How Motor Responses Influence Sensory Neuron Output

publication Evidence: moderate

Author Information

Author(s): Emilio Salinas

Hypothesis

Monotonic sensory inputs are favored when monotonic motor outputs are desired.

Conclusion

The study suggests that the shapes of optimal sensory response curves should match the type of motor output they are linked to.

Supporting Evidence

  • Monotonic sensory responses are more efficient for driving desired motor outputs.
  • The model predicts that sensory responses should match the type of motor output.
  • Initial data from animal experiments support the proposed model linking sensory and motor responses.

Takeaway

This study shows that how our body moves can change how our sensory neurons respond to things we see or feel.

Methodology

The author constructed a mathematical model linking sensory neurons to motor neurons to explore response curves.
