Not everyone who experiences tinnitus is significantly bothered by it. [6] However, some experience annoyance, anxiety, panic, loss of sleep, or difficulty concentrating. [2] The distress of tinnitus is strongly associated [vague] with various psychological factors; the loudness, duration, and other characteristics of the tinnitus symptoms are ...
Evaluation of tinnitus can include a hearing test (audiogram), measurement of acoustic parameters of the tinnitus like pitch and loudness, and psychological assessment of comorbid conditions like depression, anxiety, and stress that are associated with severity of the tinnitus.
Symptoms may include a sense of fullness in the ear, tinnitus, and dizziness. [7] [8] The model details how symptoms may be initiated by tensor tympani muscle damage or overload due to acoustic shock or trauma. Hypercontraction or hyperactivity of the muscle may cause an "ATP energy crisis." The muscle is then forced to create energy without ...
Botulism is very rare in dogs and usually follows feeding on carrion. [5] Symptoms include weakness, difficulty eating, acute facial nerve paralysis, and megaesophagus. Compared to other species, dogs and cats are relatively resistant to botulism. [6] Dancing Doberman disease primarily affects the gastrocnemius muscle in Dobermans.
Neurophysiology is a branch of physiology and neuroscience concerned with the functions of the nervous system and their mechanisms. The term neurophysiology originates from the Greek word νεῦρον ("nerve") and physiology (which is, in turn, derived from the Greek φύσις, meaning "nature", and -λογία, meaning "knowledge"). [1]
Tinnitus is described as hearing a sound when an external sound is not present. [13] Noise-induced hearing loss can cause high-pitched tinnitus. [14] An estimated 50 million Americans have some degree of tinnitus in one or both ears; 16 million of them have symptoms serious enough for them to see a doctor or hearing specialist.
Symptoms include liver and kidney failure and vasculitis. [10] Lyme disease* is a disease caused by Borrelia burgdorferi, a spirochaete, and spread by ticks of the genus Ixodes. Symptoms in dogs include acute arthritis, anorexia and lethargy. There is no rash as is typically seen in humans. [11]
The theta model, or Ermentrout–Kopell canonical Type I model, is mathematically equivalent to the quadratic integrate-and-fire model which in turn is an approximation to the exponential integrate-and-fire model and the Hodgkin-Huxley model. It is called a canonical model because it is one of the generic models for constant input close to the ...
