Neuronal response to the temperature changes in Onchidium

TNTakako Nishi

Key Points

  • This study aims to examine how neurons in Onchidium respond to temperature changes in their environment.
  • Conducted neural observations in Onchidium under varying temperature conditions: reduced by 2-3 ℃.
  • Identified and monitored the electrical activity of the neurons, particularly focusing on neuron Ip-1/2 and neighboring autoactive neuron.
  • Neuron Ip-1/2 depolarized in response to temperature changes, firing at threshold levels.
  • Repetitive spikes in the neighboring autoactive neuron ceased with similar cold stimulus, indicating distinct responses between neuron types.

Abstract

Neural responses in Onchidium were observed when the temperature of the bathing solution was lowered by 2 - 3 ℃ from room temperature. The identified neuron Ip-1/2 depolarized in parallel with temperature changes and fired when it reached threshold, whereas repetitive spikes ceased in response to the same degree and time course of the cold stimulus in the autoactive neuron neighboring Ip-1/2. These findings will be crucial for advancing understanding of temperature homeostasis at the cellular level in intact cells.
