Long-term Depression01:03

Long-term Depression

2.6K
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.

Area of Science:

  • Neuroscience
  • Space Medicine
  • Human Physiology

Background:

  • Deep space environments present unique risks to the central nervous system (CNS).
  • Current low-Earth orbit (LEO) missions have shorter durations than planned deep space missions (up to 3 years).
  • Astronaut performance and well-being are threatened by CNS risks in space.

Purpose of the Study:

  • To review evidence on CNS implications for long-duration deep spaceflight (LDDS).
  • To highlight the need for further research in space neuropsychology.
  • To propose a multifactorial neuropsychological approach for assessing risks.

Main Methods:

  • Review of recent evidence and historical spaceflight case studies.
  • Integration of cognitive and motor functions, neuroimaging, and biomarkers.
  • Analysis of behavioral changes, mood, and affect.

Main Results:

  • The deep space environment poses simultaneous risks to CNS functioning.
  • Performance variability and subjective experiences are influenced by multiple factors.
  • Existing data necessitates a comprehensive neuropsychological assessment strategy.

Conclusions:

  • A neuropsychological approach is vital for long-duration deep space missions.
  • Further research is recommended to develop specific space neuropsychology investigations.
  • Understanding CNS risks is critical for astronaut health and mission success.
