Summary

Human spatial orientation in altered gravity was studied using subjective visual vertical (SVV) and subjective horizontal body position (SHP) tests. Findings suggest otolithic output normalizes, while somatic gravity sensors do not, in microgravity.

Area of Science:

  • Neuroscience
  • Human Physiology
  • Space Biology

Background:

  • Understanding human spatial orientation is crucial for spaceflight and neurological research.
  • Altered gravitational environments significantly impact sensory perception and motor control.

Purpose of the Study:

  • To investigate human spatial orientation during parabolic flights in microgravity.
  • To compare perceived orientation in microgravity with normogravity (1g) and hypergravity (2g) conditions.
  • To develop and test theoretical models of subjective static orientation.

Main Methods:

  • Measurements of subjective visual vertical (SVV) using a luminous line.
  • Subjective reports of apparent vertical with eyes closed.
  • Comparison of inflight data with baseline measurements of subjective horizontal body position (SHP).

Main Results:

  • Baseline data (1g, 2g) and microgravity data were collected.
  • Theoretical models were developed and compared against experimental data.
  • A model assuming normalized otolithic output and non-normalized somatic sensor output fit the data well.

Conclusions:

  • The otolithic system appears to normalize its output in microgravity.
  • Somatic gravity sensors do not exhibit the same normalization, influencing perceived orientation.
  • These findings contribute to understanding sensory integration in altered gravitational states.
