Summary
Piano playing experience can alter motor asymmetry and hand preference. Long-term musical practice demonstrates that arm selection is not fixed but can be modulated by learned skills.
Area of Science:
- Neuroscience
- Motor Control
- Human Movement Science
Background:
- Motor lateralization refers to the functional or anatomical asymmetry between the left and right sides of the body.
- Functional motor asymmetry is known to be influenced by various factors, including musical practice.
Purpose of the Study:
- To investigate whether piano playing experience modulates motor asymmetry.
- To determine if musical practice leads to altered hand selection patterns, reflecting changes in handedness.
Main Methods:
- Two groups of right-handed individuals (piano players and non-piano players) participated.
- Participants performed reaching tasks in frontal space with both arms.
- Motor performance and arm preference were assessed for each arm.
Main Results:
- Participants with piano playing experience exhibited reduced interlimb asymmetry compared to non-piano players.
- Piano playing experience was associated with an altered pattern of arm preference.
Conclusions:
- Arm selection, or handedness, is not solely determined by biological factors.
- Long-term piano playing can modulate and alter functional motor asymmetry and arm preference.

The development of self in children is deeply rooted in social interactions, mainly through stages of play and structured games. These stages, outlined by sociologist George Herbert Mead, illustrate how children progressively learn to understand and adopt social roles, forming a cohesive sense of self.The Play Stage: Imitation and Simple Role-TakingIn the early years of childhood, the play stage is characterized by imitative behavior, where children engage in role-playing based on familiar...

01:28Lateralization
1.0K
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

33.3K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

A difference amplifier, a crucial component in numerous electronic devices, ideally amplifies only the difference-mode signal, which is the difference between two input signals. However, in practical circuits, the output voltage depends on both the differential gain and the common-mode gain.
The ratio of differential gain to the common-mode gain is defined as the common-mode rejection ratio (CMRR). This ratio quantifies the ability of operational amplifiers (op-amps) to reject common-mode...

Theories play an essential role in organizing patient care. Theories refer to a proposed or followed belief, policy, or procedure that is the basis for action. Nursing theories are knowledge-based concepts that guide nurses' actions, influence nursing education and practice, and allow nurses to care for their patients.
Theories provide a perspective to assess patients' conditions and organize data and methods. They also assist in analyzing and interpreting information. They represent a...

01:28Equivalent Circuits for Practical Transformers
1.4K
The practical equivalent circuits of single-phase two-winding transformers exhibit significant deviations from their idealized versions due to the inherent properties of winding resistance and finite core permeability. These properties result in real and reactive power losses, affecting the transformer's performance. Understanding these deviations is crucial for designing more efficient transformers.
In a practical transformer, each winding exhibits resistance and leakage reactance. The...
