Alnus serrulata is a large shrub or small tree that may grow up to 2.5–4 m (8.2–13.1 ft) high and 15 cm (5.9 in) in diameter. The scientific name originates from alnus which is an old name for alder; serrulata points to the finely-toothed leaf margins which it possesses. It takes about 10 yrs to mature.

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.
Music has been shown to consistently elicit emotional responses in its listeners, and this relationship between human affect and music has been studied in depth. This includes isolating which specific features of a musical work or performance convey or elicit certain reactions, the nature of the reactions themselves, and how characteristics of the listener may determine which emotions are felt.
The cognitive neuroscience of music represents a significant branch of music psychology, and is distinguished from related fields such as cognitive musicology in its reliance on direct observations of the brain and use of brain imaging techniques like functional magnetic resonance imaging (fMRI) and positron emission tomography (PET).
Cognitive musicology can be differentiated from other branches of music psychology via its methodological emphasis, using computer modeling to study music-related knowledge representation with roots in artificial intelligence and cognitive science. The use of computer models provides an exacting, interactive medium in which to formulate and ...
The Betulaceae are believed to have originated at the end of the Cretaceous period (about 70 million years ago) in central China.This region at the time would have had a Mediterranean climate due to the proximity of the Tethys Sea, which covered parts of present-day Tibet and Xinjiang into the early Tertiary period.
