  1. Dendrites -short fibers (surrounding the cell body) that receive messages Axon Neuron Ends Cell Body

  2. Dendrites -short fibers (surrounding the cell body) that receive messages Axon-- long fiber (extending from the cell body) that transmit messages through the ends of neurons to other neuron dendrites. Neuron Ends Cell Body

  3. Neuron Ends – dendrite-like fibers that connect to other neuron dendrites Cell Body axon synapse neurotransmitters receptors dendrite

  4. Dendrites Axon Neuron Ends Cell Body Rule 1: New dendrites, synapse, and neural networks grow only from what is already there.

  5. Rule 1: Dendrites, synapse, and neural networks grow only from what is already there. (Smilkstein) This is why activating prior knowledge in the construction of meaning is so important. The newly grown dendrite represents learning. The black dendrites represent prior knowledge

  6. Dendrites -short fibers (surrounding the cell body) that receive messages Axon-- long fibers (extending from the cell body) that transmit messages through the ends of neurons to other neuron dendrites. Neuron Ends Cell Body 1. Incoming sensory information is received by the Dendrites. 2. It then travels down the Axon as an electrical signal and is then transmitted through the ends of neurons (using chemical neurotransmitters) to other neuron dendrites which are specifically related prior knowledge. 3. Rule 1: New dendrites, synapse, and neural networks grow only from what is already there.

  7. (1)Constructing meaning, that is, growing new dendrites is just a third of the story if we want to (2)retain the new learning and (3)be able to use it. The newly grown dendrite represents learning and is learning. The most forgetting occurs within the first 24 hours. While you sleep dendrites that have not been strengthened during the day are reabsorbed (lost).
