講題：Proprioception and touch in mammals and cephalopods
地點：傳統醫學大樓甲棟二樓演講廳 （陽明校區）
Abstract:
Proprioception and touch are fundamental sensory modalities that allow animals to interact with their environment and monitor their own body. In mammals, these senses are mediated by specialized mechanoreceptors such as muscle spindles, Golgi tendon organs, and cutaneous receptors, which transmit information to the central nervous system via dedicated somatosensory pathways. Proprioception enables the brain to perceive limb position and movement, while touch conveys external mechanical stimuli such as pressure, vibration, and texture. On the other hand, cephalopods—such as octopuses and cuttlefish— also display remarkable sensorimotor control and haptic exploration, suggesting they possess analogous systems for proprioception and touch. Recent studies indicate that cephalopod arms contain distributed mechanosensors and exhibit local processing, allowing independent movement and environmental feedback. Comparing mammalian and cephalopod mechanosensation not only reveals evolutionary convergence and divergence in sensory strategies but also informs the design of bioinspired soft robotics and sheds light on the neural basis of embodiment.
