Summary
This study reveals individual preferences for head-fixed or trunk-fixed reference frames in determining the subjective "straight ahead" position. Brain asymmetry may influence spatial perception and the neural representation of space.
Area of Science:
- Neuroscience
- Spatial Perception
- Human Physiology
Context:
- Neural systems represent space using various reference frames.
- Understanding the subjective 'straight ahead' position is crucial for spatial navigation.
- Previous research highlights the role of body-fixed and external reference frames.
Purpose:
- To identify the specific reference frame used for the subjective 'straight ahead' position.
- To investigate how head deviation affects the perceived 'straight ahead' orientation.
- To explore potential links between head-fixed/trunk-fixed frame preference and brain asymmetry.
Summary:
- Experiments measured deviations in the subjective 'straight ahead' from the objective position with head turns.
- Individual subjects showed consistent preferences for either head-fixed or trunk-fixed frames.
- Observed differences in perceived 'straight ahead' based on head turn direction suggest brain asymmetry in spatial processing.
Impact:
- Provides insights into the neural basis of spatial orientation and self-reference.
- Contributes to understanding individual differences in spatial perception.
- May inform future research on neurological conditions affecting spatial awareness and balance.

Position and Displacement
The position of an object defines its location relative to a convenient frame of reference at any particular time. A frame of reference is an arbitrary set of axes from which the position and motion of an object are described. Earth is often used as a frame of reference, and we often describe the position of an object as it relates to stationary objects on Earth. For example, a rocket launch could be described in terms of the position of the rocket with respect to Earth as a whole. On the other...

Non-inertial Frames of Reference
A reference frame accelerating or decelerating relative to an inertial frame is a non-inertial frame. To help understand this, consider what taking off in an airplane, turning a corner in a car, riding a merry-go-round, and the circular motion of a tropical cyclone all have in common. All these systems are accelerating, decelerating, or rotating relative to the Earth; hence, they all are non-inertial frames. All these systems exhibit inertial forces, which merely seem to arise from motion,...
Inertial Frames of Reference
Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with constant...
Position-effect Variegation
In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.
Anatomical Positions
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...
