Document Summary
Lecture 1- goals of workshop: memory and learning. A. 2. memory and learning require repeated long term interactions between these cells. A. 3. memory is storage- long term vs. short term and long term potentiation (ltp: long term potentiation. As a synapse becomes active, chemical signals are sent from one neuron to the next. As activity increases at a synapse, the neuron receiving the signal upregulates. These receiver proteins persist for up to several weeks (b. 4. c. 1) It activates more proteins that can receive that. B. 5. ltp/ memory formation is facilitated by organization signals (nmda and ampa) Chunking - learning sets of related info: basic structure of brain is determined by genetics as an embryo (embryonic, basic structure of a brain involves. B. 2. signal transduction- when expression occurs: neuronal plasticity = nervous system modified after birth (changes are activity dependent) C. 2. b) lots of activity = many connections lack of activity lose connections. C. 3. multiple synapses active- strengthens response at all synapses.
