Brain connectivity improves human aesthetic responses to music

Brain connectivity improves human aesthetic responses to music Abstract: 1. white matter connectivity between sensory processing areas in the superior temporal gyrus and emotional and social processing areas in the insula and medial prefrontal cortex explains individual differences in reward sensitivity to music. 2. findings provide the first evidence for a neural basis of individual differences in sensory access to the reward system, and suggest that social–emotional communication through the auditory channel may offer an evolutionary basis for music making as an aesthetically rewarding function in humans. 3.carried out by -- Using a combination of survey data, behavioral and psychophysiological measures and diffusion tensor imaging, Conclusion: Results from diffusion tensor imaging show that white matter connectivity between auditory perceptual regions (pSTG) and regions of the brain important for emo- tional and social processing (aIns, mPFC) reflect individual diffe...

Desensitization

1.Drug desensitization refers to two related concepts. First, desensitization may be equivalent to drug tolerance and refers to subjects' reactions (positive or negative) to a drug reducing following its repeated use. 2.desensitization, which refers to a biochemical effect where individual receptors become less responsive after repeated application of an agonist . This may be mediated by phosphorylation , for instance by beta adrenoceptor kinase at the beta adrenoceptor . 3.Desensitization is a result of either of continued presence of agonist specific for that receptor (homologous) or of a result of either a class of agonists working toward a “common goal” (heterologous desensitization). 4.There are two known mechanisms for desensitization (see Figure 10.19). a)decrease in response brought about by the covalent modifications produced by receptor phosphorylation and is quite rapid (seconds to minut...
