Anger. Anger is an emotional response related to one's psychological interpretation of having been threatened.
Often it indicates when one's basic boundaries are violated. Some have a learned tendency to react to anger through retaliation. Anger may be utilized effectively when utilized to set boundaries or escape from dangerous situations. Sheila Videbeck describes anger as a normal emotion that involves a strong uncomfortable and emotional response to a perceived provocation.[1] Raymond Novaco of UC Irvine, who since 1975 has published a plethora of literature on the subject, stratified anger into three modalities: cognitive (appraisals), somatic-affective (tension and agitations), and behavioral (withdrawal and antagonism).[2] William DeFoore, an anger-management writer, described anger as a pressure cooker: we can only apply pressure against our anger for a certain amount of time until it explodes.[3] Psychology and sociology[edit] Rage[edit] Symptoms[edit] Passive anger[edit] Causes[edit]
0:01 The Human Brain - Stress. Chronic over-secretion of stress hormones adversely affects brain function, especially memory.
Too much cortisol can prevent the brain from laying down a new memory, or from accessing already existing memories. The renowned brain researcher, Robert M. Sapolsky, has shown that sustained stress can damage the hippocampus , the part of the limbic brain which is central to learning and memory. The culprits are "glucocorticoids," a class of steroid hormones secreted from the adrenal glands during stress. They are more commonly know as corticosteroids or cortisol . During a perceived threat, the adrenal glands immediately release adrenalin. Topics. 1:37 How the McGurk effect mixes up sights and sounds in the brain. @Death_By_SnuSnu: No, because the lack of 'distinctness' between the two sounds is exactly what causes the effect.
In other words /ba/ and /ga/ and /da/ and /va/ would all be subject to it between themselves, /wo/ and /th/ would not. @Merricat: Haha. Yeah, I meant that as more of a rhetorical question. I DON'T think it would work for that reason. I guess I'm saying it doesn't seem like that remarkable an effect to me because it many languages, it's effectively the same sound anyway. 0:03 The Effect of Sound on the Human Mind. The effects of background white noise on memory performance in inattentive school children. 0:08 The science behind misophonia, and possible treatments « Haunted by everyday noises. NOTE: Much has changes since I wrote this post.
Please see my blog’s home page for updates on what I’ve learned about this condition and the experimental treatments I’m trying. I was poking around on a website that helps link misophonia sufferers to doctors who study the condition, and I found a document on the site that gives a thorough explanation of misophonia and its associated conditions, including phonophobia (fear of sounds). The explanations were so good, I thought I would share them here. For more information, visit the 4S provider network website. According to the document, this is how you pronounce the condition: mis-ō-fō′nē-ă (MISS OH PHONY UH) 0:00 Rare sensitivity triggers undue rage, Hamden audiologist explains.
Misophonia: It's a strange and hidden condition so recently recognized that even most doctors are not aware of it.
Sufferers experience an instant reaction of rage when they hear certain eating, chewing and breathing sounds. A Hamden audiologist, Natan Bauman, is addressing the topic today at the American Academy of Audiology's annual conference in Boston. Bauman, who has also developed hearing aids, will propose an explanation of the neurophysiological mechanism that governs misophonia and review a treatment protocol he's developed. The rare and poorly-understood condition, sometimes called soft sound sensitivity syndrome, or 4S, usually starts in late childhood.
The range of trigger sounds typically expands over time, sometimes including visual triggers, like foot-bobbing. 0:03 Nucleus accumbens. Each brain hemisphere has its own nucleus accumbens.
It is located where the head of the caudate and the anterior portion of the putamen meet just lateral to the septum pellucidum. The nucleus accumbens can be divided into two structures—the nucleus accumbens core and the nucleus accumbens shell. These structures have different morphology and function. Research has indicated the nucleus accumbens has an important role in pleasure including laughter, reward, and reinforcement learning, as well as fear, aggression, impulsivity, addiction, and the placebo effect.[3][4][5][6] Cell types[edit]
0:01 Tinnitus masker. Tinnitus maskers are a range of devices based on simple white noise machines which are used to add natural or artificial sound into a tinnitus sufferer's environment in order to suppress or mask the ringing.
The mechanism of sound masking can be explained by analogy with light. In a dark room where someone is turning a lamp on and off, the light will be obviously noticeable. However if the overhead lights are turned on, turning on the lamp will no longer be as distracting because it has been "masked". Tinnitus maskers increase the level of sound in the listener's environment and therefore mask the ringing in the sufferer's head with a calming, less intrusive sound.
Devices[edit] The concept that an external sound could suppress perception of an internal one was first realised clinically in the mid 1970s by Dr Jack Vernon, when he reported that white noise was effective in alleviating tinnitus. Some sufferers require masking at all times. Habituation[edit] See also[edit] External links[edit]

Back to Table of Contents | November 2011 Hyperacusis and Misophonia The Lesser-Known Siblings of Tinnitus By Paula Schwartz, Au.D., Jason Leyendecker, Au.D., and Megan Conlon ■ Hyperacusis (decreased sound tolerance) and misophonia (fear of sound) are two conditions about which little is known.
Consequently, physicians often struggle when they encounter patients who are affected by them. Hearing loss and tinnitus are the primary hearing-related reasons people seek help from physicians. A Case of Hyperacusis Sue Smith is a professional cellist.
