Summary The Adaptive Brain

A snapshot of the summary - The Adaptive Brain

• LC 3 Synaptic transmission

• Name 3 characteristics of electrical synapses

  • Fast
    
  • bi-directional
  • tight binding dues to connexons
    
• Synaptic vesicle release needs or doesn't need app form the mitochondria

  Need
• Where are the synaptic vesicles located

  At the active zone or the ready release pool
• What is the cycle for synaptic vesicles recyclin

  1. Docking
     
  2. priming
  3. exocytosis
  4. endocytosis
     
• What is the function of synaptotagmin

  Senses Ca+ and triggers fusion

• LC 1 Purves Chapter 2

• Why are neurons poor generators and conductors

  They are made out of lipids
• The Na+/K+ pumps uses ... Atp to get Na out and ... Atp to get K+ in

  2 and 3

• LC 2 Action potentials are generated by ion currents

• Name the phase of an action potential

  1. Resting membrane potential
     
  2. rising until threshold
  3. depolarization: Na+ and K+ channels open
  4. repolarization: N+ channels begin to close
  5. hyperpolarization: Na+ channels close, K+ still open
  6. back to resting membrane potential: K+ channels are also closed
     
• What does the patch clamp method do

  Micropippet sucks a part of the membrane containing ion channels that allows current

• LC 4 Molecular signaling within neurons

• What are the amplification steps

  Receptor, adenylyl cyclase, protein kinases
