One physiological characteristic of sleep goes by the name of "homeostatic regulation". This is the notion that animals need a more or less constant amount of sleep every day, so that if a subject is deprived of sleep one day, the amount of sleep tends to "rebound" (increase) the next few days. This has been observed in zebrafish. At night ...
Catathrenia or nocturnal groaning is a sleep-related breathing disorder, consisting of end-inspiratory apnea (breath holding) and expiratory groaning during sleep.It describes a rare condition characterized by monotonous, irregular groans while sleeping. [1]
Sleep can follow a physiological or behavioral definition. In the physiological sense, sleep is a state characterized by reversible unconsciousness, special brainwave patterns, sporadic eye movement, loss of muscle tone (possibly with some exceptions; see below regarding the sleep of birds and of aquatic mammals), and a compensatory increase following deprivation of the state, this last known ...
The aquatic equivalent to smelling in air is tasting in water. Many larger catfish have chemoreceptors across their entire bodies, which means they "taste" anything they touch and "smell" any chemicals in the water. "In catfish, gustation plays a primary role in the orientation and location of food". [14] Salmon have a strong sense of smell.
Sleep is a normal physiological process, but it sometimes requires work to make it truly restorative, notes Dr. Haq. Pay attention to your body, exercise regularly, eat healthy foods and see your ...
Annoyance effects of noise are minimally affected by demographics, but fear of the noise source and sensitivity to noise both strongly affect the 'annoyance' of a noise. [42] Sound levels as low as 40 dB(A) can generate noise complaints [43] and the lower threshold for noise producing sleep disturbance is 45 dB(A) or lower. [44]
The big three in sleep sounds are white noise, brown noise, and pink noise, but there are many other noise types, including purple noise, gray noise, and even black noise (a.k.a. good ol ...
Catfish of the families Loricariidae, Callichthyidae, and Scoloplacidae absorb air through their digestive tracts. [5] Lungfish , with the exception of the Australian lungfish, and bichirs have paired lungs similar to those of tetrapods and must surface to gulp fresh air through the mouth and pass spent air out through the gills.
