In order to affect brain (neuronal) activity, sensory stimulation must be within the frequency range of roughly 0.5 to 25 hertz (Hz) [citation needed]. Touch, photic and auditory stimulation are capable of affecting brain wave activity. A large area of skin must be stimulated to affect brainwaves, which leaves both auditory and photic ...
Histamine has two basic centres, namely the aliphatic amino group and whichever nitrogen atom of the imidazole ring does not already have a proton. Under physiological conditions, the aliphatic amino group (having a pK a around 9.4) will be protonated, whereas the second nitrogen of the imidazole ring (pK a ≈ 5.8) will not be protonated. [11]
The manifestations of histamine intolerance are usually systemic, affecting the entire body; still, these symptoms are often sporadic and non-specific. [5] [6] [7] The onset of symptoms is usually shortly (within a few hours) after specific food or drink consumption, and subsequent remission usually happens in 4-8 weeks of dieting, [8] that is excluding food that causes the onset of symptoms.
The psychology of music, or music psychology, is a branch of psychology, cognitive science, neuroscience, and/or musicology.It aims to explain and understand musical behaviour and experience, including the processes through which music is perceived, created, responded to, and incorporated into everyday life.
The neuroscience of music is the scientific study of brain-based mechanisms involved in the cognitive processes underlying music. These behaviours include music listening, performing, composing, reading, writing, and ancillary activities. It also is increasingly concerned with the brain basis for musical aesthetics and musical
In the brain, it is believed that the right hemisphere better handles meter, while the left hemisphere better handles rhythm. Scientists have studied patients with brain lesions in their right temporal auditory cortex and realized that they were unable to "tap a beat or generate a steady pulse". [4]
Neuronal activity at the microscopic level has a stochastic character, with atomic collisions and agitation, that may be termed "noise." [4] While it isn't clear on what theoretical basis neuronal responses involved in perceptual processes can be segregated into a "neuronal noise" versus a "signal" component, and how such a proposed dichotomy could be corroborated empirically, a number of ...
[1] [2] Histamine is a neurotransmitter involved in various physiological processes. There are four main types of histamine receptors: H1, H2, H3, and H4. H1 receptors are linked to allergic responses, H2 to gastric acid regulation, H3 to neurotransmitter release modulation, and H4 to immune system function. There are four known histamine ...
