Prior to megagametogenesis, a developing embryo undergoes meiosis during a process called megasporogenesis. Next, three out of four megaspores disintegrate, leaving only the megaspore that will undergo the megagametogenesis. [3] The following steps are shown in Figure 1, and detailed below. The remaining megaspore undergoes a round of mitosis.
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.
A megaspore mother cell, or megasporocyte, is a diploid cell in plants in which meiosis will occur, resulting in the production of four haploid megaspores. At least one of the spores develop into haploid female gametophytes, the megagametophytes. [1] The megaspore mother cell arises within the megasporangium tissue.
During megasporogenesis, a diploid precursor cell, the megasporocyte or megaspore mother cell, undergoes meiosis to produce initially four haploid cells (the megaspores). [1] Angiosperms exhibit three patterns of megasporogenesis: monosporic, bisporic, and tetrasporic , also known as the Polygonum type, the Alisma type, and the Drusa type ...
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).
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.
Biomusicology is the study of music from a biological point of view. The term was coined by Nils L. Wallin in 1991 to encompass several branches of music psychology and musicology, including evolutionary musicology, neuromusicology, and comparative musicology. [1] Power of Music by Louis Gallait.

Music psychology uses the tools of musicology and psychology to explain and understand musical behavior and experience, including the processes by which music is perceived, created, responded to, and incorporated into everyday life.
