The shaken complement has a ability to change formed on experience. This plasticity is suspicion to underpin a arrangement and retrieval of memories. How plasticity of particular neurons minister to schooled function is a fundamental, and unanswered doubt in neuroscience. The journal Neuron, Yale scientists uncover that dual plasticity mechanisms act within a singular neuron to demonstrate a memory in a worm C. elegans.
C. elegans can be lerned to cite a temperature, and a Yale team, led by neuroscientists Daniel Colón-Ramos and Josh Hawk, complicated what happens during a mobile turn when animals learn to cite a new temperature. They found that a feeling neuron in a worm can confederate dual plasticity mechanisms to beam schooled behavioral preferences. Sensory instrumentation allows a neuron to act as a arrange of compass, revelation a worm that approach it is temperament on a heat gradient. Presynaptic plasticity acts as an “information gate” that, formed on schooled behavior, governs either heat information is relayed to other neurons or not, thereby determining a movement. Together, these mechanisms emanate a single-cell proof complement that explains how a animal both senses temperature, and responds to it formed on a prior memory.
“Our work shows that any particular neuron is able of behaving as a computer, integrating plasticity mechanisms to routine information that trigger formidable behaviors,” pronounced Colón-Ramos.
